The University of Manchester enters this competition with a simple yet effective design strategy to follow on from lessons learned in 2010. The small team of volunteers from aerospace, mechanical and electrical engineering backgrounds give up their extra curricular time to take part in the project as it is not integrated into the course at the University of Manchester. A well packaged design along with mathematically backed strategic weight reduction has resulted in the lightest and smallest car to date. The team has considered cost on a larger scale than ever before, cutting down on composite manufacture and switching instead to lightweight aluminium folding. A laser cut tubular space frame provides the base for a modified Yamaha R6 engine incorporating high compression pistons, slipper clutch and intake designed using the Ricardo Wave engine simulation software. In the drivetrain, a Torsen University Special sits in a custom designed, lightweight aluminium 7075 housing. The differential is mounted in 7075 laser cut plates which are then mounted to both the chassis and the engine for increased torsional rigidity.
