Starting in autumn 2006, the diesel engine range available for the R-Class will be extended by a further six-cylinder engine, also equipped with third-generation common-rail direct injection. Besides the R 320 CDI 4MATIC (165 kW/224 hp), Mercedes-Benz will also be offering the new R 280 CDI 4MATIC, which has an output of 140 kW/190 hp. As a result, the R-Class can achieve a top speed of 210 km/h and accelerate from 0 to 100 km/h in only 9.8 seconds due to its powerful torque of 440 Nm (from 1400 to 2800 rpm). Combined fuel consumption is 9.3 litres per 100 kilo-metres, so that the new R 280 CDI 4MATIC can travel for more than 850 kilometres on a tankful of fuel.
In addition, the V6 diesel engine features a high-pressure pump (1600 bar), piezo injectors, and a variable nozzle turbine (VNT) turbocharger – thus ensuring low emissions and smooth operation. Standard equipment in the R 280 CDI 4MATIC also includes two oxidation-type catalytic converters and a maintenance-free particulate filter.
The six-cylinder unit is teamed up with the 7G-TRONIC seven-speed automatic transmission, which the driver operates electronically by means of the DIRECT SELECT lever on the steering column. The R 280 CDI 4MATIC is available exclusively with a 2980 millimetre wheelbase.
New AMG model with an output of 375 kW/510 hp
At the upper end of the R-Class engine range will be the new R 63 AMG 4MATIC, a 6.3-litre eight-cylinder engine with an output of 375 kW/510 hp and the kind of driving performance typically found in a sports car. The AMG model can accelerate from 0 to 100 km/h in only 5.0 seconds and has an electronically limited top speed of 250 km/h. The standard equipment for the R 63 AMG 4MATIC includes high-grade extras such as electronically adjustable AMG sports seats in front with multicontour function, nappa leather and seat heating at the front plus light-alloy wheels with SIZE 265/45 R 20 wide tyres, an AMG sports chassis based on AIRMATIC air suspension, and blue-tinted glass.
