Key Takeaways

• Magna launches DHD REX, a single-motor hybrid drive designed for range-extended electric vehicles (REEVs).
• The system supports three driving modes and offers a cost-effective solution for OEMs.
• DHD REX complements Magna’s existing DHD Duo hybrid system, targeting a broader range of vehicle segments.

Introduction of DHD REX

Magna, a leading automotive supplier, has unveiled the DHD REX, a single-motor dedicated hybrid drive tailored for range-extended electric vehicles (REEVs). This ready-to-integrate system features a modular architecture suitable for original equipment manufacturers (OEMs) facing varying regulatory constraints and customer demands in different markets.

Driving Modes and Design

The DHD REX operates in three distinct modes:

1. Pure electric driving
2. A generating mode where the internal combustion engine (ICE) charges the battery to extend the vehicle’s range
3. An optional parallel hybrid mode for enhanced performance on highways.

This single-motor configuration is designed to minimize costs and simplify packaging compared to traditional dual-motor setups. Magna has validated the system across vehicle segments B through E, including all-wheel-drive (AWD) layouts and SUVs, ensuring compatibility with both ICE-based platforms and battery electric vehicle (BEV) architectures.

In the context of REEVs, the combustion engine primarily serves as a generator under most conditions, with the electric motor responsible for vehicle propulsion. The optional parallel mode allows the ICE to provide mechanical drive at highway speeds, addressing efficiency losses inherent in the generator-to-motor energy conversion.

Complementing Existing Offerings

DHD REX supplements Magna’s DHD Duo, which features a dual e-motor dedicated hybrid solution currently in production. The single-motor setup aims to appeal to OEMs seeking range-extension capabilities without incurring the additional costs and complexities associated with a two-motor system. Its modular design effectively caters to both electrified ICE platforms and native BEV architectures.

Diba Ilunga, President of Magna Powertrain, emphasizes that the DHD REX exemplifies the company’s commitment to delivering adaptable and customer-focused solutions designed to meet diverse performance requirements across various markets.
