Summer is rapidly approaching - traditionally a time when most people will use their cars for the annual family vacation. This summer, however, recent spikes in gasoline prices have many people thinking about canceling their plans and keeping the car in the garage. Hyundai Auto Canada offers much-needed relief for those planning to hit the open road by offering Canada's most fuel-efficient full-size sedan - the 2006 Hyundai Sonata. The Sonata's outstanding fuel economy has been recognized by Natural Resources Canada with its annual EnerGuide Award which proclaimed the 2006 Sonata GL the most fuel-efficient full-size sedan on the Canadian market.
