Vodafone McLaren MP4-27 Mercedes

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.

It helps drive flow through the diffuser as well.

How? Can you please explain?

I'll buy that. Just one question. Would it help attach the flow over the whole cross-section of the rear wing plate? It looks quite small a wing to affect the airflow of the whole width of the rear wing. :?

It helps by further reducing the pressure behind it; which helps the extraction of the diffuser. A bit like the gurney tab most teams stick along the diffuser edge.

I think that this will create a vortex which will help prevent flow separation. Brilliant aero design!

Whitmarsh confirmed on the SKY sports coverage that they have a new floor for this weekend. That's why they were running with all these rear aero sensors.

Btw, can anyone enlighten me on the purpose of these monkey seats?

The monkey seat provides a place for the monkey to sit other than on the drivers back. Its a good luck thing

Martin Whitmarsh said Hamilton had been running old gear box in FP1 and FP2. Decision is not made if he has penalty or not.It remains unclear.There is a crack on gearbox that's all he said but they are running still.Find it amazing.Whats your thoughts

Depends where the crack is. If it was on the casing I think it'd survive. 2 words. Monza 2009.

Rubens' gearbox caught fire (I mean a proper fire. Flames were coming out of the engine cover, not just smoke) in Spa 2009, he didn't replace it for the next race. He won.

I think it would be a risk to not change the damaged gearbox. Hamilton then may be quali for pole, but he will be racing with a damaged gearbox which could fail every lap. So IMHO it's smarter to change the gearbox and take a 5 places grid penalty, but be sure the gearbox is working fine from race start on. But i do not know how big the damage of the gearbox is..

Im not sure a crack on the casing would be so benign... don't forget, the casing is part of the car's structure. The suspension loads are fed into the gear casing, then into the engine and into the rest of the chassis. Even if it didn't fail, it would affect stiffness.

It's a wearing bearing I think.. they found particles in the oil which shows that a bearing is wearing.. They said its 99% they will change it and if they didn't for this weekend that it wouldn't last past this race anyway so it makes sense to change it here where Lewis goes well and can make up places due to the nature of the Circuit.
Don't Kanye me. Or I'll Chris Brown you and Tiger Woods your mother.

Especially as it has to last the whole of bahrain anyway. If they don't change it don't they run the risk of getting hit twice? Once if it gives up the ghost and the second time in Bahrain when they have to put in another gearbox.
