Despite earlier estimates of his 2010 salary at EUR7m, Germany's Bild newspaper said Michael Schumacher's actual EUR25m income this year makes him the highest earner in pitlane. Sebastian Vettel, who recently moved into a new farm in Switzerland, comes in with 12m, with Fernando Alonso earning 18m with Ferrari this year. Vettel's teammate Mark Webber makes 7m, much less than Lewis Hamilton at 16m. Reigning world champion Jenson Button earns 3.5m less than his McLaren teammate, and Nico Rosberg's deficit to Schumacher is a staggering 19 million, the newspaper said. Nearer the bottom of the list, Adrian Sutil is on 1.7m, and fellow German Nico Hulkenberg is making 1m in his rookie season. The figures include personal sponsorships.
