The very first Toyota Corollas hit the U.S. in 1968. Now in its ninth generation, the Corolla is a much bigger and more sophisticated car than it was originally. A subcompact until 1987, the car grew and is currently designated a compact. The current Corolla, which debuted in 2008, is the largest that Toyota has ever produced. The new Corolla comes with two peppy, efficient engines making the car one of the most popular small cars on the road. The Toyota Corolla comes with a five-year/60,000-mile powertrain warranty and gets an estimated 30-35 mpg on the highway.
