Designo Selenite Grey Magno 2017 Mercedes AMG GT R Test Drive, Design, Interior – Video

 

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.
