Here's why:
* Efficiency: Turbochargers improve fuel efficiency by using exhaust gases to spin a turbine that forces more air into the engine's cylinders, allowing for more complete combustion and better power output.
* Power: Turbocharging significantly increases horsepower and torque, especially at lower engine speeds, making diesel engines more responsive and powerful.
However, there might be a few Kia models with naturally aspirated diesel engines, especially in older models. If you're looking for a specific Kia diesel engine, it's best to check the model specifications or consult a Kia dealer for confirmation.
