LONDON: Volta Trucks has started real-world testing of the first Volta Zero prototype using production specification components.
The electric vehicle was developed in industry-leading time of eight months from first designs to running vehicle. It will start series production in December 2022.
The start of trials at automotive testing centre Horiba Mira in Nuneaton, UK, follows soon after the reveal of the first prototype chassis of the Volta Zero – the world’s first purpose-built full-electric 16-tonne commercial vehicle designed specifically for inner city logistics.
Affectionately named "Volta Minus One" by development engineers, as the forerunner to the production-specification Volta Zero, the prototype vehicle uses the proposed production specification chassis frame and drivetrain of the finished vehicle and will test all the electro-mechanical and thermal properties of the truck.
This includes the high-voltage battery supplied by Proterra, and the compact rear axle, electric motor and transmission eAxle unit from Meritor.
The unconventional bodywork of the prototype is designed to protect the development driver from the elements when the vehicle is moving at speed. The production vehicle will feature a cargo box design, but the prototype uses a flatbed to allow engineers to add different levels and locations of loads to test its weightcarrying capacity.
The prototype Volta Zero will continue testing at Horiba Mira over the coming months. The forthcoming test and development programme with this and later-specification prototypes also includes periods of cold weather testing north of the Arctic Circle, and hot weather testing in southern Europe.
The programme will ensure that the production-specification Volta Zero vehicles deliver the durability and reliability expected by fleet operators and vehicle owners.
These learnings will be taken into the production of Pilot Fleet vehicles that will be tested and evaluated by key customers who have signed up for both testing and the option to purchase series production trucks. This is designed to develop their understanding of how the Volta Zero will integrate into their operations.
