This nameplate is nothing new to the Corvette lineup, as it has been used multiple times over the years. In fact, the very first Grand Sport debuted in the 1960s alongside the second generation of the American sports car.
While the entry-level Stingray is relatively affordable, the versions introduced in recent years have steadily pushed the price higher. It’s clear that Chevrolet wanted to establish its dominance across the board. Now that it has done so, it’s time to offer a different, more accessible Corvette—a model aimed at purists who don’t focus solely on numbers.
That’s where the 2027 Corvette Grand Sport comes in. But that’s not all, as the brand has also taken the opportunity to unveil a second evolution of this variant with the Grand Sport X.
True to its original concept, the new Grand Sport features a naturally aspirated V8 with a larger displacement. The goal here is to deliver maximum power without the delay associated with any form of forced induction.
For 2027, the American sports car is powered by a 6.7-litre V8 with a 13:1 compression ratio. This setup produces 535 horsepower and 520 lb-ft of torque. By comparison, the entry-level Stingray uses a 6.2-litre V8 that delivers 495 horsepower. The Grand Sport doesn’t just benefit from a larger engine—it also receives several upgrades to the suspension, braking system, and tires.
If you’re familiar with Chevrolet’s latest approach, you’ll understand that the “X” brings several enhancements, starting with all-wheel drive. This is made possible by the addition of an electric motor on the front axle. Naturally, this boosts total output to 721 horsepower in the Grand Sport X.
There’s no doubt these two models are highly anticipated.
