June seems to be the month of novelties for Mercedes. After the new E-Class Estate promised to come out into the light, we’ve got the Mercedes-AMG GT R supercar expected to debut at this year’s Goodwood Festival of Speed.

With 462 HP for the standard version and 510 for the S variant, the Mercedes-AMG GT needed a family member to fight the Porsche 911 GT3 RS. So here it is, in the shape of a GT R propelled by the still new 4.0-liter V8 biturbo, but with as much as 578 HP, that might take it from zero to hero in about 3.6 seconds, which makes it 0.3 seconds faster than the current top version of the GT.

The GT S, with its current 1,645 kg (3,626 lbs) will go on a diet to live up to the demands and performance of the road-going, yet track-oriented GT R. The new Affalterbach beast is expected to go beyond the 310 km/h (192 mph) electronically limited speed of the GT S. The almost 600 HP monster has been spied again and again, heavily camouflaged, testing on public roads, before its imminent arrival.

If rumors should confirm, we are set to see the fireball in the flash at the Goodwood Festival of Speed, opening on June, 23rd. The Mercedes-AMG GT R will likely hit the showrooms by the end of summer.
