Powerful. Practical. Efficient. Challenger's versatile engine lineup doesn't just uphold its legendary performance reputation — it takes it to an entirely new level.
The 6.1-liter SRT® HEMI® V8 is the highest naturally aspirated specific-output engine ever offered in a Challenger. It features:
Performance-oriented camshaft profiles
Aggressively designed cylinder heads and intake and exhaust systems to help maximize airflow and increase engine speed
The 5.7-liter HEMI® V8 available with Multi-Displacement System (MDS) delivers:
Variable Cam Timing, bringing more power and optimal performance
Greater efficiency when equipped with MDS
Dual ignition (two spark plugs per cylinder) to increase peak power and torque
With the 5.7-liter HEMI®, Challenger R/T has 57 more horsepower and gets better highway fuel economy than Mustang GT
The 3.5-liter High-Output SOHC V6 engine offers:
Consistent speed and reduced emissions with a dual-tuned intake manifold and a sophisticated electronic throttle control system
Tailored pedal-movement response based on operating conditions
Even with a smaller V6 engine, Challenger SE has a 40-horsepower advantage over Mustang V6
