We know the new M5 puts out a ton of power (527 rear wheel horsepower) and is capable of running 11's in the 1/4 mile in stock form. So what gives with Insideline acceleration testing hitting basically E92 M3 level acceleration figures running a mid 12 second 1/4 mile with traction control off and a 13.8@110.6 with traction control on?

The manual transmission and a poor launch explain it. Seems they struggled launching the car a bit but were not far off what others have achieved. These are the slowest acceleration test figures posted thus far but only off just over 1 mile per hour in trap speed versus what Road and Track hit with the manual which was 12.3@116.7.

Road and Track hit 11.9@119.7 with their dual clutch transmission car matching what IND-Distribution was able to achieve at the drag strip as well with their dual clutch transmission car. Why would anyone would still doubt how much faster the dual clutch transmission makes the car? If one demands the absolute fastest acceleration performance out of the F10 M5, the dual clutch is simply the better choice.

Test Driver Ratings & Comments
Acceleration comments A little tricky to launch. Either gets lots of wheelspin right off the line, or no wheelspin initially followed by lots of spin shortly thereafter, requiring a bit of backpedaling through 1st gear. Nice power, if an odd V8 engine note. Shifter has kinda long and rather notchy throws but well-defined gates.
Braking comments Very firm pedal, short travel. Car barely dips the nose at all and stops are incredibly stable. Still, how embarassing that the VW Up! stops shorter. First stop was shortest at 111 feet. Fourth stop (out of seven) was longest at 117 feet. Erratic distances.
Handling comments Skid pad: Even with the suspension set to its stiffest at Sport Plus, the M5 rolls over mightily on the outside front tire. Dialing back throttle lessens the understeer, but certainly doesn't eliminate it. Overall, grip is pretty good though, definitely better than the old car. Slalom: The M5 is too soft, even in the Sport Plus suspension setting. Surprisingly, the hydraulic steering felt best in Comfort mode -- Sport and Sport Plus feel heavy for the sake of being heavy, but don't give any increased feel or quickness. The chassis gives decent feedback and the M5 is very forgiving at the limit, but the overall sensation is one of massive weight transfer. This is definitely not a car that drives small, and no one will call it nimble.
