Electric vehicle Asia
EVA is the first electric vehicle specifically designed as a taxi for tropical megacities. It results from a successful collaboration between Singapore’s Nangyang Technological University (NTU) and the Technische Universität München (TUM), supported from Singapore’s National Research Foundation. EVA was built from the ground up, going from concept to prototype in just two years.
The ideal concept for Singapore
By replacing fuel-burning vehicles with electric-powered ones, carbon emissions as well as local noise and hydrocarbon emissions can be reduced. The impact that taxis can make is far greater than private passenger cars due to their leveraging effect. In Singapore, taxis make up less than 3% of the vehicle population. Despite their small numbers, they account for 15% of the total distance covered by all vehicles in Singapore. Many taxis run on a two-shift rotation for up to 24 hours every day, covering an average of 520 km each.
In addition, transportation companies around the world typically repurpose passenger cars as taxis. However, the challenge of current electric vehicles is the extremely limited range and long recharge times (up to 8 hours), making them unsuitable as taxis. The heat and humidity in tropical megacities also pose unique challenges, including passenger cooling and battery pack heat management, which are specific for this part of the world. We have tackled these challenges by finding solutions for a more sustainable future in mobility.

The above-mentioned specifications describe the concept car from the year 2014 and might now be out of date due to improved components.
Developing the electric taxi in Singapore was a feat in itself, given the country’s small automobile industry.
To transport the showcased scientific ideas in the best way we had to develop and present a concept car that has the visuals of a fully functional prototype. Combined with the start from scratch and the demanding technology the finalization of the prototype was very challenging but also satisfying. For more info, see the documentation.
Tokyo Motor Show 2013
TUM CREATE has unveiled its electric taxi prototype, codenamed EVA, at the 43. Tokyo Motor Show. The vehicle and the exhibition stand serve as a perfect platform to showcase the results of all researchers from all departments in a visual appealing way to a large audience consisting of experts and private persons.
The design of the exhibition stand is accordingly very neutral and highlights the vehicle and the research results. It also corresponds to my earlier exhibitions in emphasizing the sustainable approach of the projects through the design language.
Experts as well as international media outlets were enthusiastic about EVA. The project convinced the Jury of the Bavarian State Prize for Electromobility and was awarded the eCarTec Award 2014 in the category "Product Concept / Vision".
Just as the research that I did for my diploma thesis "Gemini - Future Mobility for Singapore" established important foundations for EVA, EVA created essential foundations for follow-up projects. The design language for vehicles made by TUM, which was already developed in the earlier project MUTE, was further established by EVA. This design language has served as an archetype for later projects.
The success of EVA was an important step in continuing the international collaboration with the project TUM Create Phase 2 - Towards the Ultimate Public Transport System.
As a result of the large impact on EVA, with my contribution to the research proposal, I could secure a larger percentage of the overall budget of TUM Create Phase 2 for our department than originally intended. Hence, our department DAM - Design for Autonomous Mobility is now able to conduct fundamental design research which is essential for the success of TUM Create Phase 2.
