2027 Chevrolet Corvette Grand Sport X Earns a 2.3-Second 60 MPH

Car and Driver has tested the 2027 Chevrolet Corvette Grand Sport X, the hybrid all-wheel-drive version that replaces the E-Ray in the lineup.

The powertrain

The Grand Sport X combines the Stingray's naturally aspirated V-8 with a front-axle electric motor borrowed from the ZR1X. Combined output is 721 hp and 665 lb-ft of torque, according to Car and Driver. The regular Grand Sport makes 535 hp and 520 lb-ft.

The battery pack sits in the tunnel between the occupants, and the system adds an estimated 300 pounds of weight. The X weighed 4,000 pounds on Car and Driver's scales.

The numbers

At the test track, the X hit 60 mph in 2.3 seconds, 0.4 second quicker than the regular Grand Sport. It runs 100 mph in 5.6 seconds and covers the quarter-mile in 10.3 seconds at 131 mph. It stops from 70 mph in 141 feet.

Car and Driver measured 1.08 g of lateral grip on the X's Michelin Pilot Sport 4S summer tires. A regular Grand Sport on optional Pilot Sport Cup 2R tires managed 1.18 g.

The hybrid also helps fuel economy. The X is rated at 18 mpg combined, while the regular Grand Sport gets 17 mpg. Car and Driver observed 14 mpg in its testing.

Pricing and equipment

The Grand Sport X starts at $112,495. The $500 Sport Performance package swaps in stiffer springs, retuned magnetorheological dampers and Michelin Pilot Sport 4S summer tires, bringing the base price to $112,995. The example Car and Driver tested was a 3LT with options that pushed the as-tested price to $140,380.

Standard equipment includes carbon-ceramic brakes, Magnetic Ride Control, enhanced powertrain cooling and Performance Traction Management. Car and Driver notes there is no Pilot Sport Cup 2R tire option for the X, and GM representatives could not explain why.

On the road, Car and Driver describes the X as a cross between a Grand Sport and an E-Ray, with a composed ride and firm brake pedal. The main complaints were vague steering feel on all-season tires and faint tire noise on some surfaces. Even so, the publication calls the differences nits, not deal-breakers.
