I have wondered about this question as well. You delve into the relative safety issues of various size cars and SUVs, but do not answer the question directly.

For example, I have a 1986 Toyota Corolla which gets a consistent 39-41mpg on the highway. My friends with new Corollas rarely get 34mpg on the highway. I don't think their driving habits differ substantially from mine, i.e, they do not drive at 75mpg while I'm chugging along at 55, etc. With supposed "better" technologies, seems they should be doing better than me.

Of course, to answer this question, one would have to compare quite a few models and have better data than my subjective collection.

Please leave the SUV's out of the equation, as I don't think they pertain to the question.

Any thoughts?

Byron hit it on the head. Please answer the question as to why today's subcompacts get such poor gas mileage compared to the predecessors. Also, we all know that the EPA MPG is never achieved.

Aye..... I wonder about this too. My '91 Honda CRX gets 40-41 mpg like clockwork, with 200k on the speedo. As far as I know, no late-model 'conventional' car gets this much, and real-world Prius mileage isn't much better.

I have noticed and wondered about this as well. I think size has a lot to do with it when comparing specific models. My friend's new Corolla appears remarkably similar in size to my 87 Camry. A new Camry would be much larger than mine. Also, it seems to me that engine power has gone up a lot in specific models, presumably increasing weight and encouraging us to accelerate faster, etc. For instance, a new Camry appears to be available with either a 2.4 liter 4 cyl. engine or a 3.5 liter V6 engine, whereas mine has a 2.0 liter engine, and when Toyota introduced the V-6 Camry I believe it had about a 2.5 liter displacement.

Just my thoughts -

The real reason U.S. automakers turned to power and speed is because that is what US consumers wanted!

Chevrolet has more models with an EPA estimated fuel efficiency of 30+ mpg hwy than any other automobile manufacturer. And the 2009 model full-size nine-passenger hybrid Tahoe "hulking" SUV with a 6.0 liter 332-horsepower V8 is EPA rated with the same city fuel efficiency as a standard 4-cylinder Toyota Camry (21 mpg).

You should be wary of several of the devices on the market. Before you decide to use a device to increase your fuel economy, you may want to do some research on the product’s effectiveness and potential dangers to your car. This will make sure you don’t cause a bigger problem than the one you’re trying to solve.
