The joint venture between Geely and Renault, Horse Powertrain, has unveiled the W40, a 4-liter V8 twin-turbo HYBErid engine capable of producing a maximum output of 670 horsepower.

The powertrain specialist established jointly by Geely and Renault is drawing global attention as it moves to fully integrate high-performance internal combustion engines with electrification technology. The newly announced engine adopts a vertical configuration and features a hot-V layout, which places the turbocharger between the two cylinder banks to significantly shorten the intake path. Designed to weigh 200 kg, the engine achieves both top-tier lightweight performance and high power output in its class.

The W40 engine delivers a maximum output of 500 kW, or 670 horsepower, and a peak torque of 800 Nm. It is paired with the 8LDCT, an 8-speed wet dual-clutch transmission developed in tandem. Equipped with a silicon carbide control system and a variable-displacement mechanical pump, the transmission can stably handle torque inputs of up to 1,050 Nm. It also achieves prefill times of less than 50 ms and shift response speeds of under 20 ms. This powertrain is scheduled to be installed for the first time in Type 135, a next-generation sports car project currently being developed by Lotus, a sports car brand under Geely.

Lotus has recently shifted from a pure electric vehicle-exclusive strategy to a flexible electrification diversification strategy, accelerating the development of HYBErid models. The new sports car, targeted for release in 2028, is reported to deliver overwhelming performance with a combined system maximum output exceeding 1,000 horsepower. The company plans to strictly keep the vehicle's curb weight below 1.8 tons to realize Lotus's signature refined and agile driving performance. Through the unveiling of this V8 HYBErid powertrain, Geely, Renault, and Lotus have revealed new possibilities in the high-performance sports car market.
