Kia Soul offers an agile, smooth and spirited ride. Its 1.6-liter, four-cylinder engine is mated to a five-speed manual transmission, which produces approximately 120 horsepower. For those looking for a little more power, a 2.0-liter four-cylinder engine is available with either the five-speed manual or a four-speed automatic transmission. The latter engine produces approximately 140 horsepower, and is available for Soul+, Soul! and Soul sport. Fuel economy for both engines is estimated at 30 or more miles per gallon.
