The M6
Basically the same thing with the M5, except with the M6 you can’t even carry extra adults. Well, okay. You can but the people sitting in the back seat aren’t going to be happy about it.
On the plus side, Efficient Dynamics means you’ll be able to drive longer, faster, without having to stop for gas. The fact that it can get from 0 – 60 mph in nearly four seconds and not be out of gas by the time you roll out of the driveway is a testament to BMW’s technological prowess.
