The Mercedes AMG GT-R
Mercedes-AMG unveiled the newest member of its AMG GT family -- the AMG GT-R, at the Goodwood Festival of Speed over the weekend. The latest weapon in Mercedes' arsenal takes what it's learned from the road-going GT and GT-S coupes and race-ready GT3 and brings it all together.
The hand-built DOHC 4.0-liter twin-turbocharged V8 powering the GT-R sits in same mid-front position as the rest of the GT lineup, but churns out 74 hp more than the current top-performing GT-S. This bump brings the GT-R's total output to 577 hp. The two turbos spool to a maximum speed of 186,000 revolutions per minute and stop building boost at 19.6 psi. That air is then rushed through liquid-to-air intercoolers before it’s stuffed into the engine.
All those ponies go to the rear 20-inch lightweight aluminum wheels by way of a seven-speed dual clutch transaxle. Nestled inside the transaxle is also a much-needed limited slip differential.
While the power is undeniably impressive, it’s not all that's special about this Benz. This AMG GT-R sports rear-wheel steering, active aero and a double-wishbone coil-over front and rear suspension. The active aero kicks on in race mode, while going over 50 mph. The system drops a carbon fiber underbody spoiler just in front of the engine by 1.6 inches -- reducing front axle lift by over 80 pounds at 155 mph.

Responsible for slowing this beast are the gigantic standard equipment 15.4-inch front and 14.2-inch rear perforated steel rotors. If that isn’t good enough, you can spring for the 15.8-inch front and 14.2-inch rear carbon ceramic rotors.
The AMG GT-R will roll into dealers around this time in 2017, but it won’t be cheap. Mercedes hasn’t released the price yet, but considering the base AMG GT-S starts at $130,825 -- we can only imagine how much extra it’ll be.
