As far as supermodels go, the second-gen Maserati GranTurismo is a knockout. Super-easy on the eye, the all-new 2+2 coupe takes a giant step forward in technology, adopting an aluminium-rich body, a modified Alfa Romeo Giorgio architecture and a twin-turbo V6 from the acclaimed MC20 supercar. The result sees the Italian beauty chase rivals as diverse as the Porsche 911 and Bentley Continental GT.
