The naming convention used by SRT for its models is indicative of the vehicle's engine type. The number that follows the "SRT" prefix denotes the number of engine cylinders. For example, Chrysler 300C models with 6.1 L Hemi V8s when in the SRT version are named as the Chrysler 300C SRT-8. Similarly, the Dodge Viper SRT-10 along with the Dodge Ram SRT-10 had an 8.3 L V10. Currently, the quickest SRT production models are the 2023 Dodge Challenger Demon 170 with a quarter-mile time of 8.91 seconds, the 2021 Dodge Challenger SRT Super Stock with a quarter-mile time of 10.5 seconds, and the 2021 Dodge Charger SRT Hellcat RedEye with a quarter-mile time of 10.6 seconds. Chrysler released the 6.4 L Hemi engine in early 2011. 2011-2014 SRT-8 versions have 392 Hemi (6.4 L) engine, rated at and . The engine was used in the 2012 Dodge Challenger SRT8, Dodge Charger SRT8, Chrysler 300 SRT8, and the Jeep Grand Cherokee SRT8.
