Renault Twizy Z.E. Concept

The Renault Twizy Z.E. Concept is an all-electric compact vehicle which features a width of just 1.1 meters, faired wheels and two seats located one behind the other. It previews the brand’s future electric models that will be intrododuced from 2011.


Renault Twizy ConceptPresented by Renault at the 2009 Frankfurt Motor Show, the Twizy Z.E. Concept is a compact electric vehicle designed as a solution for mobility in urban environments.

The wraparound bodywork creates a reassuring cocoon and the futuristic cabin can accomodate the driver and one passenger, positioned one behind the other.

The agility is maximized by the low weight (420kg), low centre of gravity and the ultra compact dimensions (2.30m in length, and just 1.13m wide), which result in a turning circle of just three metres and a footprint barely larger than that of a scooter.

Twizy Z.E. Concept is powered by a 15kW (20hp) electric motor that develops 70Nm of torque and allows for performances comparable to a 125cc scooter, with a top speed of 75 km/h.

Exterior

Renault Twizy ConceptThe exterior is characterized by four-wheel arrangement, and open bodywork with a futuristic, pearlescent white tone. The wheel fairings are not spherical but octagonal, and cover the tyres entirely.

Along with the pearlescent white and blue hub caps, they form a pleasing, harmonious design in which the wheels can no longer be seen rotating.

Instead, the only visible movement is that of the hub caps, so Twizy Z.E. Concept appears "to glide silently along the road."

The front and rear ends of Twizy Z.E. Concept are equipped with a luminous matrix display, the honeycomb-shaped diodes of which allow the driver to interrelate with his or her immediate surroundings.

Interior

Inside, the cabin is brightly lit thanks to the bodywork’s extensive glazed surface.

The blue and white colour scheme creates a soothing atmosphere which isolates the passengers from the stress of urban activity.

Optimizing the vehicle’s range is simple and worry-free, with a poetic touch: remaining range is depicted by a lotus flower on the dashboard, with petals that close progressively as the range decreases.

Renault Twizy Concept InteriorFor the cabin, the priority has been to make Twizy Z.E. Concept easy to drive.

Displays are located at eye level at the base of the windscreen, and grouped in honeycomb-shape clusters which are easy to differentiate.

For the passenger, getting into the rear seat is simple: the seatback is attached to the roof of the vehicle, allowing the lower part of the seat to pivot.

The rear seat can even be adjusted to suit the passenger’s height: the seat cushion can be turned over to become a booster cushion and afford a child better visibility.

Renault Twizy ConceptWhen the cushion is used as a booster in this way, it frees up a load volume of 10 litres, as a complement to the initial 50 litres, and in complement to the 3 litres provided by the cubbies on either side of the steering wheel.

Technical features

A deformable structure protects occupants in the event of a frontal impact while lateral reinforcement bars provide protection in the case of an impact from the side.

The retention systems include a four-point harness for the front seat and a three-point seatbelt at the rear, plus a driver airbag and two lateral airbags.

The open chassis calls for neither heating nor climate control, both of which consume a significant amount of energy.

Renault Twizy ConceptThis, coupled with the vehicle’s low weight (it tips the scales at just 420kg, complete with batteries), contributes directly to Twizy Z.E. Concept’s range which can reach 100km.

The lithium-ion batteries for Twizy Z.E. Concept are located beneath the two seats. They are charged by means of an extendible cable located behind the Renault logo at the front.

This cable can be plugged into a 220V 10A or 16A domestic socket, and will fully charge the batteries in just three and a half hours.

Twizy Z.E. Concept is the forerunner of one of the all-electric mobility solutions that Renault will introduce from 2011.
