GM Refiles Trademark For LT5 Engine Before C7 ZR1 Launch

General Motors has refiled a trademark application with the United States Patent and Trademark Office for the name LT5.

The automaker initially filed for the LT5 trademark back in April 2013 and in this latest application, it’s been marked as the name for “Engines for automobiles, sport utility vehicles, trucks and vans”, reports GM Authority.

While GM has yet to reveal any official information about the engine, it is widely tipped to power the impending C7-generation Chevrolet Corvette ZR1. As the 6.2-liter supercharged V8 of the Z06, Cadillac CTS-V and Camaro ZL1 is thought to be near its max at 650 hp, GM is developing the all-new LT5 V8 and will ditch the supercharger in favor of two turbochargers.

All told, this new engine is expected to offer up in excess of 700 hp and will therefore necessitate a selection of cooling and visual changes when installed into the ZR1. Most significantly, additional air intakes will be found on the ZR1’s front fascia.

If reports prove accurate, we can expected to see the C7 Corvette ZR1 debut at a major motor show in 2017 before arriving on the market as a 2018 model.

    Pfft, what Ferrari F12?

      Yeah, you wish.

        I’d be willing to take that bet. Seeing as the current Z06 is 650hp, it’s not a stretch to see the ZR-1 in the 750 range and that would compare very nicely to an F12 TDF at 770hp. Curb weight would be probably the same at around 3600lbs. Yes bring this comparison on and let embarrassment ensue.

          The problem is that you’re looking only at the numbers. I adore the Z06, the ZR-1 should be even better but a naturally aspirated V12 Ferrari is on a whole different level. The performance may be similar, the ZR-1 may even be quicker but that doesn’t mean much when the F12 is such a special car.
