# Street and Racing Technology

Street and Racing Technology (SRT) is an American badge of high-performance vehicles manufactured by Stellantis, mainly ones of the Dodge brand.
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 SRT-8. 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 SRT-8 versions have 392 Hemi (6.4 L) engine, rated at 470 hp (350 kW) and 470 lb⋅ft (637 N⋅m). 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 SRT-8 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 SRT-8 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 215 hp (160 kW; 218 PS) in 2003 and 230 hp (172 kW; 233 PS) 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 SRT-4. That engine was rated at 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 L 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 L 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 L 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 versions, the 8.3 L naturally aspirated Viper V10 produced 500 hp (373 kW; 507 PS). The second version used a larger bore and stroked 8.4 L naturally aspirated Viper V10, which increased the output to 600 hp (447 kW; 608 PS). The last generation Viper used a brand new engine, but still kept the 8.4 L 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.
