Fiat believes its Centoventi concept will be the key to mass-market EV adoption and will be the cheapest electric car on the market.

The small car is based on a modular configuration, where customers can add accessories and extra batteries at any time, by buying them online or through retailers.

Fiat says one of the concept car’s strong points is that customers will no longer have to wait for facelifts or special editions, as all parts can be upgraded or replaced easily.

There will be a range of 120 accessories, ranging from seats to bumpers, to allow the car to be tailored specifically to the users requirements.

The car will come with one battery pack, providing 62 miles of driving. Up to three additional packs can be bought or rented, giving a maximum 310 miles of range.

There will also be a removable battery pack under the rear seat, which drivers can take out and charge indoors, if it is not possible to park the car in a charging bay.

The dashboard and door panels have small holes into which a multitude of additional components, such as cup holders or additional storage bins can be fitted.

The multiple charging socket is located at the bottom of the windscreen. This is a cable reel housed underneath the trim, which eliminates the need for a cable cavity in the boot and, thanks to its central position, is equidistant from charging points on either side, or can act as a hub for several vehicles in case of energy sharing. The socket lights up in the dark and can be used as an electric torch and windscreen defrosting device.
