My grandfather used to race a post WWII German 2 stroke, a DKW in hillclimbs. In the days where the only requirement was engine displacement. He mopped up all the 4 strokes, having twice the powered cycles per revolution.
Yes, that last footage of the subsonic from the interior is actually a Saab Sonic V4 which was not a two-stroke that's evident by the hump on the hood unless somebody put the later hood on the earlier two-stroke car
Hey Rick! I agree. They are magic. I had no idea how crazy they were until I started seeing videos on them. 2 stroke diesels rule the sea. 2 stroke engines with blowers instead of crankcase pumping are perfect for hybrid cars. I wonder if they have been passed over by the powers that be. Truly remarkable little beasts. Ha!
I'm inspired to take my 1980 Suzuki RM100 out of the barn and ride it! I remember, after the Berlin Wall came down, pulling up to a traffic light in Berlin and hearing a bass boat pull up along side me. I looked over, and it wasn't a bass boat. ...It was a Trabant!
It would sound totally different if it were super charged with a controlled exhaust valve. You wouldn't get backflow from the exhaust and the ring a ding ding sound... otherwise no one would go to watch f1
not really, a wankel rotary works on a 4stroke cycle, but due to its design, it does have twice the amount of combustions per revolution of the eccentric shaft than a four stroke, just like a 2stroke. the fact a wankel doesn't have valves but just intake and exhaustst ports like a 2stroke petrol engine, also contributes to the sound :)
yeah no kidding. The 2 stroke is all about flow dynamics. Rotary engines are based on similar principles but rely less on how it flows. rotaries are essentially rotating 2 strokes but have a more consistent idle because of their more predictable pumping methods.
Wankel rotary, or Le Rhone rotary? The Le Rhone was a "radial-ish" design, where the crank was bolted to the firewall, and the whole engine spun around, and the propeller was connected to it. ( My 10th grade metal shop teacher, made replacement carburetors, for this engine, that is how I know all this trivia. Oh, that class was in 1974.) en.wikipedia.org/wiki/Le_Rh%C3%B4ne I'm quite sure you mean the Wankel (Mazda) engine. (Yes, quite a few people used the Wankel design, including the model engine maker, OS Max.) Like others have pointed out,that sound comes from the exhaust port, opening almost instantaneously. (Just like a 2 stroke.) steve
Man i miss 2 strokes. I remember back in my younger days they were everywhere... But now thier few and far between. We would always used castor oil and i loved that sweet smelling exhaust, Reminds me of track day!
My favorite thing about castor oil being that it's bean based, is that it kinda smells like French fry oil when it burns. Reminds me of the exhaust vents around fast food joints.
Those Berkeleys look like fun. I worked for several years in a quarry. Part of the mobile plant fleet was a Wright grader, powered by a two-stroke diesel engine. Every evening at 17:00 it would come past my office - I had to make sure I wasn't on the telephone at that time!
What a pity that it was only the last ar that was really revved out. I love the sound of a hard revved two stroke, music to my ears. Also good to see that two strokes are making a comeback amongst the off road bikes, wish they would bring them back in large displacement road bikes.
Are they? Yamaha's 4 stroke makes the same power now as a similar sized 2 stroke. Also race leagues are almost all using 4 strokes AFAIK. There are a few guys using 2 stroke but its all but gone.
@@congerthomas1812 Im sorry but they make a little more power while being a pain to refuel and are wayyy, wayyy dirtier. I just don't see them making a comeback lol. Especially when electric is coming up so fast.
Awesome two stroke cars. The awesome two stroke in all its glory. I love them. That's probably why I have been bisecting and examining theses types of engine for the last 25 years. Thanks for sharing this video! Craig
I love the exhaust setup on the race car. I thank you for showing me car that I haven't actually seen before, where most say that and show you stuff that's the same as a million other vids
Got to love the last one, winding out a 2 stroke and banging gears with a column shifter! Don’t see that every day! Great channel by the way. Never would of known about so many odd ball cars if not for you!
There are major differences between a "2-stroke motor" and a "horizontally-opposed piston motor", which is what this truck has. Also, it's not a "car", nor has this type motor ever been used in a car. These type motors were used in Fairbanks-Morse locomotives, and were also very common in large ship motors.
I remember a car that raced at Santa Barbara Airport when they raced there back in the 1960s. It was powered by 2 100hp mercury outboard engines converted to drive the car. When he punched the throttle to accelerate down the long straight it sounded like an explosion. He passed a lot of cars right up till one of the chains driving the rear wheels broke and he went round and round before he could get it stopped.
If I recall correctly, the tiny engine in the Berkeley T60 can also run backwards, thus giving it as many reverse gears as forward gears. If not that, then there is another small three-wheeled sportscar from England with such an engine.
5 лет назад
I have a feeling the Invacar from the 60s could do that as well!
My friends mother had a Saab don't remember the model. But when you fuel it up the gas cap was also the measuring cup for the oil. She was a big lady & we used to get a kick when she would rock the car back & forth every morning to make sure the oil was mixed before starting the car.
I saw one of these Suzkis on Grenada during the intervention. One had bullet hole through the windshield where the driver would be sitting IF it wasn't right-hand drive. I can imagine the shock of the sniper when he thought he put a round dead center of the driver and it kept right on going!
It's wild how 2 strokes are very powerful for their weight at small cc's (65cc to say 500cc) but after that seems 4 stroke takes the lead by far.... Nowadays we got 2.0L hondas pushing nearly 1500hp. Crazy
thomas barlow indeed. 4 stroke engines have worse power to weight ratios. But they are more efficient. 2 strokes are much less efficient but have much better power to weight ratios. However I've heard somewhere that two stroke engines can be more efficient if given crossheads. Some of the most powerful and efficient engines in the world are two stroke crosshead low speed diesel engines. The most powerful being about 109,000 horsepower and torque that is enough to shake the damn earth. Lol. A little over 1.5 million foot pounds of torque with efficiency approaching 60%. I wonder what a Gasoline engine of equivalent size would be like. Lol.
2 strokes still produce more power today than 4 strokes. Check out the Suter V4 500cc sport bike. It's 500CC V4 engine making 240 hp. Compare that to a liter bike, if you doubled the 2 stroke displacement that would be 480 HP whereas todays highest horsepower 1 liter sport bikes make about 170-200 HP. And that's with limited 2 stroke R/D because no one is putting money into 2 stroke technology anymore.
i have cilynder on bike that have bigger intake than exhaust that thing have so much torque that can start in 3rd gear with litlle rpm but it cant rev over 5000rpm with right exhaust its like tractor
2 stroke motors would be successful in cars with a few additions.. 1) Crank case oiling. Since 2 strokes rely on oiling from the fuel mix, when off throttle the engine can be damaged and actually overheat without throttle. The crank would need its own oil basin like 4 strokes.. 2) Valves. Crankshaft-timed valves for the intake and exhaust would allow for supercharging and possibly turbocharging 3) If the crank case was oiled with a basin, you would need much leaner of a gas/oil ratio... leading to a more efficient burn.
Thank you VisioRacer, I had no idea that Bigglewade had any kind of car industry. Its something we can be proud of locally (apart from our ability to grow brussels sprouts)
I am about to test run my own two-stroke automotive engine design (see my avatar). Supercharged and turbocharged for high specific output and GDI for low emissions too.
Two cycle engines with intake boost ports make boost as you hear it hit the power band "on the pipe" that is when a two cycle self supercharges making boost and its not back pressure of exhaust gasses that stops the boost from blowing out the exhaust port its the sound waves reflecting off the reverse cone of the expansion chamber that hit the opening right where the pipe attached to the exhaust port and makes an invisible barrier holding back bars of atmospheric pressure that never stops building as the cfm of the carb or throttle body is the only limiting factor .this is why a naturally aspirated 4 cycle engine will never have the same horsepower as a two-cycle engine same size cause two cycle engines with boost ports boost
bobfather The reality is a 2 stroke can actually get better emissions because it recycles a portion of its exhaust many 2t motors have 2 timing marks and are ignited at top to induce the power stroke and again on the tail end to burn un-ignited fuel fuel. Here’s an interesting motor originally designed for the military but after taking it from DARPA theory to prototype the military deemed it not usable for what ever reason and didn’t hold the patent so it’s now on the civilian market. thekneeslider.com/ecomotors-opoc-two-stroke-engines-opposed-piston-opposed-cylinder/
@@entropicgirl8648 no, thats not true. Yeah, they recycle a portion of their exhaust but the power stroke occurs every 2 strokes. The power stroke in a four stroke engine occurs every 4 strokes. This makes 4 stroke engines more environment friendly

5900?? Dang that's high for a diesel! Still though, I'd love to see a lowest-revving petrol compilation, I mean not ancient 1930s engines but recent ones. Because we once took a rental 1.2 Micra, not sure if the thing was limited or not but it would not rev past 5500 which is ridiculous for a petrol haha
Thanks for another awesome video Visio and happy Xmas! Idea pitch for another video: "Highest revving Diesel engines" (Drag racing or pulling got to 6k and the Audi LM ones revved pretty high too, so pretty interested in that)
I grew up on two stroke motorcycles , the peak of technology was the 1991 Honda NSR500 , 200bhp 320kmh the Honda engines offered more power but the tyre and chassis tech could not cope Today's MotoGP bikes give 300bhp from 999cc I'm sure two stokes could beat that with today's tech I would love to build a Cateram super 7 with an Evenrude 3.5V8 two stroke
Though i am biggest romeo of 2Stroke motors, so i was a fan of Saab from long time but when i saw whole video and got to know about ""Commor TS3"", i said to myself i got another 2 stroke to date with!!
what i like abaut 2 stroke is that with a couple thousands euro you can get a motorcyle that goes faster than most supercar, revvs higher and sounds waay better
There were various small 2-stroke cars built here in Australia in the 50's & early 60's in small numbers, with Buckle Motors' Goggomobil Dart being my favorite design (although it's probably the best known) of which 700 were built!
This presenter is very knowledgeable and my only criticism is it when introducing a car the stats are not held up long enough on the screen for you to read them properly give it another few seconds please.
That 6-cylinder race car and the Commer was very interesting! About the DKW F102, I believe it was actually only produced 1964-66. VW bought Auto Union and revieved the Audi name. The four rings is not originally Audi, but Auto Union, and they stand for the four brands Audi, Horch, DKW and Wanderer. It's funny to see under the hood of much more recent Audi and see the engine in the same position still as in the F102/3 - fully in front of the (imaginary) front axle. :)
The assumption seems to be that an F1 2 stroke will be a small capacity engine because that has been the history of 2 strokes in the automotive industry. A better idea of the possibilities would be to look at marine 2 strokes. Over 40 years ago Outboard Marine Corporation (OMC) produced Evinrude and Johnson 3.5 litre 2 strokes for racing in F1 powerboat racing. Mercury responded with a 3.4 litre V6. These engines produced north of 500 hp and made a sound that makes a V10 4 stroke sound sickly. I can't even imagine what sort of output could be obtained from modern versions of these engines using current technology, metallurgy and engineering.
Some people who don't know cars say they are bad, but as someone who understands cars very well, I can claim that they are great cars. They were really high quality and character cars.
Only had one crankshaft, 6 pistons, 6 rocker arms, 12 connecting rods, 2 rocker shafts, worked on them 50 years ago, but still remember them like yesterday.
There was a 700cc fuel injected Goliath in a wrecking yard in Madera CA. Had a sunroof and I'm sure Porsche used the same one. I carried a set of 3 carbs for a c1960 Saab. Couldn't give them away so after 30 years I left them in a barn in 2000.
2 strokes are the most efficent engines in the world. The largest 2 stroke diesel crosshead engines have 100,000 horse power and 5 million foot lbs of torque. 22-120 rpm. The piston moves 8 feet up and then 8 feet down, and it's nearly 3 stories tall. The engine exceeds 50% thermal efficiency, a chainsaw engine is less than 20%
love the Sonnet III,, even the v4 was a revver with no torque. you had to keep your foot in the carb to get down the road from a stop. very sporty feel tho! thanks for a great vid!
At 4:55 you say that the DKW F102 is one of the last cars with 3 cylinder 2 stroke engines yet they stopped making it in 1969. The Wartburg knight was built through the '70's and had a 1 litre 3 cylinder 2 stroke engine.
A sigla DKW significava inicialmente "Dampf-Kraft-Wagen", carro de força a vapor, já que os primeiros produtos oferecidos pela empresa foram pequenos motores a vapor.
A DKW é uma marca histórica de automóveis e de motocicletas, associada em todo o mundo a motores com ciclo de dois tempos, que teve seus automóveis fabricados sob licença no Brasil pela Vemag entre 1956 e 1967. Aqui, a marca ficou conhecida popularmente como “DKV”. A DKW foi uma fábrica alemã fundada em 1916 pelo engenheiro dinamarquês Jørgen Skafte Rasmussen que, em 1932, com a Grande Depressão, se uniu por sugestão do Saxon National Bank a outras três fábricas, a Audi, a Horch e a Wanderer, para formar a Auto Union. Em 1938, o grupo ganhou a participação da NSU. Em 1957 a Auto Union foi adquirida pela Daimler-Benz e, em 1964, pela Volkswagen, passando então a ser denominada Audi.
Very interesting video.. id like to know more about those cars.. also congratulations on your channel, im an old viewer, i end up liking most of them, regards from Brazil.
DKW, Wartburg (IFA) and Saab two-stroke engines are strongly related. The Wartburg cars were developed from a DKW car. Saab baught technology from IFA to safe time of development.
and he totally ignores it .. to mention DKW F102 as one of the last 3cylinder two stroke cars is not correct - as the whole Wartburg model range was produced way longer in the other half of Germany .. and we had not only the Wartburg cars .. Barkas and Trabant was there as well
I read somewhere that when the DKW factory was being decommissioned, somebody found a Scott 2 stroke motorcycle engine, which has many similar design to the first 2 cylinder 2 stroke DKW
That Koehler powered car races in P1, Formula C is an open wheeled class with a spec engine. Interestingly this category currently allows two spec engines, they’re transitioning to a Honda engine, the old engine is more interesting as it’s a Ford Pinto engine using leaded gasoline.
My grandfather used to race a post WWII German 2 stroke, a DKW in hillclimbs. In the days where the only requirement was engine displacement. He mopped up all the 4 strokes, having twice the powered cycles per revolution.
The SAAB has such a lovely sound!
Lars Becker yes

Yes, that last footage of the subsonic from the interior is actually a Saab Sonic V4 which was not a two-stroke that's evident by the hump on the hood unless somebody put the later hood on the earlier two-stroke car
5:42 ..... finally someone who drives a 2 stroke the right way!
Joe Webster nope, he let clutch pedal too early. I know, it's much faster that way on video.
I meant I thought the rest were putting around until then. Very boring before that.
@@Pabcio I think the clutch is slipping
You gotta rev the heck out of a 2 stroke for it to be really fun.
a 2 stroke has to be revved higher because it has no guts at low rpm's

Hey Rick! I agree. They are magic. I had no idea how crazy they were until I started seeing videos on them. 2 stroke diesels rule the sea. 2 stroke engines with blowers instead of crankcase pumping are perfect for hybrid cars.

Idea pitch for another video: "Highest revving Diesel engines" (Drag racing or pulling got to 6k and the Audi LM ones revved pretty high too, so pretty interested in that)
I grew up on two stroke motorcycles , the peak of technology was the 1991 Honda NSR500 , 200bhp 320kmh the Honda engines offered more power but the tyre and chassis tech could not cope
Today's MotoGP bikes give 300bhp from 999cc I'm sure two stokes could beat that with today's tech
I would love to build a Cateram super 7 with an Evenrude 3.5V8 two stroke
That's crazy. 🥰🤗 As a two stroke fan in the world of dirt bikes I've never heard of two stroke cars..
Though i am biggest romeo of 2Stroke motors, so i was a fan of Saab from long time but when i saw whole video and got to know about ""Commor TS3"", i said to myself i got another 2 stroke to date with!!
what i like abaut 2 stroke is that with a couple thousands euro you can get a motorcyle that goes faster than most supercar, revvs higher and sounds waay better
There were various small 2-stroke cars built here in Australia in the 50's & early 60's in small numbers, with Buckle Motors' Goggomobil Dart being my favorite design (although it's probably the best known) of which 700 were built!
I grew up with two strokes , snowmobiles and dirtbikes
This presenter is very knowledgeable and my only criticism is it when introducing a car the stats are not held up long enough on the screen for you to read them properly give it another few seconds please.
Last one in the video is most impressive out of the street legal ones. The race car one is sick!
YEAH! I LOVE 2 STROKE VIDEOS XD
The sonet was icing on the cake.
I had no idea at all that the Jimny could be had with a 2-smoker! Now I have to have one.
They have NO flaws. - Fixed it for ya! 😁
For anyone wondering the p1 racecar is fielded by Wynnfurst racing. Driver is Jason Miller. Know them all personally
Wow, I had no idea there were so many 2-stroke cars back in the old days!
That 6-cylinder race car and the Commer was very interesting! About the DKW F102, I believe it was actually only produced 1964-66. VW bought Auto Union and revieved the Audi name. The four rings is not originally Audi, but Auto Union, and they stand for the four brands Audi, Horch, DKW and Wanderer. It's funny to see under the hood of much more recent Audi and see the engine in the same position still as in the F102/3 - fully in front of the (imaginary) front axle. :)
The Goliath is just screaming Volvo amazon to me
I always thought it was Suzuki JIMMY not JIMNY
4:16 so how many exhausts do you want again?
*yes*
best of crossplane cars.... please
I love this channel this is the best car channel in the whole universe
Put 4 Suzuki's back on the road in Australia. All they needed was rings,the heads don't come off the cylinder.
The assumption seems to be that an F1 2 stroke will be a small capacity engine because that has been the history of 2 strokes in the automotive industry. A better idea of the possibilities would be to look at marine 2 strokes. Over 40 years ago Outboard Marine Corporation (OMC) produced Evinrude and Johnson 3.5 litre 2 strokes for racing in F1 powerboat racing. Mercury responded with a 3.4 litre V6. These engines produced north of 500 hp and made a sound that makes a V10 4 stroke sound sickly. I can't even imagine what sort of output could be obtained from modern versions of these engines using current technology, metallurgy and engineering.
Well, I miss the Trabant 600, 601, the Warburg 1000, I certainly remember them.
Some people who don't know cars say they are bad, but as someone who understands cars very well, I can claim that they are great cars. They were really high quality and character cars.
The DKW3=6 sounds nice
I used to have one of those Suzuki. Mine was 2 cylinder 2cycle liquid cooled. It would jump out of mud ruts like crazy. The starter was very quiet.
i remember as a child there were guys with 2 stroke diesel machine for sawing logs....there are few left even now.happy new year
machine is band saw
51 hp! That was crazy! I could get out and push.😉👍
Always fun videos from you 👍
Hey VisioRacer,
Nice video! I love two strokes. The Commer was my favourite out of these. The Saab is a nice machine as well.
Merry Christmas 🎄
That Saab was the best sounding 2 stroke, followed by that cool old British lorry with that really odd 2 crankshaft, 3 cylinder diesel..
Only had one crankshaft, 6 pistons, 6 rocker arms, 12 connecting rods, 2 rocker shafts, worked on them 50 years ago, but still remember them like yesterday.
There was a 700cc fuel injected Goliath in a wrecking yard in Madera CA. Had a sunroof and I'm sure Porsche used the same one. I carried a set of 3 carbs for a c1960 Saab. Couldn't give them away so after 30 years I left them in a barn in 2000.
2 strokes are the most efficent engines in the world. The largest 2 stroke diesel crosshead engines have 100,000 horse power and 5 million foot lbs of torque. 22-120 rpm. The piston moves 8 feet up and then 8 feet down, and it's nearly 3 stories tall. The engine exceeds 50% thermal efficiency, a chainsaw engine is less than 20%
Two-stroke loveliness!
love the Sonnet III,, even the v4 was a revver with no torque. you had to keep your foot in the carb to get down the road from a stop. very sporty feel tho!
thanks for a great vid!
At 4:55 you say that the DKW F102 is one of the last cars with 3 cylinder 2 stroke engines yet they stopped making it in 1969. The Wartburg knight was built through the '70's and had a 1 litre 3 cylinder 2 stroke engine.
A sigla DKW significava inicialmente "Dampf-Kraft-Wagen", carro de força a vapor, já que os primeiros produtos oferecidos pela empresa foram pequenos motores a vapor.
A DKW é uma marca histórica de automóveis e de motocicletas, associada em todo o mundo a motores com ciclo de dois tempos, que teve seus automóveis fabricados sob licença no Brasil pela Vemag entre 1956 e 1967. Aqui, a marca ficou conhecida popularmente como “DKV”. A DKW foi uma fábrica alemã fundada em 1916 pelo engenheiro dinamarquês Jørgen Skafte Rasmussen que, em 1932, com a Grande Depressão, se uniu por sugestão do Saxon National Bank a outras três fábricas, a Audi, a Horch e a Wanderer, para formar a Auto Union. Em 1938, o grupo ganhou a participação da NSU. Em 1957 a Auto Union foi adquirida pela Daimler-Benz e, em 1964, pela Volkswagen, passando então a ser denominada Audi.
This list should have included the Belkus RS1000. It was a sportscar from the DDR and i believe it used a Wartburg 3cyl engine,
Lloyd Alexander also used 2 stroke as well a 4 bangers front wheel drive.
I do love the sound of my v4 outboard out of the water.
Hey Visio, i own a twin cylinder two stroke car which has been made in only two pieces in the entire world!
There is a lenghty scene involving a Commer 2 stroke truck in Hithcock's 1972 movie Frenzy. I love the howl of those trucks.
Love how the Jimmy was filmed by a asc t128
The Kohler originally started out in the D Sports Racer class in the 1980s. I saw it run at Elkart Lake in 1982.
You should check out the Junkers Jumo 205 aircraft engine. 6 cylinder, 12 piston, 2 stroke diesel. Amazing bit of engineering from the late 30's.
Very interesting video.. id like to know more about those cars.. also congratulations on your channel, im an old viewer, i end up liking most of them, regards from Brazil.
I want 2 strokes to be used in small race cars in future
Releasing on christmas nothing stops u
What about the Detroit Diesel engines?
We have a giant fork lift with s Detroit in it. Any old school mechanic or truck driver instantly knows the sound when it fires up!
DKW, Wartburg (IFA) and Saab two-stroke engines are strongly related. The Wartburg cars were developed from a DKW car. Saab baught technology from IFA to safe time of development.
and he totally ignores it .. to mention DKW F102 as one of the last 3cylinder two stroke cars is not correct - as the whole Wartburg model range was produced way longer in the other half of Germany ..
and we had not only the Wartburg cars .. Barkas and Trabant was there as well
I read somewhere that when the DKW factory was being decommissioned, somebody found a Scott 2 stroke motorcycle engine, which has many similar design to the first 2 cylinder 2 stroke DKW
That Kohler Wynfurst is driven by Jason Miller. I see it all the time at Road America in Wisconsin
Twostroke-Engines are the future.
That DKW F102 is a nice little unit
They all smoke like troopers and sound like a tin of angry bees.
wow, and the shifting on the column... too cool
That Koehler powered car races in P1, Formula C is an open wheeled class with a spec engine. Interestingly this category currently allows two spec engines, they’re transitioning to a Honda engine, the old engine is more interesting as it’s a Ford Pinto engine using leaded gasoline.
nice video
Thanks for taking the time to make the video and share it 😊
all of them sounds like a moped!! i love 2 stroke cats!
No they dont😂😂
Great you took Saab here too. 👍👍
