I just got my Aurora and how do i know if i have the autobahn package?

1. Check the tag inside the door to see if the original tires are V rated.
2. Look at the RPO list (under the spare tire cover) and look for code FV4, that code means a final drive of 3.71.
3. Drive the car at 135 mph.

Any "yes" tells you that the car has autobahn . . .

Pull up next to a nitrous Honda at a dead stop, stomp throttle when light turns green, nitrous Honda will move slowly one car length in front of your door somewhere between 45 and 95 mph then suddenly at 100 MPH you will power by nitrous Honda and then see a complete rearview mirror image, generally the front of the Honda will be visible, at this point, more than likely, you have autobahn.

That sounds like fun, but the RPO code check is the best way ;)

go over 105 mph on the hwy with no one around at 1 in the morning
