Ask HN: Why don't companies make light weight performance cars anymore?

Hello HN,

I love small, light weight cars and I know I am not alone in this. What surprises me is the trend in the industry towards making heavier and larger cars with too much technology. Even porsche 911 gt3, the pinnacle of my ideal car (sub 3000 lbs, 400-500 hp, stick shift, mid or rear engine) is getting beefier and beefier.

Is there any hope that one of the existing manufacturers would make a carbon monocque (tub), carbon wheels, carbon brakes, naturally aspirated engine with 500hp, no tech car with a stick shift and rear-wheel power delivery? <- run on sentence :) But I am so surprised that nobody is tapping this market, it is an easy 100-300k sale depending on materials, design and performance.

What gives?
