Create. Evolve. Thrive.
This was the mantra of our season. Coming from a very successful previous year, we set out to bring the new urban concept vehicle muc023 to the limits of current technology. We aimed to reach for greatness in the way we always have; through engineering creativity, operational ingenuity and commitment to our vision.

A diverse team formed with specializations in electrical engineering, management, mechanical engineering, and computer science. Together, we’ve not only built a car that goes to the limit of efficiency, but also one that boasts advanced self-driving capabilities. After countless hours in the workshop, we headed out to our competition in France to put our car to the test against many student teams from across the world.
There, we once more were able to achieve great success and cemented our status as one of the most competitive teams of the Shell Eco-marathon.

Coming back to our home town in Munich we felt some relief after the completion of this project, but also incoming nostalgia remembering the great times we had during the season. The vehicle of 2023 is the pride of over 80 interdisciplinary students, who poured their heart into the car. 
Welcome to the future of driving. This is muc023.
