Description
The Lightyear One is a large hatchback, with the bonnet, roof and boot clad with 5 m2 (54 sq ft) of solar panels, with a WLTP (Worldwide Harmonised Light Vehicles Test Procedure) range of 725 km (450 miles) and designed with a drag coefficient of Cd=0.20. The company Lightyear claims there are 1,000 solar panels across the car that can add 50–65 km (30–40 miles) of range per day during summer.[3][4]
The car is all-wheel drive, with four in-wheel electric hub motors powered by a low-mounted battery.[2] It seats five adults and luggage.[4]
History
The solar panel design was born out of the Solar Team Eindhoven's solar-powered cars for the World Solar Challenge. Design work on the One was carried out together with GranStudio in Italy.[5]
