Tier 1 Magna has started production of its mild hybrid transmission for BMW Group. The new 7-speed, mild hybrid dual-clutch transmission is the latest to be featured exclusively on BMW Group’s compact class, which underpins all its front-transverse vehicles. The contract between Magna and BMW Group also includes production of mild hybrid transmissions for additional models, starting with the new BMW 2 Active Tourer.

“Our efficient hybrid dual-clutch transmission technology is an important step in achieving lower emissions and improved fuel efficiency,” said Tom Rucker, president of Magna Powertrain. “Leveraging Magna’s broad scalable product portfolio including hybrid transmissions and e-drives coupled with seamless powertrain system integration, we are ideally positioned to support customers including BMW Group in achieving critical CO2 emissions reduction goals.”

With its specific torque-split concept for hybridization, Magna’s 7HDT400 48V transmission is said to ensure optimal efficiency of an internal combustion engine and electric motor. It provides a maximum of 400Nm of torque as well as offering scalable functionality benefits. For example, the electric motor is fully integrated with the transmission, with the system featuring on demand cooling of the clutch and electric motor, with a single oil circuit for cooling and lubrication.

The transmissions are being built at Magna’s facilities in Neuenstein, Germany, and Kechnec, Slovakia.
