For all we know, BMW may have sent this publication a modified one. Apparently, it may not be the first time. For all we know, they clocked 4.3999 seconds but decided to round it off to 4.3. For all we know, at the testing grounds they got 4.501 but rounded off to 4.6.

Some days my current car vibrates first thing I turn it on and honestly some days it smells like it is burning unusually rich. Maybe some days, cars run better than other days. I'm no expert

This M2 won't come out till well into 2016, so it will be easy for slight performance bumps for the 2016 m3/m4 to avoid a potential estranged relationship between models. A consistent, 4.1, would be a pleasant surprise.

Cars will run better times on different days for sure. Atmospheric pressure, temperature of the air and road surface, moisture etc etc etc all play a part in a vehicle's performance.
