Magna’s new 7-speed 7HDT300 dual-clutch 48-volt hybrid transmission made its debut earlier this year, in the launch of the European Jeep® Renegade and Compass e-Hybrid models. It was quickly additionally rolled out to Fiat 500X and Tipo Hybrid models. Now Stellantis and Magna have signed a multi-program agreement in recent days, that would allow the new transmission to be adopted in additional future Stellantis models.
“Our scalable transmission technologies aid our customers in their transition to vehicle electrification which help to achieve regulatory targets. The transmission enhances both efficiency and performance. We are excited that Stellantis has awarded Magna this hybrid transmissions business across multiple vehicle models, a testament to our expertise and capabilities,” said Tom Rucker, President Magna Powertrain.
The 7HDT300 hybrid transmission achieves stringent CO2 targets and offers improved driving dynamics due to electric torque vectoring and traction support.
The 7HDT300 dual-clutch transmission also provides a maximum torque of 320 Nm (236 lb.-ft.) and torque-split technology to optimize the efficiencies of the internal combustion engine (ICE) and the e-motor. The e-motor is capable of providing propulsion to the vehicle even when the ICE is switched off. This new transmission features independent on-demand cooling for the clutch and e-motor with a single oil circuit for cooling and lubrication, resulting in significant CO2 reductions in WLTC and real-world driving.
The Renegade and Compass e-Hybrid models offer up to 15% lower consumption and CO2 emissions than the previous gasoline models.
Currently, the 7HDT300 is being produced in Kechnec, Slovakia.
