New report coming from U.K. indicates the Mercedes-AMG GT R will pack somewhere in the region of 578 horsepower.
Right now, you can get the Mercedes-AMG GT in a standard configuration with 462 hp (340 kW) and in a spicy S version packing 510 hp (375 kW). The biturbo 4.0-liter V8 is a relatively new engine which means that it has a lot of unexploited potential, so there will be versions delivering more punch. The next installment of the M178 unit will propel the GT R which according to Autocar will have approximately 578 hp (425 kW).
But there’s more to the GT R than just a power upgrade. A weight loss is also planned and apparently AMG insiders are saying the high-performance coupe will shave off as much as 132 pounds (60 kilograms) compared to the GT S which tips the scales at 3,626 lbs (1,645 kg). In addition, the beefier body kit with active aerodynamics will further improve the GT R’s performances.
While details about the 0-62 mph (0-100 kph) sprint are not available at this point, the AMG GT S needs 3.8 seconds for the task, so expect the R to do it probably in 3.4-3.5 seconds. It remains to be seen whether the top speed will also see an improvement over the S which maxes out at an electronically-capped 192 mph (310 kph).
The wait is almost over, as the GT R will be introduced next month during the Goodwood Festival of Speed. The show starts on June 23rd, but we won’t be surprised if Mercedes-AMG will reveal the car online a few days earlier. Head of Mercedes-AMG Tobias Moers has already confirmed a roadster GT is pinned for a 2017 launch and it will likely receive the R treatment as well.
That’s not all. A full-blown AMG GT Black Series is on the agenda and needless to say it will be even more extreme than the forthcoming R. With the 2017 Mercedes-AMG E63 S about to get 612 hp from the biturbo V8 4.0-liter, the range-topping AMG GT is already shaping up to be a blazing fast machine, but it probably won’t be out sooner than 2018.
