[V8] Mileage/adaptive tranny?

[Scott Simmons]

An 18mph crosswind leads to a 2mpg penalty, while an 18mph headwind will 
produce a whopping 17 percent penalty.  On the other hand, an 18mph tail 
wind results in exactly the opposite: a 17 percent increase in fuel economy.

In terms of temperature, an ambient temperature of 50*F will cost you 5 
percent of your fuel efficiency, while a 20-degree day is good for an 11 
percent penalty. 

Driving at an altitude of 4,000 feet above sea level will cost you about 
15 percent of usual mpgs.  Conversely, driving at 4,000 feet below sea 
level should provide a boost in fuel economy, but I don't think it's 
ever been tried.
