The 2.0-litre four-cylinder turbo engine boasts a spontaneous response to accelerator pedal commands, high tractive power (400 Nm max. torque from 3000 rpm), a supremely lively response and an engine sound typical of AMG. The crankcase made of high-strength, lightweight die-cast aluminium reduces the vehicle weight where it matters most for driving dynamics.
A twin-scroll turbocharger is used for turbocharging. It combines optimum responsiveness at low engine speeds with a strong power increase at higher speeds. The housing of the twin-scroll turbocharger is divided into two parallel ducts. Together with two separate exhaust ducts in the exhaust manifold, this makes it possible to channel the exhaust gases separately on the turbine wheel. This minimises the mutual negative influence of the individual cylinders in the charge change cycle. This reduces the exhaust backpressure and improves the charge change as well as the efficiency of the engine. The exhaust system features an automatically controlled exhaust flap as standard. Depending on the drive program selected the sound is modulated from balanced to powerful.
The AMG SPEEDSHIFT DCT 7G dual-clutch transmission also contributes to the agile and dynamic character of the new A 35 4MATIC Saloon. The gear ratios have been configured so that the driver experiences very spontaneous acceleration in all speed ranges, combined with fast shifting and optimum connections when shifting up.
