Cosworth Building New Cadillac Hot V Cylinder Heads, Hints at Future C8 Corvette Engine



We don’t know officially if there will even be a mid-engine C8 Corvette.

But already the rumor mills are spinning about the possibility of the legendary Cosworth company providing one of the more powerful engine versions for the next Corvette.

In a story about Cosworth’s new offices and factory in Shelby Township north of Detroit, Forbes is reporting that the company’s first product from that new facility will be cylinder heads for the 4.2-liter twin-turbo V8 that will debut in the 2019 Cadillac CTS V-Sport.

Forbes says no one from Cosworth would comment about upcoming products, but the website speculated that at least one derivative of the Cadillac V8 could be a more powerful version for use in the mid-engine Corvette.

We do know that Cosworth does have more products in the pipeline. “By the end of 2019, the plant will add more equipment to expand capacity for this and other derivatives,” said manufacturing engineer Ken Bowers, which would certainly fit in with the rumored timeline of Chevy eventually offering more powerful mid-engine Corvette versions as it’s done with previous generations.

Cosworth, which was founded in England 60 years ago by Mike Costin and Keith Duckworth, definitely has a long history with General Motors, including the 2.0-liter twin-cam four-cylinder engine in the mid-1970s for the Chevrolet Cosworth Vega.

More recently, the company has been producing its AliveDrive system available in the Chevrolet Corvette and Camaro where it is, of course, known as the Performance Data Recorder.

  1. As an owner of a Cadillac 2011 CTS-V, 27K mi. and running on my second read differential(whining after 5K mi.), I’d think Cadillac would better serve it’s customer base by having Cosworth re-design a 3rd member that will work in the “V” series vehicles.
    There are no parts available to repair differentials whose side bearings wear prematurely because the were not designed to handle the torque of the “V” supercharged engine, then causing lash to change leading to whining, and then failure. Their only warranty fix was to change out the entire 3rd member with the stock one (which goes out just like the originally installed one), AND NOW IS A DISCONTINUED ITEM. That’s right, the Cadillac Motor Division has NO fix for their faulty differential. Should be illegal for them to leave customers holding the bag on such a new vehicle. Shame on them!

  2. Ask for GM P/N SKF 32010 – V2 differential side bearing, and have your local drive-line shop replace it for you.
