the project

Formule ETS is a student engineering team from École de technologie supérieure, in Montréal. The team has been designing, manufacturing and racing Formula SAE race cars for slightly more than 30 years with one common goal since then :

WIN.

The cars that come out of the ETS' workshop reflect our  design philosophy. Therefore, we are in an endless pursuit of designing the lightest car year after year.

The latest car weighs 324 pounds and features a custom 450cc engine. The APEX sits on four 10-inch Hoosier tires mounted on custom double moulded carbon fibre wheels. The decoupled suspension setup integrates the anti-roll system on the custom through-rod damper which considerably reduces the weight of the entire suspension system. The front dynamic package is located underneath the car by using pull rods in order to lower the height of the center of gravity of the vehicle. 

An innovative upright and spindle system led to a complete brake system redesign. The car is now equipped with two custom 7075-T7351 aluminium front calipers machined on a 5-axis CNC milling machine. This year we designed and machined a 4 pistons brake caliper for the rear brake which is mounted on the differential support.

The chassis has been designed around the most important piece of the car; the driver. This results in superior ergonomics and increases the driver's confidence. To further complement the ease of driving, a fully adjustable locking dovetail mechanism for the pedal box ensures a comfortable driving position for any driver no matter their size.  

A new construction method significantly increased the rigidity and durability of the aerodynamic package while still featuring a double-action DRS ("Drag Reduction System") for the rear wing.
