AN ELECTRIC BEAUTY
Renault DeZir is powered by an electric motor mounted in a mid-rear position to optimize weight distribution over the front and rear wheels. The vertically-mounted 24kW/h lithium-ion battery is located behind the benchseat and provides the car with a range of 160km. Battery cooling is ensured not only by the air channelled from the front to the back of the car, but also - and above all - by the flow of air that enters through the lateral scoops concealed behind the aluminium panels on either side of the body. The basic motor is the same as the unit used for Renault's production electric cars, although an evolution has enabled its power and torque to be uprated to 110kW (150ch) and 226Nm respectively.
Three battery-charging methods can be employed:
* a standard charge using a conventional household plug (fully charges the battery in eight hours).
* a fast charge using a 400V three-phase current (charges the battery to 80 per cent of its capacity in 20 minutes).
* a fast battery exchange thanks to Renault's Quick Drop technology.
