Tech, safety, comfort, etc all adds weight, but I can’t help feeling that some manufacturers are maybe missing an opportunity for the “light” cars they could produce...

But that being said, sales numbers show that the lightweight sports car lovers are a tiny minority (just look at volumes of sales of the cars mentioned).
It’s a real pity because losing a few kg has big benefits... but most would rather argue about their extra 5hp.
