Theres a completely different record for cars with driven wheels.
This is an engineering challenge that is involving schools, universities etc. Its also a great adventure. Noone has EVER done this before and I think it'll be not only the largest ever numerical increase in the land speed record, but the largest percentage increase as well.
Anyway, designed in Britain, engineered as far as possible in Britain, Jaguar fuel pump, Eurofighter jet engine...hoe much more British do you want?
