Street and Racing Technology — SRT — is Stellantis’ performance sub-brand, responsible for the Hellcat, Demon, Demon 170, and TRX models. MoparInsiders covers every SRT vehicle past and present, from the now-collectible Durango SRT Hellcat Road Predator in Mexico to the Chrysler 300 SRT Hellcat Redeye we wish had been built. We track the future too — whether Hellcat power returns to the Charger and if the Grand Cherokee SRT will return. For Demon 170 collector data, see the production-numbers reference.
