PORSCHE 911 GT3 RS
Check that wing! The giant aero addition on the back of the latest Porsche test car can only belong to the extreme GT3 RS model. Carparazzi says the wing is unlikely to make production but it promises up to 50 per cent extra rear downforce and could be part of a track pack. Other keys to the RS package are wider tracks and a 0-100km/h sprint in about 3.5 seconds.
