The F1 dictionary: J

Japan

F1-mad nation which has not only been a permanent fixture on the calendar since 1987 but has also furnished the sport with a number of blue-chip companies such as Honda, Toyota and Bridgestone. Unfortunately, its driver well has - for now - dried up. 

Jerez

Circuit in southern Spain which was once the host of the Spanish and European GPs but in more recent times has been a regular test venue. Shunned, however, for 2016 pre-season action.

Jones, Alan

Gritty Australian star of the 1970s and 1980s who delivered Williams their first World Championship in 1980.

Jorda, Carmen

Lotus's Spanish development driver and favourite of the world feed director.

Jordan, Eddie

Former team boss and lover of bright shirts.

Journeyman

The description that all F1 drivers dread, implying a career of dead-ends, midfield running and little razzmatazz. 

Jump start

The moment when a driver moves from his grid slot before the red lights have gone off. Before the era of advanced timing technology this could sometimes go unpunished by officials - but not anymore, with offenders swiftly given a penalty by race control. See also: Penalties.
