For 2021, the Nissan Frontier doesn't get significant changes. One of the longest-running pickup truck lines, this mid-size truck continues to offer one of the most powerful engines and value in its class. The Nissan Frontier has three trim levels. The first trim is the S. The S has a keyless ignition for easy starting. It also has remote keyless access and push-button ignition. You get a seven-inch infotainment screen supporting Bluetooth technology. The audio controls are mounted to the steering wheel for easy reach. With the SV, the second trim up, you'll get more stylish 16-inch alloy wheels. The SV has a body-colored bumper on the front end and a chrome bumper in the back, along with the new grille. You can opt for one of several options packages on the SV trim: Value Truck (including heated front seats, fog lights, rear parking sensors), Special Edition (including 18-inch alloy wheels, a trip computer, and unique exterior treatments), and Midnight Edition (includes black-painted exterior trim and 18-inch black-painted wheels). Topping the list is the off-roading-focused PRO-4X, with standard four-wheel drive, an Electronic locking rear differential, Bilstein shock absorbers, underbody skid plates, and all-terrain tires.
