The C8.R's flat plane crank engine may be put in a road car

3d ago


GM casually unveiled the Corvette C8.R racecar alongside the street-legal Corvette C8 convertible last week, but the real excitement was when we heard the C8.R rev its beautiful 5.5-liter flat plane crank V8. It sounded so brilliant, so exotic, so un-American, and yet, it all seemed like a cohesive package. A loud exotic engine in a loud exotic car.

This 5.5-liter engine still has a lot of mystery around it. At the launch, representatives said the engine produces around 500 horsepower and 480 lb-ft of torque. These numbers are important when you consider the regulations from IMSA and FIA. These rules also require 300 road going examples in order for the engine to be allowed to be used.

So the big question is, what is it going into?

Are we expecting to see the 5.5-liter engine be used as an additional engine in the lineup? Everyone is jumping to the Z06 as the answer, but I think the Z06 will have way more than 500 horsepower. I think we will see this engine in the Corvette Grand Sport, and I say that because Chevrolet always treats the Grand Sport like it's some over the top vehicle, when it reality, it's a little more power, and some hash marks on the fenders. With base Corvettes putting out 495 horsepower and 470 lb-ft. It seems to make perfect sense that Chevrolet would switch the engine in order to command a higher price for the Grand Sport.

I could also be horribly wrong, so my second bet is going to be a Cadillac supercar, based on the C8, with that engine as the base engine. I would like to believe that Cadillac is holding its cards really close to its chest, and we are going to get a new halo car to champion all of the major changes to the lineup. While all of that rumor, I would like to believe that is the case.


GM is on a hot streak with the C8 Corvette, and if they can strike a deal with the UAW, then Corvette fans all around the world will be able to drive this exquisite machine. I'm personally excited to see what they do with the C8, and what other incredible things GM has in the pipeline for it.

What do you think of the C8 Corvette so far? Where do you think that flat plane crank engine will end up? Comment Below!
