The Chrysler 300 II 5.7, a variant of the second-generation Chrysler 300 (LX platform), was produced from 2011 to 2014. This model represented a significant offering in the full-size American sedan segment, positioned as a more premium and performance-oriented alternative to mainstream competitors. The 5.7-liter HEMI V8 engine paired with an automatic transmission and all-wheel drive (AWD) system distinguished it as a capable and comfortable grand tourer. It occupied a mid-to-upper trim level within the 300 lineup, slotting above the base 3.6L V6 models but below the even more powerful 6.4L SRT-8.

Powertrain & Engine Architecture
The heart of the Chrysler 300 II 5.7 was the 5.7-liter HEMI V8 engine, internally designated as the EZH. This engine was a member of Chrysler’s third-generation HEMI family, featuring multi-displacement system (MDS) technology. MDS allowed the engine to deactivate four cylinders under light load conditions, improving fuel economy. The engine utilized a cast iron block with aluminum cylinder heads, and a hydraulic roller camshaft. Fuel delivery was managed by a multi-port fuel injection system. The 5.7L HEMI produced 363 horsepower at 5,150 rpm and 388 lb-ft of torque at 4,250 rpm. The engine’s robust construction and relatively simple design contributed to its overall reliability.
The engine was mated to a five-speed automatic transmission (545RFE). This transmission was known for its smooth shifting characteristics and durability. The all-wheel-drive system employed a transfer case to distribute power between the front and rear axles, enhancing traction in various weather conditions. The AWD system was primarily reactive, automatically engaging the front wheels when wheel slip was detected.
Driving Characteristics
The 5.7-liter engine provided ample power for the Chrysler 300 II, delivering brisk acceleration and effortless highway cruising. While not as overtly sporty as some of its competitors, the 300 offered a comfortable and refined driving experience. The automatic transmission was well-tuned for everyday driving, with smooth gear changes. The AWD system provided enhanced stability and confidence, particularly in inclement weather. Compared to the base 3.6L V6 models, the 5.7 offered a noticeable performance upgrade, while remaining more accessible than the high-performance SRT-8 variant. The 5-speed automatic, while adequate, was beginning to show its age compared to newer transmissions with more gears, impacting fuel economy at higher speeds.
Equipment & Trim Levels
The 5.7-liter AWD model typically came standard with features such as leather upholstery, heated front seats, a premium audio system, dual-zone automatic climate control, and power-adjustable front seats. Optional extras included a navigation system, a sunroof, and advanced safety features like adaptive cruise control and blind-spot monitoring. The exterior styling was generally upscale, with chrome accents and available alloy wheels. The interior design was functional and comfortable, though some critics noted the use of somewhat dated materials in certain areas.
Chassis & Braking
The Chrysler 300 II utilized a traditional body-on-frame construction, contributing to its substantial weight. The front suspension featured an independent McPherson strut design with coil springs and an anti-roll bar, while the rear suspension employed an independent multi-link setup. The braking system consisted of ventilated discs at all four corners, providing adequate stopping power. Anti-lock brakes (ABS) were standard. The steering was rack-and-pinion with electric power assist, offering a reasonably responsive feel.
Market Reception & Comparison
The Chrysler 300 II 5.7 AWD was generally well-received by automotive critics. It was praised for its spacious interior, comfortable ride, and powerful engine. However, its fuel economy was often criticized, particularly compared to newer, more efficient sedans. Compared to the V6 models, the 5.7 offered a significant performance boost, justifying the higher price tag for buyers seeking more power. The SRT-8 variant provided even greater performance, but at a considerably higher cost. Reliability was generally considered average for an American-made vehicle, with some reports of minor electrical issues.
Legacy
The Chrysler 300 II 5.7 AWD remains a relatively affordable and capable used car option. The 5.7L HEMI engine is known for its durability and relatively straightforward maintenance. While fuel economy is not its strong suit, the 300 offers a comfortable and spacious interior, along with a respectable level of performance. The AWD system adds a degree of all-weather capability, making it a practical choice for drivers in regions with harsh winters. As of today, these vehicles can be found in good condition with reasonable mileage, representing a value proposition for those seeking a large, American-made sedan with a powerful V8 engine.
