America's RARE Forgotten Canyon Carver - The 1975-1976 Chevrolet Cosworth Vega

👉 Become a Rare Cars Founding Member: rarecarsmedia.com/
In this Rare Cars documentary, we go in depth into the misunderstood and largely forgotten Chevrolet Cosworth Vega. This compact canyon carver was build in a very unique partnership between GM and Cosworth to create a compact sports car for Chevrolet to use to compete with the smaller more nimble European cars.
But did it succeed? Watch the video to the end to find out for your self!

EDIT: The Vega's 4 cylinder is NOT based on the QUAD 4 pictured from the Oldsmobile...It is based on the GM 4 cylinder that is also referred to as the "Durabuilt-4", the Quad 4 name came after. I must have gotten the two confused when I spoke on the video so please take the "quad four" and replace that with the 'Durabuilt-4" and all the other facts are the same. Apologies for the misspeak!

I've been mechanic for 30 years and you Still show me cars I haven't heard of. I also know that if you want to correct somebody on their own channel it should be done appropriately without public s*** talking so hopefully that was accomplished.

[@robertcabrera6232]

Glad you corrected this, as I was headed to the comments to post this. The Olds Quad 4 was a newer design from the mid '80s with an iron block and aluminum heads, that from the ground up was intended for dual overhead cams and 4 valves per cylinder. There were a few that were made with a single cam and 4 valves that were called "Quad OHC," and shoved into el cheapo econoboxes, but the vast majority were decently powered modern DOHC. The Vega engine on the other hand was a SOHC, all aluminum block casting with no cylinder sleeves and cast iron heads. They were notorious for overheating and oil consumption issues, and for eventually blowing head gaskets. This was because of several factors. GM skimped on production costs by not having steel cylinder liner sleeves, which created an issue where the pistons expanded more and faster than the cylinder bores under load. This lead to premature wear and oil burning. The same goes for the iron heads and aluminum case. The heads would expand faster, which put tremendous stress on the gaskets causing high failure rates. Once they over heated they were nearly impossible to repair as warpage was common. Additionally, the way the case was cast made it nearly impossible to bore the cylinders and deck the mating surfaces with the head, so no machine shops would touch them, making rebuilding nearly impossible. My Dad bought a used low mileage Vega, cheap, sometime around 1980, and it ran flawlessly for several years until it overheated for the first time in scorching hot Miami stop and go traffic. Then it never ran right again. He must have taken it to a dozen mechanics, but either they wouldn't work on it, or their repairs were half-assed. It wasn't long after that first time it over heated when it started burning oil like a pig, and he couldn't drive it further than 20 miles or it was sure to overheat. After a year or so of dealing with those problems he tried trading it in, but dealers wouldn't give him anything for it, even though the exterior and interior were in near showroom perfect condition. He eventually sold it to a family member that had just arrived from Cuba for a couple of hundred bucks.

[@angelperez7891]

But after the discontinuation of the Vega Cosworth Twin-Cam model the entire engine's basic design was later built in-house by Oldsmobile as the Quad 4 but larger (2.2 liters and up,) superior horsepower (as high as 200,) but no compatibility or interchangeable parts with the Cosworth-tuned Vega engine.

[@bloatedgoatfpv]

Glad you covered this. The dohc head was Cosworth's design. The quad 4 was wholly engineered in house at GM (their first) and debuted in1987 or 88.

[@andrewwasson6153]

I think the 70-73 baby Camaro Vega hatchbacks were the nicest looking Vega’s. I had one that I stuffed a Chevy 350 V8 into with a Holley 600 with vacuum secondaries and a Weiand dual plane manifold. Not a very complex power plant but it was very fast and completely dependable. The downside is that it got very rusty in the lower door skins, lower fenders and the area around the hood.

[@frestkd]

The Quad4 was designed and developed by Oldsmobile not Cosworth. GM Cosworth engine was designed before the quad4.

[@MikeBrown-ii3pt]

WAY before!

[@Paul_D_Lashley]

I was going to say the quad4 came out in the late 80’s early 90’s. They put it in the aero tech pace car for Indy. I think it was called aero tech. My dad worked for an olds caddy dealer and that aero tech was bad ass looking.

[@angelperez7891]

Oldsmobile copied the design concept for the Quad 4.

[@BuzzLOLOL]

@@angelperez7891 - Olds had W43 DOHC 4 valves per cylinder 455" V8 way back in 1968... they knew how to do such things... just the thought of it caused NASCAR to ban it...

Ford owned Cosworth at that time

[@tobization]

I had a '75 Cosworth Vega. The air injection system (the tubes you see running over the valve cover) connected directly to each header primary tube. It would suck raw gas into the tubes and pump it into the exhaust system on deceleration and blow 5 foot flames out the exhaust - at will. I yanked the fuel injection system (sold it to a collector in San Luis Obispo) and bolted on a Hutton manifold replete with Weber carburetors. The car would snap oversteer when pushed to the limit. The brakes were shit as was the shift linkage. The mid-seventies to mid-eighties were terrible for car enthusiast choices.

[@andyharman3022]

Yep, I put the HME dual Weber setup on my '75.

[@kevinhuber8723]

an honest evaluation. No matter the cylinder head, these cars were JUNK. The head became a beast in USAC Midget racing for a few years.

[@mutantryeff]

Did you know that GM special trains built so that they could stack Vegas vertically while being transported instead of horizontally like most cars? They could get more Vegas onto a single special transport train car to reduce the costs of selling the vehicles.

[@rarecars3336]

This is an awesome piece of input!

Takes me back to the days of my youth. A guy that had a gameroom in my hometown (in Texas) had one of these. Black w/ gold trim and old-school flames on the front. This was '76. It just as easily could have been parked outside The Emporium gameroom in the movie "Dazed & Confused" (which was set in '76, in Texas). It's a neat car & was an even neater time to be growing up in America.

[@Cartier_specialist]

I was fortunate enough to drive one back around 1977 and it felt stronger than 110 hp. Of course back then everything was so slow that any car capable of putting you back in the seat seemed fast. Fast forward a few more years and I had the opportunity to drive a 1979 Plymouth Fire Arrow 2.6 and it was definitely quick for its day.

[@ronalddaub9740]

I fondly remember, everyone with a Vega or Monza in high school strapped a 327 or 350 into it... fun times.

[@sombra6153]

I think the real problem was Vega motors in general had serious durability problems and I remember starting to hear about them as early as 1974 long before home computers, the Internet and social media. The good thing was it made used Vegas in need of an engine very cheap and gave birth to the “ V-8 Vega “ aftermarket phenomenon.

[@BuzzLOLOL]

Those aluminum block Vega 4s couldn't withstand the slightest overheating... plus a timing belt for the OHC meant it wouldn't be long before the engine failed from a broken timing belt... and aluminum block vs iron head had high risk of head gasket failures from different heat expansion ratios... The Pontiac Iron Duke 4 eliminated all those problems...

[@janofb]

I had 2. The block was made of an alloy that the iron rings scored, and you got massive oil burning. They should have warrantied it but didn't. Don't know why I ever bought the second one after owning the first, but I swapped an old's v6 into it and it was great.

[@edmundanderson657]

[@AB1Vampire]

A cloud smoke coming out the back of a Vega was very common to see in the mid to late '70's.

[@timfeeley714-25]

If I remember right one of the problems also was that they ran an extra hot 190 or $195° thermostat in them to help meet emissions which helped lead to engines wearing out early, my friend Ted's Vega wagon burned so much oil that we drove around with a 5 gallon container full of used oil, one day while driving down I-5 the engine gave up the ghost suddenly and exhausted all five quarts of oil through the exhaust in about a second flat it made such a fog Bank on the freeway that we couldn't see cars until they popped out of the smoke cloud.

@@rarecars3336 I agree. The Corvette in 1975, base motor only had 165 hp and the only optional engine had 205 hp and the car didn't handle very well. The Cosworth, on the other hand, handled great. Granted it didn't have much low end power until you have the rpms up, then it went pretty good. In 1983,i bought a Shelby Charger, which was the best handling front wheel drive car in the same class size as the Cosworth and it was rated at 107 hp. I would have liked to see both cars on a road course, to see which one would win in the handling dept. Fun Times.

[@andrewk7745]

I had a 1976 Cosworth Vega. Pretty cool car. There was a plaque on the dashboard with the production number. I believe mine was between 2800-2900. It was the black and gold with white seats. I ended up spinning a main bearing and sold it to a guy that fixed it. The problem back then was that aluminum quality was horrible. The solid lifters were the coolest thing about it.

GM had a hot rodded Vega at the Mesa proving grounds for high speed tire test. The engine was based on the base Vega SOHC engine. I was surprised that they didn't use this engine. It was built on a pre 74 Vega so this engine probably wasn't available when they built this car.

[@tommissouri4871]

When my 60,000 mile warranty finally ran out, I installed a Blackjack header, put on a 2-1/2 in exhaust to a turbocharged Corvair muffler with 2-1/2 outlet. Through a friend of a friend, I acquired some of the peanut jets for the little two-barrel Holley to rejet to match the header. These jets were unavailable at the time due to emissions laws. With that, I could run mid 17s on the quarter mile. A friend did purchase a 1975 Cosworth new. My GT could beat his every time in a stoplight race or down a section we measured to be a quarter mile. He paid about $6300 out the door with options where I paid about $4100 out the door with options. At the time he bought his, a left over new blue 1974 Corvette coupe was on the dealer floor for $6500. This is why Cosworth failed. The price of a Corvette but a warmed over Vega GT could beat it.

My first car was a 75 Opel 1900 sport wagon built in Germany. It certainly was a good handling little wagon. The best part wss in 1975 they put a Bosch full multi port fuel injection system in the 1900. Definitely a better engine than the rest of the Vega offings plenty of torque and a bit of horse power at the top. A "Vega " that was also fun to drive...it's ultimate demise was Wisconsin Winters . It had 175,000 miles which wasn't to bad for the time since the engine was still running perfectly.... that engine now lives in an Opel GT replacing the 1.1 liter. I have a set of front shocks that never made it into the wagon left yet.

Dropping a Cosworth engine into a Vega was like drinking vintage Chateau Mouton Rothschild '55 from a Flintstone's jelly glass. I actually saw a Cosworth Vega in a Chevrolet Showroom in 1975. The Sticker price was higher than the loaded Chevrolet Caprice Classic Convertible standing on the other side of the room. No surprise it didn't sell.

The headers were a work of art, but I was turned off by the harmonic weight added to the rear of the transmission. Happily an enthusiastic father and son bought the car.

So many comments, so I will add one more: I am an original owner of 1976 Cosworth Vega #3517, seems to be the next to last made. I recall spending all of my savings to buy it at ~$5300. The electronic fuel injection was blamed for rough idling, unstable idle speeds, etc. Dealer changed the "computer" twice. I changed to Webers while still in warranty and never looked back. A sure way to get attention is to take it out for short ride - guys want to tell their personal story about Vegas wherever I go. Funny, in the late 1970's, back in the day when the car was my daily, nobody paid any attention. When I autocross the car today, no other car sounds the same on course - loud noise under the hood (Webers) and another unusual noise at the tail pipe. Turning 5,000 to 7,000 RPM while on course. Young guys would argue as to who made the car - Cosworth of England or Chevy. The Chevy bow tie emblems settle the argument. Yes, a strange car indeed.

[@Porsche996driver]

Have you done a video on the Monza yet? That was kind of a mature Vega, and one version had a little V8 similar story.

[@gordonstroup882]

I was..... am, a Vega lover. I only love the 1971-1973 body style, though. They were kinda fashioned like the Camaro of the same years. I actually had a 72 GT hatchback, and a 72 GT wagon. The hatchback was the dark orange with a black stripe, and the wagon was metallic silver with the black stripe. The hatchback, I rebuilt the engine, steel sleeves were pressed in for better piston ring sealment. The pistons were changed out to be 10 to 1 compression. The block and head were milled to also bump up the compression. It ended up to be 10½ to 1 comp. I installed a nice little bumpy camshaft too. A larger capacity radiator, changed the intake to a 4 barrel and installed a 550 Holley carb. A good style header for the exhaust, a new dual exhaust system, a stock 4 speed manual transmission, a posi unit in the rear axle, a set of Lakewood slapper traction bars, and some wider tires on all 4 corners made it a pretty quick little car. I drove it everywhere, here in Arizona. The cornering was great, the horsepower gain was awesome, and it was a perfect sleeper. Now the wagon.... I bought this from a friend. He had already installed a 6 point roll cage, subframe connected together, also a narrowed 12 bolt Chevy rear axle with 5:13 gears, hand made 36 inch long traction bars that bolted up to the subframe right under the front seats. They really transferred the weight and the little wagon could hop the front tires off the ground when you got on it. It had a BorgWarner 4 speed and a Hurst Super Shifter. The engine that I put into it was a 65 Corvette 327. I did quite a few changes to it, and turned out to be a ground pounding, loud thumping, wheel pulling, fast little bitty street station wagon, perfect to drive to the grocery store anytime at all, ha ha 😅.

Unfortunately, the Cosworth Vega suffered from what was often referred to as " the Arrow Syndrome" -- they went like stink in a straight line, but had serious oiling problems when going around corners. When raced, they had a tendency towards oil starvation on hard corners, an unfortunate condition in a car intended for road racing. It was a great concept and could probably have been resolved with a little bit of development effort, but by the time it was discovered, Chevrolet was already planning to drop the Vega. What could have been...

I’ve never forgotten them, I worked at a Chevy dealership in 1976.

I heard these were slow sellers, would you agree with that being someone who has first hand experience with them at the time?

I had a 1970 gt vega and loved it

[@bryanst.martin7134]

I put a 305 in a Vega wagon one weekend with my buddy. Drive shaft was a bit wonky but it was drivable. Did you know that the crash tests between Pinto and Vega were rigged? Vega was rear ended at 35mph, and the Pinto at 55mph. I was young, but I read the fine print during commercials.

I actually did not know that so thank you for sharing!

My first car was a hand me down1976 2.3 3 speed automatic transmission that would accelerate 0 to 60 in 13 sec. no wonder I never got a speeding ticket in that car. I lived in Fla. and can say the air conditioner worked great and never failed.

I always really liked the Vega, and, mini-Camaro describes it well. With todays high h,p, 4 bangers, you don't need a V8 conversion anymore - but it's still very cool. Wish there were more...

[@ML-dl1cp]

Sue me, but I think the Vega hatchback is one of the nicest looking American cars of the 70s. It had beautiful lines. Too bad GM had no idea how to properly equip, build, market, or rustproof their products. We had an Astre (Pontiac version of the Vega) when I was a kid. I always had a soft spot for it. The only Astres/Vegas I ever see anymore are tubbed-out funny cars.

[@rarecars3336]

Agree it is very rare these days to see a clean vega that isn't tubbed

[@randallhoward3231]

The engine blocks were a horrible mistake. Every once in a while, you had to fill it up with oil and check the gas. The cylinder walls were aluminum and couldn't endure the ring wear. My little brother had a 1976 Vega and it left visual evidence of it's passing. But, he purchased a factory remanufactured engine at a Chevrolet dealership. These engines had steel sleeves installed in the cylinders. Afterwards, he had a nice car that wasn't an embarrassment to drive.

I'm sure that Chevy spun the story of why they detuned the car. There is no way they would make a Vega that outperformed the Camaro or the Corvette at a lower price.

[@dukecraig2402]

All those stories are nothing but that, just stories, like all the Buick fanboys who always cry the conspiracy nonsense about GM axing the GNX because it'd out perform the Corvette, never mind the fact that the chassis was slated to be discontinued after 87 back in 84 when they started development of the next generation chassis, somehow or the other they always manage to overlook that simple fact. Don't ever believe any of those nonsense conspiracy theories about Chevy complaining to GM and having other lines discontinued, they're all nonsense that sprout up from fanboy tears, if any of that was even remotely true the cars never could have developed in the first place, none of those stories are true no matter how much someone swears "My dad/uncle/cousin/grandma worked at Pontiac/Buick/Oldsmobile and they told me...", it's all just a bunch of story telling from butt hurt fanboys.

[@moremoney2]

GM bean counters and lawyers couldn’t face the liability of another Ralph Nader. Developing more power and meeting safely and crash standards meant the structure and handling would have had to be updated. Too costly. It’s amazing that the Corvette is still alive at GM.

[@garthhancock3373]

[@GRAHAMAUS]

It's fascinating to see the cross-pollination between GM's various global design studios. The Vega GT obviously owes its fastback shape to the Opel Manta A, or perhaps that's the other way around? Not to mention the similar Holden Torana. And the Cosworth Vega's wheels were sourced from Vauxhall's ultra-rare HP Firenza, manufactured by Avon in Britain (and also used on the later HS Chevette). This is a special run-flat "safety wheel" that has a very shallow well so that a flat tyre cannot detach from the rim (I would love to know if this aspect made it onto the Vega unchanged). GM's British head of design was Wayne Cherry, an American who was a protégé of John DeLorean, and no doubt they conferred regularly, and the similarity of the design language between US and UK vehicles shows accordingly. In an era before 'world cars' and globalisation, it's only now a lot of these similarities are becoming more obvious.

[@vonhalberstadt3590]

The Pinto had an inherent edge over the Vega - huge rear wheelwells. You simply could easily fit decent tires on the Ford. The Cosworth Vega is legendary though.

[@Dangerous_Drivers_of_CA]

When I was a kid my neighbors had a 1976 Bicentennial edition Cosworth Vega.

[@Oldbmwr100rs]

A friend's dad bought one, they garaged and pampered that car, but it still had problems. One being gasoline seemed to dissolve the carb! At least it was a Durabuilt engine one with a larger radiator than the original Vegas came with. That was one of the problems, GM used a heater core as a radiator and the early engines ran hot, it was a joke how many corners they cut on that car, if they had done much of it right in the first place they would have done far better.

[@edmundanderson657]

@@Oldbmwr100rs Funny thing is other then the Cosworth there there was only 2 radiators, with AC and without. If you were having overheating issues with the 71-72s the warranty was to swap out the rad for the AC one and you got a new sensor with an indicator light under the dash. After 73 they went back to the small radiator.

[@cgss08]

The Vega got a bad rap due to the early ones. I bought a 74 Camaro new and it was so bad with all the emissions crap they put on that small block, it was terrible to drive. I got so disgusted with it I traded it in with 9K miles and got a 75 Vega GT which I drove for about 200K miles! I loved that car. I sold it to a friend who put a rebuilt engine in it and drove it for another couple of years. It was sporty and economical for its day. GM almost got it right. Too bad it had so many early issues. I think I just might look to find a restored one someday.

[@rarecars3336]

They are soo hard to find it seems. So many Vegas were either junked or cut up into drag cars. So few nice ones left

These are such cool rare cars. I never knew these existed until about 10y ago. Chevy should have sold it in Europe. They could have done rallies and races with it. In stead GM-Europe (Opel/Vauxhall) also enlisted the help of Cosworth engineering. They made the 2.4L inline4 16valve engines for the Opel Ascona 400 and Manta 400. Those cars were homologation specials that became very succesful rally cars. Even later in the early 1990's Cosworth again designed a cilinderhead for Opel/Vauxhall for the e-Kadett 2.0 GSI. That car was a frontwheel drive hatchbacks with great aerodynamics and with 155hp those were quite quick. Same for the Calibra. Cosworth also designed the cilinderhead for the Mercedes 190e-2.3L 16valve. That car won many touringcar races. Other highly succesfull rally cars with cosworth designed engines: Ford Sierra Cosworth 2wd and 4wd and Escort Cosworth 4wd. Think what could have been with that Vega Cosworth... it could have been very succesful in Europe.

[@martinmckendry6244]

Europe had Opel Ascona 400 then Manta 400, UK had Vauxhall Chevette HS and HSR from GM. But do not forget the Ford Escort Rs1600 and RS1800 with Cosworth BD series engines

[@stevejarred6484]

It's a shame that the Cosworth Vega got dragged down with the whole Vega line. Could you imagine Cosworth Vega wagons or Pontiac selling Cosworth Astras. I imagine there could have been Cosworth versions of the Monza, Sunfire, Skyhawk and Forenza as well. I think offering this engine in so many models would have brought production costs down.

[@pauljs75]

If you go into the J-body era of Skyhawk, there was the T-type which used a turbo version of the 1.8L 122 engine. But examples in original form are rare, of the few that may survive. Generally due to a turbo delete which eliminated the entire point of the T-type designation. Reliability issues as those engines had neither an electric cooling system or run-down to support the turbo, many people didn't let it idle long enough like they were supposed to after spirited driving and such resulted in cooked turbos. Those were fun because you had another 50 to 60HP vs. the fuel injected version. And gen-1 J-bodies was around 200 hundred pounds lighter than the following generation. An engine replacement might also end up losing the turbo too, as the turbo version of that engine was sourced from Brazil rather than any U.S. production. So they did have something fun, even if it's not quite the thing you're thinking of. Another rare and forgotten thing it seems.
