Swiss E-racing car breaks world record

The members of the Academic Motorsports Club Zurich (AMZ) are absolutely thrilled. For the better part of a year, students from ETH Zurich and the Lucerne University of Applied Sciences and Arts spent every spare minute working on their electric vehicle, named mythen, overcoming setbacks, and going back to the drawing board time and time again for certain components. Now, Guinness World Records confirmed mythen broke the previous world acceleration record for electric vehicles. On the military airfield in Duebendorf, Switzerland, directly opposite the students’ workshop, their racing car accelerated from zero to 100km/h (zero to 62.15mph) in just 0.956 seconds, accomplishing this feat over merely 12.3 meters. At the wheel was Kate Maggetti. This beats the previous world record of 1.461 seconds, set in September 2022 by a team from the University of Stuttgart.

“Working on the project in addition to my studies was very intense. But even so, it was a lot of fun working with other students to continually produce new solutions and put into practice what we learned in class,” says Yann Bernard, head of motor at AMZ. “And, of course, it’s a unique experience to be involved in a world record.”

Lighter, stronger, more traction
All mythen’s components, from the printed circuit boards (PCBs) to the chassis and the battery, were developed by the students and optimized for their function.

Thanks to the use of lightweight carbon and aluminum honeycomb, the race car weighs around 140 kilos (309 pounds). Four-wheel hub motors the students developed and a special powertrain give the vehicle impressive power of 240 kilowatts, or around 326hp.

“But power isn’t the only thing that matters when it comes to setting an acceleration record – effectively transferring that power to the ground is also key,” says Dario Messerli, head of aerodynamics at AMZ.

Conventional Formula One cars solve this through aerodynamics: a rear or front wing pushes the car to the ground. However, this effect only comes into play when the car has reached a certain speed. To ensure strong traction right from the start, the AMZ team has developed a kind of vacuum cleaner that holds the vehicle down to the ground by suction.

Hotly contested world record
The AMZ team had set the world acceleration record for electric cars twice before – in 2014 and again in 2016. In the following years, their record was broken by a team from the University of Stuttgart. Now the world record is back in Swiss hands, and the ETH Zurich students are confident they will not relinquish it again any time soon.
