Zoe is Renault’s solution to Zero Emission mobility for all. In addition to being a choice for everyday use and readily affordable Zoe is the first pure-electric car to be designed from the ground up as such. Zoe is packed with the latest technology and boasts no fewer than six world premieres geared to enhancing user-friendliness, range and connectivity.

Unveiled at the 2012 Geneva Motor Show, Renault Zoe will go on sale this autumn.

“We wanted Zoe’s design to embody both a sense of breakthrough technology and core automotive styling cues. The car’s eco-friendly dimension is expressed in its pure lines which appear to flow along the bodywork. Its contemporary proportions combined with sculpted volumes make Zoe a reassuring and captivating car.” Agneta Dahlgren-Hermine (Zoe Design Project Manager)

“Zoe’s interior design reflects its modern, ‘eco’ character, with a bright colour scheme evocative of purity, plus the latest interactive technology in the form of the Renault R-Link tablet. The dashboard moulding has been designed to resemble the blade of a wind turbine.” Dominique Marzolf (Interior Designer)

In terms of autonomy, Renault has developed the ‘Range OptimiZEr’, which combines three major innovations (new-generation regenerative braking, a heat pump and MICHELIN EnergyTM E-V tyres).  Due to this, the range of Zoe is the highest of the electric vehicles in mass production.  In the NEDC cycle, Zoe is homologated with a range of 130 miles. In real conditions, for example, in suburban use, the owner will generally achieve around 60 miles in cold weather and 90 miles in temperate conditions.

New-generation regenerative braking recovers practically all of the energy otherwise wasted during braking, without any significant impact on Zoe’s on-road dynamics. The car offers a smooth drive with no jarring electric motor braking. The system works in two ways: The kinetic energy produced under deceleration and braking is recovered by the motor so that it can be converted into electricity to charge the battery. This feature is also fitted to Fluence Z.E. and Kangoo Z.E. When the driver presses the brake pedal, the system intelligently distributes the braking effort between applying the brake pads and the electric motor brake with a view to maximising the use of the electric motor brake and charging of the battery.

The heat pump provides excellent thermal comfort without detracting from the vehicle’s range. This system, which operates in the same way as reverse-cycle air-conditioning, consumes very little electricity. It produces warm or cool air by simply reversing the cycle of operation. The heat pump generates approximately 2kW of cooling or 3kW of heat with just 1kW of electricity. The cabin temperature is also more constant since it is not affected by the heat given off by the motor.

Zoe is the only electric vehicle to feature the Chameleon charger. Patented by Renault, this charger is compatible with all power levels up to 43kW. Charging batteries at a charging station can take between 30 minutes and nine hours. For example, Zoe can be charged in an hour at 22kW. This intermediate power level extends battery life and puts less pressure on the power grid than the fast-charging of batteries at 43kW.
