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.
