McLaren to again test blown diffuser at Hockenheim

McLaren is still not committed to qualifying and racing with a Red Bull-style 'blown diffuser' exhaust layout.

At Silverstone, the British team tried the specification in Friday practice but reverted to the original setup for qualifying and the race.

McLaren and its drivers still head both world championships with more than half the season now run, but boss Martin Whitmarsh admits the team is "under no illusions" about Red Bull having the faster car.
