S-class hybrid just doesn't cut the same mustard as its more powerful siblings
With the S300 BlueTEC Hybrid, a four-cylinder diesel engine is being offered to S-class buyers in the UK for the first time. The 2.1-litre four-cylinder diesel engine in the new model was offered in the S250 in the previous-gen S-class, a car that never made it to these shores.Now it’s back in the new line-up, armed with hybrid assistance, to produce some deeply impressive numbers, and a place on UK price lists.The CO2 figure of 115g/km and combined fuel economy of 64.2mpg seem almost implausibly low for a car of the S-class’s size and weight and more akin to that of an efficient family hatchback; but the boffins at Mercedes reckon a real-world figure of even 70mpg might be possible — should you have the most feather-like of right foots. Crikey.
