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 brands.The naming convention used by SRT for its models are indicative of the vehicle's engine type.
