What is SRT?
Street and Racing Technology, the in-house performance division behind Dodge, Chrysler, Jeep, and Ram's fastest models.
SRT stands for Street and Racing Technology. It is the performance arm that builds the hottest versions of Dodge, Chrysler, Jeep, and Ram vehicles, and it is the American answer to badges like AMG at Mercedes or Nismo at Nissan.
The group grew out of the skunkworks teams that built the Viper and the Prowler. Those became Performance Vehicle Operations in 2002, and the SRT name arrived in 2004. Early cars set the template: the Neon SRT-4 was a cheap turbocharged four that embarrassed far pricier machinery, and the SRT-8 badge put a 6.1-liter Hemi V8 in the Charger, the Magnum, the 300C, and the Grand Cherokee. The 6.4-liter that replaced it is the one people now just call the 392.
What made SRT famous is the supercharged 6.2-liter Hemi introduced on the 2015 Challenger and Charger Hellcat, rated at 707 horsepower. The Redeye pushed that to 797, the Jeep Grand Cherokee Trackhawk carried the same engine at 707, and the Challenger SRT Demon reached 840 on race fuel. The widebody fender treatment on later Hellcats exists to cover the wider tires that much power requires.
SRT spent a short stretch as its own standalone brand, selling the 2013 to 2014 Viper as an SRT rather than a Dodge, before folding back under Dodge. In 2021 Stellantis dissolved the separate SRT team and moved its engineers into the wider company engineering organization, so the badge now signals the performance tier rather than a distinct in-house shop.
