INTRODUCTION
The C238 E-Class Coupe, launched in 2017, represented a significant departure from its predecessor, adopting a more fluid and dynamic design language. The E 450 4MATIC, introduced in 2018, slotted into the lineup as a performance-oriented option, bridging the gap between the entry-level E 300 and the full-fledged AMG models. Built on the W213 E-Class sedan platform (internally known as the 1HX0), the Coupe offered a more sporting driving experience with its two-door configuration and refined powertrain options. The E 450 was produced for a relatively short period, ending in May 2019, making it a somewhat less common variant within the C238 generation.
Powertrain & Engine Architecture
At the heart of the E 450 lies the M276.823 engine, a 2.996-liter (182.83 cubic inches) V6 engine featuring twin turbochargers and direct fuel injection. This engine is part of Mercedes-Benz’s modular engine family, known for its efficiency and power density. The engine produces 367 horsepower at 5250-6000 rpm and 500 Nm (368.78 lb-ft) of torque between 1800-4500 rpm. The turbochargers are positioned within the V of the engine, contributing to a more compact design and improved responsiveness. The engine utilizes a DOHC (Double Overhead Camshaft) valvetrain with four valves per cylinder. Paired with the engine is the 9G-TRONIC nine-speed automatic transmission. This transmission is renowned for its smooth shifts and wide gear ratio spread, contributing to both fuel efficiency and performance. The 9G-TRONIC features a torque converter lockup clutch that engages in most gears, minimizing slippage and improving efficiency.
Driving Characteristics
The E 450 4MATIC delivers a refined and capable driving experience. The combination of the turbocharged V6 and the nine-speed automatic transmission provides ample power for both highway cruising and spirited driving. Acceleration from 0 to 60 mph is achieved in approximately 5.3 seconds. The 9G-TRONIC transmission is programmed to prioritize smooth shifts in Comfort mode, while Sport mode provides quicker response and holds gears longer. The 4MATIC all-wheel-drive system ensures excellent traction in all weather conditions, enhancing stability and confidence. Compared to the base E 300, the E 450 offers a noticeable increase in performance, particularly in mid-range acceleration. While not as aggressively tuned as the AMG variants, the E 450 provides a satisfying balance of power and comfort.
Equipment & Trim Levels
The E 450 4MATIC Coupe came standard with a generous array of features, including leather upholstery, heated and ventilated front seats, a panoramic sunroof, and a premium Burmester sound system. Standard safety features included automatic emergency braking, lane-keeping assist, and adaptive cruise control. Optional extras included a head-up display, massaging front seats, and a rear-seat entertainment system. Interior trim options ranged from wood veneers to aluminum accents, allowing buyers to personalize the cabin to their preferences. The dashboard layout was similar to that of the E-Class sedan, featuring a dual 12.3-inch display screen for the instrument cluster and infotainment system.
Chassis & Braking
The C238 E-Class Coupe features a sophisticated chassis design with an independent multi-link suspension at both the front and rear. The suspension is tuned to provide a comfortable ride while maintaining good handling characteristics. A transverse stabilizer bar is fitted to both axles to reduce body roll during cornering. The E 450 4MATIC is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) and Electronic Stability Program (ESP) are standard features, enhancing safety and control. The steering system is a rack-and-pinion type with electric power assistance, offering precise and responsive steering feel.
Market Reception & Comparison
The E 450 4MATIC Coupe was generally well-received by automotive critics, who praised its powerful engine, refined ride, and luxurious interior. It was often compared favorably to its rivals, such as the BMW 4 Series and Audi A5 Coupe. Fuel economy was considered reasonable for a vehicle of its size and performance, with combined fuel consumption figures ranging from 8.6 to 8.8 liters per 100 kilometers (27.4 to 26.7 US mpg). Compared to the E 300, the E 450 offered a significant performance upgrade, but at a higher price point. The E 450 also provided a more balanced driving experience than the more focused AMG models, making it a popular choice for buyers seeking a blend of luxury and performance.
Legacy
The M276 engine family, including the M276.823 found in the E 450, has proven to be relatively reliable, although preventative maintenance is crucial. Common issues include potential oil leaks and occasional problems with the turbochargers. The 9G-TRONIC transmission is also generally reliable, but requires regular fluid changes to ensure smooth operation. In the used car market, the E 450 4MATIC Coupe holds its value well due to its desirable combination of performance, luxury, and all-wheel-drive capability. It remains a compelling option for buyers seeking a sophisticated and capable grand tourer.
