The 2027 Chevrolet Corvette Grand Sport pairs a 535-horsepower naturally aspirated 6.7L LS6 V8 with the wide body previously reserved for the Z06, and it starts at $86,000 before the $2,495 destination charge. Chevrolet quotes 2.75 seconds to 60 mph and a 10.95-second quarter mile at 124 mph with available equipment. Coupe or convertible, three equipment levels, and 520 lb-ft of torque that Chevrolet calls the highest of any naturally aspirated production V8 ever built.

For a Tulsa buyer this is usually a second car, garaged off South Memorial Drive or out past the Creek Turnpike, driven hard on clear weekends and parked when the weather turns. That makes the real question less about lap times and more about how much of the year the car is usable. This page covers the engine, the three equipment levels and what each one costs, the cabin, the technology, safety equipment, and which configuration fits which driver. Jim Norton T-Town Chevrolet stocks the Grand Sport and can order one built to spec.

2027 Corvette Grand Sport Engines and Powertrain Options

One engine, and it is the reason this car exists: a next-generation 6.7L LS6 V8, naturally aspirated, 409 cubic inches, making 535 horsepower and 520 lb-ft of torque. Chevrolet describes that torque figure as the highest of any naturally aspirated production V8 ever. There is no turbocharger and no supercharger anywhere in the Grand Sport, which is worth saying plainly because the twin-turbo engine in the ZR1 carries a similar displacement and gets confused with it constantly.

The LS6 6.7L V8

The LS6 runs a 13.0:1 compression ratio, the highest Chevrolet has used in a Corvette V8, with direct and port injection and Active Fuel Management. A new continuously variable oil pump holds oil pressure across the range, which matters on a car that will see sustained high rpm. Power goes rearward through an eight-speed dual-clutch transaxle with an electronic limited-slip differential. No manual gearbox is offered on this generation.

The Grand Sport X and its electric front axle

The Grand Sport X uses the same LS6 V8 at the rear and adds an electric drive unit to the front axle contributing 186 horsepower and 145 lb-ft, for 721 combined horsepower and all-wheel drive. A 1.9 kWh lithium-ion battery feeds it. There is no plug and no charge port; the system charges itself as you drive. Chevrolet quotes 2.4 seconds to 60 mph and 10.4 seconds at 131 mph for the X, and lists it as available in fall 2026. It is covered in depth on the Grand Sport versus Grand Sport X comparison.

Corvette Grand Sport Trim Lineup and Pricing

Three equipment levels, and every one of them gets the full 535 horsepower. Nothing about the engine changes as you climb the ladder, so the choice is entirely about cabin materials, audio and driver aids. Prices below exclude the $2,495 destination charge.

Equipment level	Starting MSRP	What it adds
1LT	$86,000	Removable roof panel, 10-speaker Bose audio, eight-way power GT1 seats in Mulan leather, wireless phone charger, rear camera and rear camera mirror
2LT	$93,100	Everything on 1LT plus 14-speaker Bose Performance Series audio, heated and ventilated seats with power lumbar and wing adjustment, performance data recorder, rear cross traffic and side blind zone alerts, and a head-up display
3LT	$97,750	Everything on 2LT plus 14 interior colour options, a custom leather-wrapped instrument panel and doors, sueded microfiber upper trim, and GT2 seats in Napa leather

Two performance packages sit on top of that ladder. The Z52 Sport Performance Package adds performance brakes and high-performance tyres. The Z52 Track Performance Package adds carbon-ceramic brakes, Michelin Pilot Sport Cup 2 R tyres, the quad centre exhaust and the Carbon Fiber Aero Package, which itself brings a high wing, dive planes, rockers and a front splitter. The full ladder and the step-up economics are laid out on the Grand Sport trims page.

Technology and Connectivity

Wireless phone projection and a wireless charging pad in the centre console are standard on every Grand Sport, and the car is Google built-in compatible. The cabin is built around large display screens with the driver at the centre of the layout rather than the passenger.

The configurable Performance App displays live horsepower and torque graphs over selectable intervals alongside vehicle capability data. From 2LT upward the Performance Data Recorder is standard, which integrates lap data, automated coaching tips and side-by-side video comparison into the car's own displays with no laptop involved. Performance Traction Management and the selectable drive modes are part of the same system. The interior and technology page goes through the display layout in detail.

Interior and Comfort

Three seat designs, and which ones you can order depends on the equipment level. The GT1 seat is standard on 1LT and 2LT, wrapped in genuine Mulan leather and built for distance rather than lap times. The GT2 seat is available on 2LT and standard on 3LT, adding carbon-fibre trim, a seatback halo and Napa leather. The Competition Sport seat is available and pairs Napa leather with performance textile in the high-wear areas; on 1LT that textile covers the whole seat.

A driver and passenger combination is offered that puts a Competition Sport seat on the driver's side and a GT2 alongside it, available only with the asymmetrical Adrenaline Red or Santorini Blue interiors. On 3LT the instrument panel and doors are wrapped in custom leather with sueded microfiber across the upper trim, and 14 interior colour combinations are on the order sheet. The inaugural Launch Edition adds a Santorini Blue dipped cabin, custom stitching, embossed headrest logos and a waterfall badge plaque.

Cargo and Passenger Space

Two seats and 9.1 cubic feet of luggage room split between a front trunk and a rear compartment. That is the wide-body figure, and it is genuinely usable for two people on a weekend run out toward Grand Lake, provided you pack soft bags rather than hard cases. The coupe's roof panel is removable, and it stows in the rear compartment, which means the roof and a full weekend's luggage compete for the same space. Plan for one or the other rather than both.

The convertible sidesteps that trade-off with a power hardtop that folds without eating the front trunk. The fuel tank holds 18.5 gallons, which on a naturally aspirated V8 driven the way this one invites is worth knowing before a run down US-75.

Safety and Driver Assistance

Every Grand Sport carries an HD rear vision camera and a rear camera mirror as standard, along with the automatic emergency braking and forward collision alert that are standard across the Chevrolet range. Rear cross traffic alert and side blind zone alert become standard from 2LT, which on a car this wide and this low is the single most useful equipment jump for anyone parking in a downtown Tulsa garage.

Hands-free driving is one thing the Corvette leaves out: there is no Super Cruise and no adaptive cruise control anywhere in the range. Crash-test ratings are published by NHTSA and the IIHS, and neither body has rated the Corvette; check both directly for the current position.
