Subject: RE: Explaining 80 mph to Wife !!!!????
How good are the tires on the car? Are they properly inflated? Are the wheel bearings "up to snuff"? What about the road surface? How about the aerodynamics of the vehicle?

80 mph is a figure supplied by the vehicle -- is the speedometer acccurate? The US government allows a variance of up to 10%.

In brief, there's not enough information to give an accurate answer.
