Chrysler Group's Dodge brand plans to tweak the Nitro SUV line for 2011 with the addition of the Heat 4.0 Lifestyle Package.
The Nitro line was revised last year, and the models were given new names: Heat, Detonator and Shock.
Additionally, selected 2011 Nitro models feature upgraded interiors with new cloth and leather with premium-colored stitching, Jeep says. The Detonator and Shock models now feature Dodge's new racing-stripes trademark.
Chrysler made the announcement Tuesday on its Web site.
The Heat 4.0 Lifestyle Package includes a five-speed automatic transmission, Uconnect Phone and an upgraded eight-speaker sound system. A 260-hp, all-aluminum, 4.0-liter overhead-cam V-6 engine is standard, producing 265 pounds-feet of torque.
