Mercedes-Benz A-Class and B-Class receive all-wheel drive variants

Article by Christian Andrei, on November 24, 2013

The A-class and B-class Mercedes-Benz range is now broader with the addition of new 'ECO SE' and all-wheel-drive variants that offer impressive fuel economy. The new ECO SE economy models will replace the A180 CDI SE and B180 CDI SE manual variants. Mercedes claims that the A180 CDI ECO SE has an average of 78.5mpg and CO2 emissions of 92g/km.

Meanwhile, the outgoing model returns 74.3mpg and emits 98g/km of CO2. The same improvements were applied to the Mercedes B180 CDI ECO SE, with 74.3mpg and 98g/km of CO2. Meanwhile, the outgoing model returns 68.9mpg and emits 108g/km of CO2. As a result, both are now free to tax, as opposed to only the A-class.

They also benefit from low company car tax bands. Set to become available in January 2014, the ECO SE models received aerodynamic enhancements, some weight-saving measures and powertrain modifications so that it will become more efficient without sacrificing performance. Mercedes said that the power, torque, top speed and acceleration figures of both models are unchanged.

The range will also have new '4MATIC' all-wheel-drive editions of the A-class and B-class. In addition, this system will be available on A250 models, in AMG Sport and Engineered by AMG trims, and on the B220 exclusively in Sport trim. The system, which was introduced in the Mercedes-Benz CLA, sends torque between the front and rear axles through an electro-hydraulically controlled multi-disc clutch unit.

It operates automatically and, when needed, it can distribute up to 50% of the power to the rear wheels. The new Mercedes A180 CDI ECO SE and B180 CDI ECO SE have starting prices of £21,965 and £22,950 respectively. Meanwhile, the all-wheel-drive versions of the A250 4MATIC have a starting price of £28,985. Meanwhile, the B220 4MATIC is priced from £28,135.

Press Release


With the introduction of all-new ECO models, the A 180 CDI ECO SE and B 180 CDI ECO SE, Mercedes-Benz UK now offers even better economy, with CO2 emissions from just 92 g/km.

The ECO SE vehicles, available from January 2014 production, both feature weight-saving measures, powertrain refinements, improved fuel consumption with no impact on performance, and improved aerodynamics, with the A 180 CDI ECO SE offering a class-leading coefficient drag of 0.26.

These practical changes include the use of an aerodynamic grille element, coupled with underbody panelling and lowered suspension (-10 mm front and 15 mm rear for A-Class, and 20 mm at the front and 15 mm at the rear for B-Class).

Both vehicles feature manual transmissions with longer ratios in the higher gears, an improved energy recuperation system and make use of a lightweight fuel tank to save on weight.

Replacing the current A 180 CDI SE and B 180 CDI SE manual variants, CO2 emissions on the A 180 CDI ECO SE have been reduced by six per cent to 92 g/km, with combined fuel consumption increased to 78.5 mpg, compared with 74.3 mpg on the outgoing model. B 180 CDI ECO SE emissions have also reduced to 98 g/km CO2, a reduction of nine per cent, with the combined mpg increasing by eight per cent to 74.3 mpg. Despite the focus on economy, for both models the power, torque, top speed and 0-60 mph acceleration, remains unchanged.

Both vehicles are free from road tax and the Benefit In Kind company car tax band for the A-Class is just 13 per cent, with qualification for 100 per cent capital allowance until 2015.

In addition to the new ECO SE models, the advanced four-wheel drive system first seen on the CLA 250 4MATIC, comes also comes to the A- and B-Class from January 2014.

4MATIC all-wheel drive ensures optimum traction and driving dynamics in all road conditions, with torque ideally distributed between front and rear axles by an electro-hydraulically controlled multi-disc clutch with variable torque distribution, which allows as much as 50 per cent of power to be sent to the rear wheels.

The A 250 4MATIC is available in both AMG Sport and Engineered by AMG trim, with the B 220 CDI 4MATIC exclusively in Sport trim.

The A 180 CDI ECO SE is priced from £21,965 on the road, with the B 180 CDI ECO SE from £22,950 OTR. The A 250 4MATIC is available from £28,985 OTR for the AMG Sport trim and £30,905 for the Engineered by AMG trim, whilst the B 220 CDI 4MATIC stars at £28,135 OTR.
