Change down, change up a gear, short sharp burst of speed. Take a breather – only you have time to do that. The automatic transmission 9G-TRONIC available on the SL 400 and SL 500 leaves no second unused. It transmits the SL’s output quickly, precisely and without any interruptions to power. And so smoothly that you hardly notice it.

Dynamic Select.

At a touch of the DYNAMIC SELECT feature, drivers can choose between comfortable, sporty, particularly sporty and efficient driving styles, or their own individually defined style. Parameters such as the engine, transmission and steering characteristics are adjusted according to the selected transmission mode.

9G-TRONIC: the control centre for the highest of emotions.

The SL lives from the ease of bringing power playfully to the road. This is achieved in an especially elegant way with the automatic transmission 9G-TRONIC. With nine forward gears, the 9G-TRONIC enables efficiency, comfort and dynamism of an entirely new dimension. It is the world’s first nine-speed automatic transmission with a hydrodynamic torque converter in the premium segment. The wider gear spread allows a reduction in engine speed. The excellent driving performance thus remains unchanged while ride comfort is enhanced and noise levels are reduced.

The engine: performance for storms of enthusiasm.

The SL’s new-generation engines impress with their pulling power and refinement, unleashing intense feelings. The V6 petrol engine of the SL 400 generates an output of 270 kW (367 hp) and produces a maximum torque of 500 Nm – for powerful acceleration even at low engine speeds. The consistent lightweight construction, turbocharging, spray-guided direct injection with precise piezo injectors plus adjustable intake and outlet camshafts ensure less consumption and more output. The biturbocharging with inter-cooling offers huge reserves of torque. Effortless superiority at all times.
