Elantra Touring is called i30cw everywhere else in the world(other than US). It's based on i30 designed in Europe, which is quite bit different from Elantra. It has longer wheelbase(more passager room), firm suspension, and provides better control/road feedback and more fun to drive. However, the ride is a bit rough and noisy, comparing to Elantra. So it's tradeoff.
Not sure why Hyundai USA picked its name after Elantra though it's a very different car.
