The 2011 Infiniti G25 is equipped with a 2.5-liter VQ25HR naturally aspirated V6 engine producing 218 horsepower and 187 lb-ft of torque. This aluminum DOHC engine features variable valve timing on both intake and exhaust camshafts, electronic throttle control, and a 10.6:1 compression ratio. The VQ25HR was specifically designed as a smaller displacement variant of Nissan’s acclaimed VQ engine family, offering improved fuel economy while maintaining smooth power delivery. It’s paired with either a 7-speed automatic transmission or CVT depending on the trim level and drive configuration.

The 2011 Infiniti G25 shares most parts with the 2010-2013 G25 models, as this was the complete production run for this specific model. Many engine components are compatible with 2007-2012 Nissan Altima 2.5L models that used the same VQ25HR engine. Body panels, interior trim, and some suspension components interchange with 2007-2013 G35 and G37 sedans, though engine-specific parts like intake manifolds and exhaust systems are unique to the G25. Transmission parts vary significantly between manual, automatic, and CVT variants, so exact transmission type matching is crucial for compatibility.

The VQ25HR 2.5L V6 in the G25 is generally reliable but has some notable weak points. The timing chain tensioner system is the primary concern, requiring monitoring for rattling noises especially on cold starts. Regular oil changes every 5,000 miles with quality synthetic oil help prevent premature timing chain wear. The engine responds well to proper maintenance and can easily exceed 150,000 miles when cared for properly. Avoid extended oil change intervals and address any unusual noises promptly to prevent costly timing chain damage.
