Magna, one of the world’s largest automotive suppliers, has introduced DHD REX, a single-motor dedicated hybrid drive for range extended electric vehicles (REEVs). The ready-to-integrate system is built on a modular architecture designed for OEMs operating across markets with different regulatory requirements, infrastructure conditions and customer expectations.
DHD REX runs in three modes: pure electric driving, a generating mode in which the ICE charges the battery for range extension, and an optional parallel hybrid mode for highway performance. The single-motor design reduces cost and packaging complexity compared to dual-motor configurations. Magna says the system is validated across B through E vehicle segments in AWD layouts including SUVs, and integrates into both ICE-based platforms and BEV-derived architectures.
In a range extended EV, the combustion engine runs as a generator in most conditions rather than driving the wheels—the electric motor handles propulsion. DHD REX’s optional parallel mode adds the ability for the ICE to contribute mechanical drive at highway speeds, where the efficiency penalty of the generator-motor conversion path is most pronounced.
DHD REX complements Magna’s DHD Duo, a dual e-motor dedicated hybrid already in series production. The single-motor architecture targets OEMs that want range extension capability without the cost and packaging of a two-motor system, and the modular design adapts to both ICE-based platforms being electrified and native BEV architectures adding a range extender.
“DHD REX reflects our commitment to adaptable, customer-focused solutions that support a wide range of performance and market expectations,” said Diba Ilunga, President Magna Powertrain.
