Maybe they need to get some of that magic Hyundai high-strength pixie-dust steel. Either that, or just take some structure out of it.
while i know you are being factitious, they should use some high strength steel, or at least, more of it...of course, that would likely make this $50k Camaro more like $55k, which really isn't the direction the car needs to go...there is no reason why this car needs to weigh 400 pounds more than the Mustang...it should be about the same weight...and there is no reason why it can't have a better interior...the interior on the Cruze and Regal is far better, and those cars cost $15-20k less.
