Street and Racing Technology

Street & Racing Technology (commonly called SRT) is a high-performance automobile group within Chrysler LLC. SRT began as "Team Viper" 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). Since all PVO vehicles used the SRT name, it was decided in 2004 to use that name for the development group as well. SRT produces vehicles for the Chrysler, Dodge and Jeep Vehicles.

The naming convention used by SRT for its models are indicative of the vehicle's engine type. The number that follows the "SRT" prefix denotes the number of engine cylinders the vehicle has. For example the Chrysler 300C has a 5.7L Hemi V-8; Therefore the SRT version is known as the Chrysler 300C SRT-8, which has a 6.1L Hemi V-8. Similarly, the Dodge Viper SRT-10 along with the Dodge Ram SRT-10 have an 8.3L V-10.

Currently the fastest SRT production models are the 2010 Dodge Viper SRT-10 series with a recorded quarter mile time of 11.7 seconds. The other SRT models have recorded quarter mile performances from 12.8 seconds for the AMG-based Chrysler Crossfire SRT-6 to the Dodge Caliber SRT-4 at 14.6 seconds.

Chrysler released the 6.4L Hemi engine in early 2011. New SRT-8 versions have 392 HEMI (6.4L) engine, rated at 470 hp (350 kW) and 470 lb·ft (637 N·m).

The new engine is used in the 2012 Dodge Challenger SRT8, Dodge Charger SRT8, Chrysler 300 SRT8 and the Jeep Grand Cherokee SRT8.

Chrysler has recently announced plans to turn SRT into a separate brand (a la RAM). Models would include the Viper and the upcoming Barracuda.
