After our first electric car, Furka, gained the overall first place in 2010, we plan to continue the path of success with our new race car novena. With 15 novices our renewed team is young and hungry. This ambition led to a car that is lighter, smaller and more efficient then Furka. The special features are our two self-built motors that weigh just under 10 kg each, producing a peak power of 35 kW. As the AMZ is famous for extreme lightweight construction, we tried to continue the tradition by building a car that should be able to aim at the magical 200 kg barrier. To reach this goal we tried to make every part as light as possible leading to a one piece carbon fibre monocoque, carbon fibre rims, a self built two-stage gearbox and carbon fibre driveshafts. This year our goal is to win the design event and the dynamic events by being the fastest car on the track (including the combustion cars).
