Info
We understand ourselves as a comparatively small group of students who constantly strives to achieve the best results possible, within our resources. Most importantly, we are going through these endeavors for all the experiences, memories and for the team spirit, both in- and externally. With the RUB26e, we aim to continue on our current streak - to improove reliability and performance every time. And yes, the "e" suffix is back! But what does it stand for ? There is only one way to find out!
Engineering Design Priorities:
Segment design
Adjustable Pedalbox
TSAC Servicability
Aerodynamics
Cooling system
Maintenance Holes

With a new evolution of a race car from RUB Motorsport, we are back – stronger than ever. Every failure became a lesson. Every setback a new motivation. No matter how often we stumbled, we always got back up. We solved problems, improved systems that we swore were already perfect, refined our workflow, and grew together as a team. We stand here today with a car we’re proud of – not because everything went smoothly, but because it didn’t, and we made it work anyway.

New chapter page 2. 2023 sees us venture out on track with an electric car for the second time. The RUB23e is an evolution of its predecessor rethought from ground up. A reduction in weight along with improved manufacturing quality stand as important achievements this year. Founded on groundwork that is a tight-knight team we believe to have a competitive package. All-white and with a selection of iconic symbols from our home region the 23e resembles a visual homage to our geographical heritage.
Engineering Design Priorities:

The beginning of a new dawn! With the 2022 season we venture into a new chapter for RUB Motorsport as we build our first electrically powered car. Since the RUB22e is designed from the ground up it no longer represents an evolution of its predecessor but a completely new car. While low weight has been in our car’s DNA for the past years, focus has shifted primarily to reliability for 2022. We aim to have our all-new charger running and want to thank our sponsors and partners for their support.
