Room for improvement, says BMW tech boss
Williams-BMW needs to raise its game for the remainder of the season, says BMW technical director Mario Theissen

Theissen says he is not unhappy with the team's performance this year - but he has insisted there is plenty of room for improvement.
The British team is third in the world championship, behind Ferrari and McLaren. But its poor finishing record of four out of 16 starts has affected its points tally.
However, Ralf Schumacher took Williams-BMW's first Grand Prix win since 1997 with victory in the San Marino GP in Imola. He also outclassed his brother, Michael two weeks ago to take the chequered flag for a second time in Canada.
"Reliability has been a very big problem for us and I don't think we have enough points," said Theissen ahead of this weekend's European Grand Prix, which marks the start of the second half of the season.
"It is not good enough to have finished just four races out of 16 starts. That is a very bad record and we must make improvements."
He added: "On the other hand, we are very pleased to have been able to win two races this season."
