Power is seductive. Any driver who has experienced the thrill of a high-performance car’s straight-line acceleration will have instantly been won over.

In addition, the Aussie-bred saloon has already tasted test victory.

Last but by no means least is Porsche’s Cayman S, voted the champion in our recent Greatest Drives 2007 test. We headed to North Yorkshire to assess the fast foursome...
