Cars, Culture and the City

CAR interviews 'Mr GT3' Andreas Preuninger

The latest Porsche 911 GT3 boasts an all-new 469bhp 3.8-litre flat-six and is quicker than the legendary GT3 RS 4.0, but fans of this hardcore icon have voiced their concern over its new dual-clutch PDK gearbox and its steering (both the electric rack inherited from the 991-generation Carrera, and the new rear-axle steering).  Ahead of the 911 GT3's unveil at the 2013 Geneva show this week, CAR had exclusive access to the car, and to the man who headed the team that engineered it: Porsche's head of GT series production Andreas Preuninger.
