<{POST_SNAPBACK}><!--quotec-->it stuns me how heavy these cars are - the new mustang, a full 1000lbs more than the early ones, is LIGHTER than the camaro and challenger? - that is truly sad - we used to think of 3800lbs as extremely heavy - that was what the big body dodges used to weigh - the smaller cars were a few hundred pounds less
what happened to those cool space age materials that were supposed to make cars lighter?<!--QuoteEnd--><!--QuoteEEnd-->
Yeah, it's amazing how heavy cars have become. A big part of it is the safety regulations - modern cars are infinitely more crash-worthy than the older light-weights. Think of how many air bags are in a modern car. Chassis's are also dramtaically stiffer than in years past, and this adds lots of weight. And of course we can't forget all the modern luxury items that used to be only available in more upscale cars - things like power windows, seats, mirrors, high-end sterios, nav systems, extra sound-deadening, automatic transmissions in something like 95% of all new cars, etc. Imagine the kind of mileage and performance that could be had with a modern engine stuffed into one of the old light-weight cars.
As far as the light-weight exotic materials, the big problem is cost. I've heard the epoxy used to protect the Corvette ZR1's carbon fiber roof from UV costs something like $2000/gallon. Ouch!
