I gave up subscribing to Autosport magazine, but have usually bought a
copy of each post-race issue. In 2013 two of those have contained
previews of the upcoming race, containing lots of track trivia.
This is what it had for Bahrain:
Clockwise track, 15 corners (6 left, 9 right)
Run to turn one: 400m
%age of lap at full throttle: 66
Length of pit lane: 420m (loss of time 22s)
Safety Car: Only once (8 GPs)
Fuel: 2.7kg/lap (loss for 10kg = 0.3s/lap)
Gear changes: 52/lap
Pitlane is said to the 2nd longest, Silverstone is longer, Melbourne is
shortest.
Other sources put Melbourne at 280m/17.9s and Silverstone at 420m/21.2s.
www.vivaf1.com have lots of track data, some of it may be inaccurate -
they show the Greater Noida pitlane as 600m for example.
