Hold onto your hats, Corvette fans! A bombshell leak might have just revealed the secret heart of the upcoming 2027 Corvette Grand Sport. It looks like Chevrolet is bringing back this legendary nameplate, and it's packing some serious heat under the hood.
This is a big deal because the Grand Sport is more than just a trim; it's a statement. It represents a sweet spot of performance and value that many Corvette enthusiasts crave.
The buzz started with a leak from the GM Parts Book, the same source that spilled the beans on the C8 ZR1's engine back in the day. This time, the leak points to an all-new engine for the Grand Sport, potentially called the LS6 V8. Instead of simply tweaking the existing Stingray or Z06 engines, GM seems to be going all-in with a fresh powerplant.
What's so special about this LS6? Well, the leak suggests it will be a 6.7-liter (409 cubic inches) beast, featuring an aluminum block and both direct and port fuel injection. This combination hints at a potent and responsive engine.
But here's where it gets controversial: Early speculation suggested the LS6 might come in 5.5-liter or 6.6-liter configurations. The leaked information suggests that the engine will be a 6.7-liter.
Adding fuel to the fire, a deleted YouTube video from Corvette insider Rick Conti showcased the purported exhaust note of the new Grand Sport. While the video is gone, reports say it delivered a classic, throaty V8 sound that's sure to get hearts racing.
So, how much power can we expect? That's the million-dollar question. The current C8 lineup has some space to fill. The base Stingray offers 495 horsepower, while the E-Ray boasts 655 horsepower, and the Z06 hits 670 horsepower. Experts predict that the Grand Sport could land somewhere between 550 and 600 horsepower.
And this is the part most people miss: The pricing strategy could be just as crucial. The Stingray starts at around $70,000, while the E-Ray jumps to about $108,600. If Chevrolet can position the Grand Sport between $85,000 and $100,000, they could have a real winner on their hands. It would offer a compelling blend of performance and value, potentially making it the most popular model in the C8 range.
