The 2018 Corvette is set to have a dual-overhead-cam V8 engine. At least, that’s what a recent dealer document suggests. This new engine will be called LT5 after the first DOHC engine being used on the Corvette ZR-1 back between 1990 and 1995.
The document comprises of a vehicle identification number (VIN) guide that got posted on GM’s parts operations and internal service website. Hidden in the pile of codes lies the LT5 which in other words is a 6.2-liter DOHC gasoline powered engine fitted with direct injection, eight cylinders, an aluminum block, and variable valve timing. The listed “Y” application for this engine matches with the Chevrolet Corvette. The document doesn’t mention anything about a twin-turbocharged version of the supercharged LT4 contrary to the rumors.
Even though it’s unclear in which Corvette this engine will be used, we’re pretty sure it won’t replace the LT1 which will stay intact as Corvette Stingray’s base engine as it still surfaces on the document for the year 2018 model, allocated for book codes A and Y (Camaro and Corvette). Some of the brand-new Corvette creations that could derive benefits from this engine include the Corvette Zora and the C7 ZR1. However, we wouldn’t mind seeing the Corvette ZR1 getting powered by a twin-cam LT5 V8 engine again. The DOHC system would definitely deliver on the high revs that you would wish for in any exotic car.
We’re keeping fingers crossed waiting to see what the last stance will be in regards to the DOHC engine which hasn’t been used on the Chevy for 20 years.
