All editions of the 2012 Chrysler 300 come with standard power windows, locks and mirrors; LED daytime running lights; push-button start and keyless entry; a power driver seat; cloth upholstery; dual-zone climate control; satellite radio; a USB port; and an 8.4-inch LCD touchscreen display.
The upgraded version of that system, called UConnect Touch, is included with 300S, 300C, and SRT8 models, and adds hands-free texting capability, text-to-speech capability on incoming texts, voice-command navigation, Sirius Traffic information, and iPod controls.
The 300S adds sport leather front seats; shift paddles; piano black trim; and performance tires. The 300C gets a premium grade of leather upholstery; natural wood trim; navigation; power-adjustable pedals; and a heated steering wheel. SRT8s have carbon-fiber trim; heated and ventilated front seats; and a layer of instrumentation in its navigation system that displays performance stats like acceleration times and lateral grip.
In addition to the higher-performance engine, the SRT8 adds a host of heavy-duty extras under the hood, a performance suspension with adaptive damping, a performance braking system, 20-inch SRT-design wheels, fog lamps, auto-leveling HID headlamps, rain-sensitive wipers, heated-and-ventilated front seats, leather-and-suede upholstery, a heated steering wheel, heated/cooled cupholders, power-adjustable pedals, and more.
A 900-watt Harmon Kardon sound system is now an option on most models, and a "uConnect Web" option plugs in a 3G dongle into the car and turns it into a mobile WiFi hotspot.
