The question is - how much extra gas is burned in an hour traveling at 80 versus 65.Our cars get better than 25 miles per gallon but let's assume it's only 25 freeway. So hypothetically - that's an extra gallon burned going 80 versus 65. So that's an extra $4 that is burned up going 80 versus 65 every hour traveled.

That also means within one hour, at 80mph speed, you travel 25 miles further.

If you drove slower at 65mph, you would've had to travel longer. That means you'd have to travel another 23.08 minutes for the extra 25 miles further.

So although you burned extra $4 worth of fuel going 80mph, it's offset by the fact that you'll go another 25 miles traveling longer, using up more time and more fuel at 65mph.

So back to what I was saying: it's the same damn thing in the end. So if I'm going to use up same fuel traveling, I might as well get there faster.

Also - at both 65 and 80 mph, our v6 engines are not revving above 3000 rpm at any time. This means we're pretty damn efficient and the engine is pretty idled compared to other v4's that are at 4000 rpm around 75 - 80mph.
