Interesting post in BBC comments.
It'll be interesting to see who brings out new designs and if they can close down RBR.
BBC Sport's Andrew Benson in Montreal: "One of the big questions this season has been just why the Red Bull is so fast. It has emerged that the single biggest reason is the design of the car's rear end, with the exhausts exiting low down in the 'coke-bottle' shape in front of the rear tyres. This smoothes the airflow around the back of the car and creates a huge amount of extra downforce, explaining the car's gob-smacking speed in fast corners. I asked a veteran engineer from another team how much lap time this was worth, guessing at about half a second. He said: 'Even more.' I was flabbergasted. He told me that four or five of the other teams are working on their own versions of the design and they would appear in the next few races. One of them is known to be Ferrari, who will have it for the next race of the season in Valencia. They need it, having dropped off the pace in the last couple of races - but if the new design is worth what my source says it is, they could leapfrog right back to the front."
