The truck was available with front disc brakes and a Ford-built 2.3-liter engine option, which was the same engine used in the Ford Pinto and Mustang II. The key feature distinguishing the Courier from Mazda's B series was the single headlights, although with park and indicator lights were placed inset starting in 1978. 1977 models retained the turn signal lights in the bumper. In 1979, the base model engine was increased in size to 2.0-liters. The optional Ford 2.3-liter engine was produced in Brazil.
