2020 Nissan Frontier

The 2020 Nissan Frontier represents the final year of the second generation, a model known for its simplicity and ruggedness. The 2020 Frontier came standard with a 3.8-liter V6 engine, producing 281 horsepower and 281 lb-ft of torque, paired with a 9-speed automatic transmission. While lauded for its updated powertrain in its final year before a redesign, the aging platform drew criticism for its outdated interior and less refined ride compared to newer mid-size truck competitors. Owners often appreciate the Frontier’s reliability and straightforward design, but dislike its fuel economy and lack of modern technology.
