Featuring 48V mild hybrid technology, including a Belt-integrated Starter Generator and DC/DC converter. This tech provides ‘transient torque assistance reduce fuel consumption and CO2 emissions by enabling features like start-stop functionality and electric boost for the engine during acceleration’.
The HR12 LPG turbo engine is also the world’s first volume production unit to combine direct injection technology for use with Liquid Petroleum Gas (LPG) as well as gasoline.
The powertrain delivers peak power of 140PS (103kW) at 5,500rpm and peak torque of 230Nm starting from just 2,100rpm. When running on LPG it emits 9% less CO2 than using gasoline. Developed for both EU and global markets, the HR12 LPG fully complies with Euro 6e regulations, and is designed to comply with new Euro7 regulations.
Horse says the HR12 LPG benefits from a bespoke direct injection system that’s been developed specially for LPG use, an electronic vaporizer provides more accurate compression control, as well as reinforced valve-train components. The LPG fuel tank can be located below the boot floor in the vehicle’s spare wheel well, ensuring there is no compromise in interior packaging and practicality, the company maintains.
