Red Bull RB8 Renault

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

Red Bull is back to it's raked setup, why they can pull it off all of sudden is anyone's guess...

Same same.

I don´t have the energy to go back a few pages but any reason why they have gotten rid of the "strakes" below the rear wing?

Could it be for a greater stalling effect of the diffuser from the DDRS system? Pure speculation...

An interesting theory on the Red Bull DDRS: http://mccabism.blogspot.com/2012/10/re ... e-drs.html
It's somewhat surprising that the media has yet to suggest a connection between Red Bull's new double-DRS system, and their unique 'underpass' duct.

To recall, the underpass is a means of separating the 'coke-bottle' flow along the flank of the sidepod, from the exhaust-flow, sweeping down from the top of the sidepod. The coke-bottle flow feeds the starter-motor slot and the top surface of the diffuser's trailing edge, while the exhaust jet partially seals the side of the diffuser and increases the flow over the rear brake-duct assembly.

The underpass is fed by the flow along the flanks of the sidepods, which in turn is fed by the front-wing wake. By connecting the flow along the flanks of the sidepods to the low pressure area under the beam wing, the underpass not only assists with rear downforce, but also pulls the air faster over the front-wing.

Red Bull's double-DRS system apparently stalls the central section of the beam wing, and it's precisely this part of the beam wing which is pulling the air out of the underpass. Thus, if the beam wing stalls, then the underpass stalls, the flow along the flanks of the sidepods weakens, and front-wing downforce and drag are reduced.

One can speculate then, that Red Bull's double-DRS is a system which reduces front-wing drag as well as helping to stall the beam wing and diffuser.

According to F1.com the ramp was indeed shortened

That sidepod is now basically the acer duct type seen on Ferrari and McLaren, but with a ramp that's basically a CF plank to guide the exhausts.

Are there limitations in the regulations to Mcl or Ferrari making an exhause chute/cover that has a ramp extension? Does it have to conform to radius rules (i.e. the radius for the acer duct, mcl bulge, red bull bulge chute)?
