The Altima is powered primarily by four-cylinder engines in its latest generations, with a turbocharged option available in more recent years. Today’s models offer a 2.5-liter inline-four or a 2.0-liter turbocharged inline-four (VC-Turbo); older generations also offered a 3.5-liter V6. The exact motor depends on the model year and trim.
Current engine options
As of the latest generations, the Altima provides two primary four-cylinder powertrains, with the turbo option aimed at more spirited driving.
- 2.5-liter naturally aspirated inline-four
- 2.0-liter turbocharged inline-four (VC-Turbo) with variable compression ratio
In daily use, most buyers will encounter the 2.5-liter base engine, while the 2.0-liter VC-Turbo is chosen for enhanced performance and efficiency characteristics. The engines are typically paired with a continuously variable transmission (CVT), contributing to efficiency and smooth operation.
Historical engines and evolution
The Altima’s engine lineup has shifted over time, reflecting Nissan’s efficiency goals and market demand. Earlier generations of the Altima included a larger V6 option, and four-cylinder options have proliferated since then.
- 3.5-liter V6 (VQ35DE) offered in mid-2000s to early-2010s models
- 2.5-liter four-cylinder (various iterations, including QR25DE and MR-series designs) used across many years
- 2.0-liter turbocharged four-cylinder (VC-Turbo) introduced for the 2019 model year and continued in newer trims
This evolution mirrors a broader industry shift toward smaller, turbocharged or highly efficient four-cylinders, while the V6 option was phased out in the later generations of the Altima.
What this means for buyers and owners
When shopping for an Altima, know that the motor under the hood will largely determine performance, fuel economy, and maintenance needs. The current lineup emphasizes four-cylinder efficiency, with the optional turbocharged variant offering more power at the expense of slightly higher complexity and potential maintenance costs compared to the base engine. Always verify the model year and trim to confirm which engine is installed, and review maintenance history for any turbocharged variants.
Summary
In short, the Nissan Altima’s modern powertrains are built around inline-four engines: a 2.5-liter naturally aspirated unit and a 2.0-liter VC-Turbo turbocharged unit. A prior generation relied on a 3.5-liter V6, but that option has largely been retired from current models. Engine choice varies by model year and trim, shaping performance, efficiency, and ownership considerations.
