A TRD Sport version with Bilstein suspension and stabilizer bars is added this year to certain versions of the Tundra. 20-inch rims, a unique grille, an air intake in the hood and TRD logos here and there also help differentiate this more aggressive version. Two V8 engines – a 4.6L and a 5.7L developing 310 and 381 horsepower respectively – are available. The maximum towing capacity is 4535 kilograms (10,000 pounds).
