Thanks to GM Authority, we know Chevrolet is planning a DOHC V-8 for the Corvette. It’s a big departure from the current approach of pushrod technology.
Supposedly, this seismic shift will happen in 2018, so it’s right around the corner. GM Authority took down leaked internal documents backing up this claim, no doubt over legal threats, but the info is out there now.
If the documents are to be believe, the LT1 and LT4 will still be part of the Corvette lineup in 2018. That opens up the possibility of the DOHC V-8 being a high-performance option, or something only used on certain models.
For anyone not familiar with Corvette lore, only one other time in the history of the car has a DOHC engine been used. Lotus designed the LT5 that powered the 1990-1995 ZR-1. Because of that, GM Authority thinks there’s a good chance the LT5 name will be making a comeback.
There’s plenty of mystery surrounding this new engine and what it means for the Corvette. No doubt more information will be leaked at some point.
