The base GT is credited with 350kW/630Nm, the GTC boasts 410kW/680Nm, and the GT R and GT R Pro both have 430kW/700Nm. The AMG GT R Pro will also come fitted with a "Track Package" as standard, which comprises of a roll-over protection system, enclosed four-point safety harnesses and a 2kg fire extinguisher. From 2020, the AMG GT gets the same AMG performance steering wheel as the AMG GT 4-door coupe and updated C63. Playing as significant a role away from the eye line is the same active floor as the GT R and a new rear lip. On all models, the AMG Dynamics program is increased to add more adjustability to the ESP programs. Carbon composite brake rotors, optional on the GT R, are standard on the Pro, and the lightweight five-spoke wheels get a unique finish. A rear stiffening structure of carbon fiber further contributes to the car's rigidity.
In addition to the existing, updated AMG GT Coupe and Roadsters, there's also some new hardware for 2019. The dashboard is now fully digital with a 12.3-inch instrument cluster and a 10.25-inch multimedia display on the centre console. Created to enhance performance at the track, this Pro model was developed as an extension of the brand's GT3 and GT4 race efforts. The new GT R Pro also has 577 hp.
AMG Dynamics is able to improve high-speed stability by anticipating how the GT will react to different scenarios using sensors to detect vehicle speed, steering angle and yaw rate, among other variables. Similar to the track-spec cars, the driver cannot only set the spring preload length mechanically, but can now also adjust the compression and rebound of the dampers. The front and rear suspension setups are further stiffened by a carbon-fibre torsion bar front and hollow tube steel anti-rollbar in the rear. The AMG GT R Pro gets wear-resistant and play-free Uniball spherical bearings for the upper and lower rear control arms (the regular GT R has these bearings only on the lower arms). The sports vehicle now features the same 12.3-inch digital instrument cluster and 10.25-inch multimedia display on the centre console, as well as the same selection of TFT buttons on the transmission tunnel to adjust everything from the ESP settings to the rear spoiler position.
Mercedes-AMG Officially Reveals the All-New GT Model & Track-Focused AMG GT R Pro
At the rear, a clear-coated carbon-fibre aero element at the wheel arch on either side rises up nearly to the level of the taillamps, while the rear wing is fitted with a spoiler lip to increase downforce.
In early November, AMG brand ambassador and AMG GT3 racing driver Maro Engel completed a circuit of the Nürburgring North Loop in exactly 7.04.632 minutes driving a still disguised AMG GT R PRO.
However, there are no upgrades in terms of performance, as the GT R Pro has the same power output - 573bhp and 700Nm of torque - and top speed figure - 197mph. There have been no changes to the GT engine line-up, meaning a base GT has 476hp, the GT S has 522hp and the GT C has 557hp, as before.
