Does the Kia Carnival offer a smooth and quiet cabin, especially during highway driving?

The Kia Carnival does offer heated and ventilated seats for both front and rear passengers in higher trims. The front seats have 3-level heating and ventilation, while the rear seats have 2-level heating and ventilation. These features help to keep the passengers comfortable in extreme temperatures.

The Kia Carnival is available with two engine options. The first is a 3.5-liter V6 engine that produces 290 horsepower and 262 lb-ft of torque. The second is a 2.2-liter four-cylinder diesel engine that generates 202 horsepower and 325 lb-ft of torque. Both engines are mated to an eight-speed automatic transmission and come standard with front-wheel drive. The V6 engine provides quick acceleration and smooth power delivery, while the diesel engine offers better fuel efficiency and more low-end torque for improved towing and hauling capabilities.
