This is mostly because hybrids have brought the car averages up enough that they can now sell larger "cars" without blowing their targets.

And crossovers are cars. A Subaru Forester used to be called a station wagon, now it's a crossover.

Most of them also have a similar power to weight ratio to a 1980s 5.0 liter V8 Mustang, so I still don't see the argument that people stopped caring about performance.
