Construction Manager reports that Dyson, the company best known for its domestic appliances, is to build a track and testing facility as part of plans to start selling electric cars from 2021.
The business, led by inventor James Dyson, has already spent £84m renovating two hangars at a 517-acre disused airfield in Hullavington, Wiltshire.
The next phase of the airfield’s development is expected to bring Dyson’s investment in it to £200m.
The 10-mile test track will be part of a "world class vehicle testing campus", according to Jim Rowan, chief executive of Dyson.
He added: "We are now firmly focused on the next stage of our automotive project strengthening our credentials as a global research and development organisation."
It is not yet clear where Dyson intends to manufacture the electric cars.
