Jul.24 (GMM) Sauber has set its sights on chasing down Mercedes.
Team boss Peter Sauber, however, admitted the task will be no mean feat.
With half of the 2012 season now gone, the Hinwil based team is sixth in the constructors' standings, a healthy haul at Hockenheim bringing Sauber within 25 points of Mercedes.
"It doesn't matter who is ahead of us, we need to always focus on attacking this opponent," Sauber told the Swiss newspaper Blick.
But he acknowledged: "We are realistic and know that Mercedes is a big adversary for a small private team."
Blick said Mercedes' driver duo of Michael Schumacher and Nico Rosberg are paid a combined EUR 30 million approximately, compared to the no more than 2 million apiece earned by Kamui Kobayashi and Sergio Perez.
Last year, Sauber finished the world championship in seventh place, three places and almost 100 points behind Mercedes.
