American muscle plays in a league of its own, and the 2018 Corvette has just stepped up the game.
It was revealed today by internal GM documents that a dual-overhead-cam engine is headed to the 2018 Corvette, GM Authority said. The documents, which have since been removed from the internet, point to a 6.2-liter aluminum block DOHC engine with GM book code “Y”—marking the motor as a Corvette-exclusive.The GM documents state that the current 6.2-liter naturally-aspirated LT1 and 6.2-liter supercharged LT4 shall remain available in 2018 and marked the DOHC engine as potentially a limited-production high-performance option.
The only other time a DOHC engine has been featured in a Corvette was the Lotus-designed LT5 that powered the Corvette ZR-1 from 1990 to 1995. GM Authority speculates that Chevrolet could bring back the LT5 engine designation for this rumored 2018 motor.
All this evidence points to the DOHC engine as a hallmark feature of some as-yet-unspecified top-of-the-line Corvette for 2018. What will the new motor be in? The Corvette ZR1 or maybe the rumored mid-engine Corvette?
Let us know what you would like to see the new engine in.
