The 2027 Chevrolet Corvette Grand Sport X produces 721 combined horsepower from a hybrid AWD system new to the Corvette lineup. This is the first Corvette to pair a naturally aspirated LS6 V8 with a front-mounted electric drive unit for all-wheel traction. This page covers every trim, spec, and upgrade, with inventory available at Greg Hubler Chevrolet serving Camby, IN and surrounding communities.
The Grand Sport X is an all-new model for 2027, not a carry-over refresh. It introduces Corvette’s first gas/electric hybrid powertrain built around the next-generation 6.7L LS6 V8, which is also slated for the 2027 Corvette Stingray. The front axle now carries an electric drive unit that contributes 186 hp and 145 lb-ft of torque on top of the V8’s 535 hp and 520 lb-ft, pushing combined output to 721 hp. A 1.9 kWh lithium-ion battery, sized for maximum responsiveness rather than EV range, feeds that unit.
Beyond the powertrain, the Grand Sport X arrives with a widened body built around the Grand Sport heritage: an integrated rear spoiler, wide side air inlets, and forged aluminum wheels in four exclusive finishes. Two EV-influenced drive modes are new to Corvette: Stealth mode, all-electric front axle up to 50 mph, and Shuttle mode, low-speed electric-only up to 23 mph. Track telemetry, lap analysis, and automated coaching are now integrated directly into the vehicle’s displays without requiring a phone or laptop.
An Interior Launch Edition, exclusive to inaugural 2027 models, adds Santorini Blue Dipped interior trim, custom stitching, embossed headrest logos, and a waterfall badge plaque.
The Grand Sport X is offered in Coupe and Convertible body styles, each available in three content levels. No MSRP or pricing is listed here; see the inventory page for current figures.
The entry point includes the full hybrid AWD powertrain, Magnetic Ride Control, 8-way power GT1 seats with Mulan leather surfaces, a Bose 10-speaker premium audio system, wireless phone projection, wireless charging, and a Head-Up Display. The Coupe comes with a removable roof panel.
2LT builds on 1LT with a 14-speaker Bose Performance Series system, heated and ventilated seats with power lumbar and wing adjustment, the Performance Data Recorder, Rear Cross Traffic Alert, Side Blind Zone Alert, and an HD Curb View Camera.
The top content level adds 14 interior color options, a custom leather-wrapped instrument panel and doors, sueded microfiber upper interior trim, and GT2 seats with Napa leather surfaces.
The coupe trim range spans from 1LT through 3LT. The convertible spans 1LT through 3LT as well, with 2LT available exclusively in the convertible body.

The naturally aspirated LS6 6.7L V8 anchors the Grand Sport X. Key engine details include a 100 mm stroke, 13.0:1 compression ratio, the highest ever in a Corvette V8, and a new continuously variable oil pump that maintains optimal pressure across all driving conditions.
The front-mounted electric drive unit adds AWD traction by independently driving the front wheels, a layout that keeps the V8’s rear-wheel-drive character intact while improving grip in varied conditions. Power routes through an 8-speed dual-clutch automatic transmission.
Chevrolet quotes a 0-to-60 time of 2.4 seconds and a quarter mile of 10.4 seconds at 131 mph on available configurations. 0-60 and quarter-mile testing methodology Carbon ceramic brakes and all-season tires are standard, making the Grand Sport X functional across a broader weather range than a track-only supercar. An available quad center exhaust system amplifies throttle response with a signature sound.
The Grand Sport X seats two in a driver-focused cockpit. Cargo capacity behind the seats is 12.5 cu ft, competitive for a two-seat sports car in this segment. The interior is anchored by a flat-bottom steering wheel, digital gauge cluster, and an angular dashboard layout that keeps controls within the driver’s reach.
At the 1LT level, GT1 seats with Mulan leather surfaces and 8-way power adjustment are standard. Moving to 3LT unlocks GT2 seats with Napa leather, 14 interior color choices, leather-wrapped instrument panel and door trim, and sueded microfiber upper surfaces. The Interior Launch Edition, available only on 2027 debut models, adds the Santorini Blue Dipped color scheme and embossed headrest logos for buyers who want a collector-ready interior from day one.
Large display screens serve as the command center, running performance apps alongside standard infotainment. Google built-in compatibility is included. Wireless phone projection and a wireless charging pad are standard across all trims.
The Performance Data Recorder, available on 2LT and included in 3LT, integrates track telemetry directly into the displays. Drivers can review lap data through a detailed graphical analysis, compare sessions with side-by-side video playback, and receive automated speed coaching tips, all without connecting an external device.
Drive modes include the standard sport and track settings alongside two new additions: Stealth mode for electric-only front-axle propulsion up to 50 mph, and Shuttle mode for low-speed electric-only movement up to 23 mph. Magnetic Ride Control is standard on every Grand Sport X trim, continuously adjusting suspension damping for road or track conditions.
Standard safety equipment on every 2027 Grand Sport X includes:
The 2LT and 3LT trims add Rear Cross Traffic Alert, Side Blind Zone Alert, and an HD Curb View Camera. These systems extend the car’s situational awareness during parking and low-speed maneuvering, which matters on a vehicle with a wide body and limited rear sight lines.
The Grand Sport X targets Corvette buyers who want the raw character of a large-displacement V8 but also want all-season grip and modern powertrain technology without moving to a fully electric platform. Stealth and Shuttle modes make the car usable in parking garages, neighborhoods, and noise-restricted areas where a full V8 start would be intrusive.
Compared to the prior-year Corvette lineup, the Grand Sport X is a substantial step. The 6.7L LS6 V8 is a larger-displacement engine than any Corvette V8 offered before it, and the hybrid AWD system is entirely new to the nameplate. Buyers upgrading from a C8 Stingray will find a wider body, more power, and traction the Stingray’s rear-wheel-drive layout cannot match in cold or wet conditions common to Indiana winters.
For Camby-area drivers and buyers across the greater Indianapolis region, the Grand Sport X represents a car that can serve as a daily driver in spring and fall, a track tool in summer, and a usable performance car through mixed-weather stretches that would sideline a rear-drive supercar.
