Leopard Racing is a third year competitor in the Formula SAE series. The
objective for this years team was to complete a vehicle that is well suited for
the competition performance wise while still being very reliable. The main goals
for this new design were to significantly reduce weight and chassis size from
previous vehicles, along with doing an extensive suspension analysis using tire
data. The suspension is setup in a simple planar arrangement and push rod
actuated at all four wheels, going into Penske shocks and Hypercoil springs set
up by Anze Engineering. This year we decided to stay with a similar design for the
drive system, using a Torsen differential in a custom aluminum housing. The major
change came with the decision to run Taylor-Race half shafts in order to reduce
weight. Another significant reduction in weight came from our new Keizer Racing
Wheels. The steering rack is now placed on the floor which significantly improved
driver comfort, while also helping to further minimize bumpsteer. The combination
of weight reduction, extensive suspension analysis, driver training, and more
attention to reliability should result in a strong finish for Leopard Racing in 2010.

The UVic Formula SAE Race Team has been competing in the Formula SAE series
since 2002. With a smaller team of 12 dedicated students from the Engineering
faculty at the University of Victoria, 2009/2010 has seen many improvements in
the design, fabrication, manufacturing, and assembly of the car. This year’s car,
UV10, has been developed around the use of a 4130 chromoly steel space frame
with an aluminum rear subframe housing the drive train. With a decreased wheel
base to 1524mm (60”), and design modifications to the frame and suspension,
UV10 has been designed to be quick around the continuously tightening tracks
seen at Formula SAE competitions.
With major improvements in driveability, overall stiffness, and reliability, we are
expecting an exciting year for Formula UVic Racing.
