2021 Nissan Frontier

The 2021 Nissan Frontier represents the last model year of the second-generation Frontier before a major redesign. All 2021 Frontiers came standard with a 3.8-liter V6 engine producing 310 horsepower and 281 lb-ft of torque, paired with a 9-speed automatic transmission. Owners generally liked the improved power and updated infotainment system compared to previous years of the second generation, but disliked the carry-over interior design and dated overall feel of the truck.
