Mercedes R-Class

Mercedes first venture into the MPV market wasn't a great success. The original R-Class sold 75% fewer units than the 50,000 it expected but now these spy shots show the German firm are going to try again.

This prototype R-Class mule was spotted with a disguised front end that is expected to receive a B-Class style re-design. At the rear there will be only a few minor updates including new tail lights, exhaust pipes and an updated bumper.

A range of existing engines with power outputs from 190hp to 306hp will all make a return to the R-Class along with the addition of a BlueEFFICIENCY eco engine. The most likely candidate is the 2.2-litre four-cylinder diesel engine from the C250 CDI which produces 201bhp but emits just 138g/km of CO2.

Not even the unsuccessful sales of the first R-Class were enough to dissuade Mercedes from trying again; they seem committed to making this MPV a success and obviously see it as playing a part in the future of the brand. What part that is remains to be seen, but all will be revealed when the updated car is officially revealed at the Geneva Motor Show in March.
