2021 Ford F-150

The 2021 Ford F-150 marked a significant redesign for the popular pickup truck. It offered a range of engine options, including the 3.3L Ti-VCT V6 (290 hp, 265 lb-ft of torque), the 2.7L EcoBoost V6 (325 hp, 400 lb-ft of torque), the 3.5L EcoBoost V6 (400 hp, 500 lb-ft of torque), the 5.0L Ti-VCT V8 (400 hp, 410 lb-ft of torque), and the 3.5L PowerBoost Full Hybrid V6 (430 hp, 570 lb-ft of torque).
