Unveiled at the 2009 Franfurt Motor Show, the Kangoo Z.E. Concept presents Renault's vision for a future electric vehicle targeted to urban environments and focused on minimizing energy consumption while offering good levels of comfort and practicality.
It is powered by a 70kW electric motor which delivers 226Nm of torque, in conjunction with a lithium-ion battery.
The car range is 160 km, while the top speed is electronically limited to 130 km/h.
Energy consumption is minimized thanks to many energy optimization solutions, such as the advanced climate control system, aerodynamic design, heat-reflective paint, thermal insulation panels.
The battery recharging operation can be operated in two ways: a standard charge takes between four and eight hours, via a charging socket situated on the outside of the vehicle, while a quick charge takes just 20 minutes and uses the same socket at bespoke charge stations.
The conventional drag-producing exterior mirrors have been replaced by streamlined, low-energy cameras which are powered by the roof-mounted solar panels.
These cameras provide improved all- round visibility, which is especially practical when manoeuvring. The full-disc aluminium alloy wheels produce less drag, too, while the headlights use light-emitting diodes (LEDs) which are not only long- lasting but also low consumers of energy.
A linear display on the outside of the door provides an indication of how much range remains even before the driver gets inside the vehicle. This lit display can be likened to the charge indicator of a cell phone.
The use of heat-reflective paint and bodywork featuring large surface areas reduces temperature fluctuations.
Indeed, the bodywork functions along the same lines as a Thermos flask and comprises two insulating panels with a sandwich of air in between.
Thermal insulation is further optimized thanks to specialtreatment of the glazed surfaces, meaning that less call is made of the climate control and heating systems which are big consumers of energy.
Solar panels positioned on the roof are employed to power a temperature regulation system inside the car. Keeping the cabin cool uses a significant amount of energy, but this system also permits a pleasant temperature to be maintained inside the cabin, even at a standstill or when parking, and avoids having to put the climate control system on boost when first getting in the car on a hot day.
