2007 Circuit Data

2007 Circuit Data

Most of this data originates from the FIA, but the published source
from which I have taken it is the 18th edition of 'Formula 1 Yearbook',
published by Chronosports, edited by Luc Domenjoz.

of the fuel burnt in litres.

'Race Fuel' is simply the fuel burnt per lap multiplied by the number of
race laps, and is in kilograms. The 'Race Dist.' is the actual race
distance which is laps multiplied by lap length plus the 'Offset', which
is the distance between separate start and finish lines.

'Litres' is a calculated amount for the race distance based on an
assumed specific gravity for the fuel of 0.73.

'Km/Lt' is the approximate distance achieved by burning one litre of
fuel.

Note that the numbers are calculated with reference to the race distance,
and ignore parade lap, formation lap, slowing down lap - all of which
may burn perhaps half of the race speed fuel per lap.
