You should not be surprised. I recently test drove a new GTO (manual) with a
tight engine and took it for a spin at 70 mph (flat road, cruise set) . The mileage meter showed 25 mpg, a little under the EPA estimate. We had a 1992 LT1 (300 hp) Corvette and it could deliver 30 mpg @ 70 mph all day. The aerodynamics of the Corvette are far superior to the Magnum. Plus the Corvette barely turns over idle in top gear at highway speeds. The thing is such a torque monster it just does not need much in the way of rpms to go fast. The really interesting designs are the GM OHV V6's. These things are ancient (but very refined) designs and make good power and get fantastic mileage. A friend has a new Impala and just got back from a long highway trip (car loaded with stuff and family) and got 30 mpg averaging about 80 mph. The V6 in the Malibu makes more power and gets better mileage than the Japanese brand high-tech 4's!

I have an '03 3/4 ton with the hemi, and it's getting about 17-18 in high speed freeway driving, like around 80. In town, the mileage is much worse, between 12 and 13. I read a writeup in Car Craft on the '04 hemi. It turns off 4 of the cylinders when the power isn't needed. I don't think Dodge would put that system in a truck. I think the greater wind resistance and weight would compromise its usefulness. Ken |

I don't consider that too surprising. A friend of mine has an '01 Trans Am with the six speed, and on a trip last year to LA, he averaged 28 mpg. It's that steep overdrive in sixth; the motor runs barely above idle.

Plus, it sounds like there is a lot of leg and head room. I'm 6'4", it'd be okay for me? |
