rpm question
 

hi everyone..speaking of rpm's..i have a 2005 x5 4.4 with 17k..i noticed since i got it that at 60 mph it is turning 2000 rpm but most other cars turn at 1800 rpm at 60...is this normal..i found that at other speeds it is also slightly more than other cars that i have owned..this is my first bimmer and i have nothing to compare it to....thanks rob
