Could the revised Mercedes S-Class be a car to help reduce global warming? A new engine with Blue Efficiency technology certainly points it in the right direction.

That engine is still a 3.0-litre V6 turbodiesel putting out 232bhp and 399lb ft of torque, but its now badged 350 CDI Blue Efficiency. Fuel economy rises to 37.2mpg with the standard-length car and 36.7mpg with the stretched version 9% improvements while CO2 emissions fall by 21g/km. Thats enough to cut company car tax liability by five and four bands respectively.

More safety kit

There are also safety upgrades from the latest E-Class monitors to detect a drowsy driver, unintended lane-changes or other cars in your blind spot plus automatic switching between high and low beam, and an improved night-vision camera. Some of it is standard and some optional, but in all there are Β£3300 worth of equipment additions for a price increase of just Β£300. The grille, lights and bumpers have also been reprofiled.

You still get the same peerless ride, sumptuous interior and magnificent refinement, plus far better performance and economy than youve a right to expect from a vast diesel limo. The new Jaguar XJ is going to have to be good and we mean very good to beat it. RS

Our verdict

The best luxury car you can buy is now even better
