Default MPG at 100mph

2002 WS6 A4 On the Vette you can see what your instant mileage is. Has anyone with an A4 ever checked it at 100mph?

I know this does not answer your question. But a 2002 ZO6 mileage breakdown is as follows:

60mph.....30mpg
70mph.....27mpg
80mph.....25mpg
90mph.....22mph
100mph....20mpg

FWIW, I have set the cruise at 130mph and was getting 16-17mpg!!!!!!!!!

Yep, it drops quickly. Remember, you have a V8 under there. GM geared the whole rig to do well for the EPA profile....which I guess is around 60mph.

There are some roads around here that are long and relatively traffic free. I didn't leave the cruise on that long. I just wanted it to stabilize and see what the MPG was.

Default Re: MPG at 100mph

I just drove from san antonio to houston and back last week, and on the way from san antonio to houston, i ran between 90-100 all the way there(with the top off), and got around 23 mpg, and on the way back, i set the cruise on 70(with the top on), and got 31 mpg ...these cars get great mileage. This is on my 99 coupe with a few mods.(but still has the 2.73 geared auto

Default Re: MPG at 100mph

Hey, that's not cool. I average out around 250/60 MPG on a full tank in the city and freeway. Is there something wrong with my rig? I wish I can do 400 miles on a full tank!

Default Re: MPG at 100mph

It doesn't drop that fast because you have a V8. The fact that horsepower consumed by drag increases in a cubic fashion in relation to vehicle speed has a lot more to do with the MPG

Default Re: MPG at 100mph

I averaged 78 mph from Atlanta to Bowling Green and 28 mpg. This included one stop north of Nashville for breakfast and one stop at a rest area.

Gas milage depends on several things.

Default Re: MPG at 100mph

I've taken a couple 1000 mile trips (one way) and usually got 31mpg at 75mph. About to run the same trip in a couple days, but for the first time with all my mods. Hopefully I get the 475 miles in one tank again!

I averaged 29 mpg on my cam only C5 M6 driving to Iowa and back. Over 2500 miles round trip, many miles were driven 80-90 with the cruise set on 100 in some places.

18.6 MPG from Corona to San Jose at an average speed of 89mph, with a peak speed of 175, and 20 minutes of breaks and refueling. It was quite a ride. I left at 3am for a meeting that started at 8:00am, and arrived 45 minutes early. About 375mi.

I'd probably get 10 mpg at 100mph since I have a A4 with 3.73's.
