Why are most hybrid vehicles so small and have such an ugly design?
I read an article on edmunds.com that was talking about how by 2015 all cars manufactured will have to meet the standards for MPG, and they are really high. It goes by the footage of the car's area in size. The bigger the car, the lower the standard for MPG. So, SUV and van designs have to include better engines that consume less gasoline, but they won't be completely extinct or anything. The real issue for that is high-powered sports cars, like the Porsche, fall into the same class as the honda civic, and the Porsche engine is notorious for eating up gas. They will have to design a Porsche engine that gets like 35 to 40 mpg. That's more of a challenge that making an SUV engine get better gas mileage. But there are talks of excluding smaller companies that make a limited amount of cars, like Porsche and Lambo and Ferrari from those standards, so there may be a future for the sports car yet.
ETA: The exterior design of the hybrids doesn't bother me. I think they are creative and cute.
