Webber Criticises Safety Car
Discussion
I thought Boyle's law was the link between pressure/volume/temperature? Namely...pressure is proportional to temperature, inversely proportional to volume, and volume is inversely proportional to temperature?
Hence, the links required from above are pressure vs temperature...namely, temperature is proportional to pressure.

I wonder if they should consider using race cars from lower series as safety cars rather than tarted up road cars. At least that way they could keep the speed up around most of the circuit and then just enforce the reduction in speed through the area of concern. Of course that would limit the possibility for the sponsors to get one of their cars out on track for some prime time TV though so will never happen...

Saying that tyre "pressures" drop becuase of the low speed it crirculates at. I thought the problem was that the temperature of the tread drops not pressure as Nitrogen is used to fill the tyres?

Nitrogen is used as it contains fewer water molecules than air. It's the water molecules that heat up and increase the pressure. Nitrogen with it's fewer water molecules means the pressure increase is greatly reduced and so it's easier to keep the set-up of the car stable. Most forms of motorsport use nitrogen for this reason, it's certainly something that we use.
"For its demanding assignment as the Formula 1 safety car, the SLK 55 AMG required modifications that were few in number but very sharply focused. The distinctive sporty strengths of the new two-seater developed by Mercedes-AMG were only supplemented in areas that would generate maximum high-performance and reliability for circuit operation. In place of the standard 18-inch tires, for example, new multi-part 19-inch AMG light-alloy, double-spoke rims with special 235/35 R 19 and. 265/30 R 19 tires have been used. And together with the firmer chassis tuning, the car can handle higher curve speeds and has even more agile handling.
The enhanced performance of the new, enlarged braking system ensures that the car remains perfectly stable and exhibits optimal deceleration. Composite brake discs with six-piston brake callipers are installed on the front axle, and internally ventilated and perforated steel brake discs with four-piston callipers provide the stopping power in the rear. Channels that direct cooling air to the front brakes - which have to bear particularly high stresses - were specially engineered for the safety car’s use in a racing environment.
Weight Reduction
In order to deliver world-class racing performance, the weight of the safety car was trimmed by nearly 100 kilograms (220 lbs) in contrast to the series-production vehicle. And this was achieved despite the fact that the car became heavier right from the outset because of its added components - including communication equipment, lights, cooling systems for the rear axle and brakes, and larger wheels and brakes. The safety car has a curb weight of 1,370 kg. In comparison, the curb weight of the SLK 55 AMG series-production vehicle is 1,465 kg (not including the fuel and driver).
Engine and Drive
The engine and drive of the unique Mercedes-AMG SLK greatly resemble their series production versions. The 5.5-litre V8 engine from AMG delivers 360 bhp and accelerates the silver two-seater from 0 to 62 mph in under five seconds. What’s more, its convincing eight-cylinder sound is sure to appeal to racing fans watching at the track or on TV. The sports car was given a newly developed exhaust system with reduced back pressure and a special sound for Formula 1 use.
And to ensure that even the toughest of weather conditions are no problem, the SLK 55 AMG safety car is also fitted with a high-performance water cooler, two engine oil coolers in the sides of the front apron and a larger transmission oil cooler. The rear differential has cooling fins and a separate cooler installed into the rear valence. The air stream is distributed through it by a diffuser, thus helping to prevent the rear-axle oil from overheating. When the car is stationary, an electric fan is employed to increase safety even further."
Although the uprated disks etc help, I don't think 360bhp cuts it. Although 0-60mph in 4.9 is quick, I don't think it cuts it...it could be better IMHO. Needs more BHP say 500 and less weight.

the main upgrade is the boot full of fresh £50 notes that mercedes supplied it with.
