We are Green Voltage Racing from Clausthal UT and proud to present this year’s vehicle - the GVRacer 7! In comparison to our previous vehicle we dramatically cut down our weight by intensifying work with finite element software, enhancing the cars electronic reliability and error handling system and designing a new 5-link suspension system. We were able to reduce the moment of inertia of the sprocket by 80 % and still increase its output torque to over 940 Nm in contrast to its predecessor.

We are a young team but motivated and strongly connected to our sponsors and the Clausthal Institute Of Technology. We are aiming on a weight reduction of close to 30% compared to our last car, involving an improved design and construction. This acknowledges our ongoing progress. All our work is focused on a successful season 2014 in Hockenheim and Italy and we wish every team a thriving event. And on that bombshell, it's time to end!

Car #23
Info
In 2011 the Technical University of Clausthal will send their first team to the international competition at the Hockenheimring. Students from different study paths build up a new team, the Green Voltage Racing e.V. It is divided into different working groups to split up works and allow our members to concentrate on their favorite occupation fields. Our main target is to produce a reliable and affordable race-car which is able to compete with cars from all over the world. With its two permanent excitated watercooled synchronous machines and anti-squat/anti-dive chassis our car permits higher performances on course. Special features like our recent patterned heat control system to monitor the heat level within the accumulator stacks complete our portfolio. We thank all our partners and supporters for great 2 years of development and wish all teams a good time at Hockenheim. Follow our latest progress on www.greenvoltageracing.de.
