School: INSA de Toulouse - Université Paul Sabatier Toulouse III (France)

Team: Toulouse Ingénierie Multidisciplinaire (TIM)

Car Name: TIM05 (Alternative Gasoline Prototype category)

What is special about your car? TIM05 holds the world record in the Ethanol Prototype Category: 3,350km/l set during the Rockingham SEM in 2010 and runs mainly on 100% Ethanol making it extremely environmentally friendly, as ethanol produces lesser carbon dioxide than gasoline. Its whole body frame is made using a composite sandwich structure to make it strong and very light; TIM05, including its engine and other accessories needed for the competition only, weighs 26.5 kg. Polystyrene foam, draped with silk fibre, which are recyclable and reinforced with epoxy, are mainly used in its production and its chassis, reinforced with carbon fibre.

Why is fuel efficiency important to your team? Fuel efficiency is based on three key points: a good aerodynamic, an efficient engine and a light but resistant structure. TIM05's unique shape reduces its drag coefficient to 0.12. By using the polystyrene foam-silk fibre composite sandwich structure, we are able to make TIM05 30% lighter and by improving its engine's performance, fuel needed to cover a given distance is minimised. Lower fuel consumption means lesser pollution and lesser fuel means we are able to save on fossil energy. Beyond our good performance, we hope that the technologies and innovation used in TIM05 would one day be adapted into the automobile industry.

Who or what inspired you on the way to Eco-marathon? We challenge ourselves to be better each year. Shell Eco-marathon, to us, is more than a race. It is a source of innovation and transcendence. This global event is also a unique experience for each and every one of us. Besides being able to witness our hard work becomes a reality, it is also a great opportunity to meet other teams that share our spirit.
