That’s better than the Honda Civic or Toyota Corolla. The 2012 Elantra breaks convention, and years of compact car complacency. This is not your ordinary compact ride. Elantra’s sophisticated 6-speed SHIFTRONIC automatic transmission uses new technology to improve durability and reduce weight. The result is greater fuel efficiency with smooth acceleration for the highway, while balancing power and comfort for in-town traffic.
