I'm sure Ferrari's glad that they're not supplying RBR anymore

The German magazine, however, says that Coulthard and Australian Webber, 30, are reporting a general lack of aerodynamic grip, in stark contrast with the data findings of the newly-commissioned wind tunnel in Bedford (UK).
Seems that they cannot generate enough heat on the bridgestone tyres. Th e MP4/20 had a similar problem at the start of the 2005 season and reworked their suspension i think. Seems like red bull are having the same problem.m3_lover wrote:David Coulthard has refused to make a damning appraisal of Red Bull's new car for 2007 despite failing to shine at the wheel so far.
Also in the hands of the Scot's new teammate Mark Webber, the Adrian Newey-penned machine had an unreliable and slow start to its on-track life, prompting recollections of Coulthard's recent assertion that heads should roll if the RB3 bombs.
When asked about the car, Coulthard is quoted as saying by Auto Motor und Sport: "I do not want to avoid the question, but you would not judge the effectiveness of a new plane if you had only flown it in the simulator and for a few metres down the runway."

Auto Motor und Sport adds that the car was up to four kilometres per hour slower at Valencia than engine supplier Renault's works team last week, and that the new high speed gearbox was not even used due to faults.
The RB3 is reportedly also failing to effectively use Bridgestone's control tyre.
"Even after long runs the rubber looks like new," the magazine wrote
Previous studies involving wind tunnel testing and computational experiments have indicated the huge potential of a rotating cylinder placed on the leading edge of a aerofoil as a high-lift device. The rotating surface (cylinder) energizes the airflow on the upper surface of the aerofoil, which has the potential to delay the separation of the boundary layer and thus the onset of stall as well as producing a larger pressure gradient enhancing the lift of the aircraft. As a result of these effects, the stall angle and maximum lift coefficient have been shown to significantly increase during wind tunnel testing.
Didn't Mclaren have a similar problem at the start of the 2005 season and they sorted it out by revising their suspension geometry?ginsu wrote:If they aren't getting enough heat then they aren't pushing the car hard enough because they don't have enough grip. If they don't have enough grip it's usually because of a lack of downforce, but suspension geometry can affect grip usually in the lower speed sections of the track.
