We had a 2010 X5M and now have a 2014 RR sport V8 supercharged. Driving both back to back has me convinced the RR was just as fast as the X5M. Handling isn't great but is close when you put the RR in dynamic mode. I can't imagine how the SVR will be. This motor has gobs of torque and the sound it makes is soooo evil!
