Aventor made a great impression at the Geneva International Motor Show. The Swiss company SOFTCAR SA presented a race car with the goal to demonstrate technological automotive innovation and that racing can have a low ecological footprint.

The vehicles can be fully recycled. The normally used carbon architecture has been replaced by an advanced composite structure and a bio-polymer bodywork. All the parts are easily removable and made with one single material. At the end of their life, the parts are removed and crushed or melted. The waste becomes a raw material, used to produce similar parts in a sustainable loop. The company also claims that it’s the first time in automotive history that the tyres will get recycled after the races.

This bio-polymer architecture is close to the mammal biological architecture, with the frame structure and the bodywork replacing the skeleton and the muscles. More generally, this architecture corresponds to a “circular economy” (CE) which describes an economical industry wherein the material flow continues to circulate in high quality after the first use. Sport cars, designed this way, become a communication vector of the circular economy for the young generation.

The idea for an ultra light and towards 100% recyclable race car was created in 2011 and the team designed a proof of concept two years later. The decision to develop, produce and market the innovative vehicle was made early 2014.

Specifications
The Aventor are ultra light. They use advanced techniques to lighten the structure and the suspension system. The Aventor with three wheels has a mass weight of 280 kg and the 4 wheel version weighs 350 kg.

The Aventor is made for urban racing. The centre of gravity is precisely settled, taking the driver into account. The guiding centre and the centre of gravity are very close, bringing a safety and a vivacity feeling to the driver.

The single seat vehicles are ready for delivery with 30 kW. The 60 and 120 kW will be available from August 2015. The torque on the rear wheel is from 406 Nm for the 30 kW to 1400 Nm for the 120 kW.

The tests made by Alexandre Mantovani and Rolf Biland at Lignières proved that theses electrical rockets have a lively behaviour and an outstanding accuracy for the positioning on the track.

Safety
The foamed bio-polymer architecture absorbs the impact energy. The frame structure has two roll bars and a double safety cage in aluminium around the driver. These parts have been designed and sized according to the 2013 FIA F3 technical regulation document. Two side wings have been integrated to the bodywork to absorb impacts on the sides, prevent the cars overlap, and protect the driver at the moment of the crash.

Energy efficiency
The Aventor is made to recover energy while braking (the three wheel Aventor only uses energy recovery on the rear wheel). On the starting line, all the cars have the same amount of energy. They are designed to run in race condition during 20 minutes + 1 lap. During this final lap, the driver which managed the energy the best way, has more power than its competitors. The efficiency optimisation on the motor controller, on the electronic, on the drive train and on the motor has been pushed to the extreme.

What’s next?
The first races are being organised in China and in Switzerland already this year.
