What cylinder is a Hellcat?

A Hellcat uses an eight-cylinder V8 engine.

In Dodge’s performance lineup, “Hellcat” refers to the 6.2-liter supercharged HEMI V8 that powers models such as the Challenger SRT Hellcat and Charger SRT Hellcat, and, in earlier years, the Jeep Grand Cherokee Trackhawk. The engine is a pushrod V8 with a supercharger, delivering exceptionally high horsepower across variants: about 707 hp in the base Hellcat, rising to roughly 797–807 hp in the higher-performance Redeye, Jailbreak, and Super Stock variants. Power figures vary by year and model configuration.

Engine configuration

The following details summarize the Hellcat’s core technical characteristics.

• Cylinders: 8 total


• Configuration: V8 (two banks of four cylinders)


• Displacement: 6.2 liters


• Induction: Supercharged


• Engine family: HEMI (hemispherical combustion chamber)


• Valve arrangement: Two valves per cylinder (pushrod design)

In short, the Hellcat is a high-performance, supercharged V8 designed for extreme straight-line speed within Mopar’s HEMI family.

Variants and power levels

Power outputs vary by variant and year, with the most commonly cited figures being:

• Standard Hellcat: ~707 horsepower


• Hellcat Redeye: ~797 horsepower


• Jailbreak and Super Stock variants: ~807 horsepower


• Jeep Grand Cherokee Trackhawk (uses the same engine in an SUV): ~707 horsepower

Notes: Exact horsepower can differ by transmission, exhaust, gearing, and tuning, and varies across model years and emissions regulations.

Where the engine appears

The Hellcat’s 6.2-liter supercharged HEMI V8 powers several vehicles across the Mopar lineup, most notably:

• Dodge Challenger SRT Hellcat


• Dodge Challenger SRT Hellcat Redeye


• Dodge Challenger SRT Jailbreak


• Dodge Charger SRT Hellcat


• Dodge Charger SRT Hellcat Redeye


• Jeep Grand Cherokee Trackhawk (limited production, SUV)

These applications share the same fundamental engine architecture, tuned for different performance targets.

Summary

The Hellcat is defined by its eight-cylinder, V8 configuration—the 6.2-liter HEMI engine with a supercharger—producing a range of horsepower from about 707 hp in standard form to around 807 hp in the top variants. It appears in Dodge Challenger and Charger models and, in SUV form, the Jeep Grand Cherokee Trackhawk, illustrating Mopar’s emphasis on extreme acceleration and straight-line speed.
