In 2009, the aim for the Fortis Saxonia Project is to be at the starting line for the Eco-Marathon at the EuroSpeedway in Lausitz with an improved version of the Sax 3 which to date, is the most efficient TU Chemnitz vehicle. A task that a team of around 20 students from various departments was happy to take on. The result is the Sax 3.1, a three-wheel vehicle weighing a mere 45 kg, which Team Saxonia hopes will build on last year’s impressive performance when it comes to this year’s Shell Eco-Marathon on May 7 to 9, 2009. The up-and-coming vehicle builders have put a correspondingly large amount of energy, know-how and high-tech into further improving their experimental vehicle, the Sax 3, to increase its range of 2,500 km by several hundred kilometers. So to further optimize the Sax 3, they logically had to have efficient measurement technology in the test and optimization phases.
