The diffusers were a carry-over from both Can-Am, LeMans and F1, though their current form more closely resembles the early F1 diffusers.
The cars were bottoming out because there was no minimum ride height. At high speeds, the cars would generate enough downforce, combined with certain springrates, to lower the car. Also, through the late 80's and early 90's, the exhausts were routed into the diffuser to put more air through it and in turn generate more downforce. The problem with that was that when the driver went off the throttle under braking, or trailing throttle through a long sweeper, the downforce was reduced all of a sudden due to less exhaust flowing through the diffuser.
"The Chariot Makers" - is a great book by Steve Matchett about the evolution of the F1 car as we know it.
The exhausts were later routed through the sidepods for packaging reasons. It created a shorter exhaust system, eliminated the unpredictable downforce issue, and allowed the bodywork to cling closer to the newer & smaller gearboxes that were coming out.
But, one of the biggest things I miss about F1 is seeing cars screaming through the Monaco tunnel trailing a wake of sparks from the titanium skidpads on the wings & diffuser. |

So Kimi has a water leak in his engine which caused a pressure drop, and may prompt an engine change. I guess Todt was right when he said, Ferrari still needs to work on reliability.
Funny thing is, the article mentions that Ferrari told him to slow down (during aussi gp) when then noticed the pressure drop.
Now, how exactly do you write that on a pit board without letting everybody know whats going on? Either Kimi/Ferrari is lying saying that didn't have radio, when in fact they did, or the press is just getting things wrong. |

^^ There's no radio's this year? Pit-to-driver / driver-to-pit / both?
I know they banned two-way telemetry where the garage could alter the settings on the engine/diffs/gearbox from the pit wall, but I didn't think they banned radios.
Interesting!
I wonder how they signalled him then? Colour codes on the pitboard with his lead? |

I'm sure they'd have some code for the board to say slow down.
They'd plan for radio failures and have signals sorted for common instructions.
pmoisse - no, Kimi had radio failure. |

^^ Thanks :)
I was watching the race in Dutch and couldn't understand a damn thing lol
For the next race I'll log on to the official FIA live timing. |

I'm warming up to the control ECU concept after hearing this.
from www.f1live.com
The World Motorsport Council met yesterday and the FIA today announced the decisions that were made with regard to the sporting and technical regulations for next season.
The most significant change to the previously published set of rules is that traction control will no longer be permitted.
Article 9.3 of the technical regulations states: ‘No car may be equipped with a system or device which is capable of preventing the driven wheels from spinning under power or of compensating for excessive throttle demand by the driver. Any device or system which notifies the driver of the onset of wheel spin is not permitted.'
Formula One moves to a standardised ECU next year and it now felt that the FIA can effectively police traction control and other driver aids, something that proved difficult with each team running its own ECU and electronic systems. In addition, the FIA ECU must also be used in testing.
With gearboxes sealed and to be used over four Grand Prix weekends, a change of gearbox will incur a five position penalty on the starting grid.
However, the seals can be ‘broken’ under supervision of the FIA in races two, three and four ahead of qualification for inspection and the changing of ratios. Clutches can be changed without penalty.
With regard to engine homologation, there are many ancillary devices such as clutches, alternators, fuel pumps and other devices that are not included in the process.
Other rule changes include the procedure for taking a penalty in the pit lane should the safety car be deployed, changes to the crash test requirements and crash structures, and clarification of the engine change rule regarding a failure before the end of qualifying.
The much-rumoured return to slicks meanwhile is not an option now for 2008 with the Bridgestone Potenza tyres remaining with four 14mm grooves. |

I like the new tyre markings, it gives a whole new look to the car
I'm pissed i probably won't be able to watch the race live
:mad: |

I'm in approxiamtely the same time-zone as KL, and our channel who proclaim themselves "The home of motorsport" aren't showing the race until 11pm tonight. What they are showing now while the race is on is.................. City Slickers 2 - The Legend of Curly's Gold.
EDIT: Billy Crystal just made a joke that wasn't funny. |

I finally watched most of it live. Good job Hamilton, he kept his cool and powned Massa . Tough luck Kubica
,I wish he finally had a car that worked. |

No kidding. A true star. Although I have never believed in Massa, this kind of proves it. Hamilton just ed with him, until Massa threw himself off the track.
Impressive stuff from McLaren. Where the hell did they come from? |
