Fast, efficient new Mercedes C250 CDIBlueEfficiency C-class won’t stint on luxury
17 October 2008
Many manufacturers cut back on equipment and luxury when producing ‘green’ versions of their cars. Not Mercedes-Benz.
This week the German carmaker unveiled a new ‘BlueEfficiency’ C-class, the C250 CDI. It uses an all-new 2.2-litre turbodiesel engine, which claims official fuel economy of 54.3mpg, while emitting just 138g/km CO2.
This is despite the C250 CDI being based on Mercedes’ high-level ‘Avantgarde’ spec, and loaded with equipment.
However, what makes this new Mercedes doubly impressive is that it’s no slouch in the performance department, either.
It use twin sequential turbos – which means a small high-pressure turbo provides the initial throttle response, gradually handing over to a larger low-pressure turbo as the revs build – and the latest common rail direct injection technology.
And the result is a power output of 201bhp and an enormous amount of pulling power - and all in a so-called eco model. Top speed is 155mph and the 0-62mph sprint takes 7.0 seconds.
Other green tweaks
Other BlueEfficiency modifications include low-rolling resistance (their lower friction should improve fuel economy), longer gearing, improved aerodynamics, more accurate fuel consumption information, and a gearshift indicator - all becoming commonplace on the latest .
Initially available in Europe only in a limited run of 5,000 ‘Prime Editions’, the C250 CDI arrives in the UK next year. Expect to pay around £32,000.
Lower powered and even more economical versions of the new engine will then follow, and make their way into other Mercedes models.
