The Newton is powered by four large 278v batteries positioned on the underside of the truck that can propel the vehicle up to 50mph. Fully charged, the vehicle has a range of 130 miles. It can be re-charged on board or through domestic mains or a standard three-phase socket.

As well as being zero emission, the Newton’s body panels are built from an ultra light, state-of-the-art fully recyclable composite material manufactured by Omnia. This substantially reduces body weight and increases the payload capacity of 4,000kg.
