There’s a lot we do know about the 2018 C7 Corvette ZR1, but one major variable has remained a mystery: what’s powering it?
Clips from various videos have revealed a decidedly supercharged engine note, which has led many to believe a more potent 6.2-liter supercharged LT4 V8 is lurking under the hood. Now, we have some of the clearest evidence yet an LT4 will not be employed, but an all-new 6.2-liter supercharged LT5 V8 will be present.
LSXMag, via Weapon X Motorsports‘ Facebook page, uncovered the RPO code “LT5” in General Motors’ RPO system search tool. Corresponding with the “LT5” code is the following information:
- Eight cylinders
- Supercharged
- Spark Ignition Direct Injection
- Aluminum construction
- Variable Valve Timing
Notice something missing? There’s no mention of dual overhead cams. Instead, it seems more likely the ZR1 will stick with a traditional cam in block design. Though, this information doesn’t support the previously leaked documents showing a DOHC design for the LT5. That information, however, didn’t mention a supercharger.
Instead, the LT5 seems poised to improve the fuel system and will tack on a larger supercharger. The report states Eaton’s new R2650 unit may be tapped for forced induction duties. There is no mention of transmission or other components, though. We may see the C7 Corvette ZR1 gain the 10-speed automatic and DSSV dampers, both of which are available with the Camaro ZL1 and ZL1 1LE, respectfully. It only seems fair the king of Corvettes gains the latest performance trickery.
Finally, we’ll likely see an active aerodynamic system of sorts debut as well, per patent discoveries earlier this year.
One thing seems to be more clear than ever: the C7 Corvette ZR1 will make more than 650 horsepower and it will be a force to be reckoned with.

Actually it was Weapon X Motorsports in Cincinnati, OH that uncovered it and LSX Mag shared the story and wrote that in their article.
Mother wrong with no DOHC. The produce better high end power but the strength of gm’s success has been rediculous torque giving power throughout the entire bamdwidth. Part of the Camero success is that the mustang and challenger have to build up their power due to lo end torque while gm’s small block has it as low as 3000 rpm with ample power
new Zr1 is going to be a joke if there not using the A10 cause the A8 is not that good. I own one so I should know.
One wonders whether it is necessary for Chevrolet to abandon the front mid-engine rear-wheel drive of the C7 Corvette given how Ferrari still builds front engine rear wheel drive cars like the 2017 Ferrari California T.
Jeff, You should have bought a standard. You’re the joke.
