implemented AMG Track Pace here in the Mercedes-AMG E 63 S 4MATIC+. The data collection is insanely precise, and yet it can be read at a glance and immediately understood.” WWith a couple of hand movements on the COMAND controller, we now learn the full truth of our previous lap. The presentation of the sensor measurements on the display can be individually customized. To Karl, the positions of the gas and brake pedal are most important for the initial analysis: “This is where you can immediately see where you’ve lost time. The other variables will come into effect when you’re no longer making any mistakes on the brake and the throttle,” he says as he scrolls from field to field and compares our hot lap together with his best lap time from that morning. AMG Track Pace is a sporty kind of assistance system. It offers the opportunity to analyze your own performance as well as that of the vehicle and set new benchmarks. As an integral component of the COMAND Online architecture, the feature has full access to all of the vehicle’s control modules and sensors — and in real time, because the most important telemetry feature of all is the precise display of the lap time. For that, it needs an extremely accurate signal to read the vehicle’s position. The GPS satellite signal wasn’t accurate enough for the AMG engineers, so they programmed a complex algorithm using acceleration data from the ESP, wheel rotation speed and steering angle sensors. Using that algorithm, the new Mercedes- AMG E 63 S 4MATIC+ can accurately determine its position within a few 'centimeters. The racetracks in the area are automatically shown to the driver, so that he simply has to select it. The data recording starts by itself when crossing the starting line. If the current racetrack is not on the display, the driver can enter custom tracks. When you initiate the track recording feature, the route you are following on this unknown race track is recorded as the ideal racing line and at the same time a corridor about 65 feet wide is created within which the ensuing laps are evaluated. IIn the overlay, you can display not only the lap time but also the speed, the lateral and longitudinal acceleration, steering angle, gas and brake pedal position, the current power and the torque values including rpm, the temperature of the engine and transmission, as well as all four tire pressures with the corresponding temperature. All told, there are more than 100 readings that are taken up to 100 times per second. To stay on top of this volume of data, AMG Track Pace is connected to all of the sensors via COMAND Online using fast FlexRay and CAN bus networks. Here the data transfer speeds can reach up to ten megabits per second. “But that’s not even close to all of it,” Wendlinger says, pleased, and unclips his iPhone from the holder on the windshield. “I filmed our ride and can now transfer the saved data from the car to the phone. The AMG Track Pace app then inserts the lap times, speed, rpm and accelerations, and overlays all of it live onto the video.” The entire movie can then be immediately shared on social media right from the app. “So that you can enter into a proper discussion about cornering with friends and competitors,” he laughs.
