INTRODUCTION
The S213 E-Class facelift, launched in 2020, brought significant updates to Mercedes-Benz’s mid-size executive wagon. The E 450 4MATIC EQ Boost variant distinguished itself with its potent inline-six engine, mild-hybrid technology, and standard all-wheel drive. This model aimed to provide a luxurious and efficient driving experience, appealing to customers who prioritized both performance and practicality. The EQ Boost system, a 48-volt mild hybrid system, added a small electric motor to assist the engine, improving responsiveness and enabling features like extended coasting.
Powertrain & Engine Architecture
At the heart of the E 450 lies the M 256 3.0-liter inline-six cylinder engine. This engine is a marvel of modern engineering, featuring direct injection, a twin-scroll turbocharger, and a NANOSLIDE cylinder coating to reduce friction. The engine code M 256 is known for its smooth power delivery and efficiency. The EQ Boost system adds a 22 horsepower electric motor integrated into the drivetrain, providing an additional boost during acceleration and allowing for regenerative braking. The 9G-TRONIC nine-speed automatic transmission is standard, offering smooth and efficient gear changes. This transmission is electronically controlled and adapts to driving conditions for optimal performance. The transmission’s gear ratios are tuned to balance acceleration and fuel economy, with a focus on providing ample torque in everyday driving situations.
Driving Characteristics
The E 450 4MATIC EQ Boost delivers a refined and powerful driving experience. The combination of the inline-six engine and the EQ Boost system results in brisk acceleration, with 0-60 mph times around 4.9 seconds. The 9G-TRONIC transmission contributes to smooth and seamless gear changes, enhancing the overall driving comfort. The 4MATIC all-wheel-drive system provides excellent traction in various weather conditions. Compared to the E 350 models, the E 450 offers a noticeable increase in power and responsiveness. While not as overtly sporty as the AMG variants, the E 450 provides ample power for confident overtaking and highway cruising. The mild-hybrid system contributes to improved fuel economy, particularly in city driving, where the electric motor can assist the engine during start-stop cycles.
Equipment & Trim Levels
The E 450 4MATIC EQ Boost came generously equipped as standard. Key features included leather upholstery, heated and ventilated front seats, a premium sound system, and a large infotainment display with Mercedes-Benz’s MBUX system. MBUX offered voice control, augmented reality navigation, and a customizable user interface. Optional extras included a panoramic sunroof, advanced driver-assistance systems (such as adaptive cruise control and lane-keeping assist), and various interior trim options. The interior design emphasized luxury and comfort, with high-quality materials and meticulous attention to detail. The dashboard layout was clean and modern, with a focus on intuitive controls.
Chassis & Braking
The E 450 4MATIC featured a sophisticated suspension system designed to balance comfort and handling. The front suspension utilized independent multi-link setup, while the rear employed a multi-link independent suspension. This configuration provided a smooth and controlled ride, even on uneven surfaces. Ventilated disc brakes were standard on all four wheels, providing ample stopping power. The E 450 also included ABS (Anti-lock Braking System), electronic stability control, and traction control. The steering system was a speed-sensitive power steering rack and pinion, offering precise and responsive steering feel.
Market Reception & Comparison
The E 450 4MATIC EQ Boost was generally well-received by automotive critics. Reviewers praised its powerful engine, smooth transmission, and luxurious interior. The mild-hybrid system was also noted for its contribution to improved fuel economy. Compared to the E 350 models, the E 450 offered a significant performance upgrade, justifying its higher price tag. However, some critics noted that the E 450 lacked the outright sportiness of the AMG variants. In terms of reliability, the M 256 engine has proven to be relatively robust, although regular maintenance is essential. Fuel economy figures were competitive for its class, with combined fuel consumption ranging from 29 to 27 US mpg.
Legacy
The Mercedes-Benz E 450 4MATIC EQ Boost represents a significant step forward in the evolution of the E-Class. Its combination of power, efficiency, and luxury has made it a popular choice among discerning buyers. The M 256 engine is expected to remain a reliable and durable powertrain for years to come. On the used car market, these models hold their value well, reflecting their desirable features and reputation for quality. As technology continues to advance, the E 450 4MATIC EQ Boost will be remembered as a transitional model, bridging the gap between traditional internal combustion engines and the future of electrified vehicles.
