New 2.2-litre engine makes S-class 'first luxury car to dip under 150g/km'
1 October 2010

Mercedes has revealed its new S250 CDI BlueEfficiency, which the company claims is the most fuel-efficient production luxury car, at the Paris motor show.

It achieves a fuel economy of 48mpg on the combined cycle and emits 149g/km of CO2, which Mercedes claims makes it the first in its class to dip under the 150g/km mark.

It is the first S-class to be given a four-cylinder diesel in the model’s 60-year history.

The 2.2-litre unit mated G-Tronic Plus 7-speed automatic transmission gives 201bhp and 369lb ft of torque at 1600rpm.

It will power the S250CDI from 0-60 in 8.2 seconds and a top speed of 149mph.

This is made possible by the standard-fit ECO stop-start technology and high torque at low engine speeds achieved through two-stage turbocharging – from one high-pressure and one low-pressure turbocharger.

The new engine is part of a new range of four new petrol and diesel engines for the S-class. The other diesel, in the S350 BlueTEC, is a V6 which delivers 255bhp and emits 177 g/km of CO2.

Thats still impressive performance, more than adequate for most peoples needs I would have thought. I cant wait to own one! (in 15 years time lol)

currently a happy owner of a Mitsubishi Shogun Pinin :)

Surely the relatively small difference between this and the V6 350 diesel means this will only be of interest to the luxury taxi market. Its not as if saving a couple of quid on fuel will mean much to anyone who can afford an S class is it. Its still impressive for a thing of its size and weight though

So basically, because of emissions regs and all the other laws that are governing the industry, cars that are supposed to be desirable and rare, are just going to become mass market 3 series and C class, because BMW will no doubt follow suit sometime soon. Although I must say I do hope that it just follows the Audi A8 2.8 FSI and never really truly takes off. Besides 8.2secs yes thats reasonably impressive but in a car like that you want to beat people in a 120d or 170bhp A3 2.0tdi?

Herewith the new bestseller in the range .

Those figures are more than "adequate " for me . However EU 6 is likely to price diesels off the market so advancing petrol tech is just as important

Audi offers a detuned 3.0tdi in its new A8, with 2 wheel drive and similar mpg to this, but it's still a 6 cylinder engine, and probably the nicest sounding (diesel) one around.

Why can't Mercedes achieve 45+ mpg with a 6 cylinder diesel ?

If I cared enough about fuel consumption to buy the S250CDI, surely I'd settle for an E-class anyway ?

But, yes, I'm sure it will still sell.......

in a car like that you don't race, unless you're ....... well finish for yourselves.. great car for it's purpose

Impressive figures but a car like this should be able to waft along. I bet this has to be foot to the floor to achieve anything like reasonably 'real world' performance figures.

Only luxury taxi firms need apply.

30 September 2010

Pretty sure the enormous torque will be enough to give it 'real world' performance. Also don't forget that there are some countries with, outlawed, laws which tax cars on their engine capacity. This car would be perfect for such markets.

30 September 2010

Nearly exactly the same power and performance figures as the original S320 cdi, not bad!

[quote orandzh]n a car like that you don't race, unless you're ..[/quote][quote orandzh]great car for it's purpose[/quote] I agree in those terms, however with a smaller capacity S Class which is incredibly desirable mid level business men who still have a competitive streak will want to beat off others in the "lesser" cars. I have been reasonably fortunate, however my much older parents still race people away from their traffic lights..fortunately in real world terms not a lot will beat a 535d but the point stands...people in this type of car will still race. They want to show kids in clio's or hot shots in A3's and 1 series that they are boss.
