The 2023 Nissan Altima uses two four-cylinder engines: a 2.5-liter naturally aspirated inline-four and an optional 2.0-liter VC-Turbo inline-four, both paired with Nissan’s Xtronic CVT. This means the Altima does not offer a V6 in 2023 and emphasizes a balance of efficiency and accessible performance.
In more detail, the base engine is designed for smooth, efficient daily driving, while the VC-Turbo option adds turbocharged power through a variable compression ratio system. Both engines are front-wheel drive as standard, with all-wheel-drive available on select trims and all engines mated to a continuously variable transmission for seamless acceleration.
Engine Options
The Altima’s engine lineup centers on two four-cylinder choices. The following options are available to buyers, varying by trim and configuration.
- 2.5-liter inline-4 (naturally aspirated): approximately 188 horsepower and 180 lb-ft of torque; direct injection; paired with a continuously variable transmission (CVT).
- 2.0-liter VC-Turbo inline-4 (turbocharged, variable compression): approximately 248 horsepower and 273 lb-ft of torque; turbocharged with a variable compression ratio for broad torque delivery; also paired with Nissan’s Xtronic CVT; available on higher trims.
These two engines provide a choice between efficient, everyday driving and higher-performance capability without stepping up to a V6.
What is VC-Turbo technology?
VC-Turbo stands for Variable Compression Turbo. This engine uses a mechanism to adjust the compression ratio on the fly, aiming to optimize efficiency at lower loads and boost performance under acceleration. Coupled with turbocharging, the 2.0-liter VC-Turbo delivers strong low- to mid-range torque and responsive acceleration while maintaining competitive fuel economy for its class. In the Altima, this engine is paired with Nissan’s CVT to maintain smooth, continuous power delivery.
Performance and driving characteristics
The 2.5-liter engine is tuned for quiet, efficient operation and steady highway cruising, making it the default choice for most buyers who prioritize fuel economy and comfort. The VC-Turbo, by contrast, targets buyers who want stronger pull and quicker acceleration, especially from lower speeds, without moving up to a larger V6. Both options share the CVT transmission, ensuring a smooth driving experience, though the feel of acceleration will differ between the two powertrains.
Summary
The 2023 Nissan Altima offers two four-cylinder engines: a 2.5-liter naturally aspirated inline-four and an optional 2.0-liter VC-Turbo inline-four. Both are paired with a CVT and front-wheel drive (with AWD available on some trims). The 2.5L prioritizes efficiency and everyday usability, while the VC-Turbo adds turbocharged power through variable compression technology for sharper performance when needed.
