Pete - 280bhp engine output. I think 180kph is actually 112mph to be precise.
Kid - You say no restriction but then say most are limited to 130... we are talking about cars which are electronically limited to speeds below their capability, not limited by their power.
Mercs are euro cars..... euro policy is 155mph (250kph). I don't think there is an actual law about this but it is a kind of unwritten agreement between (most euro) car manufacturers and the european government inline with safety and environmental issues. (I'm sure there is a bit of "you scratch mine and i'll scratch yours")
I believe Japan is different... 112mph (180kph) limiters are the LAW. sucks huh?
Interestingly, Audi limit their cars at 175mph(280kph)....... Porsche don't......... Neither do Ferrari.........
If a japanese car is imported to the UK, it HAS to have the ECU reflashed to alter the emissions... the delimit is a small bonus.
