A dual-tuned intake manifold utilizes a short runner valve, bringing you 250 horses at 6800 rpm and 250 lb-ft of torque at 3800 rpm. Partnered with a sophisticated electronic throttle control system that tailors the pedal-movement response based on operating conditions, plus platinum-tip spark plugs and the coil-on-plug ignition system, you'll reap benefits like more consistent speed and reduced emissions (standard on SE).

Want more? The 5.7-liter HEMI® V8 engine is bringing it. More power comes from Variable Cam Timing — you'll get 370 horsepower and 390 lb-ft of torque, not to mention more versatility when equipped with the available Multi-Displacement System (MDS). With this feature, the engine will switch from eight cylinders to four in highway traffic or during cruising, creating the perfect balance between power and efficiency (standard with five-speed AutoStick®).

Packing 425-horsepower and 420 lb.-ft. of torque at 4800 rpm, this is the highest naturally aspirated specific-output engine ever offered in a Challenger. Performance-oriented camshaft profiles, with aggressively designed cylinder heads and intake and exhaust systems, help maximize airflow and increase engine speed. Other components including a reinforced engine block with increased coolant flow, forged steel crankshaft, high-strength powdered-metal connecting rods, floating-pin pistons and an oil pan that minimizes oil foaming, further strengthen this powerhouse. The HEMI® Orange-painted cylinder block and black valve covers are icing on the cake.
