Official: Mercedes-AMG GT3 Unveiled With 6.3-Liter V8 And No Turbos

Mercedes' hardcore GT3 racer arrives with the SLS AMG's big bad V8!

After leaked images appeared yesterday, Mercedes has now officially unveiled its new GT3 racer and the big news is what’s lurking under the hood. While the Mercedes-AMG GT3 is based on the AMG GT, power will come from the same naturally-aspirated 6.3-liter V8 as the SLS AMG GT3 car it replaces. With an estimated output of around 550-600 hp, the GT3 racer will be better equipped than the road car which uses a 503-hp 4.0-liter twin-turbo V8.

It will also boast lots of revs, a six-speed sequential gearbox motivating the rear wheels and, with zero turbos, will lap the racetrack emitting “the sonorous sound of the V8.” Using the AMG GT as a base, Mercedes added wider tracks, a bigger diffuser topped with a massive rear wing, larger air intakes, and a stripped-out interior with integrated steel rollcage. A double wishbone suspension has been fitted and mass reduced by using carbon fiber for the engine cover, doors, front wings, side skirts, diffuser and boot lid. "We are entering a hard-fought, hotly contested competitive environment with the new Mercedes-AMG GT3.

"The high technological standards are spurring us on to push to take pole position with our new customer racing car.You can only give credible proof of your ambition to lead if you're beating the very best in the game," said Mercedes-AMG boss Tobias Moers. The new Mercedes-AMG GT3 will arrive in Geneva wearing a matte gray paintjob. We’ll bring you more pictures, and hopefully additional details, from the show floor next week.
