Sebastien Buemi and Michael Schumacher top the list of most prolific overtakers in 2011.
According to data produced by Mercedes, Buemi has made 112 overtaking moves and Schumacher 111 over the 18 races of the year to date.
Kamui Kobayashi has made 95, Jaime Alguersuari 90 and Sergio Perez 89.
Ignoring overtaking moves made on the first lap, Perez and Buemi have the most with 82. The next highest are Jenson Button (77), Mark Webber (76), Alguersuari (74) and Schumacher (71).
The Turkish Grand Prix saw the most overtaking moves with 85, followed by Canada (79) and China (67). The least passing was seen at Monaco (16), Australia (17) and India (18).
Mercedes also analysed the effect the Drag Reduction System has had on overtaking this year. Out of 804 “clean overtakes”, DRS accounted for 363 (45.1%). This excludes passes on the first lap, passes due to damage, and overtakes on the Virgin, HRT and Lotus cars.
The highest proportion of DRS-assisted passes was seen at the Abu Dhabi Grand Prix, where 89% of passes were achieved with DRS. The next highest were the European (81%), Indian (78%), Turkish (59%) and Spanish (57%) Grands Prix. DRS passes outnumbered ordinary passes in eight of the 18 races so far.
The least DRS passes was seen (sometimes due to wet conditions) in the Monaco (13%), Hungarian (20%), Canadian (22%), Japanese (26%) and British (27%) Grands Prix.
