The vehicle is equipped with an electronically controlled dual-clutch gearbox (S tronic). Torque between the engine and the gearbox is transmitted via two independent clutches. They enable smooth, uninterrupted acceleration of the vehicle.
The gears are shifted up or down automatically according to preset gearshift programmes.
When you drive at moderate speeds the gearbox will select the most economical shift programme. It will then change up early and delay the downshifts to give better fuel economy.
