The French carmaker has revealed its new R110 electric motor fort he 2018 model its Zoe, Europe’s best-selling electric vehicle. Despite being the same size as ist predecessor R90, the R110 offers 12kW (16hp) more power. The new motor shaves almost two seconds off ZOE’s 80-to-120kph time. At lower speeds and in urban areas, the R110 packs the same punch as the R90 from which it is derived thanks to the peak torque of 225Nm.

The R110 motor is the latest fruit of Renault’s electric motor development and production strategy. The all-Renault R110 – an evolution of the R90, developed in just two years – is made in France at the company‘s Cléon plant in Normandy. It has been designed by engineers working out of the Renault Technocentre, southwest of Paris. In addition, the R110 packs a combination of electrical machine- and power electronics-related innovations that have yielded an extra 12kW with no increase in either weight or volume. 

The introduction of the R110 takes the number of variants of the Renault motor available for Kangoo Z.E., Master Z.E., ZOE and Daimler’s Electric Drive Smart to five (44kW, 57 kW, 60 kW, 68 kW and 80 kW).

The R110 motor will be certified in accordance with the new Worldwide Harmonized Light Vehicles Test Procedure (WLTP) which has been gradually rolled out in Europe since September 1, 2017, to replace the NEDC certification. The new, more severe procedure is intended to mirror real-word vehicle use more accurately and, in the case of electric vehicles, measures driving range, expressed in kilometres. The WLTP cycle, which involves dynamometer testing, is longer and involves a higher number of phases. Speeds are also higher and acceleration is harder. Certified ranges are consequently lower and more in-line with real-world figures. The new procedure does not alter ZOE’s real-word range which stands at 300 kilometres in urban and peri-urban areas. WLTP certification of the R110 motor is in progress. Early estimations based on the new WLTP protocol (approximately 300km) support the real-world range figure.
