French designer Marc Devauze has come up with the the Bugatti TypeZero concept, a proposal for an electric-powered, single-seat Bugatti sports car..

Inspired by the 1920s' Type 35 - Bugatti's most successful racecar ever – this study of a single-seater electric hypercar features four electric motors, one in-board of each wheel, with energy stored in detachable lithium-air batteries installed on either side of the driver.

Lithium metal-air batteries can store more than 5,000 watt-hours per kilogram. (A123 M1 cells are around 120 wh/kg) That's more than forty-times as much as today's high-performance lithium-ion batteries.

The vehicle’s battery pack is located either side of the driver and can easily be removed through separate openings, which gives the drivers the possibility to easily hot-swap discharged batteries with charged ones during a race, although at 5 kWh/kg this feature seems intended only for endurance racing.
