2008 Jerez Testing Sept

I'd imagine it's 'toroidal', which is a traction drive system. If you google it you'll probably come up with a wikipedia article I think. We did something on this at university. Basically two hemispheres in contact - an input and an output. Depending on the angle between their axes you get different drive ratios.

Nakajima's fastest lap was a 1:23.2

3.6 seconds slower than the fastest car, the BMW. Bearing in mind that they were running grooved tyres, the lap times should be very similar to last season.

"Our objective wasn't chasing a time ago because, among others things, we were very heavy with fuel, but to finish the day without errors and being able to do what was asked of me.... I can't be more pleased." - Sam Michael

No time chasing

That quote was referred to in this article, talking about tuesday. Although the same probably counts for today.

I don't know Italian, but it's a great video to show visually the transfer of energy through the tranny.

A flywheel does not exclude the use of a battery

Q: Finally, talking packaging of KERS. Because of the different aero the car will look different, but the cars could also look different because of KERS as you've got to package capacitors or batteries or whatever you choose to specify. How much has that affected the packaging of the car and therefore how much does that effect the aero of the car?

Vasselon: From a visual point of view the KERS will not be visible. So in most cases it will be very difficult to detect a car which runs KERS from one which doesn't. Yes, it's big, I think 30, 35 kilo, but not big to the point that you can say 'here's where the KERS is mounted'. We have already been discussing this in the last Technical Working Group (TWG), not all the teams, but several, are planning to put KERS below the fuel cell, so this kind of integration will make KERS almost invisible.

Q: That's if they're running a battery.

Vasselon: No, why?

Q: Well if you're running a mechanical system, then you can't put it under the fuel cell, the flywheel...'

Vasselon: You have different types of flywheels. Starting from the same energy storage concept the flywheel, you can either drive it mechanically via the gearbox and you have to be reasonably close to the 'box, of course. But you also have electrical flywheels, the flywheel is just a motor generator. In this case you can put it where you want, you just need wires.

Thank you Timstr. I must have picked up my idea regarding flywheels being generators from a similar source.

Thank you Scotracer & Whiteblue. My understanding of the flywheel KERS is much better now. Your understanding is greatly appreciated.

A glipmpse into the rear wing of 2009???

[Ogami musashi]

Yes Rear wing and diffuser.

Dude, did you bother to have "a glimpse" at the very first page of this topic before posting this?

Good spot. To my eye that was not obvious.

I'm not sure if I'm correct, but Bridgestone is planning on using reflective paint to differentiate the compounds for the night race in Singapore, maybe that's what the purple stripe is.

Nothing looks better than the shiny tread of the Bridgestone full wets with reflective paint glistening under the Singapore GP lighting scheme.

If it rains, this race is going to be a nightmare.

Does anyone know of a site that has pictures from Ferrari's testing at Mugello this week? I haven't found any as of yet.

Regarding possible rain at the Singapore GP, maybe the event will have to be cancelled if it rains too much, or the drivers will refuse to drive if the conditions are not appropriate.

mx_tifosi, here you have someones from Tuesday, with Badoer as driver

If it is humid then dew could be a problem, the drivers will not even be aware that it is there.
