How many Litres is the SRT Charger?
The SRT Charger does not have a single displacement. It has used engines ranging from 6.1 to 6.4 to 6.2 litres, depending on the model year and variant.
To understand the answer, it helps to trace the Charger SRT’s evolution from the early SRT8 years through the 392-powered variants and into the modern Hellcat family, where the displacement stayed at 6.2 litres but tuning and horsepower changed over time.
Engine sizes by SRT Charger variant
Below are the core litre measurements associated with the main SRT Charger variants across its production history. Note that horsepower and tuning evolved separately from displacement.
- SRT8 (2008–2010): 6.1 L Hemi V8 (372 cu in)
- SRT 392 / SRT8 392 (2011–2019): 6.4 L Hemi V8 (392 cu in)
- SRT Hellcat (2015–2023): 6.2 L Supercharged Hemi V8 (707 hp in standard Hellcat)
- SRT Demon-related variants for Charger were not produced; however, the Redeye and Jailbreak iterations kept the 6.2 L base with higher output (797 hp for Redeye, 807 hp for Jailbreak)
In summary, the SRT Charger’s displacement sits at 6.1 L for the earliest SRT8 models, 6.4 L for the 392 variants, and 6.2 L for the Hellcat lineage and its high-horsepower siblings.
Summary
The SRT Charger’s litres depend on the model line: 6.1 L for the original SRT8, 6.4 L for the 392-era versions, and 6.2 L for the Hellcat family (with tuned variants such as Redeye and Jailbreak increasing horsepower while keeping the same 6.2 L engine). There isn’t a single figure that applies to all SRT Chargers; displacement varies by generation and trim.
