Hi guys! My brother went away for the week and gave me his 06 M5 to play with. I noticed the "M" button on the steering wheel and the "POWER'' button on the console. What is the difference between those two? also when I am driving and I push the M button in SMG mode I notice the car jumps too. Is that normal? Also when I have the car in automatic mode will the M button work or only in SMG mode? Over all I love this car a lot! I noticed the power in the E60 and my 00 M5 is night n day! I have never driven anything more powerful!
