Sources: 8. Developments: 2. Horse Powertrain, a joint venture between Geely and Renault, has introduced new technologies specifically designed for off-road vehicle electrification. Initially, the venture announced the 3DHT200, a compact plug-in hybrid (PHEV) powertrain system. This system integrates 13 components into a single unit and features a three-speed hybrid transmission with two electric motors. It is capable of delivering 830 kW of total power and 4,920 Nm of wheel torque, intended to support navigation of inclines up to 45 degrees. The technology is set to debut in the Geely Galaxy Cruiser 700. Following this, the joint venture unveiled the B20, a 2.0-liter turbocharged gasoline engine. Designed for HEV, PHEV, and REEV configurations, the B20 utilizes the Miller cycle to achieve a thermal efficiency of up to 48.8%. To support demanding off-road conditions, the engine and its electrical components feature IPX8 certification, allowing for operation while submerged in up to 1.1 meters of water. ## Timeline ### 2026-09-11: Horse Powertrain unveils B20 off-road hybrid engine Horse Powertrain, a Renault and Geely joint venture, unveiled the B20, a 2.0L turbo hybrid engine featuring IPX8 certification for water immersion up to 1.1 meters. 3 sources. https://clstr.news/cluster/horse-powertrain-unveils-b20-off-road-hybrid-engine ### 2026-09-04: Geely and Renault develop high-torque PHEV system for off-road vehicles Geely and Renault's joint venture, Horse Powertrain, unveiled the 3DHT200 PHEV system for off-road SUVs, delivering up to 1,113 hp and 4,920 Nm of torque for the Geely Galaxy Cruiser 700. 5 sources. https://clstr.news/cluster/horse-powertrain-unveils-new-hybrid-system-for-off-road-vehicles --- Cite as: Horse Powertrain off-road hybrid technology development.
