Ted Kravitz was down in the pit lane when the updated Red Bull first took to the track and here’s his reaction: “No wonder they needed to fly out a new chassis – the whole rear of the Red Bull is different. There’s a completely different exhaust positioning and that means all the rear bodywork and some bits of the rear suspension are new as well. Previously, the exhaust pipes exited fairly far back towards the rear wing and quite tight to the centreline of the car - more or less under the ‘a’ of Renault if you look at a picture of where the engine manufacturer’s logo is on the rear of the car. But now they exit much further forwards and further outboard – much like the Sauber exhausts. In this respect Sauber are well ahead of Red Bull: they brought their version of this to the third day of the first test at Jerez and have been developing it ever since
“Whoever thought of it first, it’s been beautifully executed on the RB8. The intention seems to be to channel the exhaust not so much over the top of the diffuser but actually around the outside of the rear wheels, tidying up the disturbed air that flows off the rear tyres. It’s quite a big job ahead of Red Bull because they don’t really know how the hot exhaust gas is going to affect the back of the car, so these final days will be crucial to see if there will be overheating problems - both on the rear bodywork, rear suspension and rear tyres.”
