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.
