James Dyson, famed for his vacuum cleaners, hinted Thursday that his electric car would be more energy efficient than rivals - and with "very large wheels" for city and rough-terrain driving. Releasing brief details of patents filed 18 months ago ahead of the car's expected launch in 2021, Dyson said in a memo shared with media: "the patents show a car with very large wheels, giving a low rolling resistance and high ground clearance. "This makes a vehicle suited to city life and rough terrain but could also contribute to increased range and efficiency," he said, cautioning however that current designs were far from set in stone.
The British engineering entrepreneur acknowledged the patents were deliberately light on specifics but said "they do reveal some of the ways we might improve Battery Electric Vehicles".
