The new form of turbocharging guarantees spontaneous throttle response and ensures a more dynamic driving experience while increasing the efficiency. In addition, the electrification of the turbocharger enables higher torque at low revs which also increases the agility and optimizes the acceleration from a standstill.

The new turbocharger is operated via a 48-volt on-board electrical system which works at speeds of upto 170,000 rpm and enables a very high airflow rate. The innovative technology in the SL 43 in combination with the M139 two litre in-line four-cylinder engine produces an output power of 381 hp at 6750 rpm and 480 Nm of torque available between 3250 rpm and 5000 rpm.

The new SL 43 accelerates from 0-100km/h in 4.9 seconds and the top speed is set at 275 km/h. In addition, the second-generation RSG also functions as a mild hybrid in the 48-volt on board electrical system which also increases the comfort of the vehicle.

The M139 four-cylinder engine in the SL 43 has been combined with the AMG Speedshift MCT 9G transmission (Multi Clutch Transmission) for the first time. This helps in reducing the overall weight and optimizes the response to the accelerator pedal.
