What is the noise insulation level in the Kia Carnival, especially when driving at high speeds?

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.
