The first half of pre-season testing has produced varying form from Merc GP's W02, which is proving to be rather inconsistent.While the car has shown moments of pace, resulting in Schumi finishing the Jerez test with the week's second fastest lap time, on most days the team has finished outside the top half of the timesheets.
Reliability has also proven to be a bit of a worry, although the bulk of the gremlins have befallen Rosberg.
And with half of pre-season testing already completed, Schumacher fears his W02 is not a Championship-winning car.
"The target is still the same as we said weeks ago: to hopefully be, with this car, on the podium and maybe, if things go very well, to win a race this year," said the 42-year-old
"That's probably the maximum we can talk about, but it is very difficult to judge our performance at the moment against the others because obviously we will improve the car a little bit further to the Bahrain race.
"But, how much compared to the others, that's the question mark."
