Street and Racing Technology (SRT) is an American badge of high-performance vehicles manufactured by Stellantis North America, mainly ones of the Dodge and Ram brands, with several future models planned encompassing the Dodge, Ram, and Jeep brands.

Origins of the badge date back to 1989 when a team known as "Team Viper" was organized to develop the Dodge Viper. It later merged with Team Prowler, the developers of the Plymouth Prowler, to become Specialty Vehicle Engineering (SVE). This was renamed Performance Vehicle Operations (PVO) from January 2002 until around 2004. Since all PVO vehicles used the SRT badge, the development team itself was renamed to SRT in 2004. SRT is used by vehicles of Dodge, Chrysler, and Jeep brands, including police models for Chrysler/FCA Fleet Division.

Cars

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 SRT8. 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 SRT8 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. With the improved engine, the current SRT8 model is not only faster than the previous model but also has better fuel efficiency than the previous one.

In 2012, Chrysler implemented a plan to turn SRT into a separate brand under the Chrysler Group umbrella. During the 2013 and 2014 model years, the Dodge Viper was sold under the model name SRT Viper. In May 2014, the SRT brand was re-consolidated under Dodge, with former SRT CEO Ralph Gilles continuing as senior vice president of product design and also as the CEO and president of Motorsports.

The Jeep Grand Cherokee SRT8 is being sold in China by dealer import methods. Due to increasing interest in American muscle cars, dealers were considering also importing the Dodge Charger and Challenger SRT8 into China. However, little to none of the Charger and Challenger imports to China have been confirmed.

After two years of SRT as an independent division, Fiat Chrysler Automobiles (now Stellantis) announced on May 4, 2014, that the SRT family of vehicles will be consolidated under the Dodge brand. This includes renaming the SRT Viper back to the Dodge Viper. This will expand the Dodge lineup to focus on it as a performance-dedicated brand.

In late 2014, FCA announced a new variant of the Dodge Challenger and Charger models named "SRT Hellcat" and another variant called the "SRT Demon" in early 2017.

Manufacturer engines

SRT has made six engines so far, and one derived engine. Their first two engines were the third generation ZB I's 8.3 L naturally aspirated Viper V10 and the Neon SRT-4's 2.4 L turbocharged I4.

4-cylinder engines SRT's 2.4 L turbocharged I4 for the Neon SRT-4 had produced in 2003 and later in 2004 and 2005. Another 2.4 L I4 was made, but this time was based on the Chrysler World Engine, and was made for the Caliber SRT4. That engine was rated at .

6-cylinder engines The Crossfire SRT-6 never had a SRT-made engine, instead sourcing the M112k engines from Mercedes-Benz (used in the Mercedes C32 AMG and SLK32 AMG) which produced .

8-cylinder engines SRT has built four V8s, which it has applied to five vehicles: Chrysler 300, Dodge Challenger, Dodge Charger, Dodge Magnum, and Jeep Grand Cherokee. Their first V8 was a 6.1 L naturally aspirated Hemi V8 engine that made . However, the Jeep Grand Cherokee SRT8 only had . Their second unit is a 6.4 L naturally aspirated Apache V8 engine that originally made but was upgraded to produce after 2014. SRT's most powerful variant is a 6.2 L supercharged V8, with two separate units used on the Hellcat and Demon models. The Hellcat's version makes and the Demon's makes . On 100-octane fuel, though, the Demon's engine makes .

10-cylinder engines SRT's 10-cylinder engines have only been used in two models, the Viper and the Ram SRT-10. The first versions, the 8.3 L naturally aspirated Viper V10, produced . The second version used a larger bore and stroked 8.4 L naturally aspirated Viper V10, which increased the output to . The last generation Viper used a brand new engine, but still kept the 8.4 L displacement. The engine produced , which then increased to after the Dodge-SRT absorption.
