eLi16

OUR VEHICLE FROM 2016

So far eLi16 has participated at the EducEco Challenge in Colomiers, France, the Shell Eco-marathon Challenger Event in Le Mans, France and the regular Shell Eco-marathon Europe, which took place in London this year. At the Shell Eco-marathon, an additional challenge was the ascending track, eLi16 proofed here it’s reliability and efficiency once again.

Due to differences within regulations, eLi16 competed with two different variations – one vehicle with silicon solar panels for the EducEco, one without for the Shell Eco-marathon.

Also, one major innovation was the implementation of our driving automatism, which automatically adapts the vehicle’s speed and acceleration according to an optimized driving strategy.
