The new, top engine variant with 1991 cc is available as the A 250 BlueEFFICIENCY or A 250 Sport. In both cases the engine develops 155 kW (211 hp) and a maximum torque of 350 Nm from 1200 to 4000 rpm. Performance is at sports car level, with acceleration from zero to 100 km/h in 6.6 seconds and a top speed of 240 km/h. Nonetheless it has the best fuel consumption in this class at 6.1 l/100 km, and CO2 emissions of 143 g/km (A 250 BlueEFFICIENCY). Standing as much as 160 millimetres lower on the road than the preceding model, the new A-Class communicates design and dynamism at the very first glance. This radical form language, presented and enthusiastically acclaimed around the world with the Concept A-CLASS, was consistently implemented in the series production car. The appearance of the new A-Class reflects this new Mercedes-Benz design strategy. The result is what is known as a two-box design with a distinct character of its own, a sportily emotive exterior and an exceptionally high-quality feel to the interior. The A-Class is a five-seater model. The rears seats provide room for three passengers, despite looking like two individual seats with their sporty design. The boot volume is 341 litres, based on the VDA standard. If the rear seat backrests are folded down, its capacity jumps to 1157 litres. In all models the seat backrests feature a 60:40 split can be folded forward individually. The width of the luggage compartment between the wheel housings is 1050 mm. The basis for all three petrol engine variants in the new A-Class is the all-aluminium M 270 engine with two chain-driven overhead camshafts and four-valve technology. This power unit is extremely versatile, and will also be gradually introduced into larger model series. In this way it also contributes to a sustained reduction in production costs. The four-cylinder can be installed transversely (M 270) or longitudinally (M 274), and combined with front, rear or 4MATIC all-wheel drive, and also with a manual, automatic torque converter or dual clutch transmission. http://www.youcar.tv
