Red Bull RB9 Renault

[Juzh]

I dont think its so much RB having better in high speed corners, but overall a better car if we had tyres that lasted 300 laps.

No --- – who wouldn't have a better car if the tyres magically lasted longer.

It's obvious red bull and mercedes chew their tyres much quicker than ferrari or lotus. It's also obvious that merc and red bull are the fastest cars in terms of pure pace (3-4 in poles) but can't maintain it for as long as ferrari and lotus. Hence it is a logical conclusion if tyres wouldn't degrade as fast, they'd be fastest troughout the race as well.

Perhaps Vettel + Malaysia + Bahrain + Canada = hole in theory? Monaco was very strong too if it wasn't for the silver bus.

The point is not if their car is overall faster, but better in quick corners. From the - in my opinion flawed - notion that RB have 'way more' downforce than anyone else, you might expect they would be whilst in qualifying trim.

My point is that that they didn't seem to be better in the quick sections of Barcelona even in practice/qualifying.

I think the reason for this difference between RB5/6/7 and 8/9 is quite logically put down to exhaust configuration. Before rule change they could blow diffuser without damaging aero efficiency; now they''ve made a clear choice to go with something bulkier as the low speed performance gain outweighs their loss of aero efficiency..

What about the fact that if Ferrari and Lotus heated their tires up faster, they'd then qualify faster, which would put them alongside RBR & Merc.

40 degrees wasn't enough for ferrari to heat them up in bahrain or barcelona? I cant recall atm.

That's what they claimed, but obviously I don't really know if its the whole truth.

So what's with the new exhaust? Ceramic?

So what's with the new exhaust? Ceramic?

Ceramic coating.

Thermal barrier ceramic-coatings are becoming more common in automotive applications. They are specifically designed to reduce heat loss from engine exhaust system components including exhaust manifolds, turbocharger casings, exhaust headers, downpipes and tailpipes. This process is also known as "exhaust heat management". When used under-bonnet, these have the positive effect of reducing engine bay temperatures, therefore lessening the intake temperature.

Although most ceramic-coatings are applied to metallic parts directly related to the engine exhaust system, some new technology has been introduced that allows thermal barrier coatings to applied via plasma spray onto composite materials. This is now commonplace to find on high-performance automobiles and in various race series such as in Formula 1. As well as providing thermal protection, these coatings are also used to prevent physical degradation of the composite due to frictional processes. This is possible because the ceramic material bonds with the composite (instead of merely sticking on the surface with paint), therefore forming a tough coating that doesn't chip or flake easily.

Although thermal barrier coatings have been applied to the inside of exhaust systems, this has encountered problems due to the inability to prepare the internal surface prior to coating.

Zircotec?

Zircotec?

Most likely yes ...

[The_Truth]

I think the Zircotec solutions was used by Mercedes back in the 2011 season with the EBD, the WO2 was melting the rear-end of the car.
