If you want to be pedantic you’re going to need a new definition for sports car. Every single one of these is going to be a fat pig, with dead steering, and shitty sound. They’ll be fast and soulless. The shape doesn’t matter. If you want the classic definition of sports car, you basically have the Miata, brz, and a few supercars.
If you take a more open definition based on cars with performance you can track, then yes the mach e is as much a sports car as an M5, ct5v, mustang, etc. A 4000 lbs rx7 with a small rotary is as far from an actual sports car as you can get.
