The QR25 is one of the most powerful 4-cylinder engines in its class. High torque helps the vehicle accelerate through busy intersections and provides more available power (especially when accelerating and passing) while reducing engine stress.

Go for it. A 250 horsepower V6 engine from the award-winning VQ series provides outstanding response. Double overhead cam (DOHC) design provides direct actuation of intake and exhaust valves for enhanced performance and efficiency.

The Nissan 3.5-liter VQ V6 engine has been named to the annual Ward's 10 Best Engines list for the 11th straight year by Ward's Communications, Inc. Click "learn more" for more details.

4-valve design provides more efficient flow of air and fuel (intake and exhaust gases), which enhances power output without reducing fuel economy.

Unlike timing belts, timing chains do not require scheduled maintenance inspections or replacement for the service life of the engine. Timing chains provide more precise and reliable actuation of camshafts.

Aluminum-alloy construction reduces engine weight for improved performance and fuel economy. Use of lightweight components reduces energy losses during operation, allowing engine speed to rise faster for improved response with less vibration.

Microfinishing is a separate manufacturing process that puts an ultra-smooth finish on rotating surfaces, enabling the shafts to turn with the least possible resistance reducing heat and vibration.

By varying the intake paths, the airflow is "tuned" to match the needs of the engine, enhancing its power output and driveability.

Continuous Variable Valve Timing Control (CVTC) delivers great on-road acceleration, overtaking performance and top speed, together with excellent fuel economy.

Precise quantities of fuel are injected at exactly the right moment in relation to valve timing and piston position, enhancing overall driveability and, especially, hot and cold starting capability.

Nissan Induction Control System (NICS), boosts torque at all speeds by the use of a variable induction valve.
