Mercedes has revised its S-class range for 2010 with a few tweaks to the exterior including new day-running lights plus a revised 3.0-litre diesel that now comes in below 200g/km for CO2.

The start-point for the S-class range is now badged S350 CDI BlueEfficiency and comes with a 37.2mpg official fuel figure and will cost 110.7 pence a mile to run, according to KwikCarcost.

As with the pre-facelift car, the new S-class is one of the most stress-free motoring experiences you can buy, this side of a chauffeur. If you option it, the car will even come to a complete stop in heavy traffic when using the clever cruise control.

The engine and technology tweaks keep the car ahead of the competition and the S-class is still our choice in this sector.
