German solar mobility provider, Sono Motors, has announced a partnership with Team Rosberg Engineering (TRE). The co-operation includes the development, simulation, and production of a suspension and chassis system for Sono Motors’ electric car Sion.

In particular, the partners are focused on the design of a safe and robust sub-frame, which provides sufficient resistance in the event of a frontal crash while at the same time meeting the installation space requirements of the solar-powered Sion.

Founded by Formula One world champion Keke Rosberg, TRE is one of the leading providers in the field of vehicle development and brings many years of experience and expertise from the field of motorsports to the development of passenger vehicles.

Jona Christians, co-founder and CEO of Sono Motors, says: “TRE is a leading player in chassis development, incorporating specialist knowledge from racing engineers into passenger-car manufacturing. Furthermore, with a German supplier, we have short delivery distances and short delivery times. Meanwhile, both companies’ visions align to drive sustainable mobility forward.”

Nico Rosberg, shareholder of TRE and son of the founder Keke Rosberg, comments: “As a sustainability entrepreneur, it is a particular concern of mine to contribute our expertise to the development of Sono Motors’ Sion and to further develop the future of alternative mobility concepts.”

TRE CEO, Eckardt Döhrer, adds, “We are pleased that we can contribute our profound know-how and TRE’s more than 20 years of experience in chassis development to the development of the Sion and thus help shape technological progress in future-oriented mobility concepts.”

The TRE chassis systems are already installed in the next generation of prototypes of Sono Motors’ Sion, which is planned to be launched at the end of the year.
