This week, Mercedes-Benz has officially debuted its much-anticipated 2018 Mercedes-AMG GT R. The automobile boasts more motorsport technology than any other production vehicle on the planet.
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.
If you plan on tracking this, Mercedes has you in mind. The GT-R uses a dry sump oiling system to help keep the engine happily lubricated while cornering.
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.
Both the front and rear double-wishbone suspensions use forged aluminum control arms with adjustable coil-overs that still use AMG Ride Control active damping. Before hitting 62 mph, the rear-wheel steering turns the rear wheels by about 1.5 degrees in the opposite direction of the front wheels -- increasing maneuverability. From 62 mph to the GT-R's top speed of 198 mph, the wheels begin to turn the same direction as the front wheels, which should help you change lanes while you're tearing down the Autobahn.
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 2018 Mercedes-AMG GT R will arrive in U.S. dealerships by mid-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.
