The 2008-2009 Dodge Challenger cars (SE, R/T, and Challenger SRT8)Powering the Dodge Challenger R/T is a revised 5.7-liter HEMI V-8 engine producing 370 horsepower (276 kW) with a five-speed automatic, and 375 hp (280 kW) with a six-speed manual transmission. The engines belt out 398 lb-ft (540 Nm) and 404 lb-ft (548 Nm) of torque, respectively; the Challenger R/T can do 0-60 in under six seconds, bone stock. The manual-transmission Challenger R/T has numerous differences from the automatic aside from the transmission itself, using a variable displacement power steering pump, different rear shocks, and other tuning changes — and the ability to shut off the ESP completely, rather than having it in “rescue” mode. The gas mileage for the manual transmission is a little lower than the automatic, because it cannot have the multiple-displacement system (cylinder shutoff). A special-edition Dodge Challenger Classic R/T will be available later in the 2009 model year, with B5 blue paint, black side stripes, unique badging, and 20-inch five-spoke aluminum wheels. The 2009 Challenger SRT8 keeps its 425 horsepower V8, while adding a stick-shift option; it can do 0-60 in under five seconds. The Dodge Challenger SE, powered by the 3.5-liter V-6, uses a four-speed automatic. For 2009, the Hemi engine was upgraded to get 5% higher gas mileage, and more power, especially at lower engine speeds for a better off-the-line feel, thanks to variable cam timing, an expanded MDS operating range, an increased compression ratio, improved port flow, and reduced restriction exhaust and induction. Other updates are crankshaft structural upgrades, a dual-mass crankshaft damper, floating pin piston design, valve spring design and oil pump capacity increase for VVT. (Again, manuals can’t use MDS — yet).
