Overview
- Chevrolet introduced a new mid‑mounted 6.7‑liter Gen 6 LS6 V8 that replaces the LT2 and delivers 535 horsepower and 520 lb‑ft of torque.
- The Grand Sport X adds a 186‑horsepower front electric motor to the LS6 for a combined 721 horsepower and standard all‑wheel drive.
- The LS6 features forged pistons, rods and crank, redesigned heads with improved cooling, combined port and direct injection, a 13.0:1 compression ratio, updated oiling and retained dry‑sump and cylinder deactivation systems to balance power, emissions and durability.
- Chevrolet set the Grand Sport X at $23,700 over a base Grand Sport, giving the X a roughly $112,195 starting price for the coupe, and it defaults to Michelin all‑season tires while the non‑X Grand Sport can be optioned with a Z52 track package that includes Cup 2R track tires not offered on the X.
- Early media drives largely confirm Chevrolet’s performance claims with a manufacturer 0–60 mph figure of 2.4 seconds using launch control and a real‑world 2.8‑second run recorded by a reviewer on public roads, showing strong but context‑dependent straight‑line acceleration.
