For your information, Torsion Beam is more comfortable than wishbones in compact class saloons. Since Corolla has Gas Filled Shocks instead of Oil Filled ones, its comfort over uneven roads is much better than Civic.
Rahe bat Torsion Beam ki, Nissan Sunny has torsion beam as well and a friend of mine has driven a 1.6 Sunny at speeds above 200 in Saudia. Something that wasnt possible in a double wishbone'ed Civic there.
You need a sports car? Go buy one. These are simple family saloons, and in that domain, Corolla fares better.
