Summary: Magna has introduced DHD REX, a dedicated hybrid drive for range-extended electric vehicles built on a single-motor architecture. The modular system supports electric driving, a generating mode for range extension, and an optional parallel hybrid mode, and is designed to scale from B- through E-segment vehicles including SUVs in all-wheel-drive layouts.
Key engineering takeaway: DHD REX uses a single e-motor in a multi-mode configuration — pure electric, series generating and optional parallel hybrid — to cover the full range of REEV operating conditions while reducing component count and packaging complexity compared with dual-motor architectures like Magna’s own DHD Duo. The parallel mode option is notable, as it allows direct mechanical drive at highway speeds where series architectures typically suffer efficiency losses through double energy conversion.
Why it matters: Range-extended EVs are gaining renewed OEM interest as a way to deliver electric driving characteristics without full dependence on charging infrastructure, particularly in markets where network coverage remains uneven. A ready-to-integrate, segment-scalable solution from a major Tier 1 lowers the barrier for OEMs looking to add REEVs to their portfolio without committing to full in-house powertrain development.
Magna introduces dedicated hybrid drive for REEVs
Magna is expanding its dedicated hybrid portfolio with the introduction of DHD REX, a dedicated hybrid drive for range extended electric vehicles (REEVs) engineered to deliver an electric-like driving experience with instant torque response, smooth and quiet operation, and seamless range extension. The ready-to-integrate system is built on a modular, single‑motor architecture that enables automakers to adapt the solution to meet diverse regulatory, infrastructure, and customer requirements across global markets.
As electrification continues to evolve globally, OEMs are increasingly challenged to balance electric-vehicle performance with the need for greater versatility. DHD REX aims to address this need with a proven multi-mode design supporting electric driving, generating mode, and an optional parallel hybrid mode, expanding range capability while maintaining consistent drivability.
“Magna’s approach to electrification is centered on giving our customers flexible pathways forward,” said Diba Ilunga, President Magna Powertrain. “DHD REX reflects our commitment to adaptable, customer‑focused solutions that support a wide range of performance and market expectations.”
A complementary solution to Magna’s DHD Duo, the company’s dual e-motor dedicated hybrid drive already in series production, DHD REX is engineered from the ground up to deliver scalable efficiency and integration flexibility for OEMs operating in diverse regions. Its single-motor packaging reduces system cost and complexity, while enabling smoother, more predictable vehicle behavior across all driving scenarios.
Building on this foundation, DHD REX delivers a set of core technical capabilities that support a wide range of global use cases:
- Architecture & Efficiency – Reduces size, weight, and system cost while delivering validated efficiency
- Operating Modes – Electric driving, generating mode for efficient range extension, and optional parallel hybrid mode for improved highway performance
- Scalability & Application – Applicable to B through E segments in AWD layouts, including SUVs, and adaptable to varying regional regulatory demands
- Integration Benefits – Modular, compact design simplifies packaging and supports easier adaptation across both ICE-based and BEV platforms
