The 2021 Nissan Titan XD is a unique domestic pickup featuring a muscular design and heavy-duty performance. This second-generation model is offered solely with a powerful 5.6L Endurance V8 with 400 horsepower and 413 lb-ft of torque, paired with a 9-speed automatic transmission. The Titan XD stands apart as it’s available exclusively with a 4WD drivetrain, offering impressive off-road capabilities. There are five available trims—S, SV, PRO-4X, SL, and Platinum Reserve—each offering a bevy of standard or optional features. Noteworthy elements include an 8" touchscreen infotainment system with Apple CarPlay and Android Auto, and Nissan's comprehensive Safety Shield 360 driver-assist suite. For 2021, small updates were made throughout the range, with the biggest being the discontinuation of the Diesel version.
