Drivetrain

The typical sedan has a larger engine than the Kia Rio. Keep in mind that smaller engines are often cheaper to fix, but smaller engines can be stressed more. The Kia Rio could learn a lesson or two from the typical sedan when it comes to pickup. Torque is the force that lets you accelerate quickly, and in this respect, the typical sedan is tremendously more powerful than the Kia Rio.
