Porsche has taken the wraps off its all-new Boxster at the Geneva Motor Show. The entry point to Porsche ownership is now 35kg lighter, more efficient and has more power than ever. The styling has also been refreshed, but in true Porsche style the changes are evolutionary rather than radical. A longer wheelbase, widened track and bigger wheels (18-inch on the Boxster, 19-inch on the Boxster S) will be the biggest clues if you park the new model next to its predecessor.
