Because it's 250kph, which seemed about right for "reasonable" autobahn use.
Some are limited to 186mph, because that's 300kph.
And no, it's nothing to do with any form of legislation, it's a self-imposed limit manufacturers use.. Think like the 280PS "limit" Japanese manufacturers had in the 90s to stop themselves going silly. A lot of 155mph limiters are about as liberal as that, too

To appease the Green party in Germany It also tends to be fairly flexible, my S4 gets to around 160 (GPS verified) before the limiter kicks in.
It's called 'voluntary industry restraint'. What it means is that the industry believe (or the government implies) that if they get into a marketing war using top speed or power figures, then the government will feel compelled to pass restrictive legislation (either an outright limit on top speed as in Japan, or a tax as on high power outputs in Italy).
Therefore the industry voluntarily agree to either a) not disclose or b) limit their vehicles' power or top speed.

The competition to create the fastest production motorcycle ended in a truce, after just over a century of one-upmanship by motorcycle manufacturers that began with the 1894–1897 Hildebrand & Wolfmüller[1] and ended with the 1999–2000 Suzuki Hayabusa.[2][3] A gentlemen's agreement was reached among the major motorcycle manufacturers to limit the speed of their machines to 300 km/h (186 mph), starting with some 2000 models, and becoming widespread by the 2001 model year.[1][4]
After the 1999 Hayabusa sent shockwaves by exceeding the Honda CBR1100XX's record by more than 10 mph, and rumors and leaks from Kawasaki hinted that their upcoming 2000 Ninja ZX-12R would pass the 200 mph milestone, some regulators and politicians in Europe called for an import ban against high speed motorcycles.[1] There were fears that there would be, "an outbreak of illegal racing as riders try to break the 200 mph barrier."[5][6] To preempt regulation and avoid negative publicity, the manufacturers voluntarily ended the race to ever higher speeds.[1][4]

The German manufacturers have such a voluntary agreement to avoid home market legislation (especially autobahn speed limits). However, it's a fairly fragile truce, with Porsche not taking part, competition to see how much 'tolerance' manufacturers can add, and various 'special options' to lift or remove the limiter at extra expense.

As others have said, voluntary agreemnet in Germany. Among other things it saves the serious manufacturers needing to engineer aerodynamics which can cope safely with higher speeds.Remember the Top Gear koenigsegg incident?

My car is limited to 155mph. Some eggheads have looked at the stats and reckon the gearing will go to 186mph. I want to know what the top speed actually is. I guess somewhere north of 155mph and south of 186mph! At 155mph it feels like it still has more to give. It's working hard enough, but it will easily work harder.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
