The first four-wheel electric Formula student car to compete

It is busy days for the Chalmers Formula Student team. This year's electric car has now stepped up to four-wheel drive and everything has to ​run perfectly for the two major international competitions this summer.

“All time between competitions and now will be spent for testing and preparing the car for competitions,” says Chalmers student Adam Olsson.

Formula Student is one of the world's largest engineering competitions for students and aims to construct, build and test a small formula car for one year, and then compete against hundreds of other university teams from around the world.

This year with four-wheel drive

It is a unique competition because it has free fuel rules, which has resulted in cars with internal combustion engines competing alongside electric cars and hybrids. The Chalmers car has been competing in the electric category since 2015 and this year the team has expanded to four-wheel drive.

“This means that we have had to integrate engines and planetary gearboxes in the front wheels. We have also made progress in our torque vectoring, where we are able to control all four engines individually. It also gives us the opportunity to use regenerative braking, where we are able to use the power from braking to recharge the battery,” says Chalmers student Adam Olsson, also responsible for low voltage and sponsor relations.

“On the mechanical side, we have developed a new wheel suspension to separate different movements of the car in order to easily change the driving characteristics according to the driver's preferences.”

International competitions this summer

The Chalmers car will be driven by three guys and one girl who all have previous experience of driving on the track – some of them even as Chalmers Formula Student drivers. At the moment, the team, which consists of 33 students from six different countries, is focusing on getting the car in top condition for this summer's competitions.

“We start with a practice competition on 28–30 June in Lund against some Nordic teams. Then we have two proper competitions planned. The first one is in the Netherlands between July 8 and 11. Then we compete in Austria between July 28 and August 1,” says Adam Olsson.

“Our goal as a team is to get to a top five position in both competitions that we participate in!”
