After the S-Class had been on sale in the UK for six years, Mercedes offered an impressively wide range of engines, though the hybrid and four-cylinder diesel was not on the UK lists and the 250 four-cylinder diesel had been dropped by 2012.
The V6 petrol engine is good for 302bhp and can take this big car from 0-62mph in just 6.9secs. Thanks to the addition of Mercedes’ BlueEfficiency technology, this engine is also promising an official combined figure of 37.2mpg, a very impressive mix of performance and economy.
The S 500 has a 4.6-litre V8 and 429bhp and still offers 30mpg combined, so there’s little point in the 510bhp 5.5-litre V12 and its near-supercar 4.6sec 0-6omph sprint time. It can only return a combined 20mpg. Quite simply, the S600 and the two AMG models are exceptionally rapid.
However, it is the 350 CDI, which is the UK’s most popular S-Class model by far, scooping up more than 80 percent of sales. And Mercedes-Benz is now giving buyers further reason to choose the S 350 CDI, or S 350 Bluetec, to give it its full name.
Changes to the previous-generation 3.0-litre common-rail diesel engine included improved injection efficiency, added turbocharger boost pressure and reduced compression ratio – boost power by 22bhp at 254bhp. Torque rises by 59lb ft to 457lb ft, developed at 1600rpm, as before.
