Renault Kangoo Z.E. Concept

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.


Renault Kangoo ZE ConceptKangoo Z.E. Concept is based on the Renault Kangoo model and aims at bringing zero-emission mobility to the business road-user.

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.

Exterior Design

Renault Kangoo ZE ConceptKangoo Z.E. Concept’s dimensions (length 3.95m, height: 1.85m) ensure that it is perfectly nimble and manoeuvrable in and about town. Its high torque (226Nm) is instantly available to ensure responsive acceleration in built-up areas.

The conventional drag-producing exterior mirrors have been replaced by streamlined, low-energy cameras which are powered by the roof-mounted solar panels.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.

Renault Kangoo ZE ConceptThe polyurethane gel bumpers deform easily to soak up minor knocks, while prodiving good pedestrian safety levels.

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.

This air, which is still the most effective insulant known today, serves to moderate temperature extremes between the exterior and the interior of the car.

Thermal insulation is further optimized thanks to special treatment 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.

Interior Design

Renault Kangoo ZE ConceptEnergy consumption is minimized thanks to several energy optimization solutions.

The entire layout of the heating and climate control systems has been developed to achieve a particularly efficient trade-off between performance and energy consumption.

For example, the impression of heat is especially felt by the face and hands. Accordingly, if the cabin temperature is, say, 15 C, warmth is channelled as close as possible to these more sensitive zones (in the form of a heated steeringwheel, for example) in order to ensure that the driver feels comfortable, while using less electrical energy.

The Kangoo Z.E. Concept enables the driver to communicate with the vehicle with a view to profiting fully from its technology. For example, logos light up to signal that the vehicle recognizes occupants as they approach.

Innovative navigation system features Man Machine Interfaces (MMI) designed to provide information concerning the location of the nearest car park or charge station as a function of how much range remains.

Information is communicated to the driver via a cell phone which slots into the dashboard. Using this cell-phone for the navigation function avoids having to run an energy-consuming in-car computer.

The dashboard is divided into distinct functional units: a minimalist display providing specific data on the electric motor, while a remote control positioned between the seats incorporates a touchpad to facilitate the
keying in of data.

To facilitate loading, the hatch-type rear door and wide, folding sill ensures that parcels and other types of loads are easy to slide into the boot.
