Mercedes S250 CDi BlueEfficiency coming?

Now this is an area that hasn’t really got a handle on the whole ‘Eco’ thing yet – big, luxury saloons. But if rumours that have started popping up today are to be believed, Mercedes is going to introduce an S250 BlueEfficiency at the Frankfurt Motor Show next month. A 4-pot S Class. Whatever next? A diesel Porsche?!

I suppose it was inevitable that an ultra economical S Class was going to be on the cards. Mercedes has already started to play the game with the new S400 Hybrid, and BMW is bringing the new ActiveHybrid 7 Series to Frankfurt. But this is a step even further in the quest to get big, luxury saloons super-economical.

But how bad will it be – a four pot S Class? Actually, not that bad at all. The S250 will probably utilise the blown 2.1 litre 4-pot already seen in the E Class BlueEfficiency. That engine emits just 154g/km CO2 and manages to return 47mpg. Not only that, but it manages to get to 60mph in 8seconds and has a huge wodge of torque – 369lb/ft – which makes it very responsive.

As we said, just a rumour at the moment. But one that makes a lot of sense in the current climate. It would have been unthinkable even just a few years ago, but times change.

And I’m pretty sure that every chauffeur company in the UK will be queueing up to order a de-badged S250 BluEfficiency.
