The 2014 Nissan Altima comes standard with a 2.5-liter naturally aspirated four-cylinder engine (QR25DE) that produces 182 horsepower and 180 lb-ft of torque. This aluminum-block engine features dual overhead cams, variable valve timing on both intake and exhaust sides, and a drive-by-wire throttle system. The engine is paired with Nissan’s Xtronic CVT (Continuously Variable Transmission) as standard equipment. This powerplant provides adequate performance for daily driving while achieving EPA ratings of approximately 27 city/38 highway MPG. The QR25DE is known for its smooth operation and reasonable fuel economy, making it a popular choice in the midsize sedan segment.

The 2014 Nissan Altima shares most parts with the 2013-2015 model years, as these represent the early years of the fifth-generation Altima with minimal changes. Many engine components, suspension parts, and interior pieces are also compatible with 2016-2018 models, though some electrical connectors and trim pieces may differ. The 2.5L QR25DE engine components are largely interchangeable across the entire 2013-2018 generation. Body panels like doors, fenders, and hoods fit 2013-2015 models perfectly, while 2016-2018 models received minor styling updates that may affect fitment. Always verify part numbers when sourcing components, especially for electrical parts, as running changes occurred throughout the production run.

The 2.5L QR25DE engine in the 2014 Altima is generally reliable when properly maintained, with many examples reaching 200,000+ miles. The engine itself rarely experiences major internal failures, though it requires regular oil changes every 5,000 miles to prevent timing chain stretch and variable valve timing issues. Common maintenance items include replacing the air filter, spark plugs every 100,000 miles, and monitoring for minor oil leaks from valve cover gaskets around 100,000 miles. The engine’s biggest weakness is its pairing with the problematic CVT transmission, which often fails before the engine shows any significant wear. Overall, the 2.5L engine is more dependable than the transmission it’s connected to.
