Red Bull Racing RB15 speculation thread

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

Anyway back to the RB15 and I think it will be able to achieve race victories just as the rb14 did especially in Max's hands. The Honda is now clearly the equal of the Renault and in some respects was further beyond Renault by the end of the year. If Red Bull could win with bits and pieces of a Renault engine then imagine what it can do with factory honda engines while still having STR as a test bench.

Is there any hope that we can get back to the subject matter which is the RB15? Rehashing old debates about Honda in years from 2013 to date is not relevant. Note that some off topic comments have been removed

Adrian Newey has decided to adopt the solution that reduces the temperature of the rear tires and that had unleashed controversy last year when Mercedes had adopted this idea.

The Red Bull RB15 is being born with the rear rims with holes: this is the news that is coming from Milton Keynes. They follow the path that was done last year, which included the controversy for Mercedes.

It will be interesting to understand if the solution that is implemented on the RB15 will only serve to control the temperature of the rear tyres or if, instead, it will also have an aerodynamic effect.

The FIA technical commissioners had immediately said that the holes were legal, as they had a marginal aerodynamic effect, and had been designed by Aldo Costa as a solution to avoid overheating of the rear tyres of the W09, and the judgment was then confirmed also from the FIA/stewards during the Mexican GP who had been summoned by Mercedes, fearing a claim from Ferrari that on the matter had submitted a request for regulatory clarification.

The team of Brackley, fearing a protest of Ferrari, for some GP had preferred to run with the closed holes, but once conquered the 2018 title, the silver arrows had not hesitated for a moment to exploit a very expensive change.

Rumors from Maranello claim that the 670 will not have this wheel rim solution, at least not at the start of the 2019 season

Funny how Italian media always credit the technical director for inventions pursuit by a team.

The new rules on the front wing would disadvantage the beaten trim and consequently also in Milton Keynes would be adapted

As already emerged for Mercedes and more generally depending on the trends expected for 2019, the wider wing profiles at the front should lead the single-seaters to assume a lower inclination of the leading edge of the diffuser. A factor that seems to have also conformed to Red Bull according to the latest rumors reported on the pages of the newspaper La Gazzetta dello Sport by technical expert Paolo Filisetti. In fact, thanks to the extreme inclination of the nose downwards and a shorter wheelbase than the direct competition, about 20 centimeters if compared to the Mercedes of 2018, the RB14 was able to provide first-class chassis performance.

However, the new requirements dictated by the wings called to divert more centrally the turbulence seems to have imposed on the teams a review of the layout of the vehicle. At Milton Keynes, however, they would not have abandoned the key concept that has raged in the last decade, but would have resorted to a less extreme solution. A sort of 'compromise' that would be in line with what Ferrari did last season. Reduced inclination, halfway between that of the RB14 and the more 'neutral' Mercedes which has a minimum diffuser attack angle (1.2 degrees). Such a decision would also affect the wheelbase of the car, with an increase of about 8 centimeters. In spite of this, the compactness of the Honda engine should allow the RB15 to maintain a rather small section of the sides compared to the Toro Rosso STR13 of last season. The first Red Bull car to be equipped with the Japanese power unit.

Equally interesting seems to be the shape of the nose, defined as "evolution of the current one, especially with regard to the power supply of the socket S-duct. The deflectors in front of the sides have been elaborated, combined with the bottom equipped with longitudinal 'rails'. Perhaps, precisely because they are among the most sought-after solutions, they will not be visible at the presentation". Obviously, the greatest uncertainty is linked to the performance of the already mentioned Honda power unit that from the noise captured should maintain the architecture implemented in the second half of last season. The updates would focus on the combustion chambers, the turbocharger and the ERS system. All to increase performance, but also reliability.
Biggest changes coming to the RB15.

Very interesting indeed, but wouldn’t you need to be a team member to know such details?

Nah. Pure speculation. All based on the AMUS article from last week.

Btw. same stuff came up when they banned EBD. This is what Adrian told media in the past:
"I used rake as no exhaust blowing was available and I will try to do it again"
I'm pretty sure this has not changed much, especially when you look at how good last years car performed.

I seriously doubt that the rb15 will have less rake. I expect it to have as much rake as the Rb14. This is what separates a red bull from a Mercedes (aside from the engine and the silver) . Expect the rb15 to utilise more of the air going over the sidepods in a coanda effect on to the rear diffuser as used on the rb14.

Totally right. Those article is bullshit. Concerning the rims with holes I believe RedBull is stating to use it in 2019, so that try to convince other teams and FIA to banner it because of excessive costs and so block mercedes evolution on tire management.

Fully agree regarding the wheel rim holes. Clever way to cook it up in media so FIA keeps an eye on it and maybe completely bans it right at the beginning. We all know know that tyre overheating was and likely still is the achilles heel of Mercedes.
