I don't think I'm confusing anything honestly. The two go hand in hand. It's the principle that if your car and my car were to get into a fight, who would win? I'm trying to come up with a good example of a light, cheap feeling SUV but I doubt we'll get very far on that point. Fact is, people like the feel of a heavy beast of a machine...people who don't enjoy turning.

People buy SUV's because they think it's safer. They like the heavy feel of the thing.

As long as steel continues to be more affordable to use in car manufacturing compared to aluminum and carbon fiber, and as long as people want more features and comfort options in their cars, they're not going to get lighter anytime soon. Plus, there's the safety factor. Most cars nowadays have at least 6 airbags, and that alone adds a lot of weight, but if it helps get or keep a 4 or 5-star crash ranking from NHTSA (which, along with features and MPGs, is a selling point for any new car), then adding those extra pounds is a no-brainer for automakers.

Shedding weight also increases MPG though...

True, but automakers don't consider that because:

a. It's too costly to build frames with lighter materials in mass-production. An automaker may use aluminum or CF in a single model (often a halo model and 99% of the time a sports car), but to try and extend that to the rest of the lineup will make them increase the prices of their vehicles to compensate for their manufacture expenses, and people nowadays don't want to spend more than needed, especially when the gross of the consumers buy cars as an appliance.

b. If they take the route of eliminating features consumers will shift their focus on competitors who offer features than X brand doesn't.

So automakers turn to other MPG-improving means like diesel engines and gas/electrical hybrid systems, among other things. Reducing weight is pretty much the last thing on the list because, like someone posted before, people tend to associate "light" with "small", "cheap", "unsafe" and "not enough features"....once automakers attempt to change that kind of mindset on the consumers we may start seeing lighter cars...

Its also important to note, that this "big=safe" mindset is pretty much exclusive to the US. Europe definitely does not think like that, as there are plenty of small, premium cars that are very popular. But they also have very high gas prices.

A few years ago with the fuel spike in the US, you definitely started to hear about the US makes wanting to produce small, premium cars. But that went away after the price of gas came back down.

My prediction...the US will be forced to change their mindset once gas goes back up to $5-7/gal (and it definitely will). This will also push the development of weight saving technologies.

The US automotive buying habits will never change automatically. It will be forced to change. Higher gas prices will get us back to smaller cars, and it will also make the smaller cars even lighter to get better MPG. Win-Win with expensive oil.

The correct way of saying that would have been to compare a Hyundai Accent hatch to a VW Golf. If you know absolutely nothing about cars you would perceive the VW to have a significantly higher quality based on the much more solid feel of the vehicle (weight) and the stability it has (weight) and the very nice (by comparison) interior and its panels which have a nice sound if you tap them (weight) and additional sound deadening (weight) ect ect ect...

Accent 3 door weight 2457
Golf 3 door weight 2968

500lbs of quality feel.

Poster, I mean poster. What have I done?
