British-based car mag Auto Express has named the Porsche 911 the greatest high-performance car of all time from a pool of 60 cars produced over the last 50 years. The mag states that the latest version produced from 2000 to 2005 is "the result of continuous, fastidious development since the first model's launch in 1963." After pondering the selection for a while we tend to agree with the mag's choice of the 911 as the top pick. No car has been developed and continually improved over a longer period of time while still maintaining the same performance identity as this Porsche, and somehow Porsche engineers continue to make it better with each new iteration. The other five finalists were the 1950-59 Lotus Seven, 1960-69 Jaguar E-Type, 1970-79 Lotus Esprit, 1980-89 Ford Sierra Cosworth and 1990-99 McLaren F1. The McLaren would also be a great choice, but it's brief production run and super-high price tag make it one of the great footnotes in the history of high-performance cars rather than an established player in the segment that has withstood the test of time. We're interested to know what your top pick would be?
