What are the hypermile "sleepers"

However, the Nissan 240SX 1989-94 or the 1995-98 are very sporty looking, and can get good FE. They are also RWD, so they really have that sporty feel, but they are not so good in snowy or icy winters. On my 91 240SX I get about 30-32MPG just driving lightly, no hypermiling. Even when racing often I still got around 20MPG.

the toyota paseo is a good car for fe my ex had one it got great mileage and she could not kill it.

i don't trust the dash units in any anything

I agree to a certain extent. I've seen a Dodge quad cab pickup truck that was pretty accurate. I've also seen a 2006 Chevy Suburban that it's fuel economy display was very optimistic.

If you want a hyper miler get a turbo diesel car and run it on corn oil.

In fact I am surprised that few of you guys are not talking about LPG conversions and buying veggie oil for your diesel cars, how come?

My high-revving naturally-aspirated 2.0L powerplant makes 100hp/L and returns about 33mpg average, beating the EPA combined estimate by 43.5%. My best record is ~44mpg on a 35-mile highway trip.

The key is that my engine makes almost zero torque.

My Mustang returns a consistent ~33mpg on the highway, and I have yet to lower, add headers, or UDP. I'm gunning for 40mpg @ 65 Unrealistic? Yes! But I'm interested to know what I can do.

My average down there would be a whole lot higher if I could keep my foot out of it in-town, but I can't. This thing's exhaust sounds too mean!

C5 Corvettes get even better mileage than the Camaros, since they're lighter and slippier. One gent over there's got a cammed LS6 putting 385rwhp to the ground and gets a constant 35mpg on the highway.

I agree with you completely. My Wagonstein (3.2L cammed and turboed V6 Cavalier Wagon) has a mean sounding exhaust with a nice lope to it. In town it's hard to keep my foot out of it. The last tank of gas was just over 23 mpg in town. I lowered my rev limit to 3k and lowered max boost to 2 psi to help force me to get better gas mileage in town.

I think the trick there is the BSFC/load thing, since torque is low the engine is very highly loaded at all times, resulting in low BSFC

Hey, I could do that! Thanks for the idea!

(watch as my in-town gas mileage skyrockets)
