Even when driven sedately, the Mercedes R-Class won’t stretch a gallon of diesel to more than 35 miles and, if used at all enthusiastically or around town, it’ll knock 10mpg off that with ease. An 80-litre fuel tank does at least mean a range of over 400 miles.
Prices for the two-car range start from £43,755 for the entry-level, 187bhp R 300 CDI and rise to £47,910 for the stretched 350 CDI, which boasts an extra 74bhp at 261bhp.
Depreciation is concerning. According to the WhatCar? depreciation calculator, the entry-level car will retain just 35 percent of its original value after three years and 36,000 miles, with three-year servicing costs coming in at £1777. The 350 CDI’s three-year retained value is slightly stronger at 38 percent.
Standard equipment across the board is extensive and includes climate and cruise control, full electrics, leather and parking sensors. Mercedes’ rear seat entertainment will set you back an eye-watering £1725, and if you want an electric sunroof, that’ll be another £915.
