The entire Mercedes-AMG GT line-up has received a refresh and a new top-of-the-range model has been added. It’s called the GT R Pro. Simply put, the Pro borrows from motorsport in four areas: suspension, lightweight construction, aerodynamics and looks.
The body gets redesigned front apron with additional flics made of clear-coated carbon fibre. There are louvres too on the front fenders which contribute to reducing front-axle lift. At the rear, a clear-coated carbon fibre aero element at the wheel arch on either side rises up almost to the level of the taillights.
The Airpanel active air regulation system in the front apron and the large aerofoil on the hatch, are all part of the standard specification. In addition, the rear aerofoil is fitted with a spoiler lip (gurney), which increases downforce at the rear axle, and now sits on milled aluminium brackets.
The standard Carbon Package I includes front splitter, side sill trim strips, diffuser in clear-coated carbon-fibre finish and carbon-fibre roof with recessed centre. In addition to a host of carbon-fibre components, the standard-fit ceramic high-performance compound braking system and lightweight AMG Performance 5-double-spoke forged wheels further save the weight.
Interiors get AMG bucket seats made of clear-coated carbon fibre. However, for U.S., Canada and Chinese markets, the GT R Pro is equipped with AMG Performance seats as standard. Also included is the Track Package which comprises of a roll-over protection system, enclosed 4-point safety harnesses for driver and front passenger, and a 2 kg (4.4 lbs) fire extinguisher. Again, for North American and Chinese markets, the Pro is fitted with matte carbon-fibre trim elements and boot brace instead of the Track Package.
As for the suspension, the driver is not only be able to set the spring preload length mechanically, but can now also adjust the compression and rebound of the dampers. This can be done without tools via a click system with an adjustment dial on the damper. The compression rate is adjusted separately for high-speed and low-speed movements.
The front axle is fitted with an adjustable torsion bar made of carbon fibre. Its counterpart at the rear is made of steel, is likewise adjustable and also saves weight due to its hollow tube design.
The GT R is already fitted with Uniball spherical bearings at the lower wishbones of the rear axle. The GT R Pro now gets these bearings also for the upper wishbones. Apparently, they are significantly more wear-resistant than conventional wishbone bearings and due to their design have no play, the toe-in and camber do not change even under high loads. As a result, the Pro can be driven with even more precision, says Mercedes.
The 3,982 cc V8 biturbo motor develops the same 430 kW (585 hp) at 6,250 rpm and 700 Nm (516 lb-ft) of torque between 2,100-5,500 rpm. A 0-100 km/h (62 mph) acceleration is claimed to happen in 3.6 seconds and a top speed of 318 km/h (198 mph).
The Mercedes-AMG GT R Pro will be produced in limited numbers, but we don’t know how many just yet.
