Not sure what site this is, but this is where I found this info eartheasy
I don't doubt that it's true, just that I'll never go 55 again. Road Rage will be all the rage.
Strange enough, my past 5 cars have all gotten their EPA hwy rating at 80mph. I'm sure that they would have gotten better mileage at 55mph, but I'll never know.
When I first bought my new car last fall, I was generally traveling 60-65 mph on my long commute to work. More recently, I've been driving 70-75 mph. I've noted that I'm getting better gas mileage than before, 25.8 MPG versus 25.3. I attribute this to the higher speeds. Of course, my vehicle is European (BMW) so it may be calibrated for better gas mileage at the higher speeds than an American model.
I drove an average of 80-110 mph in Germany in a Ford Mondeo over 3000 km and got a mileage of 38 mpg.
Are you seriously suggesting I'd have gotten 50+ mpg at 55 mph?
It's an environmentalist site.
They can be trusted to give us accurate information regarding gas mileage, pollution and a return to the dark ages.
HIGHWAY gas mileage stickers are actually quite accurate.
Whatever they post on the sticker for highway speeds is tested at HIGHWAY SPEEDS... often 75 mph or so.
the 55 lie was a carter era attempt at cooling down the nations economy, cars were not aerodynamic as they are today, nor were they geared to wind as tight....
things are a LOT different.
the data being posted at enviro sites is propaganda.
