2012 Audi A8L: 5,000 Mile Road Trip and Serious Range

January 24, 2012


This Audi A8 has a laaaaaaarge gas tank. Audi says it will hold 23.8 gallons. Fuel mileage is respectable as well. As I reported yesterday, despite the EPA rating the A8 at 28 mpg on the highway, we averaged 23.0 mpg over the entire trip.

That gives this big sedan some serious range. As you can see in the photo above, the car's computer says it'll travel 610 miles on a newly topped off tankful.

After living in this car for seven days and 5,000 miles, I believe it. This car can easily top 600 miles per tank on the highway if the driver wants it too, and drives accordingly. If we averaged 28 mpg the Audi's 23.8 gallon tank should deliver 666 miles of range.

We didn't want it badly enough. Fact is, our bladders couldn't last that long. Also, when you're out in the middle of nowhere late at night, fuel availability can be questionable, so we would stop and fill up when we could. Better to be safe than sorry.  

Still, we did have two tanks over 500 miles, with the best covering 526.8 miles. When we stopped, the Audi drank 21.707 gallons, which means there were two gallons left and we had averaged 24.3 mpg. We also had nine other tanks cover over 400 miles with six of them over 450 miles.

This Audi is like a camel.
