sorry if i offended the professional drivers.... in this case i had the camera Zoomed 2x to get the DIC information and actually I had about 1.5 -2 spaces between me and the truck as you can see there is a bit road in front of my ... not only his bumper. About 10 miles back he pulled from the slow lane passed me then I flashed my lights to let him back into the slow lane.... he gave me the "all light" blink as a thanks that's actually when i started to notice the fuel improvement.... Granted there are some bad drivers out there please dont bash me till ya know all the facts...

OMG what a silly thread... at 70 MPH, you should be about 7 car lengths in order to maintain control in a panic stop. The corvette is not a Box, and is , by its very design a very slippery machine. Driving at 70 should yield an unprecidented 28 to 33 MPG. anyone thinking they can save 1 mpg and run the constant risk of killing yourself is an idiot.
1 mpg @ 70 mile per hour represents 1/30 of a gallon of gas or 8 cents.

boy
Man .... Again.... just something i noticed .... I am not saying go out and draft anywhere on the streets ... I merely noticed this when a truck pulled in front of me in my right lane and thought to myself "wow" "cool" look at the instant MPG change when he pulled in my lane. I figured i would break out the camera and capture it..... Please calm down ... This is not a recommendation to draft, tailgate, perform unsafe traffic violations or violate any laws ... It was just something i noticed on my way home last night while on an interstate and I thought i would post it to the forum....

Are you sure the RPMs remind 100% constant, because I would think the cruise control would bump it up 25-50 rpm to compensate for the turbulent air coming off the truck. That would result in a temporary drop in mpg. Did you happen to run for a while in the outside lane to see if whether or not the mpg came back up at all?

In fact, all the wind noise will go away and you will be sucked up to the truck if you do not back off the throttle.
Don't tell the NASCAR guys.

Anyway ... Good question did not take note of that...

I looked at the RPM several times but it's difficult to tell from that vid. I noticed tonight on my way home from the beach just relaxing a hair on the throttle will drop the MPGs.
Either way aren't you suppose to be right on the bumper to be drafting! Even with my '01's bra on I would stick the nose of mine very close to a truck. But cool experiment.

Cool observation none the less.
