Transmission general data
In the fall of 2010, engineers of Mercedes-Benz presented an updated version of the automatic gearbox 7G-Tronic Plus. For the first time this gearbox was applied in the CL-class (216 series). According to representatives of the company, this gearbox became more comfortable, quick-operating and economical than its predecessor. The 724.2 gearbox is equipped with the torque converter of a new generation. This torque converter is more durable; it has reduced noise level and faster response time thanks to innovative technology. In addition, this gearbox is equipped with the “start-stop” system. The engine RPM gets reduced in the ECO mode that significantly contributes to fuel economy.

The 724.2 gearbox undergone systematic optimizations to reduce energy losses caused by traction. This and other measures made it possible achieve 7% fuel economy. In 2012 a new car Mercedes-Benz SL was equipped with the 7G-Tronic Plus. The roadster became the first car of Mercedes-Benz, which was equipped with a newly developed Direct Select paddle shifter on the centre console. This feature is used for more dynamic driving style. The latest changes in 7G-Tronic Plus were introduced in 2013. The updated version of this gearbox was used in E300 BlueTEC HYBRID, where the 20 kW e-motor was integrated in the case of the torque converter. In 2013 the 7G-Tronic was replaced by the 9G-Tronic automatic gearbox.
Peculiarities:
- 7-forward gears: increased difference between gear ratios of lowest and highest gears, while maintaining small intervals between gear ratios in other gears, increases driving comfort.
- Optimal engine RPM contributed to low fuel consumption and smooth gear shifting.
- Solid power reserve: fast accelerations became possible thanks to reverse gear shifting with omitting of several gears;
- New generation torque converter: reduced wear, lower noise level and better responsiveness thanks to innovative technology.
- Reduced fuel consumption: the function “Start-Stop ECO” ensures that the engine switches off temporarily when the car gets stick in traffic jams of stops at traffic lights.
- Comfort and sportiness: drivers can choose from 3 operation modes: «E» (Economy) – to reduce fuel consumption, «S» (Sport) – for sporty driving style, «М» (Manual) – for rapid gear shifting with the help of paddle shifters.
