I currently own a 1M but have never tried to push it to V Max as it is just going out of break in period, so the question is do the 1M reach 280km/h in speedo also?

The speedo's read +5% or so. This is bc of a German law.
A 1M will show 270ish on the speedo. Maybe 275 kph.
A 135i is limited to 250 kph. I know the German spec cars speedo reads to 280 kph, in stead of only 260 kph (160 mph) like the US spec cars have
On my US spec 135i(stock), the speedo would show 155 mph (250 kph) but the car only only traveling at 240 kph according to my gps. Now with my flash tune, my car can max out the speedo needle, and the fastest my gps has shown (or that I dare look over and read(!) while driving those speeds - is 283 kph. I am sure given more open road my car would go another 10 kph more. The German 1er forum guys say a tuned 135i will do 295ish. I think a 1M would do the same.
Here is a pic of my 135i stock at its limiter...
PS: It is important not to exceed 170 kph for the first 2,400 kms on a new BMW. This is not because of the engine but for the drive train, your diff can develop a gear whine under light load IF you do not ad hear to the break in procedure. I've had many German rental cars that you can hear that gear noise bc the renters never followed the breakin.
