Dyson is to grow its electric vehicle programme workforce by 300 people in a bid to ramp up the pace of development before its first car reaches the market in 2020.
The new workers will join the existing 400-strong team working on the project.
Dyson has already doubled the number of scientists working on its battery programmes over the past year.
The company has said the programme, which up until now has been based in its Malmesbury headquarters in the Cotswolds, will shortly move to its new research and development base in Hullavington in Wiltshire.
Company founder, Sir James Dyson said its first car will carry a premium price tag but will not be a sports car.
The firm hopes to use its low volume first model development and production period to establish supplier relationships.
It plans to produce two mass produced EV models following the launch of its debutant.
