Last June, Cadillac unveiled its Project GTP Hypercar for its return to the global racing scene. All that was announced at the time was that the car would race in both IMSA and WEC, and that it would be powered by an all-new engine. Thanks to a new teaser from Cadillac, we might get a better idea of what exactly that new engine could be.
Details were originally limited to just the fact that it’s a 5.5-litre DOHC V8, and at first it might have looked like the car would share its engine with the Corvette C8.R, which also uses a 5.5-liter DOHC V8. . However, given Cadillac’s use of the phrase “all-new” in original press material, as well as the sounds heard in this latest teaser, we’re inclined to believe it’s a completely different engine.

Unlike the C8.R, this engine was assumed to use a cross-plane crankshaft, which would make sense considering it sounds noticeably more American than many other cars competing in the class. The tone is almost reminiscent of a stock car, just with a much quicker and higher revving. In fairness, though, this engine really suits the all-American Cadillac, and it gives it a sound unlike anything else on the grid, which is what we can get behind. We’re also fans of the crisp, brutal sounds it makes on downshifts.
