The base version of the Kia Sorento, a midsize SUV, has a four-cylinder engine, but those in the market for a little more gusto will opt for the 2.0L turbo that can tow up to 3500 pounds (1588 kg). If you need to tow up to 5000 pounds (2268 kg), the 290-horsepower, 3.3L V6 is the best choice. The Sorento features a Dynamax all-wheel drivetrain, but the base versions are equipped with front-wheel drive.
