SRT vs R/T vs Scat Pack

On modern Dodges the badges climb in a fixed order. Using the final (2023) Challenger lineup as the example:

  • R/T (Road/Track) — 5.7L HEMI V8, 375 hp.
  • R/T Scat Pack — 6.4L (392) HEMI V8, 485 hp.
  • SRT Hellcat — supercharged 6.2L HEMI V8, 717 hp; SRT Hellcat Redeye 797 hp.
  • SRT Demon 170 — 1,025 hp on E85 (about 900 hp on pump gas), Dodge's most powerful car.

The 2024-and-later Charger uses new names — R/T and Scat Pack with the twin-turbo SIXPACK inline-six, and the electric Charger Daytona Scat Pack. See Dodge Charger vs Challenger and the fastest Dodge ranking. On the truck side, Ram's TRX is explained in what does TRX stand for?

Before you buy a used SRT

A used SRT is a specialty purchase: check model-year patterns in Dodge Challenger years to avoid and Dodge Charger years to avoid, overall Dodge reliability by model, and how prices fall with Dodge Charger depreciation.

FAQ

What does SRT stand for?

SRT stands for Street and Racing Technology. It is the name of the Chrysler (now Stellantis) high-performance engineering group that grew out of the team that developed the Dodge Viper, and the badge it puts on its fastest Dodge, Chrysler, Jeep and Ram models.

What is the difference between SRT and R/T?

R/T (Road/Track) is a Dodge trim name used on the mainstream V8 or upper-trim versions of a model, while SRT models are engineered by the performance group and sit above R/T and Scat Pack with more power, bigger brakes and track-focused suspension. On the 2023 Challenger, for example, the R/T had a 375-hp 5.7L V8 and the SRT Hellcat a 717-hp supercharged 6.2L V8.

Is SRT a brand?

Briefly. Chrysler ran SRT as a separate brand from 2012, selling the 2013–2014 car as the SRT Viper, then folded it back into Dodge in May 2014. In July 2025 Stellantis said it was bringing SRT back as a dedicated performance division working across Chrysler, Dodge, Jeep and Ram, rather than as a standalone brand.

What was the first SRT car?

The first SRT-badged vehicles were the 2003 Dodge Viper SRT-10 and the 2003 Dodge Neon SRT-4. The group that built them took the SRT name itself in 2004.

Which SRT models are sold new today?

For the 2026 model year Dodge sells the Durango SRT Hellcat, rated at 710 hp from a supercharged 6.2L HEMI V8. The Charger and Challenger SRT models ended with the 2023 model year, when the previous-generation cars went out of production.
