Chevrolet Corvette 2027 updates feature new LS6 engine and hybrid options
The 2027 Chevrolet Corvette lineup is undergoing significant technical updates, including the introduction of a new 6.7-liter LS6 small-block V8 engine. This engine produces 535 horsepower, which is 40 more than the previous LT2 engine, enabling a top speed of 200 mph.
However, EPA ratings indicate a decrease in fuel efficiency for the 2027 Stingray, which is now rated at 15 mpg city and 18 mpg combined. This drop from the previous 19 mpg combined rating is estimated by the EPA to increase fuel costs by $1,250 over five years and reduce the total driving range by 22 miles. The Grand Sport model is rated at 15/23/17 mpg.
The new LS6 engine utilizes Active Fuel Management (AFM) to improve efficiency, opting for this simpler system over the more complex Dynamic Fuel Management (DFM) to potentially avoid reliability issues. Additionally, Chevrolet is expanding its powertrain options with the Grand Sport X, a hybrid model featuring the LS6 engine paired with a front-mounted electric motor.
