Dyson's battery-powered vacuums are very good. So it made sense when Sir James said he was going to use the knowledge gained from building those to make an electric car. Only it didn't work out. In an interview with The Times, Dyson revealed the car and admitted he'd sunk over $600 million into the project. With a range of over 600 miles and a 0-60 time under five seconds, the SUV-like vehicle would have been strong competition for Tesla and other electric car makers, but unfortunately, each one would have needed to sell for nearly $185,000 just to break even. Dyson said he plans to keep all the employees that were working on the project, instead dispersing them throughout the company including working on batteries he hopes to sell to other automakers.
