With its bold styling and aggressive stance, Dodge Nitro is unlike any other midsize SUV in the marketplace. For 2010, Dodge offers two models: Nitro SE and SXT. New for 2010 is interactive Decel Fuel Shut Off (iDFSO). iDFSO turns off fuel during vehicle deceleration, which improves fuel economy. This feature, standard on 3.7- and 4.0-liter engines, improves fuel economy without any noticeable changes in engine performance. In addition, the new Fuel-saver indicator displays when the vehicle is driven in a fuel-efficient manner, providing drivers with continuous fuel-consumption feedback. The standard 3.7-liter V-6 engine on the 2010 Dodge Nitro SE and SXT models produce 210 horsepower and 235 lb.-ft. of torque. The 4.0-liter V-6 engine is optional on Dodge Nitro SXT. The engine delivers 260 hp and 265 lb.-ft. of torque. The 2010 Dodge Nitro features a coil-spring independent front suspension and a five-link, coil-spring rear suspension. The independent front suspension gives the driver an optimum combination of ride, handling and steering, which provides a greater sense of control and precision. The solid five-link rear suspension, including upper and lower trailing links and track bar, provides higher lateral stiffness for vehicle responsiveness and outstanding handling. A performance suspension is optional on Dodge Nitro SXT. This suspension emphasizes responsive, fun-to-drive handling accompanied by a firm ride. Dodge Nitro features a part-time four-wheel-drive system. Two-wheel- and four-wheel-drive lock modes are electronically controlled by a switch in the center console, which may be selected at any time with the part-time four-wheel drive system.
