drove a friends m5 for about 15 minutes.
1) definitely more torque, not much, but through the rev range
2) more torque, but the cars a pig, so honestly, the speedo looked about the same as an e92 m3.
3) past 80,90mph don't even think about it. At that speed weight simply doesn't matter, displacement / horsepower wins. e60 m5's are ridiculous up top.
