The Frontier is offered in four trim levels: the base XE, the well equipped SE, the luxurious LE and the PRO-4X off-road model. Available engines include a 152-hp 2.5-liter four-cylinder, mated to either a five-speed manual or five-speed automatic transmission, and a 261-hp 4.0-liter V6, paired with either a six-speed manual or five-speed automatic transmission. Standard safety features include four-wheel anti-lock disc brakes, dual front, front side-impact and overhead curtain airbags, active anti-whiplash front head restraints and a tire pressure monitor. New for 2010, SE V6, LE and PRO-4X trim levels are outfitted with Nissan?s Vehicle Dynamic Control (VDC) electronic stability control system, including integrated traction control. The Nissan Frontier carries over with minimal changes for 2010. Every Frontier is now equipped with side and overhead curtain airbags, while Vehicle Dynamic Control (VDC) is standard on SE V6, LE and PRO-4X trims. Additionally, the SE Value Truck Package now includes a Class IV Tow Hitch Receiver.
