Renault revealed today 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 2010 Paris Motor Show.
The new DeZir Concept exemplifies Renault’s new design philosophy and marks the implementation of the strategy derived on the notion of 'life cycle'. The 'Z' in the concept’s name is a direct reference to the carmaker’s Z.E. signature. In fact, a number of its design features are suggestive of two qualities already associated with electric mobility -- advanced technology and light weight.
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 electric motor is the same used for Renault's production electric cars but uprated to 110 kW (150 hp) of max motive power and 226 Nm of instant torque. This electric motor gets its juice from a vertically mounted 24kWh lithium-ion battery, which is located behind the bench seat and provides the car with a pure electric range of around 160 km.
Regarding the charging times, the French carmaker says that the DeZir Concept can be fully charged using a conventional household plug in around eight hours, or in 20 minutes up to only 80 percent of the battery’s energy capacity using a 400V three-phase current. In addition, 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) from nil in just 5 seconds as well as from zero to 50 km/h (31 mph) in 2 seconds. This is helped by the fact that the DeZir Concept boasts of carefully honed aerodynamics made possible by full underbody fairing and a rear diffuser. These elements allow the concept to have a low coefficient of drag value of just 0.25 Cd.
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.
