Dodge revived a name from the past for a sedan companion to its Magnum wagon, which had debuted as a 2005 model. At the same time, for 2006, the company added high-performance versions of both cars. Both models shared their underskin design with the Chrysler 300 sedan, but Charger was available only with rear-wheel drive versus Magnum's choice of rear-drive or all-wheel drive. Like the Magnum, the Charger seated five and could have either V6 or V8 power. Chargers came in three models: SE with a 250-horsepower 3.5-liter V6; R/T with Chrysler's 340-horsepower 5.7-liter Hemi V8; and high-performance SRT8, with a 425-hp 6.1-liter version of the Hemi V8. The 5.7 V8 had Chrysler's Multi-Displacement System, which deactivated four cylinders under light throttle conditions to save fuel. All Chargers had an automatic transmission: a four-speed with the V6 and a five-speed on other versions. Magnums also were available with a 2.7-liter V6, but that engine did not go into Chargers. Antilocking four-wheel disc brakes were standard, along with antiskid/traction control. Available but not standard on all were front side airbags and front/rear head-protecting curtain side airbags. SE models had 17-inch wheels; 18-inchers were optional on the SE and standard on every other model except the SRT8s, which rode on 20-inch rubber. Charger R/T and SRT8 models added firmer suspension tuning. SRT8s also had Brembo-brand brakes, plus special seats and trim. Split folding rear seatbacks were standard on all except Charger SEs. Leather upholstery was standard on R/T and SRT8 models, optional on SE. Available were adjustable pedals, satellite radio, and Chrysler's UConnect hands-free wireless cell phone link. Available for Charger R/T was the Road/Track Performance Group with special suspension tuning and a 350-hp version of the 5.7 V8. A Daytona R/T Package, with the same engine, added throatier exhaust tuning and unique trim. Dodge's Charger competed against the Chrysler 300, Ford Five Hundred, and Ford Freestyle.
