Yes, blown diffuser was Renault I think?
Still NOT. Blow diffuser was the name of the game back in 2009, when Brown GP, William, and Toyota found a loop hole in the regulation. It deemed illegal by 2010 (If I recall correctly).
Wasn't that the double diffuser? I thought Renault mastered the exhaust blowing?
In 2009, Honda engineers brought a double diffuser on the Brawn GP car. In 2010, Red Bull made a blown diffuser along with a fake painted exhaust system. Further, the position of the exhaust pipe was moved so as not to extract hot gas flows to seal the diffuser. But Adrian Newey found a loophole in 2011 as well. At that time, it was still considered a blown diffuser. At the same time, during tests at McLaren, their system was copied, after the original version was unsuccessful. In 2012, there were still changes in the technical regulations, which would completely prohibit the use of a blown diffuser, at the same time certain restrictions were imposed on the mapping of the motor (remember cold and hot exhaust?). Then in 2012, McLaren brought an exhaust system based on the Coanda effect. Further paint does not see the point.
