    Henry,

    You are right 25 mpg is a joke (this figure is mostly due to what Eric mentioned in an article he had last month about the skyrocketing weight of cars). As a comparison in late 1983 Chevrolet released the L69 (190 horsepower) 4bbl 305 H.O. V8 powered Z28 Camaro which was one of the fastest cars in America back in 1983 it did the 1/4 mile in 15.55 seconds and 0-60 mph in 7.41 seconds. The 250 horsepower heavier 2009 Challenger SE V6 probably will be close to these figures and it will get worse gas mileage with fuel injecton, good gearing, and a small displacement V6 than the lo-tech 1983 L69 Z28. The '83 L69 Camaro Z28 had 5.0 liters of displacement, a 4bbl carb, and 3.73 rear gears yet it got 27 mpg on the highway (checkout the below attachment from MT June 1983):

    Nice find. those numbers were the raw numbers used for the window sticker from 1975-1984.

    For the 1985 model year, they adjusted the inflated highway and city gas mileage figures by 10 and 22 percent, respectively. They still retained the old tests to validate manufacturers compliance with CAFE. That still holds today.

    In 2008, they changed the test to reflect higher driving speeds, increased suburban driving, and use of air conditioning.

    Even with those adjustments, that 25 mpg figure quite literally sucks. A 2007 Vette gets better real world mileage.

    Saw a SRT8 on the way to work, in heavy traffic. At 50mph, he probably was getting 25mpg.

    as a note: most corvettes (c5 and newer) can easily break into the 30+mpg range on the highway - I regularly hit 34 with mine.

    Which is just amazing when you stop to think about it... .

    Old tanks like mine - with bigger engines that make less power - can barely break into the high teens. On the highway!

    Damen,

    Do you have an aftermarket air intake/box in your Vette? It's my experience most C5 owners who get gas mileage close to what you're getting usually have an aftermarket air intake/box.

    The key to the Vette's great gas mileage is its light weight, good gearing, fantastic aerodynamics, and very sophisticated fuel injection/compter engine management.

    I do now have an aftermarket intake, however I was getting about the same mileage even before then. It should also be noted that I have the automatic transmission, not the manual

    The 'Vette has a very steep 6th gear OD ratio that drops the RPMs to just over idle speed (around 1,700 rpm) at 70-something mph... it is really something!

    Eric,

    Just out of curosity what are you getting in highway mpg on the new LS3 in your Corvette test car? And how many miles are on the odometer of you test car?

    Not sure - I'd have to fill the tank, then drive say 50 miles, refill - and do the math... as far as mileage, will check the odo and report back. This is an automatic convertible, fyi.

    Also - they just left me a V-10 Audi S6.... gun metal grey and super discrete. Much prefer it to the cop magnet Corvette!
