Another day, and another rumor about the upcoming 2025 Chevrolet Corvette SUV. In what seems like forever, Chevrolet has finally decided to join the high-performance SUV bandwagon, giving the American automaker a legitimate competitor to the Porsche Cayenne. Most of the rumors so far have pointed out that the Corvette SUV will be electric, but it seems that won't be the case, at least initially, when it finally gets revealed to the public in the coming years.

Car and Driver continues to feed the rumor mill on the Corvette SUV, and they're claiming that it won't come out as an electric vehicle (EV), or at least not at launch. Thanks to the Alpha platform that it will allegedly utilize, the Corvette SUV will come with a broad range of high-performance engines. As a reminder, the Alpha platform is what underpins the Camaro, CT4, and CT5--all of which are rear-wheel drive (RWD) performance cars. The Alpha platform is capable of handling turbocharged four-bangers, as well as V-8 and V-6 powertrains.

The Corvette SUV Will Come In Two Sizes

Interestingly, the Car and Driver also claim that the Corvette SUV will come in two sizes. Under a new Corvette sub-brand, a Porsche Macan-sized competitor will come with the aforementioned four-cylinder and V-6 engines, while a bigger Cayenne-sized rival will come with V-6 and V-8 engines. The four-cylinder should pump out 300 horsepower, while the twin-turbo V-6 is rumored to produce 400 horsepower. The 6.2-liter V-8 comes in two outputs, 500 horsepower for the naturally-aspirated V-8, while the supercharged one will produce 682 horses.

With that in mind, this will be the first time that the Corvette nameplate will come with four cylinders, and it's something we'll need to get used to. It will allegedly start at $60,000, while buyers can upgrade the Macan-sized version of the Corvette SUV to be powered by the twin-turbo V-6.

On the other hand, the bigger Cayenne-sized rival will start off with the twin-turbo V-6, and then be upgradeable to the naturally-aspirated 500-horsepower V-8. The high-performance model that is expected to come with some form of the "Z0" designation will get the supercharged V-8 that based on the aforementioned numbers, is similar in specs to the Escalade V. The range-topping version will also come with a host of handling and chassis upgrades, including but not limited to, carbon-ceramic brakes.

The Corvette SUV is also rumored to come as standard with a 10-speed automatic--which is unsurprising given that the Corvette C8 doesn't even come with a manual, let alone the prospect of a manual high-performance SUV is almost impossible with today's market preferences. GM's magnetorheological dampers are also expected to be available as an option for the Corvette SUV.

So, what happens to the rumored electric Corvette SUV then? That won't be shelved anytime soon, because the EV model is expected to follow suit after the internal combustion engine (ICE) models. This is unlike the Mustang Mach-E, which is not available with ICE. Of course, these are still rumors, which means that a lot of details are subject to change. As for when we'll get to see the Corvette SUV, the Car And Driver also says that it might be revealed later this year, and it will arrive in dealerships in the second half of 2024.
