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 powertrain combination delivers an EPA-estimated 27 mpg city and 38 mpg highway. The QR25DE is known for its smooth operation and decent fuel economy, though it’s not particularly powerful for the 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. Many engine components, suspension parts, and interior pieces are also compatible with 2016-2018 models, though some minor changes occurred during the mid-cycle refresh. Body panels and exterior trim generally interchange between 2013-2015, while 2016-2018 models received updated styling. The CVT transmission and 2.5L engine remained largely unchanged through 2018, making many powertrain components interchangeable. Always verify part numbers when sourcing components, as running changes can affect compatibility even within the same model year.

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 crankshaft position sensor around 100,000 miles and addressing minor oil leaks from valve cover gaskets. The engine’s biggest weakness is its pairing with Nissan’s problematic CVT transmission, which often fails before the engine shows significant wear. Overall, the 2.5L engine is more reliable than the transmission it’s connected to.
