In 2008, the Sentra offered two four‑cylinder engines: a 2.0-liter base engine and a larger 2.5-liter option available on higher trims.
Engine options by trim
The 2008 Sentra lineup used two gasoline four-cylinder engines. Here are the typical specs by engine.
- 2.0-liter inline-4 (QR20DE) — roughly 140 horsepower and about 147 lb-ft of torque. This engine powered most base and mid-range trims.
- 2.5-liter inline-4 (QR25DE) — roughly 177 horsepower and around 172 lb-ft of torque. This larger engine was used in the higher-performance SE-R and SE-R Spec V models.
The two engines illustrate Nissan’s strategy for the 2008 Sentra: maintain economical operation in standard models while offering more power in sportier variants.
Why the distinction matters
Choosing between the two engines affects acceleration, overall performance, and how the car feels on the road. If you own or are considering a 2008 Sentra SE-R or Spec V, you’re looking at the 2.5L option; otherwise, the 2.0L is the common choice.
Summary
Summary: The 2008 Nissan Sentra offered two four-cylinder engines—2.0 liters (QR20DE) for standard trims and 2.5 liters (QR25DE) for higher trims like the SE-R and Spec V—providing about 140 hp versus 177 hp, respectively.
