TATRA trucks are famous for having a "Central tubular frame with independent suspension" There are even a few vintage tippers that drive with the original tires, which are specially shaped so that they have profile on the flanks so that they can drive unloaded when the wheels are almost at a 30 degree angle, not breaking down too quickly due to too much wear
The Tatra design is actually a swing axle design so that the whole one side axle pivots at the central driveshaft that is housed in a tubular backbone that is immensely strong in torsion and bending. This means that the cab and the bed are one rigid unit that doesn't have to rely on chassis flex like the Mercedes trucks. The Tatra engines are air-cooled and of modular design allowing 8, 10 and 12 cylinders. They were very popular support trucks for Paris-Dakar competitors with a rumoured 1000 - 1200hp output

@@zdenekdolezal9646 That is what I thought I described? The axles are swing axles as they are connected to the central driveshaft within the central spine and the wheel is fixed perpendicular to the axle.

The principle of swing axles was popular in bygone decades with the most famous exponents being 1959 et sec Mercedes 300SL (gullwing) and the Volkswagen Beetle (air-cooled). The backbone design is exclusive to Tatra IIRC as most other trucks use a separate ladder frame that they either try to make rigid or flex like Mercedes Unimog and other Merc trucks.
@@clivewilliams3661 then i misunderstood. My point was just half axle for each wheel, not one long axle for both wheels somehow joined to the tube in the middle. To wasn't obvious for me how you desceibed it, so I tried to clearify.
One last point, the Steyr-Puch Pinzgauer uses a very similar system of backbone chassis/transmission tube with dual crown wheels and swing axles. Both the Tatra and the Pinzgauer have very strong off-road capabilities in military applications that has filtered down to civilian use.
Tatra is one of the oldest car makers on Earth, they made first aerodynamic production car in the world back in 1934 and since 1999 they are making only trucks and military vehicles.
You know a true motor when he can appreciate all forms of motorsports not just his favorite from his home country and that's what keeps me coming back to this channel!
Thank you! I can’t get enough of all these different Motorsports in different settings and countries!! Quite frankly it’s refreshing, I’ve watched too much nascar haha
@@IWrocker if theres one thing that unites all gearheads is we like anything with a motor to do something dangerous and/or stupid in lmao I highly respect you and your channel bud keep up the great content
The thinking behind the Tatra transmission style is if you run a central axel longitudinal from the engine to the back, you can place as many differentials as you want as long as the wheels don't touch each other therefore you can make 10x10 or 12x12 for example. Plus the fact that the arms to the wheels pivot from a central point and are not perpendicular to the ground, it gives you better ground clearance and less complicated suspension settings with fewer parts.
@@IWrocker It gets better. The differential gearboxes are arranged in such a way that a spur gear rides on a pivot against one of two ring gears... it's complicated to explain, but there are no U-joints, the axle pivots along that central gear's center and keeps the driven gear in alignment.
Hill climb usually means, they try to get up as far as they can, on a hill that is basically impossible to master completely. Look at the motorbike hill climbs, they are even crazier.And Mohelnice is in the Czech Republic
The 8 wheel trucks (Tatra 813 and 815) have a 5 speed base transition with auxilliary Hi/Lo gear you can preselect on the gear lever. On flat road you usually start at 2H and go 3L,3H,4L,4H,5L,5H. There is also "Rabbit/Turtle" gear you have to select at a standstill. You were right with the camber that straightens with the load. Current Tatra Phoenix suspension has an air component that helps straightening the camber at different loads.
Resident Czech person again here :D It is in our country we call it Truck Trials and Mohelnice is a little town about 10k inhabitants and trials are done in closed surface mine. TATRA is so OP offroad it was designed for military they just do these things with them
That smaller car just before the Jeep was a Suzuki, very popular for offroading in Europe at least, it's usually either a SJ410 (1.0 liter engine) or SJ413 (1.3 liter engine) But they're also called Suzuki Samurai in the US I believe.
The first truck is the Tatra 813 8x8 KOLOS, which was intended primarily for the Czechoslovak People's Army at the time and had a maximum pulling power of up to 100 tons. Then there are the Tatra series 815 6x6 and 8x8, which were not only for the military but also for the civilian market, the gearboxes will certainly be modified, but I don't want to lie.

I've been patiently waiting for you to find this video. I knew you would love it.😁 Another good video to look for is where they are racing the 8WD trucks up the walls of a quarry.
This is truck trial event. These are only cuts from whole 3 day event, where you have multiple classes of trucks (with or without turbo, with different wheel config etc) and different tracks, where you have limited time to enter "gates" from direction that is marked on them. Different driveres enter truck with different technics and ideas. I love these! Visiting them for about 10 years :D
Tatra Suspension is independent for every wheel on central tube and tire pressure can be controlled to, They win severall Paris Dakar rallies. Jeeps are available in Europe predominiately with diesel !
They export them tp Alaska but some dushbag decided that Tatra air-cool 10L 10 cylinder engine is not good for frozen tundra ....so they put in Detroit diesel ..... and they froze on them
This is from one of the European truck trials - basically a series of very tricky marked courses they have to try and conquer. The further they get the more points they get, or lose, depending on the scoring method. These are HUGE in Europe and there are many factory, and factory backed, teams. The swing axles used by TATRA is very unusual, those interested in truck design should check it out.
The goal is to go as high as possible, judges mark youre highest spot (a bit like in long jump competition) If you get to the top you win, if more than one competitor get to the top, the quickest win. As soon as you start to wheel spin and not move anymore you have to stop and youre try is over. I believe each competitor have multiple tries.
Good video dude, I've been watching your vids for a while, I'm an expat from blighty, love those ausies, God bless you and your family, keep on doing your spectacular videos,
I love how these engines are so versatile they can run on just about anything. If you have a stick of butter you could probably stick it in the tank and get it going again.
Tatra has been around since the model T. The first rolling heavy coal looks like a Scania & you also have KAMAZ trucks there. Kamaz, which you would know Ian, is in partnership with redbull to create the Dakar winning monsters with turbos the size of wheelie bins
Hi there. I think that's the final part in to the end of the circuit of obstacles. Usually they have to cross a rocky creek and other dificult obstacles. By the way I'm European ( Lisbon Portugal)and I love American trucks. They are made more to speed across long highways and Roads. Not to climb. Take care ✌
On that steep climb a Toyota managed only about first 20 ft, two Landrovers not even that. I was challenged at a shorter steep slope in that river valley without any existing wheel tracks, to show if the Suzuki could even get up that. I left open jaws, as I drive up and down without issue several times then added to the amazement by stopping midway, handbrake on stepping out and saying to the gathered group surely they have something a bit harder. Then re-entered and proceeded from stop up the rest of the way, then several more forward and backward runs stopping and restarting. One member with a V8 engine tried it by brute force/speed, got most of the way up and with locked wheels slid at speed back down digging his towbar hard into the ground at the bottom others tried but barely got all 4 wheels onto t he slope before scrabbling tyres. For good measure I completed two more up down runs. The joker admitted I was right to not do the long hill with blocking logs though suggested that likely I would have had no issue safely reversing down. Over my time in Sydney my Suzuki got several others in the same, and I was invited on special extra hard trips of limited number of vehicles and experienced drivers only. Throughout that time the Suzuki kept outperforming larger vehicles on trips. Too much to go into on these comments. Still regret in 1980 upgrading to larger size 4WD Nissan Patrol , to now a Landcruiser Series 80 getting on with 29 years on the road.
Well when the Zuki weighs less than a ton compared to about 2 ton for the average 4x4, most people with common knowledge would know it would be less inclined to dig itself in. Over the years I've seen them do many amazing things, like sand dunes etc that landcruisers get stuck in. That being said they lack in water crossings, seen about 4 get carried away by currents other 4x4s idle through
@@joshthomas2536 actually was 750kg gross loaded weight, 250kg load capacity. Two heavy adults could exceed it permissible load. Real fun to throw around, so much so that several review journalists returned damaged vehicles after repeatedly purposeful spinning out thrashing through corners sliding off the road, all was such joy compared to manhandling typical 2 ton steel hulks. Bad was its narrow width, that like the Haflinger 4WD also a tiny 2 cyl Austrian vehicle, assembled in Victoria from imported kits, side rollovrrs were common. The massive 56:1 low gear 1st reduction gave theoretical torque at each wheel exceeding max mass. Of course different prevented that, but given traction in theory could climb vertically. I have 8mm movie of a Suzuki trying to climb up a large house sized rock. The driver only had to abandon the climb because he was standing vertical on rear wheels about to back flip. On large boulders near Warragamba dam, that US Sydney main water storage, the Suzuki chambered along more like a mountain goat. The short wheelbase and light weight also had disadvantages. The short nature and especially NSW tracks were often granit gravel to easily cause loss of traction and often mound and diverting gully, caused Suzuki to need to climb the steeper approach side of mound section, in climbing hills on tracks, resulting in both front and rear wheels on the steeper mound side slope before crossing the peak. Where larger 4WD would have front over the peak as rear wheels started climbing. Si Suzuki would be left scrabbling in loose gravel spinning all four wheels. Even stopped by loose gravel on hill climbing by larger tree roots, then spending time spinning and sliding back and forth against said root. Usually made it after removing loose surface gravel, and especially knowing and proper driving technique minimised that. On the sandunes at Newcastle bight the power and speeds in gears became a limit too. With fast run up the bigger 4WDs conquered many dune faces, that little Suzi just started on and dug in, with sand even sliding down over the bonnet (hood for US). However on a saddle ridge between two tall dunes, three vehicles had to be winched out. Yet my Suzi climbed the side of that saddle ridge, from side across the top down the other side. The wheels were turning in second gear low range but like clockwork driven a TICK forward rotation then stopped as opposite wheel would do TICK forward, all four wheels progressing in tiny increments over 20 minutes making a climb across with total height near 50 ft base to top. Another part of that dunes trip allowed under special government permit, as normally only beach access for surf fishing allowed, was fuel use. My Suzi did the weekend trip Newcastle, dunes and back on its 30 liter tank with near 15% reserve. Most larger vehicles needed jerry cans of fuel unless having secondary fuel tanks, and one Landrover burned through 120 liters fuel, needing an extra 20 L jerry can of fuel from another vehicle to make it back to a petrol station. Long trips were awkward with around 350 to 400km range depending on how hard the terrain, and on highway how fast you pushed it. Quite normal was max speed redlined at 80kph, and that was engine screaming at around 7500 rpm. Gets tiring on near 800km or 1200 km highway run Sydney to Melbourne depending inland Hume Hwy or coastal Princes Hwy. Also bothersome on long highway hills trucks would require you to pass them or drop also to lower speeds then they roared past downhill and the flat stretches as you were stuck at 80kph max. Same for cars with caravans or boat trailers. On ghe whole though I would like my old two stroke Suzi back if that were possible have many fond trip memories, inspite of its clear limitations on load capacity, speeds and other things. The later evolution to four stroke engines wider track etc to the model "Stockman" version is just not the same. Though as a small second vehicle could be nice. A fully EV version might also be of interest.
These Truck trials are not primarly about hill-climbing - though I admit this is a fun part. The goal is to drive a flaged out parcour with only a limited number of changing of direction (forward/backwards) permitted. Time counts, but also score and penalty points. There are targets they have to drive through without touching the poles and there are other targets (often on top of a climb) that only have to passed with a part of the truck (obviously usualy the bumber).
They would likely be manual MR setups, so something around an Isuzu NPR 1250 size. The articulation on some of those trucks looks to be independent lateral swing arms, like the front of an old F100, which is why there is positive camber. The Uni Mogs use the chassis for flex and have portal axles.
Clearly getting to see the wide range of motorsports around the world, far beyond pure circuit racing and drag strip. These special purpose "offroad" working trucks for forestry , agriculture, military and other dedicated needs are quite capable. Other than this are the very impressive obstacle events that include steep slopes deep mud deep water, boulders, cement blocks of significant height, sharp approach & departure angle, logs , side slopes and all kinds of other hard obstacles. On such steep slopes it is one of the big features that separate many vehicles. Much fun for 4WD vehicles where sonn it is vehicle more than raw power that determines the result. The suspension, tyres diff lock or limited slip gear ratios and even chassis flex, mass distribution all heavily determine performance. My first ever own vehicle was one that initially got lots of laughs and ridicule by prior 4WD owners. Soon that laugh was turned to scowls amazement and from some even grudging praise. I first ever saw Suzuki LJ20 4WD in American 4x4 magazine, showing these used in steep muddy mountain forests of Papua New Guinea. Also some articles about some sold in the region of US Rockies. Those were powered by two stroke 2 Cylinder 360 cc engines. After a couple of years I became aware of the newer LJ50 becoming available in Australia. It had a two stroke 3 cylinder 540cc engine, still separate oil injection and a 30L standard gasoline fuel tank. With that limited fuel capacity a bit limiting like many EV cars now, but still reasonable with upwards of 350km offroad 4WD range, and even over 400km on road. First shipments to Australia were a mere 150 or 200, and largely promoted for small farm general utility vehicle. I was captivated and borrowed from bank and parents the needed $2799 value, ended up with second last unsold one in Melbourne, actually just outside Melbourne in a rural farm area from a farming supplies tractor service and stock feed dealership. I took an amazing test ride where the dealership mechanic demonstrated deep mud excellent climbing, stop, restart on water channel embankment of over 45° angle. I was so taken I signed even before my bank confirmed the loan the only actual loan in my life. I had a Yellow softtop/canvas top and doors. Soon ran up kilters quickly going exploring 4WD forestry tracks. The limited warantee of only 10 000km and 3 months was completed on the same day. Yes that warantee put many of in early times. I soon was in for my third service, and as the demo dealership vehicle was missing a farmer with beat-up old Landrover was there asking for a demo, getting angry made to wait. I offered to drive him round the demo I had . One part needing an access key for a paddock gate. Anyhow with farmer in the passenger seat and one of his teen sons in the rear tray did all the usual slow low gear speeds allowing walking along beside the vehicle idling along over rough power fields even walking around the vehicle rolling along, then the steep water channel embankment up/down, stop in mid slope, keep going up forward and even stop in descent and restart reversing to top. The farmer very impressed as he realised by many years of Landrover driving that would neither manage that slope nor stop and continue from stop on that slope. On the big paddock I dropped both wheels on one side into a muddy ditch that bogged progress right there. The farmer convinced we were permanently stuck. Well with a bit of low gear and jiggling steering I soon drove back out of the ditch. I then made a serious mistake . In high grass area to half the side windiw height I saw some white pegs in small cleared patches. In manoeuvring around several, I failed to look forward, at farmer gesture I saw a large gaping hole, as I crashed my Suzuki across the hole. Front bumper imbedded and somewhat buckled on far side of the hole front wheels in the air and rear wheels on the near side of the hole. Climbing out I could walk to the other side of the hole. I admitted that looked dire, all this onto of some huge concrete lid apparently a huge drainage pipe had been layed across the paddock. Observing that really the vehicle was on its chassis rails and rear tyres with bumper really not supporting much we noted that lifting the front applied more pressure on rear tyres. With farmers son hanging off my rear mounted spare wheel, farmer supporting the front under the engine by the cross member behind bumper, I actually reversed off that hole. I apologised but the farmer was elated by the vehicle. He actually signed for five Suzuki's that very day, for his three farms, and six sons. Sadly the defeat never gave me any reward only a thank you for the demo. On first 4WD club trip I was advised it was not good for that Suzuki toy, the trip would need a "Proper" 4WD.. I went anyway and during the trip made every part without issue, even had to return down a steep climb as the trip leaders Toyota, even with 4 wheels fitted with tyre chains failed to get up after nearly half dozen attempts, we had to go on via alternative tracks. Anyhow the next club magazine featured a comedic sketch of the Suzuki with a very praising text like "Go Jimny " tearing through rough hill. The group learned respect for the vehicle. Within that first year many 4WD reviews had nothing but praise. I had a shortvterm became 1 1/2 years working in Sydney where my employer arranged for me to contact the local Landrover owners club that also participated in search and rescue and fire fighting, several local district police were also members. My first trip I turned up to at nearly 150km from Sydney , I was told as parts of the trip were hard and that little 4WD Suzuki was fine around farms, not likely to be capable of some of the trip so advised me to wait for a easier weekend trip. Otherwise since the trip was in and out by same tracks I would have to remain at where ever I was not able to go on camp and I could return out when the group would come back by Sunday. I went for the trip and as I expected more than matched requirements. In fact there was on burned clutch and four broken Axel's for larger 4WDs mainly on Landrovers. I learned as previously seen in documentaries Landrovers regularly strip diffs and brake Axel's. I took the challenge by the club joker of driving a deep water crossing between sand/rock bars at a river bend putting water splashing over my engine hood (bonnet as we call it) and only climbing out of the deep water back onto the sand bar dug in and stopped with engine idling up out the water, exhaust bubbling. The joker then tried to show how good a Landrover would do the crossing. Well he made less than half the distance bogged in deep water stalled the engine with water at side windows and engine submerged. . Both had to b e winched out, the landrover needed complete oil change, at camp several got various repairs of broken Axel's. The burned out clutch vehicle finished the trip towed and winched. I was challenged to see how far up a long steep hill I could go I refused as I believed the climb of over 100 yards, as quite possible, but at top were several large logs across the way that would require full reversing down.. continue next comment
i have driven a Tatra that had a 6 speed automatic... with a selective low gear for crawling. it was an absolute beast off road but less so on the blacktop... it drive fine on tarmac but you could tell it wasn't made for it. it was like it wanted dirt and mud... it was fully locked and even though i tried to get it stuck on sand dunes... locking the last diff and airing out all the tires and lifting the suspension to get more ground clearance and it just stopped caring what was in it's way... it just went.
Hi Ian and family. On the Australia theme, look on youtube for "Austen Tayshus - Australiana (Official Uncensored Version)". Ver 'corny' but a big hit back in the day. ;)
I would assume from all the people at the top the trucks are not supposed to go all the way to the top. If those ruts get much deeper they will start bottoming out. Makes me wonder if a tank would make it to the top.
And with the optional anf often fitted additional splitter box creates a 16 speed truck that supposedly at maximum revs in 1st gear is moving at less than walking pace.
You should see the crazy stuff in the oilfeilds Giant oilfield trucks like MOL F7066 and the mercedes Z80 with 68 inch tires hauling a oilrig that has tires that are almost 200 inches Never seen a oil rig on wheels get pulled?
Well there's some wrong information here in the comments....Tatra is company in the czech republic thats correct but the design from the " backbone with independent swing axles" commes from the Austrian designer Hans Ledwinka who worked for Tatra . Now this guy is also responsible for the design where Ferdinand Porsche got his idea from to build the vw beetle...so without Hans Ledwinka there would be no vw beetle. His son Erich Ledwinka worked at SDP ( STEYR DAIMLER PUCH) in Graz Austria where he designed the Steyr-Puch-Haflinger and the steyr puch pinzgauer...bouth with the simmelar backbone independent axle system he took over from his father.

I drove Tatra T815 8x8 at Finnish army and it was cool machines 😎 That what i drive was equipped with 19-litre twin-turbo V12 air-cooled diesel, what a sound it made... There was also V8 and V10 engines debending your power needs. Transmission was 5-speed with splitter = 10-speed. It had also "off-road transfer case", so total 20-speeds. (10 road-speeds and 10 off road speeds) It was also syncro-box (not 1st gear) , so easy shifting up and down. Those Tatras have quite unique central tubular frame, each wheel have their own springs and driveshafts. Watch this: ruclips.net/video/5UkAyAzhmsA/видео.html
well from exerience (I have been in similar ofroad races in the car with one of my friends who is a driver) in these terrain races they drive manual. Automatic is not good for these races because youi loose one of the way to controll the car better (which is what you really need in terrain that is this complicated-also it is much easier to mantain and it lasts longer and there are less problems)

This is from one of the European truck trials - basically a series of very tricky marked courses they have to try and conquer. The further they get the more points they get, or lose, depending on the scoring method.
These are HUGE in Europe and there are many factory, and factory backed, teams.
The swing axles used by TATRA is very unusual, those interested in truck design should check it out.
Finaly my favorite motorsport ! Thanks for reaction !
The goal is to go as high as possible, judges mark youre highest spot (a bit like in long jump competition)
If you get to the top you win, if more than one competitor get to the top, the quickest win.
As soon as you start to wheel spin and not move anymore you have to stop and youre try is over. I believe each competitor have multiple tries.
Good video dude, I've been watching your vids for a while, I'm an expat from blighty, love those ausies, God bless you and your family, keep on doing your spectacular videos,
Thank you so much 👍🎉😎
Good onya mate! Hurry up and come to Australia too
I love how these engines are so versatile they can run on just about anything. If you have a stick of butter you could probably stick it in the tank and get it going again.
The greenies would be hating this. But I think it’s cool.
10:35 wow that shows how steep it really is, crazy.
Totally 😎
Definitely more like this please Ian. Thanks.
Tatra has been around since the model T. The first rolling heavy coal looks like a Scania & you also have KAMAZ trucks there. Kamaz, which you would know Ian, is in partnership with redbull to create the Dakar winning monsters with turbos the size of wheelie bins
the first one was a tatra 813 bro
Mohelnice ! In Czech Republic (state, where was the guy driving that F1 on highway 😀)
oooh yeh.. 8x8 tatra trucks with their aircooled v12 diesels!
Notice none of the crowd at the top looked like they thought they might have to move out of the way 🙂
Haha 😂 good point
Hi there. I think that's the final part in to the end of the circuit of obstacles. Usually they have to cross a rocky creek and other dificult obstacles. By the way I'm European ( Lisbon Portugal)and I love American trucks. They are made more to speed across long highways and
Roads. Not to climb. Take care ✌
On that steep climb a Toyota managed only about first 20 ft, two Landrovers not even that. I was challenged at a shorter steep slope in that river valley without any existing wheel tracks, to show if the Suzuki could even get up that. I left open jaws, as I drive up and down without issue several times then added to the amazement by stopping midway, handbrake on stepping out and saying to the gathered group surely they have something a bit harder. Then re-entered and proceeded from stop up the rest of the way, then several more forward and backward runs stopping and restarting. One member with a V8 engine tried it by brute force/speed, got most of the way up and with locked wheels slid at speed back down digging his towbar hard into the ground at the bottom others tried but barely got all 4 wheels onto t he slope before scrabbling tyres. For good measure I completed two more up down runs. The joker admitted I was right to not do the long hill with blocking logs though suggested that likely I would have had no issue safely reversing down.
Over my time in Sydney my Suzuki got several others in the same, and I was invited on special extra hard trips of limited number of vehicles and experienced drivers only. Throughout that time the Suzuki kept outperforming larger vehicles on trips. Too much to go into on these comments. Still regret in 1980 upgrading to larger size 4WD Nissan Patrol , to now a Landcruiser Series 80 getting on with 29 years on the road.
Well when the Zuki weighs less than a ton compared to about 2 ton for the average 4x4, most people with common knowledge would know it would be less inclined to dig itself in. Over the years I've seen them do many amazing things, like sand dunes etc that landcruisers get stuck in. That being said they lack in water crossings, seen about 4 get carried away by currents other 4x4s idle through
@@joshthomas2536 actually was 750kg gross loaded weight, 250kg load capacity. Two heavy adults could exceed it permissible load.
Real fun to throw around, so much so that several review journalists returned damaged vehicles after repeatedly purposeful spinning out thrashing through corners sliding off the road, all was such joy compared to manhandling typical 2 ton steel hulks. Bad was its narrow width, that like the Haflinger 4WD also a tiny 2 cyl Austrian vehicle, assembled in Victoria from imported kits, side rollovrrs were common.
The massive 56:1 low gear 1st reduction gave theoretical torque at each wheel exceeding max mass. Of course different prevented that, but given traction in theory could climb vertically.
I have 8mm movie of a Suzuki trying to climb up a large house sized rock. The driver only had to abandon the climb because he was standing vertical on rear wheels about to back flip.
On large boulders near Warragamba dam, that US Sydney main water storage, the Suzuki chambered along more like a mountain goat.
The short wheelbase and light weight also had disadvantages. The short nature and especially NSW tracks were often granit gravel to easily cause loss of traction and often mound and diverting gully, caused Suzuki to need to climb the steeper approach side of mound section, in climbing hills on tracks, resulting in both front and rear wheels on the steeper mound side slope before crossing the peak. Where larger 4WD would have front over the peak as rear wheels started climbing. Si Suzuki would be left scrabbling in loose gravel spinning all four wheels. Even stopped by loose gravel on hill climbing by larger tree roots, then spending time spinning and sliding back and forth against said root. Usually made it after removing loose surface gravel, and especially knowing and proper driving technique minimised that.
On the sandunes at Newcastle bight the power and speeds in gears became a limit too. With fast run up the bigger 4WDs conquered many dune faces, that little Suzi just started on and dug in, with sand even sliding down over the bonnet (hood for US). However on a saddle ridge between two tall dunes, three vehicles had to be winched out. Yet my Suzi climbed the side of that saddle ridge, from side across the top down the other side. The wheels were turning in second gear low range but like clockwork driven a TICK forward rotation then stopped as opposite wheel would do TICK forward, all four wheels progressing in tiny increments over 20 minutes making a climb across with total height near 50 ft base to top.
Another part of that dunes trip allowed under special government permit, as normally only beach access for surf fishing allowed, was fuel use. My Suzi did the weekend trip Newcastle, dunes and back on its 30 liter tank with near 15% reserve. Most larger vehicles needed jerry cans of fuel unless having secondary fuel tanks, and one Landrover burned through 120 liters fuel, needing an extra 20 L jerry can of fuel from another vehicle to make it back to a petrol station.
Long trips were awkward with around 350 to 400km range depending on how hard the terrain, and on highway how fast you pushed it. Quite normal was max speed redlined at 80kph, and that was engine screaming at around 7500 rpm. Gets tiring on near 800km or 1200 km highway run Sydney to Melbourne depending inland Hume Hwy or coastal Princes Hwy. Also bothersome on long highway hills trucks would require you to pass them or drop also to lower speeds then they roared past downhill and the flat stretches as you were stuck at 80kph max. Same for cars with caravans or boat trailers.
On ghe whole though I would like my old two stroke Suzi back if that were possible have many fond trip memories, inspite of its clear limitations on load capacity, speeds and other things.
The later evolution to four stroke engines wider track etc to the model "Stockman" version is just not the same. Though as a small second vehicle could be nice. A fully EV version might also be of interest.
These Truck trials are not primarly about hill-climbing - though I admit this is a fun part. The goal is to drive a flaged out parcour with only a limited number of changing of direction (forward/backwards) permitted. Time counts, but also score and penalty points. There are targets they have to drive through without touching the poles and there are other targets (often on top of a climb) that only have to passed with a part of the truck (obviously usualy the bumber).
Zámecký vrch 2017 - David Vršecký a dakarská Tatra-Phoenix,Buggyra
Most of these events are timed at quickest to the top 👍🍺
Hey IWrocker, look up VSCC trial. Crazy brits doing weird stuff in the mud with vintage cars. Just brilliant!
These 8x8 Trucks are Tatra 813 i think it has a V12 aircooled engine with 18 Liters of Displacement 250 hp and 1100 Nm of torque
Someone should take an Aussie Landcruiser over and show them how to get it done 🤣🤣
👍🎉🤣
They would likely be manual MR setups, so something around an Isuzu NPR 1250 size. The articulation on some of those trucks looks to be independent lateral swing arms, like the front of an old F100, which is why there is positive camber. The Uni Mogs use the chassis for flex and have portal axles.
1:12 Tatra 813 8x8 they have aircooled V12 17,6 l 199 kW.
Clearly getting to see the wide range of motorsports around the world, far beyond pure circuit racing and drag strip.
These special purpose "offroad" working trucks for forestry , agriculture, military and other dedicated needs are quite capable. Other than this are the very impressive obstacle events that include steep slopes deep mud deep water, boulders, cement blocks of significant height, sharp approach & departure angle, logs , side slopes and all kinds of other hard obstacles.
On such steep slopes it is one of the big features that separate many vehicles. Much fun for 4WD vehicles where sonn it is vehicle more than raw power that determines the result. The suspension, tyres diff lock or limited slip gear ratios and even chassis flex, mass distribution all heavily determine performance.
My first ever own vehicle was one that initially got lots of laughs and ridicule by prior 4WD owners. Soon that laugh was turned to scowls amazement and from some even grudging praise.
I first ever saw Suzuki LJ20 4WD in American 4x4 magazine, showing these used in steep muddy mountain forests of Papua New Guinea. Also some articles about some sold in the region of US Rockies. Those were powered by two stroke 2 Cylinder 360 cc engines. After a couple of years I became aware of the newer LJ50 becoming available in Australia. It had a two stroke 3 cylinder 540cc engine, still separate oil injection and a 30L standard gasoline fuel tank. With that limited fuel capacity a bit limiting like many EV cars now, but still reasonable with upwards of 350km offroad 4WD range, and even over 400km on road.
First shipments to Australia were a mere 150 or 200, and largely promoted for small farm general utility vehicle. I was captivated and borrowed from bank and parents the needed $2799 value, ended up with second last unsold one in Melbourne, actually just outside Melbourne in a rural farm area from a farming supplies tractor service and stock feed dealership. I took an amazing test ride where the dealership mechanic demonstrated deep mud excellent climbing, stop, restart on water channel embankment of over 45° angle. I was so taken I signed even before my bank confirmed the loan the only actual loan in my life.
I had a Yellow softtop/canvas top and doors. Soon ran up kilters quickly going exploring 4WD forestry tracks. The limited warantee of only 10 000km and 3 months was completed on the same day. Yes that warantee put many of in early times.
I soon was in for my third service, and as the demo dealership vehicle was missing a farmer with beat-up old Landrover was there asking for a demo, getting angry made to wait. I offered to drive him round the demo I had . One part needing an access key for a paddock gate. Anyhow with farmer in the passenger seat and one of his teen sons in the rear tray did all the usual slow low gear speeds allowing walking along beside the vehicle idling along over rough power fields even walking around the vehicle rolling along, then the steep water channel embankment up/down, stop in mid slope, keep going up forward and even stop in descent and restart reversing to top. The farmer very impressed as he realised by many years of Landrover driving that would neither manage that slope nor stop and continue from stop on that slope. On the big paddock I dropped both wheels on one side into a muddy ditch that bogged progress right there. The farmer convinced we were permanently stuck. Well with a bit of low gear and jiggling steering I soon drove back out of the ditch. I then made a serious mistake .
In high grass area to half the side windiw height I saw some white pegs in small cleared patches. In manoeuvring around several, I failed to look forward, at farmer gesture I saw a large gaping hole, as I crashed my Suzuki across the hole. Front bumper imbedded and somewhat buckled on far side of the hole front wheels in the air and rear wheels on the near side of the hole. Climbing out I could walk to the other side of the hole. I admitted that looked dire, all this onto of some huge concrete lid apparently a huge drainage pipe had been layed across the paddock. Observing that really the vehicle was on its chassis rails and rear tyres with bumper really not supporting much we noted that lifting the front applied more pressure on rear tyres. With farmers son hanging off my rear mounted spare wheel, farmer supporting the front under the engine by the cross member behind bumper, I actually reversed off that hole.
I apologised but the farmer was elated by the vehicle. He actually signed for five Suzuki's that very day, for his three farms, and six sons. Sadly the defeat never gave me any reward only a thank you for the demo.
On first 4WD club trip I was advised it was not good for that Suzuki toy, the trip would need a "Proper" 4WD.. I went anyway and during the trip made every part without issue, even had to return down a steep climb as the trip leaders Toyota, even with 4 wheels fitted with tyre chains failed to get up after nearly half dozen attempts, we had to go on via alternative tracks. Anyhow the next club magazine featured a comedic sketch of the Suzuki with a very praising text like "Go Jimny " tearing through rough hill. The group learned respect for the vehicle. Within that first year many 4WD reviews had nothing but praise.
I had a shortvterm became 1 1/2 years working in Sydney where my employer arranged for me to contact the local Landrover owners club that also participated in search and rescue and fire fighting, several local district police were also members. My first trip I turned up to at nearly 150km from Sydney , I was told as parts of the trip were hard and that little 4WD Suzuki was fine around farms, not likely to be capable of some of the trip so advised me to wait for a easier weekend trip. Otherwise since the trip was in and out by same tracks I would have to remain at where ever I was not able to go on camp and I could return out when the group would come back by Sunday. I went for the trip and as I expected more than matched requirements. In fact there was on burned clutch and four broken Axel's for larger 4WDs mainly on Landrovers. I learned as previously seen in documentaries Landrovers regularly strip diffs and brake Axel's. I took the challenge by the club joker of driving a deep water crossing between sand/rock bars at a river bend putting water splashing over my engine hood (bonnet as we call it) and only climbing out of the deep water back onto the sand bar dug in and stopped with engine idling up out the water, exhaust bubbling. The joker then tried to show how good a Landrover would do the crossing. Well he made less than half the distance bogged in deep water stalled the engine with water at side windows and engine submerged. . Both had to b e winched out, the landrover needed complete oil change, at camp several got various repairs of broken Axel's. The burned out clutch vehicle finished the trip towed and winched.
I was challenged to see how far up a long steep hill I could go I refused as I believed the climb of over 100 yards, as quite possible, but at top were several large logs across the way that would require full reversing down.. continue next comment
i have driven a Tatra that had a 6 speed automatic... with a selective low gear for crawling.
it was an absolute beast off road but less so on the blacktop... it drive fine on tarmac but you could tell it wasn't made for it.
it was like it wanted dirt and mud... it was fully locked and even though i tried to get it stuck on sand dunes... locking the last diff and airing out all the tires and lifting the suspension to get more ground clearance and it just stopped caring what was in it's way... it just went.
Hi Ian and family. On the Australia theme, look on youtube for "Austen Tayshus - Australiana (Official Uncensored Version)". Ver 'corny' but a big hit back in the day. ;)
rock bouncing next trust me
easy to watch no running in circles where you can see them only for a few seconds :-)
these trucks are like the ones in snowrunner
Noticed ur Queensland hat🤨🤨😮😮Hopefully u got a nsw one too!
I do 😉
I would assume from all the people at the top the trucks are not supposed to go all the way to the top. If those ruts get much deeper they will start bottoming out. Makes me wonder if a tank would make it to the top.
That truck has planetary gearsets on the hubs
@IWrocker In Europe you will not find any gas trucks, they are exept very very old trucks diesel engines.
I think the Unimogs have a 4 speed gearbox that splits to high between 4th and 5th (automatically), so it acts like an 8 speed.
And with the optional anf often fitted additional splitter box creates a 16 speed truck that supposedly at maximum revs in 1st gear is moving at less than walking pace.
Watch some truck trials to see what these things can really do.
You should see the crazy stuff in the oilfeilds
Giant oilfield trucks like MOL F7066 and the mercedes Z80 with 68 inch tires hauling a oilrig that has tires that are almost 200 inches
Never seen a oil rig on wheels get pulled?
Haven't seen a Praha v3s there
Try looking at Alvis Stalwart ,uk Army flying into water and swimming.
That 8 wheeler looks like a mobile crane platform
JEEP = Just Empty Every Pocket...
We call them the "Tesla-compensators"
You should check out Australian winch truck challenges.
A bit different league but search for Rába-Steiger
That tractor can pull together the sidew of the grand canyon and stitch it up
Very good video!!! nice !!!!
Like my parents steep street in new Zealand , most cars will struggle in first gear ... I tried my dads pick up truck second gear it struggled
Consider those Tatra trucks are mostly '70s models...
You still need to check out Truck Trialing,rhey use 6x6 and 8x8 trucks like you see here.
Seen icelandic hillclimb competitions?
Check out The Croatia trophy.....its one of the heaviest 4x4 event in Europe 👍
Well there's some wrong information here in the comments....Tatra is company in the czech republic thats correct but the design from the " backbone with independent swing axles" commes from the Austrian designer Hans Ledwinka who worked for Tatra . Now this guy is also responsible for the design where Ferdinand Porsche got his idea from to build the vw beetle...so without Hans Ledwinka there would be no vw beetle. His son Erich Ledwinka worked at SDP ( STEYR DAIMLER PUCH) in Graz Austria where he designed the Steyr-Puch-Haflinger and the steyr puch pinzgauer...bouth with the simmelar backbone independent axle system he took over from his father.
I wonder if they can use chains on their tyres
Reminds me of tractor pulling.
Praga V3S best offroad truck
I think it's one and done you cannot stop and start and then they record the distance and the furthest wins
If you want to try some of these trucks out check out snow runner don't do the mods it's not as fun as using the trucks they give you I enjoy it very much then watching these videos gives me more ideas for stuff to put my tatra through
American Rock Bouncers are ridiculous, check them out .
I’ll need to soon 👍😎
Basicly all truck over 5t gvw have air break Systems in europ
Look at the new Škoda concept!!!!!!!!!!!!
Mohelnice is in Czeach republic and Tatra,Praga are czeach brands
this is good video
Just noticed u changed the title, maybe change it to 'TOP Extreme Trucks Hill CLIMB Race' I think that will attract lots more people and people will be able to fully see the title
Rock bouncers are even cooler
Czech Republic
please look at OKA a western australian company I wish I could afford one
NASCAR Fan Reacts & says:
YOU MEAN VEHICLES CAN DO MORE THAN JUST TURNING LEFT??
Hey Ian, the reason you couldn't compare your truck with these is because it's a Ute... 😉 Might be a big Ute, but it's a a Ute. 🖖🏻
Hehe when talking about these huge trucks… I actually agree with you 🤣🤣 mine is a Ute 😅
@@IWrocker had to have a little dig. Here's another awesome truck with an Aussie twist. Also has a great engine sound for your sub-series. Hopefully a video on it, but if not enjoy it for yourself at least. 😊 ruclips.net/video/kJaSD6TO_WU/видео.html
i think you would enjoy formula offroad if you havent heard of it yet
NASCAR !!! How can you be a fan of cars driving round and round in a circle !!!!! I don’t understand .
Oval, and Nascar has regular tracks as well.
I prefer street racing myself but nascar is actually pretty epic. Right on the limit of grip, inches apart, 200mph. The crashes are wild too
Lol
It’s more than a circle, it’s intense racing and they do other tracks as well. But I tell ya I’m really enjoying seeing more Motorsport from around the world, it’s a nice departure from NASCAR which I’ve seen way to much of lmao 🤣
tatra has had wheels in V since production and this track is the worst in the whole season and it is actually an old quarry where moto cross and truck trial are raced 🇨🇿
I highly recommend checking out tank biathlon if you have ever wondered what racing army tanks would look like watch it and you’ll get your answer.
Trust me you’ll be impressed.
Good suggestion!
The problem with you US citizens is that you call a pickup a "truck". No wonder you realise how small your pickups are when you see a real truck.
These are definitely trucks I agree with you, but I don’t have a problem with different trucks small and big
You know "Formula Offroad" ?
Watch Bike Hill climb Andler. It's very crazy
Dude love the content...please check out dutch tractor pulling
Put a link up
power is nothing without traction.
Can we get a reaction for "C'était un Rendez vous 1976", it's more like a movie but you'll like it, you can find it on youtube.
stopping, reversing, touching a pole ...all means points down.
oh hell its hillclimb not trucktrial :D:D:D
Check out the Pinzgauer
I drove Tatra T815 8x8 at Finnish army and it was cool machines 😎
That what i drive was equipped with 19-litre twin-turbo V12 air-cooled diesel, what a sound it made...
There was also V8 and V10 engines debending your power needs.
Transmission was 5-speed with splitter = 10-speed.
It had also "off-road transfer case", so total 20-speeds.
(10 road-speeds and 10 off road speeds)
It was also syncro-box (not 1st gear) , so easy shifting up and down.
Those Tatras have quite unique central tubular frame, each wheel have their own springs and driveshafts.
Watch this:

You should try formula offroad. that is realy inzane
I believe I just featured that a month ago or so 😎🎉
Naaa... I don't think any of those are driving manual gear box, mostly automatic. It's extremly hard to drive manual in this rough terrain.
well from exerience (I have been in similar ofroad races in the car with one of my friends who is a driver) in these terrain races they drive manual. Automatic is not good for these races because youi loose one of the way to controll the car better (which is what you really need in terrain that is this complicated-also it is much easier to mantain and it lasts longer and there are less problems)
