Or eight if you include this.
This is the classic Citroen 2cv. Road Tax in France is levied depending on the tax horsepower rating, which is a calculation made on engine capacity, not power. The 2cv has two chevaux vapeur - that is 2 steam horses. It is the car that put France properly on the road in 1948, and it stayed in production until 1990. In total 3,872,583 of them were made.
well - I will let the shaggy bloke in the video explain it
(that makes 10 horses so far)
According to one source, "Citroen was so confident in the 2CV's abilities that it offered the prize of a brand new car to the first person who rolled one on to its roof - and well over half a century later, the prize still hasn't been claimed." If you have ever followed one down the road you may doubt this - they are the leaniest cars I have ever seen.
(The video is not the right aspect, I know - but it was loaded to you-tube by someone other than me)
