Mercedes-Benz S 250 CDI BlueEfficiency - First ever 4-cylinder S-Class

[JasM]

Rumours have surfaced that Mercedes plans to introduce their first four-cylinder S-Class. Being prepped for introduction at the Frankfurt Motor Show, the Mercedes-Benz S 250 CDI BlueEFFICIENCY will produce just 155 grams of CO2 per kilometer. This follows a trend being held by a number of automakers to make their largest sedans less polluting.

The S 250 CDI uses the same 2.1-liter diesel engine already found in the C-Class and E-Class and produces up to 224 horsepower with a maximum 500 Nm of torque. Performance figures have not been released, but we do know that the car will travel 100 km on about 5.9 liters of fuel. Although entry-level, the S 250 CDI produces only 11 hp less than the S 350, which uses a V6 CDI.

Cosseted around on an air of clattering ambivalence exhaling soot.

Give me a big balled V8 any day.

It's pretty much inevitable that this will happen, I expect it's gonna hit the SLK and E convertible too, for as long as Governments are gonna penalise manufacturers and consumers based on stupid CO2 numbers there'll be smaller engines. You can already get a 1.6 diesel Volvo V70.

Smaller engine = less mass in most cases which is another saving.

I hope it gets the 7 spd box though...

I can see this working well!
The reason I left the 4cyls engines some while ago was down to the 'taxi noises'.
Having had the V6 engine in E class, M Class and S class there is a big difference in the level of refinement shown by each.
The S is by far the best a hiding the fact that it is a diesel and as the 4 cyl has now been developed in to a much quieter engine, I'm sure it will be very acceptable.
The power and torque were never going to be issues...unless of course you want more! Then you chose a different variant.
