Powertrain & Engine Architecture
The E 450 4MATIC is powered by the M 256.830 3.0-liter inline-six cylinder engine, featuring a twin-scroll turbocharger and direct fuel injection. This engine produces 381 horsepower at 5800-6100 rpm and 500 Nm (368.78 lb.-ft.) of torque between 1800-5000 rpm. The engine incorporates Mercedes-Benz’s CAMTRONIC variable valve timing system for optimized efficiency and performance. The ‘48V’ mild hybrid system adds a 23 hp electric motor integrated into the powertrain, providing a boost during acceleration and enabling smoother start/stop functionality. The 9G-TRONIC nine-speed automatic transmission is standard, delivering quick and seamless gear changes. This transmission is specifically tuned to work in conjunction with the mild hybrid system, optimizing power delivery and fuel economy.
Driving Characteristics
The E 450 4MATIC offers a compelling blend of performance and comfort. The mild hybrid system provides immediate torque, resulting in brisk acceleration – 0 to 60 mph in approximately 4.5 seconds. The 9G-TRONIC transmission’s closely spaced gear ratios keep the engine in its optimal power band, providing responsive acceleration in various driving situations. Compared to lower-powered E-Class variants, the E 450 delivers a noticeably more engaging driving experience. While not as overtly sporty as the AMG models, it provides ample power for confident overtaking and highway cruising. The 4MATIC all-wheel-drive system ensures excellent traction and stability in all weather conditions.
Equipment & Trim Levels
The E 450 4MATIC typically comes well-equipped as standard. Features include Mercedes-Benz User Experience (MBUX) infotainment system with a large touchscreen display, premium upholstery (often leather), heated front seats, a panoramic sunroof, and a comprehensive suite of driver-assistance systems. Optional extras include advanced driver-assistance packages, upgraded audio systems (Burmester), and various interior trim options. The interior design emphasizes luxury and technology, with high-quality materials and a modern aesthetic.
Chassis & Braking
The S214 E-Class utilizes a sophisticated chassis design featuring a four-link front suspension and a multi-link rear suspension. The E 450 4MATIC often includes air suspension on the rear axle, providing a comfortable ride and the ability to adjust ride height. Ventilated disc brakes are standard on all four wheels, providing ample stopping power. The electronic stability program (ESP) and anti-lock braking system (ABS) are standard safety features.
Market Reception & Comparison
The E 450 4MATIC has been generally well-received by automotive critics, praised for its refined driving experience, luxurious interior, and advanced technology. Compared to the E 350 models, the E 450 offers a significant performance upgrade. While the E 350 prioritizes fuel efficiency, the E 450 caters to drivers who desire more power and a more engaging driving experience. Fuel economy is respectable for a vehicle of this size and performance, with combined WLTP figures ranging from 7.9 to 8.8 l/100 km.
Legacy
The M 256 engine family, including the M 256.830 found in the E 450, is expected to be a reliable and durable powertrain. Early reports suggest good long-term reliability, although the long-term effects of the mild hybrid system are still being evaluated. On the used car market, the S214 E 450 4MATIC is expected to hold its value well due to its combination of luxury, performance, and technology. The integration of mild hybrid technology positions it as a forward-looking option in the premium estate segment.
