The 2010 Nissan Altima comes standard with a 2.5-liter inline 4-cylinder engine (QR25DE) that produces 175 horsepower and 180 lb-ft of torque. This naturally aspirated engine features dual overhead cams, variable valve timing, and electronic throttle control. It’s paired with either a 6-speed manual transmission or Nissan’s Xtronic CVT (Continuously Variable Transmission). The engine is known for smooth operation and decent fuel economy, achieving approximately 23 mpg city and 32 mpg highway with the CVT. This powerplant provides adequate acceleration for daily driving while maintaining reasonable reliability when properly maintained with regular oil changes and scheduled services.

The 2010 Nissan Altima shares most parts with the 2007-2012 model years, as these represent the fourth generation Altima with minimal mid-cycle changes. Engine components, transmission parts, suspension pieces, and most body panels interchange directly across these years. Some electrical components and interior trim pieces may have minor variations, particularly between pre-2010 and 2010-2012 models due to a mild refresh. The 2.5L QR25DE engine remained largely unchanged throughout this generation, making engine internals, sensors, and accessories highly interchangeable. However, always verify part numbers when dealing with specific electronic modules, as software versions and connector configurations may differ between model years.

The 2.5L QR25DE engine in the 2010 Altima is generally reliable when properly maintained, though it has some known weak points. The engine itself typically lasts 200,000+ miles with regular oil changes every 5,000 miles using conventional oil or 7,500 miles with synthetic. Common issues include crankshaft position sensor failures around 80,000-100,000 miles and occasional oil consumption in higher-mileage examples. The timing chain system is robust and doesn’t require regular replacement like timing belts. However, the CVT transmission paired with this engine is less reliable and prone to premature failure. Overall, the engine rates above average for reliability in its class, but transmission concerns affect the vehicle’s long-term dependability.
