(VIDEO) VUE, the electric Smart by the University of Sherbrooke

20/12/2012
This is not the first time that the University of Sherbrooke (UdeS) is featured on our website as they already work on an hybrid version of the BRP Can-Am Spyder and are particularly interested by electric propulsion...

For their final project study, a team of 27 students decided to develop the ultimate urban vehicle with an innovative electric powertrain.

The Smart was a natural choice because its structure is very light, then they fitted a technology that combines two independently controlled motors that are connected by a gearbox (replacing a differential), it works with belts and a pulley system to offer a natural torque vectoring technology.

Thanks to this approach the students have been able to optimize the energy efficiency by reducing losses and manage to reach a 95 to 98% efficiency.

Each electric motor develops 50kW (67hp) of power and they can offer a combined torque of 600Nm to the wheels! With total weight of 790kg only, 0 to 60kph is announced in 4.5 seconds...

After the first tests, a range of 45km has been observed in urban use from a 8.6kWh LiFePO4 battery (17.6kWh for the Smart ED).

The ultimate goal of the team - to participate in the exhibition Mécagéniale with a running prototype- has been completed!
