Porsche on Thursday lifted the lid on a special new 911 model. Limited to 1,250 examples worldwide, the 911 Sport Classic is basically a 911 Turbo stripped of its fancy all-wheel drive system and PDK transmission. This means that you get a slightly detuned 3.7l twin-turbo flat-six engine sending 405kW and 600Nm of torque to the rear wheels via a seven-speed manual gearbox equipped with an auto-blip function for smooth downshifts.
