Which advantage is associated with Nissan's direct injection technology?

Nissan's direct injection technology is designed to enhance the performance of the engine by delivering fuel directly into the combustion chamber at high pressure. This method allows for a more precise mixture of air and fuel, which leads to improved combustion efficiency. As a result, the engine can generate more power from the same amount of fuel, significantly enhancing fuel efficiency. The direct injection system reduces fuel consumption and emissions compared to traditional fuel delivery methods, which translates into better overall mileage and performance for Nissan trucks.

The other options do not pertain directly to the function or advantages of direct injection technology. For instance, increased cargo space relates more to the design and structure of the truck itself, while higher towing capacity is influenced by factors like engine power and chassis strength rather than fuel delivery methods. An enhanced audio system is unrelated to engine technology, focusing instead on entertainment and comfort features within the vehicle.
