The Boxster roadster carries through into 2010 unchanged after some significant updates last year. Power comes from a 255-hp 2.9-litre flat-six cylinder, while the S model gets a 310-hp 3.4-litre version. Both come with six-speed manuals as standard, but Porsche’s optional seven-speed dual-clutch PDK gearbox is optional. When it comes to handling the Boxster is the very definition of agility, poise and balance. The cabin design is plain, but focuses the passengers on making rapid progress. As with any Porsche, the options list is Pandora’s box: only open if you dare.
