A new adjustable carbonfibre torsion bar has been added to the front axle, while the car’s upper wishbones also use Uniball spherical bearings, reducing play and improving wear resistance. A carbonfibre shear panel reduces weight and stiffens the rear-end structure further, too, while retuned dynamic engine and transmission mounts also feature.
Certain markets include a Track Package with the AMG GT R Pro, which comprises of a steel cage roll-over protection system, four-point safety harnesses for both front seats, and a fire extinguisher. Mercedes claims the roll over system with its multiple steel bracing points further increases structural stiffness and improves driving dynamics.
External aerodynamic improvements include an extended front splitter with carbon fibre ‘flics’, new front wing louvres that reduce front axle lift, and a new rear spoiler with milled aluminium brackets and a lip that increases rear axle downforce. Carbon is also used in the GT R Pro’s roof and side sill strips.
The GT R Pro is marked out visually in its motor show debut spec by Selenite Grey paint combined with the option of new light green stripes running across the bonnet, roof, side panels and rear hatch. Other colour combinations are available, however.
Mercedes-AMG GT range changes: Interior and chassis improvements
The most visible changes to the standard AMG GT range are to be found inside. Inspiration has been taken from the recently launched AMG GT 4-door, with a new configurable 12.3in digital instrument display replacing the old analogue dials. The central multimedia display has also been redesigned with a new 10.25in screen and updated graphics.
A new steering wheel brings with it touch capacitive buttons, allowing personalisation of the instrument display and various other functions via a vertical finger swipe. Also included are new buttons mounted off the wheel’s centre that feature a small TFT colour display showing the car’s current chassis, transmission, exhaust and rear spoiler configuration. Mercedes claims the new wheel controls allow the driver to configure most major features in the car without having to take their hands off the wheel.
New technology includes an ‘AMG Track Pace’ data logger, described as a ‘virtual race engineer’, which while driving on a track can record more than 80 vehicle-specific data sets 10 times per second. It does this via GPS data as well as various sensors in the car, and is designed to show the driver various ways to improve their lap times.
Exterior tweaks are relatively minor, but include new LED headlights with a design borrowed from the car’s four-door sibling, a redesigned rear bumper and diffuser, and some new personalisation options, exterior colours and alloy wheel designs.
