muc018

OUR VEHICLE FROM 2018

After the very successful debut of our first Urban Concept last year, we focused on the next challenge for our team. With muc018 we present for the first time in the history of the TUfast Eco Team an autonomous driving vehicle.

Our focus was mainly on developing an integrative and innovative vehicle concept. The autonomous components are completely modular and can be fully removed for the traditional competition where a normal driver is steering muc018. They do not present any additional weight. While developing and manufacturing the muc018, the autonomous system was perceived as an equally important part of the vehicle. Therefore, special attention was given to the complete but nonetheless reversible integration of all components into muc018.

Just like its predecessor muc017 our new car muc018 will compete at the Shell Eco-marathon in the Urban Concept class and features, in addition to its efficiency, also lighting, weather resistance, comfortable sitting position and a baggage compartment.
