New Mercedes A Class: A 180 BlueEFFICIENCY Edition models launch

Mercedes are launching two new eco versions of the new A Class – the A 180 CDI BlueEFFICIENCY Edition and A 180 BlueEFFICIENCY Edition. Mercedes has had a play with the aerodynamics on the new A Class to lower the Cd value from an already very low 0.27 to 0.26 by partially covering the upper section of the radiator grill, adding aerodynamically shaped spring link coverings that improve the flow of air along the underbody at the rear axle and lowering the suspension by 15mm. Mercedes has also tweaked the generator management for more efficiency and had a play with the gearbox to make the ratios longer (which will help economy, but won’t do much for responsiveness).

The Volt is a landmark model – a hybrid electric car that can run for 40 miles on battery power alone or use the onboard 1.4 petrol engine for further charge. The new Volt will also be one of the world's first plug-in hybrids when it goes on sale in 2010 (2012 for Europe), allowing it to be hooked into the mains to top up the battery.
