About Lightyear



Subscribe to our newsletter



Lightyear is developing long-range solar electric vehicles. The architecture of the vehicle is based on Lightyear’s design philosophy.

With a laser focus on efficiency, Lightyear is developing the powertrain, thermal management system, and solar roof with integrated electronics. In order to deliver a convenient user experience, Lightyear is also developing the software architecture and user interface of the vehicle. These developments are protected by patents.

The development of different components based on Lightyear’s architecture is being outsourced to specialised partners, as well as production, assembly and most of the testing activities. The only exception is the production of the solar roof which is done in-house.
