Thread: More fuel economy woes.. 2004 2005 GTP

Sounds about right to me... These aren't advanced fuel sipping cars, they're inefficient, heavy, powerful cars designed when fuel was ~$1.00 a gallon. My 99 Regal got around 19 mixed, with a max (road trip) of 28.

True... they are not exactly designed to be misers on fuel economy, but I get nowhere near the rated economy. Also, I had a carb'd, 84 Z28 with a 5 speed that would get 31MPG on long trips. To be sure there's been improvement over the subsequent 20 years between production! Especially with a fuel-injected V6 having only 75% of the displacement of the 5.0 (H.O. no less! haha. 195 HP! lol). But, what SHOULD be capable--power and economy-wise--from this 3.8 is not the point. The problem is that it doesn't come near what it is reported to do, factory or otherwise. :-\ Most of the time, I don't even average the estimated city number with my combined 30/70 city/hwy.
