not really more efficient. Sure, they can say rightfully that their car gets more miles per tank full of gas but that doesn't mean much considering their tank is bigger which means they'll pay more because they will be buying more gas to fill up the tank.. however all in all i bet the newer ones do get better mileage than our sweet oldies. But that'* still cool in my book.

I do think the new cars are somewhat more efficient, but not enough to warrent replacement. I drive a different GM car just about every week - my current preference is for 2-door Aleros with the 3.4. Earlier in the year I had occasion to drive from DC to Clarksburg WV and back in a 3.1 Buick Century (Avis has a lot) and averaged over 30 mpg for the all-Interstate run each way.

Did average over 30 mpg in the Bonne once but that was when new and no a/c also. Today, my wife usually gets 17-18 mpg aound town so the oiginal spec wasn't far off.

Does seem like I get the best MPG in the 50-60 mph range but I rarely drive there and it drops somewhat as the speed increases.

Even so I doubt that many want to drive over 5 hours/350 miles without a rest stop.

When I had my 89 SSE, with 438,000KM on it- it got 600 KM to a tank of gas, but one time I got it to 620

Newer bonnies might get better gas mileage mainly because the engines and subsystems have less mileage. Almost any machine becomes less efficient with age and use.
