FI is because of the EPA, and has nothing to do with weight. It's a fuel-cheap way to make more power on demand, and would happen regardless of weight fluctuation of the vehicle. It's just an evolution like fuel injection, which is slowly giving way to DI. It's just a "better" way. It can now be integrated with minimal/no lag, and that was what BMW was "waiting" for.
Turbos only make sense. Keep the engine in vacuum and you get great economy and the EPA is happy. Floor it and the car GOES, and the enthusiast is happy.
What's not to like?

Now yes, safety structures DO have weight, but they are more than offset by smarter engineering and advanced materials--harken back to the 350 vs. 370 curb weights even though the 370Z is a LOT more rigid.

The 370z was the lone sports car which did that, and it was one of the reasons I bought it.
And yes, moar weight = less efficient. Safety measures add weight = car less efficient = fix with FI. Yes, the EPA required higher average mileage across manufacturers' model lines (hello, Aston Cygnet). But the cars would be more efficient if they weren't so heavy.
