Positioned as the flagship model, it aimed to recapture the spirit of the original 1950s Chrysler 300 “letter series” cars, offering a blend of American muscle car power and full-size sedan luxury. This variant was exclusively offered with a naturally aspirated 6.4-liter HEMI V8 engine paired with a five-speed automatic transmission, making it a distinct offering within the 300 lineup, which also included V6 and smaller V8 options.

Technical Specifications

INTRODUCTION

The 2012-2014 Chrysler 300 SRT8 6.4 HEMI V8 Automatic was a performance-oriented iteration of the second-generation Chrysler 300. Building upon the redesigned 300 introduced in 2011, the SRT8 variant aimed to deliver a more engaging driving experience and a higher level of performance than the standard models. It served as a halo car for the 300 lineup, attracting buyers seeking a powerful, rear-wheel-drive sedan with a distinctive American character. The “SRT” designation, standing for Street and Racing Technology, signified a focus on performance enhancements developed by Chrysler’s dedicated performance division.

Powertrain & Engine Architecture

The heart of the 300 SRT8 is the 6.4-liter (392 cubic inch) HEMI V8 engine, internally designated as the ESG. This engine is a member of Chrysler’s Generation III HEMI family, featuring overhead valve (OHV) valvetrain, multi-port fuel injection, and a cast iron block with aluminum cylinder heads. The 6.4L engine benefits from increased bore size compared to the 5.7L HEMI, resulting in a larger displacement and increased power output. The engine produces 470 horsepower at 6,000 rpm and 470 lb-ft of torque at 4,300 rpm. The engine’s robust bottom end and efficient cylinder heads contribute to its strong low-end torque and responsive throttle characteristics.

The engine is mated to a five-speed automatic transmission (545RFE) designed to handle the substantial power output. While not the most modern transmission by 2012 standards (many competitors were moving to six or eight-speed automatics), the 545RFE was known for its durability and relatively smooth shifts. The transmission features AutoStick, allowing the driver to manually select gears, though it lacks the responsiveness of modern paddle-shift systems. The powertrain configuration is longitudinal, with the engine mounted north-south and driving the rear wheels.

Driving Characteristics

The 300 SRT8 delivers a distinctly American driving experience. The 6.4-liter HEMI provides ample power for brisk acceleration and effortless highway cruising. The rear-wheel-drive layout contributes to a balanced feel, although the car’s considerable weight (approximately 4,365 lbs) is noticeable during spirited cornering. The five-speed automatic transmission, while reliable, isn’t as quick-shifting or fuel-efficient as more modern transmissions. The gear ratios are tuned for acceleration, prioritizing strong off-the-line performance and mid-range punch. Compared to the V6 models, the SRT8 offers a significantly more engaging and powerful driving experience. Compared to the 5.7L Hemi, the 6.4L provides a substantial increase in both horsepower and torque, resulting in noticeably quicker acceleration times.

Equipment & Trim Levels

The 300 SRT8 came standard with a comprehensive list of features, reflecting its position as the top-of-the-line model. Standard equipment included leather upholstery, heated and ventilated front seats, a premium sound system, a touchscreen infotainment system, and a power sunroof. Exterior features included unique SRT-specific styling cues, such as a distinctive front grille, rear spoiler, and 20-inch alloy wheels. Optional extras included a dual-pane sunroof, upgraded audio systems, and various appearance packages. The interior typically featured dark, sporty trim with SRT badging throughout.

Chassis & Braking

The 300 SRT8 featured a performance-tuned chassis designed to handle the increased power. The suspension utilized a double wishbone front suspension and an independent multi-link rear suspension, with stiffer springs and dampers compared to the standard 300 models. Stabilizer bars were also upgraded to reduce body roll during cornering. Braking duties were handled by ventilated disc brakes at all four corners, providing ample stopping power. The SRT8 also included ABS (Anti-lock Braking System) as standard equipment. The steering system employed an electric power steering system, offering a balance of feel and efficiency.

Market Reception & Comparison

The 300 SRT8 was generally well-received by automotive critics, who praised its powerful engine, comfortable ride, and distinctive styling. However, some reviewers noted the car’s weight and the somewhat dated five-speed automatic transmission. Compared to European performance sedans, the 300 SRT8 offered a different kind of appeal – prioritizing raw power and a comfortable, spacious interior over razor-sharp handling. Fuel economy was also a point of criticism, with combined fuel consumption averaging around 17 mpg. The 300 SRT8 offered a compelling alternative to other American muscle cars, such as the Dodge Charger SRT8, and provided a more luxurious and refined experience than many of its competitors.

Legacy

The Chrysler 300 SRT8 6.4 HEMI V8 Automatic remains a popular choice among enthusiasts seeking a powerful and affordable rear-wheel-drive sedan. The 6.4-liter HEMI engine is known for its reliability and durability, and the five-speed automatic transmission, while not cutting-edge, has proven to be robust. On the used car market, the 300 SRT8 typically commands a higher price than the standard 300 models, reflecting its performance capabilities and exclusivity. The car represents a modern interpretation of the classic American muscle car, offering a blend of power, comfort, and style that continues to appeal to a wide range of buyers.
