2017 Mercedes-AMG GT R revealed
According to Mercedes-AMG, the GT R “combines the driving dynamics of our AMG GT3 racing car with the everyday practicality of the AMG GT.” That's a bold claim for this new arrival, which will become a third road-going member of the range alongside the entry-level GT and the GT S.
The enhancements begin with the engine. It's still a 3,982 cc twin-turbo V8, but thanks to more boost pressure, better inter-cooling and a higher compression ratio, power and torque have been increased to 577 bhp (430 kW / 585 PS) and 700 Nm (516 lb/ft) respectively.
That output – which is up by 74 bhp (55 kW / 75 PS) and 50 Nm (36 lb/ft) compared to the GT S – gets sent to the rear wheels via a carbon fibre torque tube and a rear-mounted seven-speed AMG Speedshift dual-clutch transmission.
As a result, the GT R can reach a top speed of 197 mph (318 km/h), having accelerated from standstill to 62 mph (100 km/h) in 3.6 seconds. As would be expected, 24.7 mpg (11.4 l/100km) and carbon dioxide emissions of 259 g/km on the combined cycle indicate that efficiency isn't brilliant.
Helping the driver to make the most of the car's performance potential are a nine-stage traction control system and an electrically-controlled limited-slip differential.
The chassis has received plenty of attention too. As well as bespoke coilover suspension with manually-adjustable pre-load, the set-up includes AMG Ride Control continuously-variable adaptive damping. What's more, the rear axle gains a thicker anti-roll bar and motorsport-inspired 'uniball' spherical bearings on its lower wishbones.
Also fitted is active rear-wheel steering, which is governed by electro-mechanical actuators rather than a direct connection to the steering wheel. With a maximum deflection angle of 1.5°, the rear wheels turn in an opposite direction to the fronts up to 62 mph (100 km/h). Beyond that speed, all four wheels pivot in the same direction.
Various functional and styling bodywork changes distinguish the GT R. For instance, a completely redesigned front end incorporates a chrome-plated Panamericana grille, enlarged intakes and additional 'air curtains' that guide flow through the widened wheel arches.
Hidden from view is an under-body active aerodynamic element. Made from carbon fibre and positioned just ahead of the engine, this deploys downwards when in 'Race' mode at speeds above 50 mph (80 km/h). Consequently, a venturi effect is created that adds 40 kg (88 lbs) of downforce.
Another key component is the rear wing, which is pitch-adjustable. Forged alloy wheels shod with Michelin Pilot Sport Cup 2 tyres add to the purposeful look.
Dealers will begin accepting orders for the Mercedes-AMG GT R in November. Deliveries are then expected to begin during March 2017.
