The narrowest J-turn was performed in a Renault Twingo, between barriers set 3.78 metres apart. The diagonal length of the car, 3.70 metres, meant stunt driver Terry Grant had a gap of 4 centimetres (1.6 in) on each side. This happened at the National Exhibition Centre in Birmingham, UK, at the PistonHeads show on 11–13 January 2008.
