BMW has officially announced 4.4 seconds as the new M5’s 0 to 60 mph acceleration time. But American magazine Car&Driver has arrived at a different number.

Now, you would expect the number the independent testers achieved to be higher than what the huge, faithless car maker claims. But it isn’t! Staggeringly, the time is much quicker than the official performance figure BMW has announced.

C&D tested the M5 the other day and recorded a 0 to 60 time of 3.7 seconds. They also posted a quarter mile time of 12.0 seconds at 122mph.

We know BMW likes to underrate performance of its cars. But underrating 3.7 seconds is 4 seconds, not 4.4. That is a big difference. Why would BMW do such a thing? Is there a chance C&D equipments are rubbish?! They’ve also measured CLS63 AMG’s acceleration at 3.8 seconds, while it should be 4.4 seconds.

4.4 seconds 0-60 time is fantastic for a four-door saloon. 3.7 seconds is just plain awesome. This new M5 is a phenomenon.
