2001 Nissan Frontier

The 2001 Nissan Frontier is a compact pickup truck known for its reliability and off-road capability. It offers several engine and transmission options. The most common engine is the 3.3L VG33E V6, producing around 170 horsepower and 200 lb-ft of torque. Other engine options include a 2.4L KA24DE inline-4, which provides around 143 horsepower and 154 lb-ft of torque. Transmission choices typically consist of a 5-speed manual or a 4-speed automatic.
