Energy-efficient Racing on one litre of fuel

Windesheim’s Blue Racing Team has designed the innovative Blue Bolt and is competing with this sustainable car in the Shell Eco-marathon in London.

The race in London is divided over several categories and takes place from 22 to 28 May. Windesheim’s Blue Racing Team is competing in the 'Urban Concept' class and complies with the specifications required by Shell for this class. In 39 minutes, the cars have to drive ten laps on a circuit near the London Aquatics Centre at a set speed of about 30 kilometres per hour. Then a jury assesses the participants’ energy consumption efficiency, expressed in number of kilometres per litre of fuel.\

The team that designed the highly economical Blue Bolt is made up of twenty-one students from various Windesheim programmes. The Industrial Design Engineering (IPO) programme did the design, the Mechanical Engineering and Electrical & Electronic Engineering programmes produced the car last year and students of the Communication programme announced and promoted the car on their own website in text, images and film. This year a new team has perfected the car, under the supervision of lecturers. This team consists of students from the Mechanical Engineering, Electrical & Electronic Engineering and Industrial Engineering & Management programmes.
Sustainable design is gradually becoming a tradition at Windesheim. Since 2007, student teams have built a number of technically innovative and sustainable vehicles, from a solar boat to a race car. The first time Windesheim took part in the Shell Eco-marathon was in 2015.

The Design

The Blue Bolt is the result of the assignment to design the most economical car possible. The design focuses specifically on weight and streamlining. The car’s chassis and hood are made of carbon, it has a wooden dashboard and most of the other material is aluminium. Mechanically speaking, the development of the steering system was the biggest challenge. Also, current limitation was a bottleneck that needed to be cleared. Student Sebastiaan Hoes is satisfied with the result. "It's fun working on an innovative product in a multidisciplinary team. You learn how to deal with other priorities, experiences and interests, just as you will need to collaborate with other disciplines in your later working life. We are proud of our design and collaboration."

The Race

The goal of the Windesheim team is to finish in sixth place or better in the Shell Eco Marathon in London. That’s quite ambitious given there are about 200 teams taking part from colleges and universities across Europe, including Delft University of Technology and the University of Twente.
