This bus is probably a extreme survivor! I hope the owner will read this. Shown here is coach 349# it is a Canadian hound and it ran up here between 1970 to 1980. It was in a batch of 15 336# to 350#. 344# to 350# ran the Calgary Vancouver run all its life. How do I know this? I grew up in downtown Calgary back in the 70s . One block away from the Greyhound bus depot. And 2 blocks away from the Garage. My First memory of riding a highway coach was back in 1972. It was coach 347# I was 11 years old and we went on a trip to Vancouver. I was fascinated by the bus. We came back to Calgary on 348!. In any case It was a awesome bus with the V12 talk about a roar from that V 12. Through out the 70s the MC6s always ROARED and literally RUMBLED by our house over to the depot. (that is because at 12ft 6in it was too tall to go underneath the centre street bridge.) I was sad to see them go in 1980. Been retired and sold . 336# to 350# was of only 15 Canadian 6s that retained the V12 The U.S units were converted to 8V71s with automatics . That is out of 100 units built. So in my estimation it probably is the RAREST bus that I know of that is original to a degree. Seeing the Video sure brought back a lot of good childhood memories . As a joke a bus friend once said if I had a few hundred thousand spare cash lying around I could have a nice RESTORED Canadian MC6! LOL!!!! I do not know if there are any more survivng Canadian 6s. So please do not ever scrap it later on in life, send it back home up here to Canada! LOL!!!!
He just got back to me and he’s on his way here now!! Maybe we can get a ride ;)
have you ever seen an RV conversion of MC-6 that retained the 12v71?...a tour and ride video of this would be cool...interesting channel btw, good job.
Find out if he has plans to convert or restore,sale? Might be intrested if sale is in it's future. Thanks...
This bus should be kept seated. A rare piece of transportation history. MCI, then owned by Greyhound Lines, was charged with the task of replacing the aging Scenicruiser fleet. The MCI-6 was named Supercruiser, which it lived up to the name. There were 102 produced, all with 12V-71 power and the spicer manual four speed box. It was the first 102" inch wide coach, 47 passenger, tri floor interior elevation. Other features a full floating style sunvisor, flush marker lights, HUGE baggage bins for freight, apu hook up to run A/C at major terminals, the list goes on. Many considered the design ugly, I have always admired the dominate look . The coach was literally twenty years ahead of its time, which was unfortunately true to it's ultimate demise. Greyhound Lines never was able to get legislation passed to allow travel in the 48 states because of the 102" width. They initially ran on the east coast corridor, no local service. Later fifteen were sent to Greyhound Canada with the original 12V-71 and manual remaining. Others were sent to the west coast after being converted to 8V-71 and Allison automatics. Most served local Southern California , some had fare boxes installed. They did serve north into Oregon but what I have learned from retired drivers, did not enter Washington State. The MCI-7, which was introduced before the 6, became the mainstay successor for Greyhound Lines. Amazing to see one in this condition. Thank you Scott for showing us. Wish it was for sale.
The closest I ever had the chance to see one of these busses was a dark, Polaroid picture taken inside the bus garage where I worked in the late 80's. No longer in revenue service, had been converted to a motorhome, the V-12 intact, even had the tag axle covers. Thanks for your detailed knowledge of this rare piece of bus history.
Thanks for adding that. I wonder what they cost in the year they were introduced.
My dad was an MC-6 pilot out of Vancouver and Cache Creek BC.. trip10 out and trip 5 in were his regulars.. he certainly would have driven this beauty .. he was part of the convoy taking them south out of Vancouver after they were sold.. The side panels were bare grey but they still had the roof stripes.. I can’t find the pictures of the convoy staging at the garage in Vancouver and another taken from an overpass .. the drivers were not happy to see them go, but the MC-7’s and 8’s were starting to stack up..
My dad loved the MC-6, tons of torquey power by the looks and sounds of it ..
The 7 with the 4 sp was more economical, and fuel prices were out of control about that time. However the 72 and later 7s came with Allison's, which adversely affected efficiency. The 6s with the 8Vs and Allisons were slugs.

When I worked at Greyhound in the early 70's in Calgary we did a tune up, injectors etc at around 300,000 miles or so and between 6 or 700,000 miles we would do the engine. We would rebuild a complete bus engine, transmission, brakes, steering, body and interior in a day with 6 mechanics and the body interior people! Oh also interesting was in the winter if there was no room in the shop the buses outside ran 24 hours a day on high idle and had soluble oil and water in the cooling instead of antifreeze!
That's the baddest looking bus ever! so much styling all over it!!!
Thanks for the feature on the MC6 i agree wth you on the looks of them the one you showed would be a awesome conversion
Great looking bus. Something of a teaser video eh ? I look forward to seeing a little more of it in the future.
I’d love to have this!!!! 12v71 is music to my ears.
What a cool bus. It even has my home town, Sault Ste Marie in the billboard. I would love to see more of this bus. Keep up the great work. Love your videos.
The feature on that bus that interests me the most is how the fender over the tag axle is lower then the others. It looks strange but I like it.
Before the MCI 102 series this was the first of the 102 inch wide body buses between 1969 - 70 and Greyhound lines inc were the only one who had those buses in America and Canada
The buzzin' dozen. Wow, rare for sure
All 6's had 12V71's with Spicer 4 spd from the factory! 100 were made. They were all stationed on the east coast initially. Near the end of their careers, 12 were sent to Canada, retaining the 12V71 manual trans. configuration. The rest were sent to the West coast and retrofitted with 8V71's and Allison automatic transmissions. I rode them frequently traveling with my family between Philadelphia and Washington DC. The sound of that engine going through the gears and the sheer majesty of that bus has stayed with me all these years! What wonderful piece of machinery! This is when buses were designed with style!
I knew someone would know the exact details
East AND west coast. The 6s held down the LA-SF expresses and limiteds on US 101 from '68 until they were retired...the only stretch of highway where the state would allow 102" width at that time. The 4107s and 4501s held down the coast locals.. The 6 proved to the CHP that 102" width buses could coexist with trucks on the road, and paved the way for lifting the 96" limit. 102" width had been running in transit service since 1946 for Pacific Electric, but were banned on the highways except for limited "Freeway Flyers" on the Hollywood Freeway, where their slush box V-Drives and wimpy 2 valve 6-71s banned them any further north than Highland Ave.
DeserT BoB You answered my question. I was thinking I read somewhere that the MC6 was a 102” coach, but I couldn’t remember for sure.
@@dttprice GM, Twin Coach and Flxible had 102" transits dating back to the later '40s...but they were banned on highways due to the 96" width restriction. Note that early 102" wide transits were bereft of ICC ID cluster lights....that's because they weren't allowed on Federally funded highways until the 1970s.
15 went to Canada right from the factory. They did retain their 12V71's through their life.
what a great looking bus
Dalton Bus Service in Cookeville TN is where there are a bunch of these buses. They have been sitting there for several years so don't know what kind of shape they are in now.
A long time ago in the early 90's I ran into one in Vegas. A fella was living in it and he built prosthetic dental devices for Vets and others with missing facial parts out of his little shop in the bus. Interesting lifestyle I thought.
I have to agree, very nice looking bus.
I’ve seen others similar to this one with vista roofs (the windows in the roof ) very cool bus indeed .
Damn, I dig that bus!
Now this IS a BUS!
Drove one once. V8 with automatic. Nice bus. Interesting driving through the narrow metal bridge on old 58 north of the Barstow depot.
Ha! That one was interesting enough to go through in a 4107!
I wish we had these babies here in Australia
I agree, they have a very distinct look sort of mean racer shape, just a all around bold look. Cheers !
1armedguy I liken their appearance in football analogies. The SuperCruisers look like linebackers whereas the Scenicruisers are more like wide receivers
Im old as dirt & i've never seen this before, very rare indeed
my church used to have a 1972 mci mc-7 with a Spicer 4 speed, and with an 8v71. I don't know where they sent it off to, but i hope it was going to be restored or repaired by its next owner. That bus had over 2.5 million miles on it, and was still running strong
12v71 should push that bus down the road with ease lol
It would. I used to marvel at them keeping pace with cars in the fast lane on US 101 going up Cuesta Grade from San Luis Obispo before finally dropping down to third to stay at around 50. A GM 4905 would be grinding along in second at around 25 by then. The MC-7s were somewhat better than that. When the US 6s were converted to 8Vs with Allisons, they got pretty pokey.
love to see a video on how to replace a section of the exterior siding.....:)
i worked for a towing contracter for greyhound out of the d.c. garage and they all came thru with 12v71s and the with 8v71s and allisons's were convereted later.after they were built they were not leagal on most roads because they are 8'6'' wide and at the time u had to have a permit over 8'feet wide . greyhound had a permit for them for the DC to NYC they also tried a mc 7 with a Allison turbine engine with a Allison trans.it worked great but used twice the fuel as a 8v71so they only lasted about a year
There were 100 produced. 85 went to the US division, 15 to Canada for Greyhound. They came with V-12 engines. The US fleet was retrofitted with V-8s around 1977. The US fleet was sold off by 1980. They were proprietary coaches for Greyhound just the Scenicruisers they were intended to replace as flagships. Congress would not approve their 102-inch width so they were relegated to defined routes in the Northeast and the West Coast. They were 12-foot tall beasts that originally went into service between 1968 and 1970.
12V71 Jimmy is a Hoss! She'll haul ass and roll the coal if tuned right
I watched a video on these they were all but one experimental had 12v71 both in Canada and US and late in life when wornout they were retrofitted with 8V71Ts with Allisons
BGM The destination is interesting because Sault Ste Marie is on Upper Michigan's East Coast where the Sault Locks help navigate boat traffic in the Great Lakes. On the other side of the Lock is Canada, which make sense with this bus being a V-12.
Born and raised in the Canadian Soo.
The MC6 used to ply US 101 between LA and SF for Pacific Hound for many a year...the only stretch of highway where 102" width buses were allowed in CA without wide load permits. It was quite a sound to hear one downshift from direct to third to take Cuesta Grade up in San Luis Obispo...these buses meant business on a hill. PGL swapped out the 12Vs for the standard 8V and Allison sometime in the early '70s for two reasons....fuel economy, and Hound was going all automatics from the 1972 batch of MC7s onward. Expect around 5 MPG with the 12V...if that. They drive like an MC7...sloppy Ross steering and all...and didn't ride as well as the 4501s.
Ouch that's awful. No wonder they quit making them. But the sound is soooo awesome!
DeserT BoB I was told before the criss-country trek that I should expect 3-5 MPG (by people who guessed by extrapolating from their 6 or 8v71 experiences. I got 5 3/4 mpg through the Rockies and 6 1/4 on flatter terrain cruising at 75 mph. I get 6 1/2 mpg if I keep it at 65-70 mph.
@@photonole61 You also didn't have a load on! Stick 47 pax and their baggage and have the rear bay crammed to the gunwales with package express, 5 was about it...but it could still take a grade like no other! The 8V conversions were slugs that a 4104 with a 4 valve head could pass with ease on a hill.
They were all 12V71 from the factory. The US 'Hound converted theirs to 8V71's and Allison automatics. Only ran on odd runs because they couldn't get the permits for the 102" width. Canadian 'Hound didn't have those issues. Theirs stayed 12V71 and manual trans.
BGM...the blunt BLOCKY looking "checker taxi cab" front bumper caught my eye and would help to keep moose deer and other large critters (pedestrians) out from the undercarriage...V12 would have definitely gave her some ZIP...
Ours were 12v71's and manual transmission in Canada!
Cool!
Bus TV Chan has a video same bus very nice bus :)
I have mc6 in my backyard rhd Australia one long way home 12v71 use did Alice Spring run plus Canadian Build ship to Melbourne
With a Sault Ste. Marie destination roll,yep,a Canadian bus all right. Was Florida a part of the Louisiana Purchase ? Certainly in the right geographic part of the 48 States,at any rate. Hopefully giving some Cajuns a warm feeling when they see it.
the buzzin dozen
FYI: Allstate Charter up in Fresno had a V12 MC6 in charter service for years, as well as the low mileage MC7s I used to drive for a private operation. Last I heard, it was still showing up as Pacific Bus Society events out here. It was one of the VERY few that went to secondary ownership with the V12. Charter operators didn't want them primarily due to really bad fuel economy...although it wasn't quite as bad as a Brill IC41 with the Hsll-Scott 190! Those Trailways turkeys were good for 2 MPG, and had no brakes...but they'd run 85 MPH!
Great vid! There is an orginal V-12 bus up here on Vancouver Island ...now repowered with a 8-71
I’ve got an MC3 that is a hoot to tool down the trail with. But if I ever find the folks who did the RV conversion, I’m sorely tempted to beat them with all the terrible terrible wiring hacks they did to the poor girl. Completely co-opted the 12V system for their own use, and wired all the stock systems to the 24v. And for a capper, installed the 12 power supply, and the 110v breaker panel *under the kitchen sink*...
Greyhound was the only company who had The MCI MC6 it's 102 inch wide Canada had those with the 12V71 with the 4speed manual and American they had to Switch Drivetrains on all of them buses they had 8V71 N Detroit Diesel engines with HT740 Allison Transmissions in 1977 that's a rare Coaches
👌👌
Can you tell me how durable the 2 stroke Detroit is? What is the time between pistons and liners and blowers? I love the videos. Keep them coming.
Never heard the sound of a 12v71. I like the sound of the 6-71TA in my Crown.
here's a good video....
ruclips.net/video/ZmytwZnXgjM/видео.html
not a bus, but he drives it like he stole it later in the video haha...not called the buzzin-dozen for nothin :D
Here is one with the bus and engine in question actually operating. The V-12 was probably overkill, but I can see where the company was heading trying to prove the MC-6 was a force to the future. ruclips.net/video/-YFNqyvkMi8/видео.html
WOW! 12 V !!!!
what was the MCI bus that has the deadly massive belt in the rear with air tentioners with side top radiators?
Only 102 of the MC-6 were made. They were all originally built with the 12V71 engine and manual transmission, but the US units were rebuilt in 1977 with an 8V71 and Allison automatic transmission. I think there was a prototype that had originally two smaller engines & they wound up putting the 12V in there?
2005dave the 2 4v71’s were in the PD 4501 Scenicruises initially. The SuperCruisers all started with the 12v’s
A general question, do drivers need a specific driving license to operate one of those buses in the US?
In Australia even as a non passenger carrying mobile home we have to do a commercial driving course and have our license uprated, for a bus the size shown probable a HR class, being heavy truck, rigid (non articulated) Our licenses are graded mainly on GVM or GCM (Gross Vehicle Mass for rigids or Gross Combination Mass for articulated)
Every state is different. I've had 4 busses from a 60 Chevy short bus 50 series with a Dodge 383 and Torqueflight to '47 REO with a White Mustang rear motor 3-speed on floor to a 38 ft. Bluebird with a Cummins V-8 in front with a 4-speed Allison auto to a '75 Flxible city bus with a 6v-71 Detroit diesel with a 2-speed hydraulic transmission. In the state of Kansas you can drive one without a CDL. But I've been a truck driver all my life and have had a CDL since before they had CDLs. Class A back then. A lot of states do require one, though.
Buy glass insurance, and see insurance company cry)
maybe it was willie nelsons ? He has an album cover of being in one
this is ex greyhound canada #349!
Great find. I never knew, or even suspected they put the V12 in a buss. Did this application use twin turbochargers ?
I don’t believe any of them originally had turbos
Clockwise
Scott Hanson.... No, all of them were NA with two roots blowers (positive displacement) for scavenging, as do all 2 cycle Detroits.. turbocharged or not... even the series 51 engines, which were loop scavenged and valveless.
I'm questioning if this bus has the 12V-71 since the exhaust is not coming out the left side of the bumper. When converted to 8V-71, the exhaust was rerouted elsewhere and a plate was put over the left side of the bumper covering the louvers of the 12V-71 exhaust.
It’s a 12v Watch the next video
Yep 12V-71. But too bad it doesn't have the original bumper exhaust-it was really cool.
It has the factory exhaust below driver side rear. It never went through the bumper (none of the 6’s). The rear bumper folds down revealing the accessory drive belt.
You must not have been around when the first 6's came out because I distinctly remember the exhaust coming out the left side of the bumper. You'll notice most have a plate riveted to the side where the exhaust used to come out.
What does the MCI stand for?
Motor coach industries
100 made.
I would do a little better on the body of the MCI MC6 like the roofline keep it even the Rear deck lid and the fenders and the windows if I'm was designer of this model they were built between 1969 - 70 the rest of it leave it alone but it's MCI who built this bus
101 made
