The Chrysler 300 5.7i V8 AWD (340 Hp) represents a significant iteration of the revitalized 300 series, produced between 2005 and 2010. This variant occupied a premium position within the lineup, offering a blend of American V8 power, all-wheel drive capability, and a relatively luxurious interior. It was a key model in Chrysler’s attempt to recapture a segment of the large sedan market traditionally dominated by domestic rivals. The 300, built on the LX platform, aimed to provide a modern interpretation of classic American rear-wheel-drive styling and performance. This specific configuration, combining the 5.7-liter HEMI V8 with an automatic transmission and all-wheel drive, was targeted towards buyers seeking a comfortable, capable, and powerful full-size sedan.

Powertrain & Engine Architecture
The heart of the Chrysler 300 5.7i AWD is the EZB engine code, a 5.7-liter (345 cubic inch) HEMI V8. This engine utilizes a cast iron block with aluminum cylinder heads, a configuration designed for durability and performance. The engine employs multi-port fuel injection, delivering fuel directly to each cylinder for optimized combustion. The overhead valve (OHV) valvetrain, while a more traditional design compared to overhead cam engines, contributes to the engine’s low-end torque characteristics. The 5.7L HEMI is known for its Multi-Displacement System (MDS), which allows the engine to deactivate four cylinders under light load conditions, improving fuel economy. The engine is longitudinally mounted, sending power to all four wheels through a five-speed automatic transmission. This transmission, while providing smooth shifts, wasn’t known for being particularly sporty or quick to respond compared to some contemporary automatic gearboxes.
Driving Characteristics
The 300 5.7i AWD delivers a distinctly American driving experience. The engine provides ample low-end torque, making it effortless for everyday driving and confident for highway passing. While 340 horsepower is substantial, the car’s considerable weight (approximately 4,266 pounds) limits outright acceleration. The automatic transmission, while smooth, isn’t particularly aggressive in its shift points. Compared to the rear-wheel-drive 300 models, the AWD system adds weight and a slight reduction in fuel economy, but significantly enhances traction, particularly in inclement weather. Compared to the 3.5L V6 models, the 5.7L offers a substantial performance upgrade, but the higher-output SRT8 variant provides a much more focused and aggressive driving experience.
Equipment & Trim Levels
The 5.7i AWD trim typically included features such as leather upholstery, power-adjustable front seats, a premium sound system, and automatic climate control. Standard safety features included ABS, traction control, and multiple airbags. Optional extras included a navigation system, sunroof, and upgraded wheels. The interior design, while comfortable, leaned towards a more traditional American aesthetic, with a focus on spaciousness rather than cutting-edge design. The trim level sat comfortably between the base V6 models and the high-performance SRT8, offering a balance of luxury and performance.
Chassis & Braking
The Chrysler 300 5.7i AWD utilizes a traditional body-on-frame construction, contributing to its robust feel. The front suspension employs a spring strut design, while the rear features a multi-link setup with a transverse stabilizer bar. The braking system consists of ventilated discs at the front and solid discs at the rear. While adequate for everyday driving, the braking system wasn’t particularly noteworthy in terms of performance or feel. The all-wheel-drive system is primarily reactive, engaging the front wheels when rear wheel slip is detected.
Market Reception & Comparison
The Chrysler 300 5.7i AWD was generally well-received by critics as a capable and comfortable large sedan. However, its fuel economy was often criticized, particularly compared to some of its Japanese and European rivals. Reliability was also a concern for some owners, with reports of issues related to the transmission and electrical systems. Compared to the V6 models, the 5.7i offered a significant performance boost, but at a higher price point and with reduced fuel efficiency. The SRT8 variant, with its more powerful engine and sport-tuned suspension, appealed to a different segment of buyers seeking a more performance-oriented experience.
Legacy
The Chrysler 300 5.7i AWD, while not without its flaws, remains a popular choice in the used car market. The HEMI V8 engine is generally considered durable, although regular maintenance is crucial. The automatic transmission can be prone to issues if not properly serviced. The availability of parts is generally good, and the car’s relatively simple design makes it accessible for DIY repairs. Today, the 300 5.7i AWD represents a nostalgic reminder of a time when American automakers prioritized large displacement engines and rear-wheel-drive platforms. It continues to appeal to buyers seeking a comfortable, powerful, and uniquely styled full-size sedan.
