Internal Documents Suggest LT5 DOHC V8 Engine for the 2018 Corvette ZR1


It looks like that LT5 rumor for the 2018 Corvette ZR1 was correct! But the news gets even better. The new V8 will be the first dual overhead cam engine to power a Corvette since the C4 generation’s Corvette ZR-1 ended after the 1995 model year.

The LT5 confirmation was made after a redditor discovered the engine code tucked away in GM service department manual that lists the engines for its 2018 model year vehicles.

The document was posted on GM’s internal service and parts website. One of the pages includes codes and applications for “Passenger Car Engines for GMNA”. After the listings for the LT4 and LT1, there is an LT5 as the engine code, while the “Y” designates it as for the Corvette.

This fits with the rumors that we’ve heard about a new engine for the 2018 Corvette ZR1 prototypes we’ve seen running around the country over the last few months. It could potentially also find its way to the mid engine C8 Corvette.

In fact, if you go back and look at the Car and Driver report from Don Sherman back in May 2016, he suggested a four-cam, 32 valve V8 engine was destined for the performance version of the C8 while the base C8 will start off with the LT1 engine.

But with the LT5 name, it’s almost certain that it will make its appearance first in that big wing 2018 ZR1 that is now taking shape as the ultimate track Corvette.

It’s been rumored that GM is targeting 750 horsepower for the car and that the fact that it will come as a naturally aspirated instead of forced induction will make a lot of the track guys very happy.

The only two questions we have is when and how much!
