Renault DeZir Concept

Renault revealed yesterday the DeZir Concept a.k.a. the first piece of art from its new chief designer Laurent van den Acker. The new concept previews Renault's new design philosophy will make its official debut in September, at the Paris Motor Show.

Under the hood, the new concept carries an electric motor mounted in a mid-rear position in order 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. The electric motor is the same used for Renault's production electric cars but uprated to 110kW (150 hp) and 226 Nm of torque.

Regarding the charging times, Renault says that the car can be fully charged using a conventional household plug in eight hours or in 20 minutes (only 80% of the battery is charged) using a 400V three-phase current. Also, you can easily exchange the battery thanks to Renault's Quick Drop technology.

Regarding the performances, the French manufacturer announced that the new DeZir concept can hit 100 km/h (62 mph) in just 5 seconds while 50 km/h (31 mph) are achieved in 2 seconds. DeZir's energy efficiency package also includes the recovery of deceleration energy system, which is based on the same principle as the KERS (Kinetic Energy Recovery System) seen in Formula 1. This means that when the car decelerates, the kinetic energy is recovered and stored in the battery and the driver can use this energy for a temporary power boost at the moment he chooses.

Driving pleasure is further enhanced by the design of the driver interface. The dashboard visually mirrors the sensations felt at the wheel by means of a graphic display of data received from the accelerometer and speed sensors.
