Glossary


Safety Crews 
On asphalt rallies, priority drivers are supported by a safety crew which passes through the stages in advance of the competitors to report back on weather and surface condition, which may have changed following reconnaissance.

Scrutineers
Technical officials who check the legality of WRC cars before, during and after each event.

Sequential Gearbox
The type fitted to most WRC cars. Gear selections are made by gearshift rather than the traditional 'H' gate manual system typically found on production cars.

Service
There are usually three service periods during a WRC day – 15 minutes in the morning, 30 minutes at lunchtime and 45 minutes in the evening. Teams can perform repairs or modifications to cars during these periods, and select their tyre choice for the following loop of stages.

Set-up
The choice of tyres and suspension adjustments to give a WRC car maximum performance.

Shakedown 
The opportunity for crews to test their competition cars on terrain similar to the rally before the event starts. Competitors must drive through the shakedown stage at least four times, with all passes timed.

Stages 
The competitive sections of the rally, also called special stages, where drivers and co-drivers drive as fast as they can to complete the section in the shortest time possible.

Stage Time
The time recorded from the standing start of a stage to the flying finish.

Stop Control 
A point 200-500 metres past the flying finish where the car must stop to have its time recorded.

Studs
Metal spikes fitted to the treads of winter tyres to give grip on snow and ice.

Super-Special Stage (SSS)
A stage – often set up in a sports stadium – with two parallel tracks that enable two drivers to race each other. Super-special stages are also run in city centre locations.

Target Time 
The official time allowed for a WRC car to complete a non-competitive road section. Time penalties are applied if competitors check-in earlier or later than their target time.

Time Card 
Carried by the co-driver, the time card is a record of stage times and time control arrival times throughout the rally. The card is stamped by officials as the rally progresses and provides proof of a competitor’s whereabouts in case of a dispute.

Time Control 
The place where cars must stop to get an official passing time recorded by rally officials.

Time Penalty
Rally crews are penalised 10 seconds for every minute the car is late to a time control – for instance a stage start, service-in control, service-out control. Checking-in early to a time control carries a stiffer penalty of one minute for every minute early.

Turbocharger 
An exhaust-driven turbine that pressurises the fuel/air mixture into the engine to enable it to develop more power. All WRC cars use turbochargers (turbos) which develop 4-5 times the pressure of the turbo on a road car.

WRC 2 
WRC 2 is the leading feeder series to the FIA World Rally Championship. Competitors nominate seven point-scoring events, from which their best six results count towards their final standing. The series is open to four-wheel-drive cars from the R5, R4, S2000 and N4 classes.

WRC 3 
A support series open to two-wheel-drive cars homologated under the R1, R2 and R3 class rules. Competitors nominate up to six point-scoring events, from which their best five results count towards their final standing.

Zero Car
A course car driven through a stage before the competitors start to alert spectators that the section is live. The zero car is preceded by the triple zero and double zero cars.
