hmm.. if i had an exhaust system that had SOME flow.. i might would be able to get better mileage.. but that.. SHHHHHHH..idle sound cant be good..

i guess i'll have to save the money myself for the exhaust..even as much as my dad talks about getting it... :pound:

wow... Though I hear that driving behind a semi truck exponentially cuts down on wind resistance? Do you like to draft? lol

I do that every so often. It seems to lessen the throttle requirement, but I haven't done any real mileage tests. The highway to my parents place usually doesn't have many trucks, but the expressway around the city is full of them and I usually tuck in behind a truck when I'm on it.

my grandpa will claim it anyday.. in the late 80's -early 90's he sold neon ( yes i have some..and still have 30 boxes of assorted chlothes left) and he drove a VW bus to the beach where his stand at the flea market was.. 2 hour drive he could make it there and back using VERY little gas..due to drafting that big ol van behind a 18 wheeler.. he claims he could let off the gas and it would pull him to it..  :roll:

What you need to do is bolt a periscope on the hood horizontally so you can tuck in behind the truck and still see what's going on in front of him. :D

drafting a semi could possibly push the 25mpg I saw to 30.  IIRC the 5th ave's have a high drag coefficient (above .45CD, iirc).  and this spring, on a trip to MN, I was drafting a straight truck in our '06 caravan, doing 70mph and was averaging 30-32mpg on the fuel economy computer, where we normally get ~27mpg doing the same speed...

Fascinating. And the best mass produced hybrid gets what? 46mpg? And our cars are like 25 years old? Hybrids leave alot more to be desired for me...

Anybody ever driven a hybrid? It's an odd experience. The Prius basically drove like a regular car, albeit with a nifty display. The GM hybrids are pretty neat, the only extra crap they pack into the interior is a charge/assist gauge, and they use regular production cars so you don't have an ugly car. The thing about GM's hybrids is if you let off the gas, they engine brake like hell, almost like having real tall gears. Of course, it's not the gearing, it's the regenerative braking kicking in. The braking is odd feeling too, because the actual brakes don't kick in unless you're at low speeds or standing on it. Otherwise, most of the braking is accomplished by engaging the electric motor as a generator. Real nifty design, originally they used it with diesel/electric locomotives to great success.
