Mandrid, Spain- HORSE Powertrain Solutions, a division of HORSE Powertrain Limited has started a production run of 1.2-litre, 3-cylinder turbocharged petrol engines for use in plug-in hybrid-electric vehicles (PHEVs).
The ‘HR12’ engine has the capacity to deliver peak power of 110kW (152PS) and maximum torque of 230Nm. The PHEV-optimized HR12 units will be produced at HORSE’s plant, Valladolid. Initially it is targeting production of 1,200 units per month. The HR12 PHEV variant will be first used upon the upcoming Renault Rafale E-Tech 4×4 Hybrid.
Mr. Patrice Haettel, Chief Executive Officer at HORSE, said, “This HR12 is the first plug-in hybrid engine manufactured at our Valladolid facility and the second produced by HORSE globally. This is a major landmark for our team, and proof of how HORSE’s internal combustion engine expertise can facilitate market-leading, low-emission mobility solutions. With outstanding range and efficiency, this PHEV architecture showcase the direction of the automotive industry and the value of HORSE’s indispensable technology leadership to our partners.”
Alongside the HR12 internal combustion engine, the complete powertrain unit will also feature three electric motors – two main, and one secondary:
- the first main electric motor on the front axle, delivering 50kW of power and 205Nm of torque
- the second main electric motor on the rear axle, delivering 100kW and 195Nm
- a secondary HSG (High-voltage Starter Generator) electric motor producing 25kW and 50Nm
Altogether, this will mean the PHEV’s maximum power output will be over 220kW (300hp), driven by a specially adapted and clutch less multi-mode gearbox. The PHEV’s energy will be stored in a 400-volt lithium-ion battery, with a total capacity of 22kWh.
The PHEV’s superior efficiency will mean that the new Rafale 4×4 will achieve superior emissions performance. In electric mode, it will achieve an average fuel consumption of just 0.7 litres per 100km, with CO2 emissions of only 15g/km.
