LT7 Engine Leak on Corvette Museum Shipping Pallet

With all-electric (synthesized) battery beats coming from General Motors’ tallest towers, it’s crazy to believe the same company created something like the C8 Corvette Z06. It is powered by a record-breaking V8 engine, the LT6, which develops 670 horsepower at 8,400 rpm. In doing so, it is the most powerful naturally aspirated V8 production engine of all time, the largest displacement and highest torque flat-plane crank V8 of any flat-plane V8. It’s a one-of-a-kind experience, and can only be found in the Z06. That being said, you’d be crazy to think the Corvette C8 story ends with this all-engine world beater. There are several other C8 variants in development, as well as several other powertrains. Up next is the C8 Corvette ZR1, which will be powered by an even more powerful LT7 engine. And while we’ve provided exclusive details about this upcoming product, there’s been little physical evidence so far. However, the world recently got a clue about the LT7 program thanks to the writing on a National Corvette Museum shipping crate.

General Motors LT7 V8 engine: details

The image, published on the Mid-Engine Corvette Forum, looks pretty average; we see an LT6 V8 Corvette Z06 engine sitting on a pallet in all its glory, with harnesses attached to keep the engine secure. But, after taking a look at the wording on the palette, our plot begins to culminate. “Gamma LT6, beta LT7, front.” The engine we see here is an LT6, but this pallet is intended for multiple uses.

Like the LT6, the LT7 will be a 5.5-liter twin-turbo DOHC engine. And with a pair of turbochargers, it’s expected to be the most powerful production GM V8 ever with around 850 horsepower and 825 lb-ft of torque. It will be exclusive to the most powerful Corvette C8 variants, starting with the Corvette C8 ZR1. The sequel to this supercar will be the C8 Corvette Zora – a hybrid hypercar that’s expected to have around 1,000 total horsepower. This apex predator will be powered by the LT7 powering the rear wheels, mated to two electric motors that will power the front wheels.

The LT7 chapter of Corvette history will appear in the middle of the decade, as engineers are currently preparing the next E-Ray hybrid. This new C8 will feature the same LT2 engine as the base Stingray, paired with electric motors. It will be the first Corvette hybrid with all-wheel drive. Along the way, several other Corvette products will come to light, as GM looks to expand the nameplate to a family of vehicles. That includes a Porsche-Taycan-fighting electric sedan, as well as an all-electric SUV.
