Dyson is planning to build a 10-mile test track in Wiltshire where the privately-owned company – famous for its cyclone technology vacuum cleaners – will put new electric cars through their paces, according to news reports.
The BBC News website said the track and other facilities are part of a plan by the firm – founded by inventor James Dyson - to start selling a "radical" electric car from 2021.
The company bought the disused airfield at Hullavington, near Malmesbury in the UK county, two years ago and has already renovated two hangars built at the site - originally a World War II RAF training station.
That redevelopment has cost £84mln and the next phase of the airfield's development would take Dyson's total investment to £200mln, the BBC report said.
The BBC report said Jim Rowan, chief executive of Dyson, commented: "We are now firmly focused on the next stage of our automotive project strengthening our credentials as a global research and development organisation," he said.
The company has yet to reveal any details about its electric car and no prototype has been built.
