Correct. They have not.
There aren't any serious sports cars that are FWD that I know of - they are either RWD or AWD.
FWD = has lots of weight right over the wheels and most often 1 (as most have open diffs) and sometimes 2 wheels that have perform 2 functions concurrently of turning & braking or turning and accelerating. In an open diff FWD you simply run out of tire almost instantly, and with a limited slip FWD car you run out a bit later.
RWD car with limited slip distributes the acceleration and turning between 4 tires and has better front-rear balance (especially with a transaxle).
True it has a tunnel to deal with running through the passenger cabin.
