I'm going to finally chime in and say that at least in my eyes there is no such thing as a FWD sports car.
There are many that come close but they'll never quite make it. I can most definitely appreciate their performance capability around corners but they're just not sports cars.
I do consider pony cars to be sports cars (despite not being particularly good ones) but they are still sports cars. FWD is a compromise for interior space and cost efficiency almost all of the time and a sports car should do what it does as well as it can.
Unfortunately, you'll have to define in concrete terms why they
aren't.
If, like Keef, you personally think they aren't because, in your personal opinion, they aren't, regardless of performance, that's it. I'll disagree with you, but it's your opinion.
I'd like to point out it's just like saying all Pizza
must be round. Just because most Pizzas are round doesn't mean that they can't be square (and yes, there are square traditional Pizzas).
But if you invent reasons that aren't reasons, there are lots of ways to poke holes in your argument.
You state that you consider pony cars to be sports cars, but pony cars are a compromise for interior space (high roofline, 2+2 seating, front engine to give you a useable trunk) and cost-efficiency (manufacturing synergy, since they're built on the same platform as sedans by the same manufacturer). If you argue via these functions, there are FWD sports cars that are far less compromised and far more deserving of the title "sports car" than "pony cars" are.
And defying physics is something front-drivers can do quite well... thank you.
(as well as training future F1 and Rally champions...)
