The 2015 Nissan Frontier is a mid-sized truck that comes in two body styles: the King Cab and the Crew Cab. The range runs from the basic no-frills trim S, to the well-equipped SL. Engine options include a 2.5L 4-cylinder that pushes out 152 horsepower, or a 4.0L V6 offering 261 horsepower. Both engines have a standard five-speed automatic transmission, with a six-speed manual optional on the V6. The Frontier is available in a RWD configuration, with optional 4WD. All models feature a range of safety features including front-seat side airbags, full-length side curtain-type airbags, and stability control. Inside, the Frontier is equipped with an updated NissanConnect infotainment system with a 5.8" touch-screen display, Voice Recognition, hands-free text messaging assistant, and smartphone integration.
