The 2015 Dodge Charger is offered in SE, SXT, R/T, R/T Road & Track, SRT 392 and SRT Hellcat trims. Charger SE and SXT models come with a 292-horsepower, 3.6L Pentastar V6, which the EPA rates at 23 mpg combined fuel economy. Both models come standard with rear-wheel drive but can be fitted with all-wheel drive. The R/T models channel Dodge's muscle-car past, stepping up to a 5.7L Hemi V8 with 370 horsepower and 395 pound-feet of torque. The engine utilizes variable cam timing as well as a four-cylinder mode for fuel saving when the extra power isn't needed. R/T cars also feature several performance upgrades to the suspension, exhaust, brakes, and seats. Top of the Charger heap are the SRT models: The SRT 392 is powered by a 6.4L Hemi V8 and delivers 485 horsepower and 475 pound-feet of torque; meanwhile, the SRT Hellcat features a supercharged 6.2L Hemi V8 good for 707 horsepower and 650 pound-feet. All Chargers make use of a standard TorqueFlite 8-speed automatic transmission. The Charger SE comes well equipped with 17-inch wheels, keyless entry and push-button start, a power driver's seat, air conditioning, other power accessories, and a Uconnect 5.0-inch touch screen. SXT models add 18-inch wheels, cloth sport seats with heated front seats, 4-way lumbar adjustability for the driver, dual-zone automatic climate control, auto-dimming rearview mirror, a HomeLink universal garage door opener, one year of SiriusXM radio, a voice-command Uconnect interface with 8.4-inch touch screen and Bluetooth connectivity, and a 276-watt Alpine 6-speaker premium audio system. In addition to the Hemi V8 and performance upgrades, the R/T provides 20-inch wheels, rev matching from a beefier TorqueFlite transmission, plus paddle shifters and Sport Mode. Also included are Alcantara suede and Nappa leather sport seats. The R/T Road & Track includes HID projector headlights and auto-dimming driver's side exterior mirror, ventilated front seats and heated rear seats, a heated steering wheel, power adjustable pedals and steering column and upgraded LED interior lighting. The SRT 392 is equipped much like the R/T Road & Track, though you'll also find a functional hood scoop and oil cooler, front and rear climate control outlets, unique interior appointments, a rear back-up camera, and adaptive damping, which adjusts firmness and allows Auto, Sport and Track modes. Finally the Hellcat brings performance-tuned steering, aluminum interior accents, and, of course, 707 horsepower. Notable options across the model range include the Driver Confidence Group, with a rear back-up camera, power heated foldaway mirrors, ParkSense parking assist and blind-spot detection. Navigation is available on SXT and both R/T models, while a 19-speaker Harman/Kardon 900-watt premium audio system is available on the two SRT models.
