Feature: Ecurie Aix RWTH Aachen
At Evodays HQ we are lucky to have 3 university Formula Student/FSAE teams within a 60km range. To make things interesting, our 3 local teams also represent 3 different countries: Belgium, The Netherlands and Germany.
This is great for us as it means we are able to closely follow the progress of each of these teams throughout the calendar year, including design, build, and the finished car as they head off to compete in the various Formula Student/FSAE competitions around the world.
As it’s December and the German Christmas markets are out, I decided to catch up with Ecurie Aix, from RWTH Aachen to learn more about their stunning car “05 Berna,” which was built for the 2016 competitive year.
The team was founded by a group of RWTH Aachen students in 1999 and named Ecurie Aix to honour the motorsport history of the region. Being close to Spa-Francorchamps, they took their inspiration from the Formula 1 team Ecurie Francorchamps (Eurie meaning “Racing” in French) and Aix-la Chappelle (the French name for Aachen).
Ecurie Aix built their first electric car in 2010, then again in 2014. They do have a nice archive of previous cars in their workshop, although they explain that some are missing as they are on loan to sponsors. The design concept of their vehicles flows nicely from year to year, with deliberate, careful evolution. These are beautifully engineered cars and extremely aesthetically pleasing.
