What is this discussion about?
Audi Q7, SUV

Oct 23, 2009 (1:52 pm)
My first almost all highway trip.
511.2 miles with 23.7 gal of fuel, i.e. 21.6 mpg, which was exactly what car computer also said. Driving was about half at 70 MPH and rest of it mostly 60 MPH with some slow town traffic.
2nd full tank 170 miles going 78 MPH and 70 miles at 60 MPH and another 15 miles at 50 MPH. Total 255 miles and car computer says 20.8 MPG, fuel gauge at half mark.

Replying to my own message.
Today road trip of 331.5 miles.
Filled up before trip. Drove on Interstate Highway almost all the way at 78 MPH speed on 70 MPH limit. I had 82 MPH in speed meter as my Q7 obviously has 5% meter error, i.e. speed is 5% less than speed meter shows.(I have verifies this with my GPS that has very nice speed reading. At 40 MPH my speed is 2 MPH less than meter reading, at 60 MPH it is 3 MPH off and at 80 MPH it is 4 MPH off.) Only about 12 miles of my trip was at 72 MPH on 65 MPH limit.
Car says 20.4 MPG. Fuel gauge says 3/8 left. This would be very close to 20.4 MPG just like car says if indeed 3/8 tank means 5/8 (16.25 gallons) was used of 26 gallon tank capacity.
