The classic British Mini is in the running to be voted the most important and influential innovation of the past century in science and technology.
Voting is taking place on-line and Alec Issigonis' compact transverse-engined, front-wheel-drive design is the only British car on the shortlist.
It is up against some impressive opposition, including such inventions as radar, the hovercraft, ultrasound, penicillin, the jet engine and the world wide web.
The poll is taking place to coincide with National Science and Engineering Week under the patronage of world-famous astrophysicist Professor Stephen Hawking of Cambridge University.
The complete shortlist of Great British Innovations can be found on the website specially created for the poll where votes can be cast until 24 March.
