Overview
- Chevrolet introduced a new 6.7‑liter ‘Gen 6’ LS6 V8 that replaces the LT2 and is available in the Stingray, Grand Sport and Grand Sport X, with the LS6 rated at 535 horsepower and 520 lb‑ft of torque.
- The Grand Sport X adds a 186‑horsepower front electric motor to create an all‑wheel‑drive Corvette with a combined 721 horsepower and a factory 0–60 claim of 2.4 seconds using launch control.
- Independent testing at the Atlanta Motorsports Park drive event produced a 0–60 run of 2.8 seconds on an unprepped road and noted very composed, easy launches rather than dramatic wheelspin.
- The Grand Sport X carries a roughly $23,700 premium over a base Grand Sport with a starting coupe price near $112,195 and it comes standard with Michelin all‑season tires while track‑oriented Cup 2R tires are not offered on the X.
- Chevy engineered the LS6 with forged internals, redesigned cooling passages, revised oiling, combined port and direct injection and a 13.0:1 compression ratio to raise power while meeting emissions and durability goals.
