Savage geese on yt had put it perfectly when reviewing the Shelby. It is an economy car at its core. Same as challenger and Camaro. They need to be able to sell the car at 25 grand, as well as 100 grand.I've seen just today some discussion of dropping as much as 300 lbs from midsize cars by using more high-strength steels, but those were FWDs, so that does change the equation a bit. Nippon Steel has come up with a high strength steel that will reduce a car body weight by 30%, putting it on par with aluminum, and giving a superior product, but no idea on the cost.
Loose enough weight, and the price would be too much. Not to mention most buyers expect 200k+ miles out of these cars, and what cheap easy repairs
