Dyson has unveiled plans for its new electric vehicle (EV) test facility.
The vacuum and appliance company says it is building a 10-mile track, as well as research and development buildings, at a disused airfield in Wiltshire as part of its plans to start selling low carbon cars from 2021.
It has already renovated two hangars at a cost of £84 million, with the next phase of development to take overall investment at the site to around £200 million.
About 300 staff are already based at the facility, which has three further test buildings due to open in coming months.
The firm promises its EVs will feature driverless technology and has suggested they may not look like conventional vehicles.
Jim Rowan, CEO of Dyson, described it as a “world-class vehicle testing campus” and said: “We are now firmly focused on the next stage of our automotive project, strengthening our credentials as a global research and development organisation.”
