Mercedes-Benz continues to upgrade its R-Class. Through the introduction of the new R 280 CDI 4MATIC und R 63 AMG 4MATIC models, which will become available this autumn, the touring SUV’s product range will be expanded to five engine variants. As a result, the output range of the six and eight-cylinder engines will extend from 140 kW/190 hp to 375 kW/510 hp. Furthermore, Mercedes-Benz will equip the R-Class with additional driver-support systems that will ensure even more driving comfort. Besides innovations such as the radar-based DISTRONIC proximity control system, the comfort-enhancing systems will include actively ventilated front seats, the LINGUATRONIC voice control system and a rear-view camera for safe and easy parking. The R-Class’s high level of long-distance comfort, which makes a significant contribution to driver-fitness safety, is documented by scientific studies conducted by DaimlerChrysler Research. The driver’s stress level as measured on the basis of the heart rate is significantly lower in the R-Class than in other comparable vehicles.
