This design is nothing less than a rocket with four wheels, ready to accelerate. BMW has come up with a hydrogen powered design which is racer based on the basis of reuse. This concept car was presented in 2008 LA Auto Show Design Challenge Competition. Ordinary materials like barbeque lids and old oil barrels are used as the components of Hydrogen Salt Flat Racer. BMW has tried its best to bring forward an environment friendly racer car. The wheels are gel-nylon for obligatory flex that allows tires to be airless and re-treaded. Overall, it is a nice design for all those who believe in using a unique concept car.
