Red Bull RB8

Indeed their needs to be stricter rules when it comes to these parts and they should be under race conditions to pass fit, not in a lab with primitive methods. If McLaren and RBR can get away with it, the odds look high that other teams still haven't been discovered with their illegal parts yet.

Red Bull forced to change wheel hub design.

The FIA's war on innovation continues. I don't how Red Bull's are illegal but stuff like this isn't ruled to have an aerodynamic effect:

Looks like a new concept for the rear brakes:

Any idea what they're doing with the rear brakes Silver?

I don't really know mate! Maybe their own McLaren design of controlling tyre temps at the rear? I just dont remember seeing that version in the past weekends...

Not much different to ones that were deemed illegal last time except the smaller holes at the end where the wheel nut is placed are now gone?

Despite only being denied a third victory of the season in Valencia by unreliability, Red Bull is still struggling with development of its RB8.

Normally, it is the team that sets the design direction for the rest of the grid, but this year its exhaust solution has left it trailing. Not since 2009 and the double diffuser upgrade has Red Bull had to make such major updates to the car mid-season.

For Valencia, the team had another version of its exhaust\sidepod solution. This was a return to the bridge\tunnel concept first seen on the Melbourne-specification car.

Not only did the RB8 have new sidepods for the European Grand Prix, but also revised suspension, brake ducts and other aero parts.

Red Bull's decision to test its Melbourne exhaust solution in pre-season testing backfired when the system didn't deliver the results expected. Since then, it has tested several iterations of sidepod\exhaust, even returning to the launch specification for Vettel in China.

It is this tunnel solution in the sidepod that seems to promise the results Adrian Newey's design team are looking for, but it has its problems.

New rules brought in for 2012 banned the lowline exhausts used last year to create more downforce by blowing directly into the diffuser. Teams have sought to regain this blowing effect and the most popular design appears to be McLaren's, where the exhaust exits from the side of a short sidepod through a deep duct. The exhaust plume follows the downward line of the duct and the airflow over the sidepod further presses the plume back down towards the diffuser. Having the exhaust blow along the flank of the diffuser helps to seal it which creates more downforce.

Conversely, Red Bull has its exhaust exit on the top of the sidepod and the bodywork behind the tailpipe forming a ramp, which the exhaust plume follows down towards the diffuser.

In comparison to McLaren's solution, which points the exhaust plume openly at the diffusers edge, the Red Bull ramp guides it directly to the diffuser. This design should be more accurate and suffer less loss in the exhaust plume's energy.

But this longer sidepod design prevents the airflow passing low around the sidepods from reaching the diffuser. To allow the exhaust plume and sidepod flow to crossover, Red Bull devised the tunnel set up to allow the sidepod flow to pass under the ramped bodywork. In the early versions, this 50mm high tunnel did not allow the flow to pass through it as expected. Flow appeared to be reversing back out of the tunnel at speed, and its intended benefit of blowing the centre of the diffuser was not realised. So from Bahrain, the tunnel was closed off.

The suspicion is that the tunnel was too low and its inlet had sharp edges, which combined to deter airflow from smoothly passing into it.

For Valencia, the tunnel has returned and again it's limited by the rules to a 50mm height. But its entry has a significant radius to allow more flow into the duct. This flow is then routed inside the bodywork to exit through outlets flanking the gearbox. This allows the flows to cross over and enable the exhaust to be more accurately directed at the diffuser.

Sebastian Vettel and the RB8 upgrade were the class of the field in Valencia Â© LAT
Further aiding the downswept flow over the sidepod are two new fins, similar to those on the McLaren, on top of the sidepod fronts. These direct airflow over the exhaust outlet to help it point downwards at the diffuser.

At the back of the car, the rear suspension has been redesigned. The upper wishbone is shorter, bringing its mounting point well inboard from the rear wheel. This change will increase the tyre's camber change as the suspension moves, which is a method of increasing the temperature of the rear Pirellis. Accompanying the new rear upright is a new fin over the top of the brake duct area and a new shaped brake drum inside the wheel. Changes have been made to the lower wishbone as well, which is shaped to fair-in the driveshaft to reduce the drag the rotating driveshaft creates.

With this solution potentially offering more downforce and less tyre wear, the prospects look good for Red Bull. As it not only improves one-lap pace in qualifying but also in the race with better tyre management.

erm is that a diffuser above the diffuser?

Eat Sleep Watch F1 Repeat · Jun 26, 2012

Double diffuser?

BrightLampShade · Jun 26, 2012

Who ever took that picture is now in Neweys little black book

TheModestMatt · Jun 26, 2012

Its a double floor, very much like the one used (tested) on the Torro Rosso last year as they didnt have a EBD (like this year regulations). Red Bull certainlly know how to steal a mark on everyone.

I like to play a game each year, it's called "guess how many questionably-legal parts newey can put on a car before getting caught"

FIA set to force Red Bull to change engine mapping

Red Bull Racing is set to be forced to make changes to the engine mapping of its cars for this weekend's Hungarian Grand Prix, AUTOSPORT has learned, with the FIA poised to issue a clarification in the next 48 hours on the matter.

Following the controversy at Hockenheim on Sunday, when Red Bull Racing was referred to the stewards to explain why its cars were operating with engine maps that had reduced torque in the mid rpm range, motor racing's governing body is now close to acting.

AUTOSPORT understands that the FIA is planning to issue an official clarification on the matter before action gets underway in Budapest on Friday.

This document is almost certain to make it clear that what Red Bull Racing was doing in Germany will no longer be deemed acceptable.

Sources suggest that the FIA will lay down specific limits on the variations of torque that can be used throughout the rev range - with Red Bull Racing believed to have been using much less than the maximum available torque in the middle rev range.

It is understood that the new limit could allow as little tolerance in torque as two per cent, which is believed to be well inside the variation shown on the engine map used by Red Bull Racing at the German GP.

By having a greater variation in its engine mapping, Red Bull Racing was able to both minimise wheelspin and also pump more gases through its engines, therefore helping the aerodynamic benefits that the outfit still gets through the use of exhaust flow at the rear of the car.....

Red Bull looking like they will be loosing their Semi traction control / Blown exhaust trickery before Hungary. How much of an effect on the car this will have we'll have to wait and see. It could result in lost time and faster tyre wear but it all depends on how much of an effect it was really having in the first place.
