The first drafts of Dyson’s closely guarded electric car designs have emerged, showing a vehicle with unusual proportions that could be used off-road.
The patent filings are the first clue to what the “radically different” car pledged by British inventor Sir James Dyson might look like.
Dyson said the patents were “deliberately light on specifics” but revealed some of the ways in which the firm was trying to improve on current electric vehicles in its £2.5bn development project.
The car’s very large and narrow wheels could allow increased range and efficiency, according to Dyson, essential for battery-powered vehicles. The wheels would be kept as close to the front and the back of the vehicle as possible to make the car “highly manoeuvrable … and improving handling on rough terrain”.
Despite the high ground clearance, the vehicle’s overall height would be lower than most SUVs and a larger, thinner battery pack than rivals would help give more space inside. The driver would be seated lower in the cabin, with a shallow-angled windscreen improving the aerodynamics of the car. The patents were filed 18 months ago but only published this week.
The cars are now expected to launch in 2021, a year behind the original date.
Sir James, the billionaire inventor whose fortune was built on revolutionising the traditional vacuum cleaner design, has so far indicated that it would be a premium vehicle, implying a price tag in the range of a Tesla, which costs £38,000 for a Model 3 or around £70,000 for a Model S. The designs underscore that the new car will also need bespoke parts such as tyres.
Dyson has said that the vehicle will go on sale in a limited number of countries at first, with China likely to be a frontrunner, and would be “entirely designed by Dyson, manufactured by Dyson, and sold by Dyson”. The car would build on Dyson technology used in its other products, such as its own motor and battery types.
The 72-year-old inventor, who was an outspoken supporter of Brexit, provoked anger by announcing last year that the car would be manufactured in Singapore rather than in Britain. The company is about to start construction work on its new plant in Singapore, because Dyson believes there is a bigger market for electric vehicles in Asia.
However, Dyson maintains that the car is a British project, with the design, engineering and testing of prototypes being carried out in its Wiltshire base, the ex-military Hullavington airfield where hangars have been converted to house the project.
In an email sent to more than 500 staff working on the vehicle, Dyson stressed the need to keep the details of his new product secret. However, he said patents were needed as the car would “include fundamentally new technologies and make some inventive leaps”. But he also cautioned that “we do not always use patents or make products based on patents that we have filed”.
He said that competitors had missed opportunities by adapting electric vehicles from existing formats, but Dyson’s was “a vehicle which has been developed from the bottom up”.
The British government has pledged to ban fossil fuel vehicles by 2040, in response to climate change targets and air pollution concerns.
Dyson has urged the prime minister, Theresa May, to bring forward the date of the ban by a decade to 2030, describing the 2040 target as “madness”. He told the Financial Times that he believed the electric car market had been underestimated, adding: “I believe it’s driven not so much by subsidies as by genuine desire of the public to have silent and non-polluting vehicles.”
