Answer:
Toroidal coils as in ignition coils perform the same function as standard coils. The difference is that the magnetic fields are better focused and generally do not leak as much energy into the surrounding environment. Is there a difference in car performance? Very hard to say as generally stock ignitions these days (post 1990s) are excellent and do their job remarkably well.
