2020 Mercedes-AMG GT R PRO first drive: Bring your tools

But first, all 2020 AMG GT models feature a few changes of note. Cosmetically, each trim level of GT gets its own custom exhaust tips. And the GT now has LED head and taillights, a redesigned rear diffuser (that’s mostly for show) and new wheels. Inside there’s a new steering wheel design with added buttons, a 12.3-inch screen to function as an instrument panel and a 10.25-inch screen to handle audio, navigation, Apple Car Play, Android Auto and other common premium car duties. The lower center console contains the usual shifter and central control for the aforementioned screen. And now eight “display buttons,” four on either side, each with its own screen displays the setting of said controls. Volume, for example, shows a red bar to indicate the level right there. That joins drive mode, trans (drive or manual), dampers, stability control, auto stop/start, rear wing up or down, and exhaust loudness.Taking cues from the recently released GT four-door, all GTs now have AMG Dynamics to play with, an integrated driving control system that uses available sensors to detect speed, steering angle, yaw rate. AMG Dynamics manipulates how rear-axle steering, torque vectoring by brake and the electronically controlled limited-slip differential operate. It has four settings: basic, advanced, pro and master. These four settings are tied to drive modes called AMG Dynamic Select. Basic is part of slippery and comfort. Advanced comes on in sport. Pro is part of sport plus. And master is only available on GT C and GT R in race mode and only with stability control off.Finally, there’s AMG Track Pace, a “virtual race engineer” data recorder. Track Pace collects data at 10 hertz and records 80 vehicle specific data points as well as lap and sector times. It’s also color coordinated: green or red to indicate faster or slower. Track Pace uses GPS data and sensors from the car (accelerometers, gyroscope, steering angle, wheels speeds) to give the driver a detailed understanding of the lap. And some well-known tracks are already stored in the system.
