J-turn

A J-turn is a driving maneuver in which a reversing vehicle is spun 180 degrees and continues, facing forward, without changing direction of travel.

[1] A J-turn differs from a bootleg turn in that the vehicle begins in reverse gear.

[2] The narrowest J-turn was performed in a Renault Twingo, between barriers set 3.78 metres (12.4 ft) apart.

The diagonal length of the car, 3.70 metres (12.1 ft), 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.
