I drive a Lumina Van, and it definitely gets it's best fuel mileage at 70 - 72 MPH. It has really clean aerodynamics, about the same as an F15 fighter, and is actually more aerodynamic than a Ferrari.
  • At 55 MPH, I get 27 MPG.
  • At 65, I get 29 MPG
  • At 70, I average 32 MPG and all the aerodynamic factors kick in, it develops it's best partial vacuum underneath, and settles down into the suspension and rides at it's most stable as well.

Drive for 40 minutes at a time, and you are doing 60 mph.

And yes, I have slowed from the mid 70 into the low 60s due to fuel costs.

Aren't there better threads for you to troll, or do you have to troll every single one of them?

My '98 Jeep Wrangler makes less wind noise at 50 to 55 MPH, so even before the the high gas prices, I would go slower when it would not interfere with other drivers; using less gas is/was a bonus. Lately, I have noticed quite a few pickup and SUV drivers, plus some car drivers, going 50 to 55 MPH, in the Houston area, and on night trips between Houston and San Antonio, the big rigs are moving slower than posted speed limits, around 60.

I spend a whole $2k a year on gas. I couldn't care less if gas went up to $8/gal; it'll only cost me an extra $2k. Heck, I'd love that a tonne as that'll mean there's fewer people on the road and I'll be able to get where I'm going even FASTER! Average for traffic around here is about 75. Los Angeles is about 80mph, but it's amazing that they do that bumper-to-bumper as well, no wasteful gaps between cars!

My Eagle was getting 22 at around 60, and that was with a big carbureted engine from 25 years ago, but I always drove faster than that, unless I was in town

Recently a reporter and an expert in high gas mileage both drove from Chicago to NYC. The reporter got there 6 hours faster and used an extra tank of gas. Six hours of my time is worth a lot more to me then the cost of a tank of gas. Driving primarily to save fuel can make you a road hazard, if not road kill.

Although, 22 or 28mph where the actual limit is 20 or 25 can't really be described as unsafe.

Choice of vehicle, avoiding the brake pedal, and accelerating more gradually makes a much bigger difference than switching from 65 to 55. On my current vehicle, the mileage isn't noticeably different, though years ago, it made a significant difference.

Fuel economy does not affect my driving speed, but I drive quite close to the limit. My wife has complained for years that I drive like an old man and that riding for me is boring. However, I belong to the school of thought that being a passenger in a vehicle should not be exciting.
