The Elect'Road is a plug-in series hybrid version of Renault's popular Kangoo. Sales began in Europe in 2003, mainly in France, Norway and a few in the UK. The Elect'Road was sold alongside Renault's Electri'cité electric-drive Kangoo battery electric van. Renault discontinued the Elect'Road after selling about 500, primarily in France, Norway and the UK, for about €25,000.
The Elect'Road had a range using a nickel-cadmium battery pack and a liquid-cooled gasoline "range-extender" engine.
Although the Elect'road had a range extender it is effectively the very first plug-in hybrid electric vehicle (PHEV). In hybrid terms it operates in a blended mode, using engine and battery power simultaneously.
Passenger compartment heat is powered by the battery pack as well as an auxiliary coolant circuit that is heated by the range extender engine.
