Selling compact trucks in the United States under the Datsun brand for the first time in the late 1960s, Nissan has shown a constant effort to broaden their presence in the work vehicle segment. Replacing the Hardbody small pickup truck in 1997, the Frontier provides ample flexibility with four-cylinder and six-cylinder powerplant options. Replacing the Nissan Frontier as the brand's flagship pickup truck was the Titan. The full-sized Nissan Titan is constructed to directly challenge American pickup trucks. In addition to a V-8 engine, the Nissan Titan has recently added an XD trim model with a diesel powerplant. Since 1983, Nissan has been building pickup trucks in the United States.
