What type of engine technology is employed in the 2025 QX55 to enhance power output?

The 2025 QX55 utilizes turbocharged engine technology with an air-cooled intercooler to enhance power output. Turbocharging is a method that increases the efficiency and power of the engine by forcing more air into the combustion chamber, allowing for a more complete burn of fuel. This leads to a significant boost in horsepower without a corresponding increase in engine size.

The air-cooled intercooler plays a crucial role in this process by reducing the temperature of the air entering the engine, which helps to maximize intake density. Cooler air is denser, meaning it contains more oxygen molecules, which results in improved combustion efficiency and increased power output. This combination of turbocharging and the air-cooled intercooler is a well-established strategy in modern engine design to achieve higher performance while maintaining fuel efficiency.

In contrast, the other options represent different approaches to engine technology that do not specifically describe the setup used in the 2025 QX55. Supercharged engines rely on a different mechanism for boosting power, while twin-turbo engines employ two turbochargers for performance enhancements. Hybrid systems integrate an electric motor with a traditional engine, focusing more on fuel efficiency and emissions than sheer power output.
