Street & Racing Technology (commonly called SRT) is a high-performance automobile group within Fiat Chrysler Automobiles. 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) in January of 2002. Since all PVO vehicles used the SRT name, the PVO development group was renamed SRT in 2004. SRT heavily tunes and 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. The number that follows the "SRT" prefix denotes the number of engine cylinders the vehicle has. For example: the Chrysler 300C SRT8 has a 6.1 liter Hemi V-8; Therefore, the SRT version is known as the Chrysler 300C SRT-8. Similarly, the Dodge Viper SRT-10 along with the Dodge Ram SRT-10 had an 8.3 L V-10.
Currently the fastest SRT production models are the 2018 Challenger Demon with a quarter mile time of 9.65 seconds, the 2015 Charger Hellcat with a quarter mile time of 11.0 seconds, the 2013 Dodge Viper SRT with a quarter mile time of 11.1 seconds, and the 2015 Challenger Hellcat with quarter mile time of 11.2 seconds. Other SRT models have recorded quarter mile performances, from 12.8 seconds for the AMG-based Chrysler Crossfire SRT-6 to the Dodge Neon SRT-4 at 13.9 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. With the improved engine, current SRT8 model are 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.
In late 2014, Chrysler announced a new variant of the SRT named "SRT Hellcat" and another variant called the "SRT Demon" in early 2017.

Future and concept vehicles
In terms of future cars, the only car to be considered for the future is the SRT Tomahawk, which is a Vision Gran Turismo car. The car's projected production start is around the year 2035, but SRT is waiting until technology catches up so they can produce the car, since the car shows what "supercars could look like in 20 years".
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-liter naturally aspirated Viper V10 and the Neon SRT-4's 2.4-liter turbocharged Inline-4.
4-cylinder engines
SRT's 2.4-liter turbocharged Inline-4 for the Neon SRT-4 had produced 215 hp (160 kW; 218 PS) in 2003 and 230 hp (172 kW; 233 PS) later in 2004 and 2005. Another 2.4-liter inline-4 was made, but this time was based on the Chrysler World Engine, and was made for the Caliber SRT-4. That engine made 285 hp (213 kW; 289 PS).
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 350 hp (261 kW; 355 PS).
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-liter naturally aspirated HEMI V8 engine that made 425 hp (317 kW; 431 PS). However, the Jeep Grand Cherokee SRT-8 only had 420 hp (313 kW; 426 PS). Their second unit is a 6.4-liter naturally aspirated Apache V8 engine that originally made 470 hp (350 kW; 477 PS) but was upgraded to produce 485 hp (362 kW; 492 PS) after 2014. SRT's most powerful variant is a 6.2-liter supercharged V8, with two separate units used on the Hellcat and Demon models. The Hellcat's version makes 707 hp (527 kW; 717 PS) and the Demon's makes 808 hp (603 kW; 819 PS). On 100-octane fuel, though, the Demon's engine makes 840 hp (626 kW; 852 PS).
10-cylinder engines
SRT's 10-cylinder engines have only been used in two models, the Viper and the Ram 1500 SRT-10. The first unit, an 8.3-liter naturally aspirated Viper V10 had made 500 hp (373 kW; 507 PS). The second unit used a larger bore and stroked 8.4-liter naturally aspirated Viper V10, which increased the power output to 600 hp (447 kW; 608 PS). The last generation Viper used a brand new engine, but still kept the 8.4-liter displacement. The engine produced 640 hp (477 kW; 649 PS), which then increased to 645 hp (481 kW; 654 PS) after the Dodge-SRT absorption.
SRT in China
The Jeep Grand Cherokee SRT-8 is being sold in China by dealer import methods. Due to increasing interest in American muscle cars, dealers are considering also importing the Dodge Charger and Challenger SRT-8 into China.
Chrysler Group leadership changes
After two years of SRT as an independent division, the recently formed Fiat Chrysler Automobiles "FCA" 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 again to the legendary "Dodge Viper". This will expand the Dodge lineup to focus it as a performance-dedicated brand.
