2015 F1 car launches

Ah OK so in order to best use high fuel pressure they would want a higher turbo pressure alongside it?

Would that have the knock on of using more fuel though? Or will it allow the same fuel/air pressure mix to happen quicker, allowing more freedom in timing setup which can improve efficiency?

Nose of the FW37 doesn't look great.

No it doesn't look great but better than last year.

It's the other way around really, higher fuel pressure gives them the ability to run more boost but they don't need to, obviously running more boost will use more fuel and they're still fuel limited so there wont be huge benefits.

Higher fuel pressure should allow the injection event to occur within a smaller timeframe potentially allowing higher rpm, ISTR that none of the teams were anywhere near the rpm limit last season although that appeared to be by choice rather than due to an inability to reach it.

Apparently Sauber are ditching their grey colour scheme this year and will have a blue and yellow livery.

Lucozade?

Colours of Banco Brasil, makes sense with Felipe Nasr in the team.

I like that - it would stand out in an increasingly dull, grey grid.

Skeeter · 26 Jan 2015 at 10:06

I agree. A nice combo. His GP2 car looked a bit fussy, but the core colours are decent.

can we get the original post updated with individual launch dates? have they all been anounced?

lotus just released a rendering of their 2015 car

Will be interesting if McLaren move back to white/red, I doubt they'll want any silver on their car post Mercedes.

As has been pointed out numerous times, the colour had nothing to do with Mercedes. They were white and red in 1995 and 1996 with Mercedes engines, only moving to the black/white/grey scheme when West came onboard in 1997. That they stayed with the same basic theme (though chrome rather than silver) after West left may be a nod to Mercedes, but nothing more. McLaren were just a customer team after their works deal finished, so if it was a Mercedes thing, that would have finished at that point too, but they kept the chrome theme going.

It has all but been confirmed that they will change colour scheme next year, but more because will be seen as a change of philosophy and direction. It probably will be white and red as a nod to Honda if they have no title sponsor to announce, but who knows what the long-term theme will be.

I do wonder if the average, casual observer may get confused if the Mercedes are going chrome and they may think it's the mclaren?

Confused that the Mclaren is back leading the pack instead of floundering midfield?

The reason that the cars didn't go anywhere near the RPM limit is due to the fuel flow limit peaking at 10500rpm. Once past this point there isn't any scope for increasing the power but the losses from the engine will continue to increase.

Higher pressure should allow better control of the injection and better atomisation of the fuel. This will help increase the resistance to knock and hence allow more boost.

Sauber to unveil the C34 on the 30th, this Friday.
Same day as Ferrari.
