The current Nissan Frontier uses a 3.8-liter V6 gasoline engine delivering about 310 horsepower and 281 lb-ft of torque.
The question spans model years. In the 2022–present Frontier, Nissan introduced a 3.8-liter V6 paired with a 9-speed automatic transmission, with 2WD and 4WD options. Older Frontiers (2005–2019) used a 4.0-liter V6 generating roughly 260–265 hp and around 281 lb-ft of torque, with transmission options that varied by trim. Diesel options have not been offered in the U.S. market for this model.
Engine options by generation
Below is a concise look at how the Frontier’s powertrain has evolved across its generations.
- Current generation (2022–present): 3.8-liter V6 gasoline engine; about 310 hp and 281 lb-ft; 9-speed automatic; 2WD and 4WD configurations; no diesel or hybrid option.
- Earlier generation (2005–2019): 4.0-liter V6 gasoline engine; roughly 260–265 hp and 281 lb-ft; transmissions varied by trim (manual and automatic offerings); 4x4 variants available.
The shift from a larger-displacement V6 to a more compact, higher-output 3.8L V6 mirrors Nissan’s push for modern performance and efficiency while keeping the Frontier's rugged capability intact.
