Sorry to spam the thread, but here's an interesting method for measuring. I'm curious as well since I don't have my m40i yet!

To calculate your approach or departure angle, put your vehicle on a flat and level surface. Next, measure the height (h) and length (l). To measure the height and length, take a straight rod or board, wedge it under the tire from directly in front of the tire for the approach angle or directly from behind the tire for the departure angle, and then rotate it up unit it touches the vehicle. The location where it touches is the impact point. The length (l) is the measure from the impact point to the ground where the rod touches the ground wedged under the tire. The height (h) is the vertical distance from the impact point to the ground.
