I hear the motor running in about every vehicle I drive...ranger, focus, crown vic, chevy van, caddilac (although very soft except in acceleration), impala, lets see, what else have i driven in the past...oh yes, a charger, a ford mondeo (in europe) VW passat, alfa-romero (in europe), F-150, mustang, caliber, mazda 3, forte (the list goes on, but I'll stop here)....yep I've heard the motor run in all of them...
Now, if there's a lot of ambient noise it may be hard to tell if the motor is running or not, but normally, I can hear the motor in everything.
