Automobile Fuel Efficiency Or Lack Thereof

It's no secret the automotive industry isn't known for its innovation. While I highlight the American auto manufacturers as being generally unresponsive and delivering terrible products over the last half century, there's plenty of finger pointing when it comes to energy efficiency innovation. Getting significant gains out of the standard four stroke internal combustion engine is a slow and arduous process. Even if auto makers were able to achieve theoretical efficiencies, and they never will, we aren't looking at engines capable of hundreds of miles per gallon in a family sedan. In fact, we probably aren't looking at more than 40-50mpg in a gasoline powered family sedan. But, GM has spent more money on research & development since the 1970s than it took to develop whole new ranges of technology and put a man on the moon in the 1960s. Yet, for this we get a 2007 subcompact, the Aveo, which appears to get worse gas mileage than a 1975 or 1985 Chevette. Below is a headline news story from 1975 showing what appears to be the combined EPA mileage for a 1975 Chevette being 33mpg. Below that is a 1985 (The oldest model year I could find) Chevette with statistics pulled from a U.S. government page showing combined mileage of 31mpg with a manual transmission. And, below that is the 2007 Chevy Aveo subcompact with mileage numbers worse than a 30 year old GM car.

Is this what a shareholder of GM gets for its research dollars? A smaller car with less efficiency than a thirty year old car. Imagine if IBM or HP delivered a computer with less capability than thirty years ago. Now, I realize the comparison is not fair. But, what is fair is that GM and other auto makers have not really made any significant innovations as it pertains to environmental or fuel efficiency issues. They would tell me that it is because the market hasn't demanded it. I would tell them that it is their responsibility to create new markets. To tap into latent or unknown demand. To create demand around a relevant marketing message. So, did people not care about the environment for the last thirty years? Oh, that's right. Those people were radical liberals. An image reinforced by the automobile industry and its politician buddies.

So, does anyone have a 1975 Chevette? I'm concerned about the environment and the impact of high fuel prices on my wallet. I'd like to buy one. It's the best gas mileage of any car in the GM global portfolio of products. And, that is pathetic.
