Mercedes-Benz models, news & reviews

Mercedes has been a little slow off the mark with its environmental campaign, but hopes it range of new BlueEfficiency cars – spearheaded by the C180K BlueEfficiency on test here – will do for emissions, economy and public perceptions what EfficientDynamics has done for BMW. And there’s no price penalty for opting for the BlueEfficiency model – in fact at £22,585 it’s actually £815 cheaper than the standard C180K model it replaces (although that includes the recent 2.5% VAT cut).
BlueEfficiency is the umbrella term Mercedes uses to describe the optimization of aerodynamics, use of lower rolling resistance tyres, lightweight design and energy management to cut fuel consumption and slash emissions.
Rather than roll out a set number of eco-initiatives across its range, each class gets a set of bespoke BlueEfficiency measures that suits it best. So the C180 K gets a thinner windscreen, lighter but more effective noise insulation material, lightweight forged alloy wheels for a 32kg weight reduction, bespoke Michelin tyres with 17% less rolling resistance and a intelligent energy management system.
There's also a number of body tweaks - smaller exterior mirrors, complete with LED arrow-shaped indicator lenses, a smooth underbody, enhanced panel seals, lowered suspension and a partially blanked grille – for slipperier aerodynamics. Oh, and lighter, smaller 1.6-litre engine…
It’s no tyre-smoker, but if no one told you, you’d never know that there was such a small powerplant under the bonnet. That’s because despite the 200cc drop in capacity, performance - 156bhp at 5200rpm and 170lb ft at 3000rpm – remains unchanged but now with significantly better economy and emission levels. With a useful 170lb ft of torque kicking in at 3000rpm – bang on the nose for powering past middle-lane dawdlers on the motorway – performance is brisker than you’d expect given the engine’s modest size and outputs.

What's next for Christ's sake? 1.2 3-cyl turbo which still will be sold as 180Kompresor, but will go under 100g/km?

I got my figures from mercedez-benz.de as the weights seem to be missing from the UK web site. Perhaps the UK version is de-contented in some other way...

Comment8 - Odd, as my figures from Mercedes show a 32kg drop in weight.
Tony - I think one line that mentions public perception hardly qualifies as 'crowing on about the relevance of image', does it? I've looked at some weights - a BMW 320i weighs in 1445kg, the Merc I tested weighs 1485. Some way off the 100kg you mention. But good point well made about the transmissions - Mercedes should have its seven-speed automatic as an option on all its models...

BTW Ben, Mercedes are claiming a 10kg weight saving over the 200K....
