Why is the Mercedes E63 AMG BiTurbo lighter than the BMW M5 F10?

Becuase the double clutch? or just a smaller car?

95 kg difference?

I cannot believe it... The day that BMW's competition actually made a LIGHTER car. This should be reversed or be around the same..NOT having Mercedes being the LIGHTER one here. Wow...

it would seem Mercedes have "finally" got the measure of BMW, both power and weight wise sad day, they will get sales from BMW no doubt.

The biggest disappointment with the F10 is the weight

I thought they really would have made an effort to lighten the load. Not so...

I currently own a 2010 Merc E63 (not the biturbo but a 6.3) which is 10kg heavier than my last E60 M5. The Merc feels 1000 lbs heavier than the E60. I don't think weight is the ultimate baseline. I think BMW's really mask their weight because the driving dynamics are so much better than say a Mercedes.

For starters, the BMW is about 20mm longer, 20mm wider, and 15mm taller. The mercedes also has much smaller brakes at 14.2" front and back vs. what, 15.7"/15.6" on the BMW with 6 piston calipers front and back (Merc has 4 piston on back). The BMW also has slightly wider tires (barely), but it all adds up. Features and amenities on each makes a difference as well and could contribute to more weight on the BMW, not sure.

Are both measured with the driver? I believe BMW quotes their figures with a 75kg driver, is MB does not, that may be the difference right there

I say this as a current owner of S65 and M5.
As mentioned above, Mercedes AMG is a great vehicle.. well designed, attractive, very powerful, etc. However, AMG simply -cannot- match the driving characteristics of BMW M. The M is much more agile, and I agree that AMG even if lighter, feels much heavier. The driving dynamics vary and M takes the win. I still enjoy the comfort and power of AMG.. but always eventually (4-5 weeks) really want to be back behind my M.
