0-60 3.6sec? 3.8, 4.4 or 4.6?

So in this car & driver review w/ launch control they said 3.6 seconds which is pretty damn fast.

In the same review they said 4.6 w/out

Official specs say 4.4 from BMW, not sure if it's rolling or launch.

they also did a test originally stating 3.8 seconds

So which is accurate?

All of them. Different surfaces. Different temperatures. Different tire wear, etc = different times.

i hear in America 0-60 times are timed using the 1 foot rolling method which in itself helps to gain at least 0.2sec.

Here in the UK, it is mainly 0-62mph (to make it 0-100kmh) and from a complete stop. It may explain some of the differences.
Autocar en EVO have 4.5sec and 4.4sec resp.

There is also launch control which will probably knock a couple of tenths off, too. The test fleet may not be as good as the cars out there now.

I suspect that the car will do 0-60 in 3.6 but BMW doesn't want to advertise it. And 60 mph indicated in the car (which we won't use for measurement purposes, of course) is really 58 MPH. Current BMWs are all 2 MPH over. At least that's true as to the 4 I have now and the previous 5 going back to 2006.

I suspect that the car will do 0-70 in 3.6 but BMW doesn't want to advertise it. And 60 mph indicated in the car (which we won't use for measurement purposes, of course) is really 58 MPH.

Yeah, quoted 0-60 times for German brands are usually what you would get under the worst possible "normal" conditions (at 10k feet and ice cold tires).
