"The Dodge Challenger R/T features the new-generation 5.7-liter HEMI® V-8 engine with a five-speed automatic transmission that produces an estimated 370 horsepower (276 kW) and 398 lb.-ft. of torque (540 N•m). For 2009, the HEMI engine is upgraded to get an estimated five percent improvement in fuel economy as well as an increase of 30 horsepower (9 percent) and 8 lb.-ft. improved torque (2 percent) over a greater range of engine speeds. The automatic transmission features fuel-saving multi-displacement (MDS) technology which increases fuel economy by as much as 20 percent depending on driving conditions without sacrificing vehicle performance. The Dodge Challenger R/T also offers a precision-shift six-speed manual transmission — the first for a new-generation HEMI-powered car — that produces 375 horsepower (280 kW) and 404 lb.-ft. of torque (548 N•m) when running on premium fuel. The Dodge Challenger R/T can go from zero to 60 mph in less than six seconds."
