In the 1950’s Shell staff organised a competition amongst themselves to see how far they could go on a set amount of fuel. The event grew and they opened it up to schools, universities and private individuals. By year 2000, when I heard about it, there were 126 teams competing worldwide, the World Championships were held on F1 racetracks, eg, Magny Cour in France and Silverstone in England. It is still going on. The only reason I stopped was I posted to Africa.
