Mild hybrid transmissions for compact front-wheel drive BMWs are ready

The range of BMW it will be more and more electrified. In particular, many models have chosen and will choose the solution mild hybrid which is characterized by the presence of a small electric unit to support the heat engine.

In combination with these powertrains, Magna is preparing the 7-speed double clutch transmissions which will be equipped with the next compact BMW.

An aid for emissions and performance

The dual-clutch automatic transmission called 7HDT 400 48V will be featured on all upcoming front-wheel drive mild hybrid models. The first BMW ever to receive the new transmission will be the Serie 2 Active Tourerrecently renovated with the debut of the second generation.

According to Magna, the gearbox has been developed to make an important contribution in terms of performance and containment of fuel consumption and CO emissions.2. The transmission will manage up to 400 Nm of torque and will be built in the Neuenstein, Germany, and Kechnec, Slovakia plants.

BMWs with a double clutch

Specifically, the new transmission should be combined with the mild hybrid petrol versions 220i e 223i of the BMW 2 Series Active Tourer, which deliver 170 and 204 hp respectively.

In the future, this same solution could be adopted by the restyling of the 1 Series, the new X1, the new X2 and a possible restyling of the 2 Series Gran Coupé. Since the gearbox will support a maximum torque of 400 Nm, we deduce that the more powerful and all-wheel drive versions of the BMWs will retain the current combination with the8-speed automatic.

This is the case of the M135i xDrivefrom the M235i xDrive and the future X1 M35i (probably also equipped with four-wheel drive), all equipped with the same 2-liter turbo with 306 hp and 450 Nm. These values, however, could still grow with the debut of restyling and new models.
