Sauber to debut blown diffuser

Sauber will become the latest team to run a blown diffuser exhaust when they debut their device next weekend in Germany. In recent weeks, many teams have adopted the diffuser style, however, it has not been easy for any of them.

"We will have several aero updates on our C29, including a modified diffuser. It's a package which is again a step in the same direction we've been pursuing for Valencia and Silverstone," said tech director James Key.

Key is also hoping that the team can continue their good run of form, having finished the last two races in the points, although he admits Hockenheim is a very different track to Valencia and Silverstone.

"After two good races we obviously want to carry on the momentum as best we can at Hockenheim. It's quite a different track to the last two.

"It's more a mix of slow speed corners in the final section, where you can gain lap time if you get it right, and to a certain extent quite a bit of straight line running. It's gonna be a tradeoff between downforce and drag. Braking stability will be important to get the best out of the slow speed corners.

"There are some high speed areas, which we think will suit our car well. Most interestingly it's a circuit where you have one or two good overtaking opportunities.

"Tire compounds are extreme, they are either very soft or very hard, so it will be interesting to see how that works out for qualifying and the race. This will increase the workload on Friday and Saturday to make sure we have a good understanding of both compounds."
