One stat I have researched before is drivers who qualified in a lowly
grid position, but went on to stand on the podium.
One race was won from 20th or lower - John Watson, Long Beach 1983,
22nd. Seven other races have been won from 15th or lower, fairly
recently by Barrichello (GER 2000, 18th), Räikkönen (JPN 2005, 17th),
and Alonso (SIN 2008, 15th). 17 others were won from outside the top
10 on the grid - Alonso won this year's European GP from 11th.
Five drivers have finished 2nd from 20th or lower (most recent, JPM in
GER 2005, 20th). 46 other 2nds from outside the top 10 - two this year,
RAI, BHN, 11th & PER ITA 12th.
Ten third places from 20th or lower - BAR CDN 2005, 20th, RAI BHN 2006,
22nd. One hundred and seven (107) others from outside the top 10 - 20
since 2000, two in 2012 (PER CDN, 15th & MSC EUR, 12th).
Note: These figures are based on qualifying positions rather than
starting positions, although some of the most recent may well be
starting/grid positions. Most websites/ref. books don't record actual
starting positions until recent years.
