Well, we truly live in the golden age of performance cars. I mean, Honda Accords with 0-60 times in the 6 second range? Family sedans with 300+ NET horsepower? That's awesome. On the other hand, they are also getting a lot heavier as we add more accessories like GPS, climate control, audio/visual systems, etc. I agree that some of this weight is for safety/structural improvements, but the new Mustang and Camaro weigh close to two tons! That's a heavy weight.
If current trends continue, cars will have 1000 HP ethanol burning engines and weigh about as much as an M1 tank, yet manage to get 50 mpg. Luckily, it'll only cost you 500 grand.
