Chevy fans rejoice, because the 2027 Corvette Grand Sport is bringing us a new-generation small-block V8.
After teasing the model this past weekend, Chevrolet has now fully pulled the curtain back on the latest model to join the C8 Corvette lineup: the hotly anticipated Grand Sport. There’s a bit more to the story, though, because there’s far more to it than simply another model that slots between the Stingray and Z06. Chevy also dropped a Grand Sport X model, and you know what that letter means if you caught the ZR1X reveal. The X model, for its part, brings electrification to that brand new V8, packing a power level that slots in between the Z06 and ZR1. So, there’s much more to this Grand Sport reveal than we initially thought.
But let’s start with the headline of the 2027 Chevy Corvette Grand Sport lineup: that engine. Indeed, the LS6 small-block V8 makes its debut with this vehicle: a 6.7-liter, naturally aspirated engine kicking out 535 horsepower and 520 lb-ft of torque in the base Grand Sport. That’s a healthy improvement on the Stingray’s “old” 6.2-liter LT2 V8, which makes 495 horsepower and 470 lb-ft of torque. Like the Stingray (as well as the rest of the Corvette lineup), the new V8 sends that power through an 8-speed dual-clutch transmission.
Compared to the LT2, the 6.7L LS6 packs the same 103.25-mm (4.06-inch) cylinder bore, but a longer 100mm (3.94-inch) stroke. Along with the larger displacement, the LS6 also has a higher 13.0:1 compression ratio (to the LT2’s 11.5:1), enabling the higher output. In fact, this naturally aspirated V8 is the most powerful in the Corvette’s 73-year history, as every one of the lineup’s more potent offerings throws either forced induction (and in the ZR1X’s case, electrification) into the mix.
This engine isn’t just going to be part of the Grand Sport lineup, either. In 2027, the next-generation LS6 V8 will also make its way to the base Stingray, so this will be the standard V8 on the sub-Z06 side of the C8 Corvette’s lineup.
The Grand Sport model isn’t just about the new V8 or its looks — you can build it up through packages, too.
With the 2027 Chevy Corvette Grand Sport, the automaker is also expanding other available options, beyond just giving it a new V8. The model (and the Stingray, in due time) will also bring quad center-exit exhaust to the options menu, so it won’t just be a feature of the higher-end Corvettes this time around. The Grand Sport further brings the adaptive Magnetic Ride Control suspension setup as standard equipment, while you also get a set of Michelin Pilot Sport 4 all-season tires by default. The model gets a new brake package to help reduce brake dust and corrosion, so you get the sense that the model is geared more toward those who want to daily drive their ‘vettes.
You can gear it more toward performance, of course, through a set of packages, if you want. The Z52 Sport Performance Package is your first port of call if so, which adds in stiffer suspension (the Grand Sport gets the ‘Touring’ suspension as standard), upgraded J56-package brakes from the Z06, and stickier Michelin Pilot Sport 4S summer rubber. On top of that, the Z52 Track Performnace package goes a level higher still, giving you Michelin Pilot Sport Cup 2R tires, as well as carbon-ceramic brakes that are also an option on the Z06. The Track Performance package also beefs up the car’s aerodynamics, bringing in carbon fiber dive planes, front splitter, underbody strakes and a rear wing.
Then there’s the Grand Sport X…with 721 horsepower!
Just like the Corvette ZR1X, Chevy’s decision to similarly brand the Grand Sport X also brings a similar powertrain solution. Alongside the new LS6, there’s a front-mounted, 186-horsepower electric motor, adding another 145 lb-ft of instantaneous torque on the front axle. Thanks to that electric motor, the Grand Sport X’s total output rises to 721 horsepower, while this model also gets the same system controls to strategize how best to use that power depending on the conditions. ‘Endurance’ (enabled through hitting the Charge+) emphasizes extended lapping and consistent AWD performance, ‘Qualifying’ juggles power output to try and achieve the best lap times, and ‘Push-to-Pass’ makes all the power available on-demand.
Like the standard Grand Sport, the X also comes with Magnetic Ride Control and all-season tires as standard, though it does get teh upgraded carbon-ceramic brakes as part of the standard package. The optional Performance Package adds the Pilot Sport 4S tires in once again. Like the Corvette E-Ray, the Grand Sport X also has a ‘Stealth Mode’, allowing drivers to utilize the 1.9-kWh battery for short stints of all-electric driving up to 50 mph on the road, without firing up the V8.
Finer points of the 2027 Chevy Corvette Grand Sport
In keeping with the C8 generation’s mid-engined layout against the past-generation, front-engined Corvettes, there are a few styling tweaks on this model compared to Grand Sports of the past. The signature hash marks that usually appear on the front fenders, for example, have been moved to the back this time around. There are other similarities to past versions, though, like the C4’s Admiral Blue making a return to the latest iteration with a white center stripe and those distinctive red hashes. Pitch Gray Metallic, also shown above, is another new Corvette color option for 2027.
The 2027 Chevy Corvette Grand Sport will also offer up a Launch Edition interior package that is, to put a finer point on it, extremely blue. And if a certain song mentioning a blue Corvette just popped into your head, you’re not alone there. Nearly every interior surface is Santorini Blue, apart from the red stitching and seat belts. The Launch Edition models further get embroidered headrests, while the leather-wrapped cowl over the gauge cluster gets a red accent down the center, lining up with the center mark on the steering wheel. Finally, a waterfall speaker plaque on the back of the center console and a special Grand Sport steering wheel badge complete the look for the early-spec Grand Sport models.
On top of the Santorini Blue interior, the equally loud Adrenaline Red interior is also an option.
How much does the Grand Sport cost?
Now, you might be wondering exactly how much the 2027 Chevy Corvette Grand Sport/Grand Sport X will cost. So are we, as Chevrolet hasn’t announced formal pricing just yet. We’ll get that information closer to the launch in the second half of 2026. Odds are we’ll see the regular Grand Sport land between the Stingray and Z06 — so think $100,000-ish — while the Grand Sport X will probably come in pretty close to the Z06’s $120,300 price tag (maybe a bit higher).
