I have always wondered why cars weigh so much. Then, recently, I read an article about how cars in the US have been getting heavier and heavier in the past 10 years. Consumers want a quiet, smooth ride; they equate this with quality. The cheapest way for designers to satisfy this is with big wheels and heavy bodies. As a result, 30mpg is considered good gas mileage these days.
Motorcycles have been getting lighter and lighter, as more motorcycle buyers are looking for sport performance. Maybe with the high gas prices, we will start seeing lighter cars based on the same technology.
I recently got a dent in the hood of my car, and I looked on the internet to find a replacement. The only hood I could find was a carbon fiber "performance" hood that cost over 500 dollars (ha), and claimed to be 40 lbs lighter than the stock hood. FORTY POUNDS? Why the heck do cars weigh so much?
