I think the thing that bothers me most is the idea of engineering right on the edge leaving no room for a safety factor. Extra thin wall castings, powder pressed con rods, plastic engine components etc. Overheat it once and you can kiss it all goodbye, turn it 100 rpm beyond redline and it all unravels etc. A good example is the 9" Ford axle, way overbuilt for the application but thank God they did. I like to have components a little heavier than required to account for the inevitable overload that will occur. Personally I could live with a car being a few pounds heavier if it was built to last and take some punishment. I think this is why trucks have become so popular, everyone is tired of buying disposable vehicles that can't take a 5 MPH hit in a parking lot without the steering wheel exploding in your face and the $1000 foam bumpers coming apart like a stuffed toy. I will rejoice in the day when I can actually buy a car that has chromed steel bumpers again. A non aerodynamic fin or two or stylish tailight wouldn't hurt either, really is this what we have to look forward to-jellybeans! You know my buddy has a 2002 Chevy ZR2 truck and it gets between 14-18 MPG with the 4.3, my 69 Mustang 351W tuned properly with the 3.0 axle got 16-18 even with the 290 duration cam and autolite 4 barrel. This is progress?
