For years, we thought the Cosworth Vega was a mythical creature that appeared only in automotive history books.
Until we saw one at the 2021 Goodguys Summit Racing Nationals.
“It does exist!” we exclaimed as we spotted the car alone in the parking lot outside the event—which makes us believe that, if we hadn’t decided to head to our hotel to write a Honda Z600 story at that very moment, we could’ve missed this unicorn forever.
Luckily fates aligned, and there we were, staring at the Vega’s John Player Special-inspired paint job.
Unfortunately, we couldn’t find the Vega’s owner to get the inside scoop on this particular car, so we’ll just talk about the Cosworth Vega in general terms, because it’s way more than just a stripe and decal package.
Like a lot of GM performance origin stories, the Cosworth Vega begins with John DeLorean. In 1969, he’d been tapped as Chevy’s new GM, which meant that it was his job to market the Vega—an all-new subcompact import fighter debuting in 1971.
Thanks to its success in Formula 1, DeLorean sought the help of Britain’s Cosworth engineering company to give the Vega a bit more oomph. After a few years of development, the Cosworth Vega entered the scene in 1975.
Under its hood was a unique 2.0L aluminum four-cylinder engine making 110 horsepower—for perspective, a base 1975 Corvette’s 5.7L V8 was only making 165 hp. Much of the engine’s performance can be credited to Cosworth’s cylinder head design, which featured 16 valves and dual overhead camshafts.
In another innovation, the Cosworth Vega was the first time Chevy offered electronic fuel injection.
But the engine was only part of the Cosworth Vega’s magic. It had upgraded springs, shocks, and sway bars poached from the Vega GT, and could be optioned with a limited slip differential. Power was sent through a four-speed (and later five-speed) manual transmission.
Reviews at the time were positive, with many publications favorably comparing the Cosworth Vega to some well-regarded European imports.
But alas, Cosworth’s provenance and performance were not enough to overcome the Vega’s souring reputation stemming from early manufacturing missteps. After just two years, Cosworth Vega production ended in 1976, and Chevy halted the entire Vega line a year later.
With Cosworth Vegas making up a tiny sliver of overall Vega production, they’re certainly a rare find. So, we’re glad that we were able to catch this one before it vanished back into the ether.
Are you the owner of this Vega? Do you have a similar Cosworth Vega (or frankly, any Vega) in your garage? Tell us about it in the comments below!
And if you’re a big Vega fan, you may dig this article we ran earlier on Chevy’s Spirit of America special editions.

First off Chief GM has never been involved in formula 1 and cosworth engineering was started in 1966 by two engineers Mike Constantine and Keith duckworth and was financed by Ford and the result was the 3 liter DFV Ford cosworth V8 that the lotus formula one team had exclusive rights for the first year
And this motor was so dominant by 1968 all formula 1 teams switched to the Ford cosworth except Ferrari and Ligia and Mario andretti won his world championship on a 78 lotus Ford cosworth DFE ground effects lotus with the black and gold Liberty I’ve had two cogsworth Vegas my last one being the black and gold 1976 and I truly love that car wish I had it back actually looking for one also let me give you a little of my history didn’t involved in drag racing in the 60s through my dad snowmobile racing because I’m from Michigan formula 1 racing because I’ve been blessed to watch Aryton Senna live win a few races and if you don’t know who Senna is then you know nothing about the Ford cosworth plus many times at Indy in the infield and garage area not to mention NASCAR pits and races and have been a part of one of the best super modified short track teams in the Midwest just trying to stay humble Chief just do your research
Michael Costin…not Constantine.
I currently own #0755. Bought it off the showroom floor in 1975. Most recent shows where the Iola Auto Feast and the GM Nationals.
Love the car and I plan on keeping it till I die.
Love of the Cosworth Vega lives on with the almost 300 member Cosworth Vega Owners Association. Go to http://www.cosworthvega.com to see!
Thanks for the link! Glad to hear that these cars are getting cared for. I goofed and should’ve got a better picture of the dash plaque on this one (had to take it through a closed window). I can’t decipher it here, but maybe its owner will see this article and chime in?
Been a long time John. Byron here and Lost all contact, recipes etc. Currently looking for a good rebuild kit for my 42 dcoe – 8 Webber side drafts.. thank you for selling me the new crate motor way back. It runs awesome. 80 miles so far. Any help welcome. And thanks a bunch.
I am the original owner of # 0953. Bought it in July 1975 from Ron Prince Chevy in Red Hook , New York.
A friend of mine used to own a genuine Cosworth Vega. However, it was totaled a few years ago when an inattentive driver rear ended him as he was turning into his driveway. Now, the Cosworth engine and 5 speed transmission are in a Vega wagon. While it’s not technically a Cosworth, it’s still a fun car.
Fool around with the advance cure, there was no vacuum advance on those engines, they were choked with late advance for emissions. Uncork the exhaust and a little rework of the air filter, let that little monster breathe and then let it scream!
[…] with other performance-focused GM efforts like the Cosworth Vega and Pontiac GTO, the Sprint 6 story begins with John […]
I owned four Vegas over a period of several years back in the day. A Kammback and three hatchbacks. Three were GTs and the last received a transplant. A warmed over V8 from a Monzas. It put up similar numbers to 5.0 Mustangs at the strip. One of the most fun cars I have owned.
A brand new Pontiac Astra was in my garage, there version of the Vega, I was out to prove the engines could not be that bad and were getting a bad rap, well I changed oil every 5000 miles and drove it easy, The Aluminum engine proved me wrong it was a real peace of crap at 28000 miles it was done, my neighbors Vega kept ripping the rear end from its sheet metal mounts and his engine was done at 26000 miles, I still think for a small car it had a good look.
I know a guy with a 1975 with 7 miles on it and never titled. Brought it from the dealer and it’s been sitting in his garage since. What’s it worth?
Loved these cars with a string attraction. Lack of an air conditioning option was a sales killer in the South, particularly with the great black paint finish. Why does GM develop some great cars but stops at the 5 yard line for an eventual turnover? The Fiero GT was another.

Hey that’s my CV at the Stan Hywet Father’s Day show. It’s number 2703. Unrestored with 13,600 miles. The Cosworth Vega club was very helpful with finding one and fixing some mechanical issues. What a great car.
I owned a ‘76 for a while, it was #2802. That was back in the early 80’s. I don’t know what ever became of it.
My husband owns two Cosworth Vegas, and is the original owner of one. When we first started dating in ’84, we were going through the usual ” what kind of car do you drive?” chitchat. He was amazed when I knew the background on his Vega! I think that’s how i hooked him!
We are the current caretakers of #3460 with indexed cams, posi rear and 5spd transmission. Whenever we go to shows there is a pretty good chance we will be the only Cosworth Vega attending.
I just stumbled the cross one and bought it runs drives restoring the interior front car to have
I have a 1976 cos worth Vega that has Benn garaged since Sept 2011, was running when placed in garage. The fuel pump in the tank went bad and I noticed that the inner bowl was moving around when I removed the inner fuel pump. Had it welded, but when the guy welded it, he welded it in the wrong location, so the inner fuel pump would not seat properly. So I left it alone until I could get the tank fixed properly, but I fell out of interest in the vehicle. So it is still in the garage and up for sale now. If interested please text me at 254 368-7909. By the way it is a California car.
