Ok so you a bright guy. LEt's use common logic. You say this test is rigged:

Test in ams 1/2003Gewicht 1570 kg0 - 80 km/h 3,5 s0 - 100 km/h 4,8 s0 - 120 km/h 6,5 s0 - 140 km/h 8,5 s0 - 160 km/h 10,9 s0 - 180 km/h 13,7 s0 - 200 km/h 16,8 s
And yet on another continent a totally different US spec M3 ran 0-100mph in 11.2:

Bear in mind the US spec M3 has slightly less power.
