The new generation Mercedes A Class is one of the most successful models Daimler has launched in recent years. Now in a move to keep the momentum going, the Company  is adding two frugal BlueEFFICIENCY models to the range, including one diesel and one petrol.

The diesel version is less powerful, but as you’d expect much more fuel efficient, and therefore cleaner. The A 180 CDI BlueEFFICIENCY Edition needs only 3.6 liters of fuel per 100 km, and emits no more than 92 g/km CO2. But it only has 109 horsepower.

The A 180 BlueEFFICIENCY Edition petrol model offers 122 horsepower, and does 5.2 liter per 100 km – still pretty good. CO2 emissions for this one is 120 g/km.

Both models come with optimized aerodynamics compared to the standard A-Class to cut through the air more efficiently. They benefit from partial covering of the upper section of the radiator grille, aerodynamically shaped spring link coverings that improve the flow of air along the underbody at the rear axle, and a suspension that has been lowered by 15 millimetres.

Mercedes A Class BlueEFFICIENCY models will go on sale on 1 February 2013, while the first vehicles will reach customers in March 2013.
