The 2007 Infiniti QX56 is equipped with a 5.6-liter VK56DE V8 engine that produces 320 horsepower and 393 lb-ft of torque. This naturally aspirated DOHC engine features aluminum construction with cast iron cylinder liners and variable valve timing on both intake and exhaust camshafts. The engine is paired with a 5-speed automatic transmission and available in both rear-wheel and all-wheel drive configurations. This powerplant provides strong towing capacity of up to 9,000 pounds when properly equipped, making it suitable for heavy-duty applications while delivering reasonable fuel economy for its class.

The 2007 Infiniti QX56 shares most parts with the 2004-2010 first-generation QX56 models, as they all use the same platform and 5.6L VK56DE engine. Many engine components, suspension parts, and interior pieces are directly interchangeable across these years. Additionally, since the QX56 shares its platform with the Nissan Titan and Armada, many mechanical components like brake parts, suspension components, and drivetrain pieces are compatible with 2004-2015 Titans and 2004-2015 Armadas. However, some electrical components and body panels may have minor variations between model years, so verification is recommended for specific applications.

The 5.6L VK56DE engine in the 2007 QX56 is generally reliable when properly maintained, but has some known weak points. The timing chain tensioner issue is the most serious concern and should be monitored closely, especially after 80,000 miles. Regular oil changes with quality oil are critical, as this engine is sensitive to oil quality and change intervals. The engine responds well to premium fuel and benefits from regular maintenance of the variable valve timing system. When the timing chain components are properly maintained or updated, these engines can easily exceed 200,000 miles with proper care and regular maintenance schedules.
