Street & Racing Technology


Street & Racing Technology 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. This was renamed Performance Vehicle Operations from January 2002 till 2004. Since all PVO vehicles used the "SRT" brand, the development team itself 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 is indicative of the vehicle's engine type. The number that follows the "SRT" prefix denotes the number of engine cylinders. 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 Dodge Challenger Demon with a quarter mile time of 9.65 seconds, the 2015 Dodge Charger Hellcat with a quarter mile time of 11.0 seconds, the 2013 Dodge Viper 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. 2011-2014 SRT-8 versions have 392 HEMI engine, rated at and.
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 Dodge Challenger and Charger models 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 in 2003 and 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.

6-cylinder engines

The Crossfire SRT-6 never had a SRT-made engine, instead sourcing the M112k engines from Mercedes-Benz,, 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-liter naturally aspirated HEMI V8 engine that made. However, the Jeep Grand Cherokee SRT-8 only had. Their second unit is a 6.4-liter naturally aspirated Apache V8 engine that originally made but was upgraded to produce 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 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 1500 SRT-10. The first unit, an 8.3-liter naturally aspirated Viper V10 had made. The second unit used a larger bore and stroked 8.4-liter naturally aspirated Viper V10, which increased the power output to. The last generation Viper used a brand new engine, but still kept the 8.4-liter displacement. The engine produced, which then increased to 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.
