The new limited-edition top-of-the-range model AMG GT R PRO is characterised by yet further improved driving dynamics, in particular on the racetrack. The experience from the AMG GT3 and AMG GT4 racing cars entered into the development. The measures from motorsport can be clustered in four areas: suspension, lightweight construction, aerodynamics and looks.
The new AMG coil-over suspension offers even more choices for tailoring the set-up to the particular circuit. As in professional motorsport, the driver is not only able to set the spring preload length mechanically, but can now also adjust the compression and rebound of the dampers. This is done quickly and precisely without tools via a click system with an integral adjustment dial on the damper. The compression rate is adjusted separately for high-speed and low-speed movements. This means that the settings can be dialled-in for slow and fast compression movements as is common practice in motorsport. This allows influencing the body dive and roll as the well as the traction of the AMG GT R PRO even more selectively.
The front axle is fitted with an adjustable torsion bar made of lightweight 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 AMG GT R is already fitted with Uniball spherical bearings at the lower wishbones of the rear axle. The AMG GT R PRO now gets these bearings also for the upper wishbones. They are significantly more wear-resistant than conventional wishbone bearings and due to their design have no play, which means toe-in and camber do not change even under high loads. As a result, the AMG GT R PRO can be driven with even more precision.
The carbon-fibre shear panel in the underbody of the rear end also contributes to the high handling precision. This lightweight and rigid element stiffens the rear-end structure and as a result adds even more stability to the body shell.
The electronically controlled dynamic engine and transmission mounts were also retuned to further increase the agility and deliver high-precision response and clear feedback.
The standard delivery scope of the AMG GT R PRO also includes the Track Package (not for USA, Canada and China). It comprises a roll-over protection system, enclosed 4-point safety harnesses for driver and front passenger, and a 2-kg fire extinguisher (both scopes exclusively for use on the racetrack). The bolted steel roll cage of the roll-over protection system consists of a main roll bar, a brace for mounting the harnesses, two rear braces as well as a diagonal X-brace in the rear end. The system further increases the already excellent vehicle rigidity and thus also has a positive influence on the vehicle’s driving dynamics. In the USA, Canada and China, the AMG GT R PRO is fitted with matte carbon-fibre trim elements and the boot brace in place of the Track Package.
