24. Lotus Carlton
This crazy and menacing sedan is virtually unknown in USA despite the fact it was produced by GM`s subsidiary Opel in Germany and Vauxhall in the UK, and it once claimed the title of the world`s fastest four-door. Powered by the 3.6-liter six delivered 377 hp which was massive for the standards of the day and the performance was thrilling as well. The 0 to 60 mph run was over in just 5.2 seconds and top speed was record breaking 177 mph.
