TORONTO, ON – On April 28, 2011 at 6 p.m., the University of Toronto Formula SAE Racing team is revealing to the public their greatly anticipated 2011 competition vehicle, “UT11,” at the Mechanical Engineering Building.
Over the past nine months, a diverse group of talented U of T Engineering students have been devoting their time to the realization of this project. UT Racing is one of 500 collegiate design teams to compete in the internationally recognized Formula SAE series, which tasks students to develop, manufacture and race an open-wheel, open-cockpit type combustion vehicle each year. With a 14-year team history, including three world championship titles (2003, 2005, 2006), this unveiling mark the beginning of what is to be another formidable and rewarding competition season.
The design of UT11 was targeted at improving in the areas of manufacturability and drivability. Vehicles in the Formula SAE series must be student-driven, therefore driver-skill development is essential to achieving high-vehicle performance.
By making design choices that enabled UT11 to be manufactured with little complexity, the team was able to get the car on-track with adequate time to accommodate driver training and vehicle testing. The most influential design choice in this regard was the decision to use a steel-tube chassis over the carbon-fibre monocoque design, as seen with UT10.
Another challenge in the series is the limitation on maximum engine size a team may use, this restriction largely motivated for safety reasons. UT11 focused on development in auxiliary engine systems, such as the intake and exhaust to increase power. UT11’s stainless steel-stepped exhaust header provides a power increase and broader torque curve. By widening the rpm range of +80 per cent power output, the stepped header design provides a more forgiving power band suitable for amateur drivers.
A winning vehicle begins with these two components. At Formula SAE competitions, teams competitively present their design innovations, cost analyses, marketing plans and on-track performance which is then evaluated by a jury of experts coming from the motorsports, automotive and supplier industries.
There are nine competitions worldwide, of which UT Racing attends two: Formula SAE East (FSAEM), held in May at the Michigan International Speedway, and Formula Student Germany, (FSG) held in August at the HockenheimRing. UT Racing is one of only two Canadian teams to ever compete at FSG. Each year the team competes, the racing team continues to represent the high-calibre education available at the University of Toronto.
