The new Mercedes-Benz A-Class - Intensive development work ensures exceptional acousticsMercedes-Benz A-Class: Schematic showing how the selective damping system for the new A-Class works.A-Class; The ESP hydraulic pump and control unit form a single compact entity.ESP can also monitor the tyre inflation pressure (option). The information appears on the central display in the instrument cluster.A-Class; The steering gear with electric motorOperating principle of the new electromechanical speed-sensitive power steering, part of the standard specification of the A-Class.Top: Sensor element of the Electronic Stability Program. Down: Hydraulic unit and control unit of Electronic Sability ProgramSchematic showing how the selective damping system for the new A-Class works.The selective damping system being offered in the new A-Class as standard equipment is celebrating its world premiere in automobile construction. The system consists of an additional valve casing in the shock absorbes which is used to adjust the damping level to match the specific driving conditions.The selective damping system being offered in the new A-Class as standard equipment is celebrating its world premiere in automobile construction.

In the cylinder head are two overhead camshafts, each of which controls two intake and two exhaust ports via roller cam followers. A chain drives the camshaft on the intake side, which is linked to its counterpart on the exhaust side.The petrol engines have been modified for the new A-Class. Output has been boosted by up to 38 percent compared to the outgoing modelsMercedes-Benz A 170 - Power Output GraphMercedes-Benz A 160 CDI - Power Output GraphMercedes-Benz A 150 - Power Output GraphMercedes-Benz A 200 - Power Output GraphMercedes-Benz A 180 CDI - Power Output GraphMercedes-Benz A 200 CDI - Power Output GraphThe new A-Class engines are based on a unique design which allows them to be installed at an angle of up to 59 degrees behind the front axle.Mercedes-Benz A 200 TURBO - Power Output GraphA-Class; The state-of-the-art, lightweight crank assembly in the petrol engines consists of an aluminium crankcase with cast-iron cylinder liners. Valve timing is taken care of by a hollow-bore camshaft made from induction-hardened forged steel and low-friction roller cam followers. A timing chain with a hydraulic tensioner and rubber-coated sprockets drives the camshaft. Hydraulic valve clearance compensation takes place automatically.The powerful A 200 TURBO engine develops 142 kW/193 hp.A-Class; The newly developed AUTOTRONIC works on the principle of a continuosly variable transmission.The newly developed diesel engines feature second-generation common-rail direct injection.New six-speed manual transmission for the models A 180 CDI, A 200 CDI and A 200 TURBO.The newly developed diesel engines feature second-generation common-rail direct injection.
