2022 - Espera Montbéliard

Saviris

Saviris is a competition racer powered by a motorcycle engine and weighing just 600 kg. Performance is breathtaking.

Saviris is a magnificent model in the green color of British racing cars (UTBM/Espera photograph).

Record time

It took just two and a half months for the thirty students from Espera Montbéliard to create this prototype, from blank sheet to first workshop run. As usual at Espera, half the team worked on the mechanics and the other half on the bodywork. In the second prototype (Oniric), the teams rotate, so as to work at all stages.

The name Saviris comes from the combination of the name of a comic strip character, Savitar, god of speed, and Artemis, the goddess of the hunt in Greek mythology.

Racing in the 50s and 60s

Saviris' inspiration comes from the British racing cars of the 50s and 60s. Like the Aston Martin DBR1, for example. But beware, the specifications impose a limited budget of €50,000. Which isn't much when you're starting from scratch. The engine, for reasons of size and cost, is that of a motorcycle. It develops around 100 horsepower. This may not sound like much, but the weight is kept to a minimum, at just 600 kg. 100 hp is enough to deliver interesting performance on the racetrack.

There's a slight spatula effect, like on Franco Sbarro's Canam (photo by Julien Maillard for UTBM/Espera).
