Red Bull RB7 - exhaust positioning 23 February 2011
At the very first test in Valencia Red Bull introduced a new blown exhaust layout. The long flat pipe blows into the area just in front of the rear tyres (see red arrows). In this section (highlighted in yellow) the underbody has been cut away so that the air can blow directly under the side channels of the diffuser. This solution appeared to have been copied by Force India at the most recent test at Barcelona's Circuit de Catalunya.
