2002 Toyota Tundra

The 2002 Toyota Tundra was a full-size pickup truck available in various configurations, offering a blend of reliability and capability. Engine options included a 3.4L V6 producing approximately 190 horsepower and 220 lb-ft of torque, and a 4.7L V8 generating around 245 horsepower and 315 lb-ft of torque. The V6 was typically paired with a 5-speed manual or 4-speed automatic transmission, while the V8 came standard with a 4-speed automatic. Owners often praised the Tundra for its longevity, build quality, and smooth ride, while some criticisms included fuel economy and the relatively dated interior.
