From £60,595
The balance of performance and economy make it the pick of the S-class ranage

Our Verdict

The S-class is a benchmark in comfort and equipment. XJ is better to drive though

The Mercedes S-Class is a fine luxury car and a technological masterstroke. It is calm but rewarding

3 September 2010

What is it?

It’s the UK’s most popular S-class model by far, scooping up more than 80 per cent 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 new name.

Changes to the 3.0-litre common-rail diesel engine – including 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.

What’s it like?

The upshot is added off-the-line performance, even more impressive mid-range shove, relaxed cruising attributes and a level of mechanical refinement that encroaches on that of petrol S-class models.

Mercedes has also fitted its latest urea injection system. Concentrated within the catalytic converter, it turns up to 80 per cent of nitrogen oxides expelled by the engine into harmless nitrogen and water. A 25.7-litre tank for the urea solution is mounted in the spare wheel well and needs retopping every 15,500 miles.

The engine changes are backed by a revised seven-speed automatic gearbox with stop-start. It helps make the S350 Bluetec achieve a combined 41.5mpg and a CO2 rating of 177g/km. It also fires off shifts in a more determined way than before.

With the introduction of the S 350 Bluetec, Mercedes is rolling out a number of innovative new options, including Active Lane Keeping Assist and Active Blind Spot Assist.

Should I buy one?

It’s not exactly cheap, at £58,440, but the S 350 Bluetec’s balance of performance and economy continues to make it the pick of the standard S-class range.

This is such a well-rounded car; it's no wonder some people claim it is the best car in the world.

Based on Autocar's usual judgement of luxury cars, this should be the best car in the class (and possibly the world). However, unsurprisingly the criteria seemed to have 'changed' when they road tested the Jag XJ, allowing it to trump the Merc.

The new Jaguar XF 3.0D S is available in two states of tune: one with 237bhp (rivalling BMW’s 530d), or this, the 271bhp S version. It’s bang on 535d territory. Economy and CO2 output is 42mpg on the combined cycle and 179g/km, Mercedes engine doesnt sound that fantastic really, seeing as it need an additive to achieve figures comparable to the XF
