I've calculated from the Doppler shift on this sound file that Schumacher was driving at about 276 kph.
Heigh-hoo tells me that the air temperature was about 14C, so speed of sound would have been about 340 m/s. He also tells me that it was Schumacher's first of 3 laps, which they usually take at about 270 kph. I know very little about F1 racing, so I had not made an inspired guess, honestly!
Frequency of approaching wave = 1867 Hz
Frequency of receeding wave = 1180 Hz
Average of the two = 1523 Hz
Speed of car = 340 * ((1867 - 1180) / 2 / 1523) = 76.7 m/s = 276 kph.
Raikkonen sounds to be going a little faster. Anyone care to calculate for that sample?
