SRT Vs SRT8: What Are The Differences? [Explained]

In the world of high-performance vehicles, two monikers have made a significant impact in the automotive industry: SRT and SRT8. Affiliated with Dodge and Chrysler vehicles, these designations represent some of the most impressive performance models in their respective lineups.

In this in-depth article, we will explore the primary differences between SRT and SRT8, focusing on the detailed technical aspects such as performance upgrades, engine specifications, and unique features that set these two designations apart.

In essence, SRT8 is a specific trim level under the SRT (Street and Racing Technology) division, offering enhanced performance and exclusive features compared to standard SRT models.

SRT: Street and Racing Technology

SRT Origins and Mission

SRT, which stands for Street and Racing Technology, is a high-performance division within the Chrysler Group, encompassing brands like Dodge, Chrysler, and Jeep.

Founded in the early 2000s, the SRT division was established with the purpose of designing, engineering, and building performance-focused vehicles with improved power, handling, and style. SRT models generally feature upgraded engines, suspensions, brakes, and aerodynamics compared to their standard counterparts.

SRT Performance Features

SRT models come equipped with an array of performance-oriented features that distinguish them from standard vehicles. Some of these features include:

  • High-performance engines: SRT models usually feature larger-displacement engines with more horsepower and torque than standard models. For example, the Dodge Charger SRT comes with a 6.2-liter HEMI V8 engine producing 707 horsepower and 650 lb-ft of torque, while the standard Charger model has a 3.6-liter V6 engine with 292 horsepower and 260 lb-ft of torque.
  • Performance-tuned suspensions: SRT vehicles are equipped with specially-tuned suspensions designed to improve handling and stability during high-performance driving. These suspensions typically include stiffer springs, dampers, and sway bars to reduce body roll and maintain better control during aggressive maneuvers.
  • Brembo brakes: SRT models feature Brembo brakes, which are renowned for their excellent stopping power and heat dissipation capabilities. These high-performance brakes come with larger rotors and calipers, which provide superior braking performance during high-speed driving.
  • High-performance tires: SRT vehicles are fitted with performance tires that offer improved grip and traction on various surfaces. These tires are often wider and have a stickier compound to maximize contact with the road.
  • Sporty exterior styling: SRT models come with unique exterior design elements, including distinctive SRT badging, aggressive front and rear fascias, and larger air intakes for improved engine cooling.

SRT8: The Ultimate Performance Package

SRT8: A Step Above SRT

SRT8 is a specific trim level within the SRT lineup, representing the zenith of performance for a given model. SRT8 vehicles offer even more performance upgrades, exclusive features, and premium materials compared to standard SRT models. These enhancements typically come in the form of engine upgrades, upgraded brakes, and unique interior and exterior styling.

SRT8 Engine Performance

SRT8 vehicles are powered by larger and more powerful engines compared to standard SRT models. Most SRT8 models are equipped with a 6.4-liter HEMI V8 engine, which offers significantly more horsepower and torque than the engines found in regular SRT models.

For instance, the 6.4-liter HEMI V8 engine in the Dodge Challenger SRT8 produces 470 horsepower and 470 lb-ft of torque, as opposed to the 6.2-liter HEMI V8 found in the standard Challenger SRT, which generates 707 horsepower and 650 lb-ft of torque. This increase in power results in faster acceleration and a higher top speed for SRT8 vehicles.

SRT8 Handling and Braking

SRT8 models feature upgraded suspensions and brakes, providing even better handling and stopping power. The performance-tuned suspensions are designed to handle the increased power output and offer improved cornering and stability.

SRT8 vehicles often feature adaptive damping systems, which adjust the suspension damping characteristics in real-time based on driving conditions and driver inputs.

The larger Brembo brakes on SRT8 models provide exceptional stopping power and are capable of handling the increased demands of high-performance driving. These braking systems often incorporate six-piston front calipers and four-piston rear calipers, which clamp down on larger, vented rotors for maximum heat dissipation and fade resistance.

SRT8 Exclusive Features and Styling

In addition to performance enhancements, SRT8 models also come with exclusive features and styling elements that set them apart from standard SRT models. Some of these exclusive features include:

  • Unique SRT8 badging and exterior accents: SRT8 vehicles feature distinctive badging and exterior trim elements, such as unique grilles, front splitters, and rear spoilers, which help to differentiate them from standard SRT models.
  • Upgraded interior materials: SRT8 models often come with premium interior materials, such as Nappa leather, Alcantara, and carbon fiber trim, which elevate the cabin’s aesthetics and provide a more luxurious feel.
  • SRT Performance Pages: SRT8 vehicles are equipped with SRT Performance Pages, an advanced system that displays performance metrics, such as 0-60 mph times, quarter-mile times, and g-forces, on the infotainment screen. This system also allows drivers to customize various performance settings, such as steering response, suspension stiffness, and throttle mapping.
  • Launch control: Many SRT8 models feature launch control, a system that optimizes acceleration from a standstill by modulating engine torque and managing wheel spin. This allows drivers to achieve the fastest possible acceleration times with minimal wheelspin.


In conclusion, the primary differences between SRT and SRT8 models lie in the level of performance and exclusive features offered. While both designations represent high-performance vehicles within the Chrysler Group, SRT8 models take performance and exclusivity to the next level.

With more powerful engines, upgraded handling, and premium materials, SRT8 models offer an even more exhilarating driving experience for those seeking the ultimate in performance and style.
