The F1 dictionary: O

One hundred and seven per cent rule, The

The cut-off restriction that denies a car eliminated from the first segment of qualifying without setting a time within 107% of the fastest Qualy One time access to a race. However, the rule is by no means absolute, and any car which fails to set a qualifying time within the 107% cut-off may be given special dispensation to race by the stewards.

O'Connell, Finbarr

Adminstrator appointed to Caterham after they were declared insolvent in 2014 but who then, quite wonderfully, assumed the role of team principal - headset, branded shirt, up on the pitwall, the whole nine yards - when they made one-off return at Abu Dhabi GP. Briefly figure of curiosity, with cult hero potential, but never heard from again after sad demise of team.

Opposite lock

The performance characteristic which occurs when a car loses grip at the rear to such an extent that a driver is required to steer in the opposite direction to that of the corner he is approaching or attempting to navigate.

Osella

Largely forgotten Italian team which competed in F1 between 1980 and 1990. The number of drivers the team got through during that decade more than outweighed the points scored - a measly five.

Osterreichring

The only circuit in F1's 62-year history to begin with the letter O, the Osterreichring had something of a fearsome reputation when it staged grands prix between 1970 and 1987 and was ultimately taken off the calendar for safety reasons. A shortened version of the track, equipped with new motorway-esque name of the A1 Ring, returned to the calendar in the late 1990s, before disappearing again. The track is now known as the Red Bull Ring.

Oversteer

The performance characteristic favoured by some drivers that features a lack of grip from a car's rear wheels when it is steered through a corner. In layman's terms: it's what happens when a car is driven too fast.

Oversteering

The performance phenomenon which occurs when the rear tyres lose grip before the fronts, causing a car to turn at a angle greater than that of the corner being tackled.

Overtaking

The process in which one car passes another during a race. Barely applicable at Monaco.
