What is the rpm of the Hellcat?
The Hellcat lineup normally revs up to a redline of about 6,500 rpm. This applies to the main Challenger and Charger variants that use the 6.2-liter supercharged Hemi V8, including the higher-output Redeye versions, which share the same redline while delivering more horsepower and torque.
What the rpm figure means for a Hellcat
Rpm, short for revolutions per minute, measures how fast the engine crankshaft spins. The redline is the manufacturer-set upper limit designed to protect the engine from damage while still allowing high-performance driving. In the Hellcat’s turbocharged/supercharged V8 setup, the redline is chosen to balance boost stability, power delivery, and reliability across its various drive modes and gearing.
Variants and their redline
The main Hellcat variants use the same redline value, though horsepower and torque differ. The commonly cited redline for these engines is 6,500 rpm.
- Challenger SRT Hellcat
- Challenger SRT Hellcat Redeye
- Charger SRT Hellcat
- Charger SRT Hellcat Redeye
All of these models rely on the 6.2-liter supercharged Hemi V8, with a factory redline near 6,500 rpm. Actual tach behavior can vary slightly by model year, calibration, and driving mode, but the official limit remains around this figure.
Performance context
For most Hellcat variants, peak horsepower is achieved near the high end of the rev range—typically around 6,000 rpm—while the engine can reach its redline under aggressive acceleration or in manual-style rev-matching scenarios. The Redeye variants increase total output (up to around 797 horsepower) but generally maintain the same redline, with boost and torque curves shaping how quickly power builds as you approach the top end.
Notes and caveats
Exact redline figures can vary by model year, market calibration, and specific transmission settings. Always check the owner’s manual or the vehicle’s tachometer for the precise limit on your car. If you’re tracking or performing high-intensity driving, use the manufacturer’s recommended shift points and caution to protect the engine and drivetrain.
Summary
In short, the Hellcat’s engine redline sits around 6,500 rpm across the Challenger and Charger variants, including the Redeye models. The horsepower and torque profiles differ by variant, but the maximum engine speed is generally the same. For precise figures on a given car, consult the specific model year’s documentation or the tachometer readout.
