"We recognize the situation but we are not giving up," said Schumacher, who is still employed by Ferrari as an adviser.
"Ferrari never did that in the past. You should never write off Ferrari," Schumacher said in an interview with the German news agency DPA published yesterday. "That's the good thing about Formula One, there is no time for frustration, you always look ahead head."
But Schumacher conceded that there may not be much Ferrari can do to improve the performance of its current car, since the use of the wind tunnel and computer simulations has been limited by new cost-cutting regulations.
"Before, we would do double, triple shifts, but this year it's not possible," he said. At some point, Schumacher said, the team will have to decide whether to continue trying to improve the car or start early on next season's model.
Schumacher said the most successful teams so far, Brawn GP and Red Bull, had started work on the present car very early.
