Powertrain & Engine Architecture
The EQS 450+ is powered by a single rear-mounted electric motor, designated EM0027, producing 360 horsepower and 568 Nm (418.94 lb.-ft.) of torque. The powertrain utilizes a synchronous electric motor, known for its efficiency and smooth power delivery. The 120 kWh battery pack, positioned under the vehicle floor, provides a usable capacity of 108.4 kWh. This battery operates at 396 volts and employs lithium-ion technology. Mercedes-Benz’s energy recovery system allows for substantial regenerative braking, capturing kinetic energy during deceleration and converting it back into electricity, extending the vehicle’s range. The single-speed automatic transmission is a standard feature, providing seamless acceleration.
Driving Characteristics
The rear-wheel-drive configuration of the EQS 450+ delivers a comfortable and refined driving experience. Acceleration from 0 to 60 mph takes approximately 6.4 seconds. While not as quick as the dual-motor EQS 580 4MATIC, the 450+ offers ample power for everyday driving and highway merging. The single-speed transmission provides linear acceleration, and the electric motor delivers instant torque. The low center of gravity, thanks to the battery pack’s placement, contributes to stable handling. The air suspension, standard on the EQS SUV, further enhances ride comfort by absorbing road imperfections. Compared to potential future AMG-tuned versions, the 450+ prioritizes efficiency and smoothness over outright performance.
Equipment & Trim Levels
The EQS 450+ came standard with a comprehensive suite of features, reflecting its luxury positioning. Interior appointments included premium synthetic leather upholstery, heated and ventilated front seats, and a panoramic sunroof. The MBUX Hyperscreen, a massive 56-inch curved OLED display spanning the dashboard, was a prominent feature, integrating the instrument cluster, infotainment system, and passenger display. Standard safety features included adaptive cruise control, lane keeping assist, automatic emergency braking, and a 360-degree camera system. Optional extras included genuine leather upholstery, massaging seats, a Burmester surround sound system, and rear-axle steering for improved maneuverability.
Chassis & Braking
The EQS SUV utilizes an independent multi-link suspension system at both the front and rear axles, enhanced by air suspension for a smooth ride. The air suspension automatically adjusts ride height based on driving conditions and speed. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The EQS SUV also features 4-wheel steering (4WS), which allows the rear wheels to turn independently, improving agility at low speeds and stability at high speeds.
Market Reception & Comparison
The EQS 450+ was generally well-received by automotive critics, praised for its luxurious interior, smooth ride, and long range. However, some reviewers noted that the base model’s acceleration was not as exhilarating as that of its more powerful siblings. Fuel economy, measured in MPGe, ranged from 113 to 91, depending on driving conditions. Compared to the EQS 580 4MATIC, the 450+ offered a more affordable entry point into the EQS SUV lineup, sacrificing some performance for increased efficiency and a lower price tag. The 450+ also provided a more accessible option than the higher-trim levels, appealing to buyers prioritizing comfort and range over outright speed.
Legacy
The Mercedes-Benz EQS SUV, including the 450+ variant, represents a significant step forward in the brand’s electric vehicle strategy. The powertrain, while relatively new, has demonstrated good reliability in early reports. The EQS SUV’s advanced technology, luxurious interior, and long range have established it as a benchmark in the luxury electric SUV segment. On the used car market, the EQS 450+ is expected to hold its value well, appealing to buyers seeking a premium electric SUV with a proven track record. The vehicle’s sophisticated battery management system and durable electric motor contribute to its long-term reliability and appeal.
