Powertrain & Engine Architecture
The EQS 450+ utilizes a single rear-mounted electric motor producing 360 horsepower and 568 Nm (418.94 lb-ft) of torque. This motor is a synchronous design, known for its efficiency and smooth power delivery. Power is drawn from a 120 kWh lithium-ion battery pack, providing a usable capacity of 108.4 kWh. The battery is positioned low in the vehicle floor, contributing to a low center of gravity and improved handling. The EQS employs a single-speed automatic transmission, typical of electric vehicles, simplifying the drivetrain and maximizing efficiency. The car supports fast DC charging, allowing for significant range replenishment in relatively short periods. The battery management system is sophisticated, incorporating thermal management to maintain optimal battery temperature for performance and longevity.
Driving Characteristics
The EQS 450+ delivers a refined and comfortable driving experience. Acceleration from 0-60 mph takes approximately 5.8 seconds, which is respectable but noticeably slower than the dual-motor EQS 580. The single-motor configuration prioritizes efficiency, resulting in a longer driving range. The single-speed transmission provides seamless acceleration, and the rear-wheel drive layout offers a balanced feel. The air suspension contributes to a smooth ride, effectively absorbing road imperfections. While not a performance-focused variant, the EQS 450+ provides ample power for everyday driving and highway cruising. The steering is precise and well-weighted, and the four-wheel steering system enhances maneuverability at low speeds and stability at higher speeds.
Equipment & Trim Levels
The EQS 450+ typically came standard with a high level of equipment, reflecting its luxury positioning. This included features such as the MBUX Hyperscreen – a massive curved OLED display spanning the dashboard, premium upholstery (often leather or synthetic leather alternatives), advanced driver-assistance systems (including adaptive cruise control, lane keeping assist, and automatic emergency braking), and a premium sound system. Optional extras included massaging seats, augmented reality head-up display, and various interior trim packages. Trim levels within the 450+ variant often differed based on package selections, allowing buyers to customize their vehicle to their preferences.
Chassis & Braking
The EQS 450+ features an independent multi-link suspension at both the front and rear, coupled with air suspension for a comfortable ride. Ventilated disc brakes are used on all four wheels, providing ample stopping power. The car is equipped with ABS (Anti-lock Braking System) and electronic stability control. The rear-wheel drive configuration contributes to a balanced chassis, and the low center of gravity enhances handling. The standard fitment of four-wheel steering further improves agility and stability.
Market Reception & Comparison
The EQS 450+ was generally well-received by critics, who praised its luxurious interior, comfortable ride, and long driving range. Compared to the EQS 580, the 450+ offered a more affordable entry point into the EQS lineup, albeit with slightly reduced performance. Its fuel economy (measured in MPGe) was competitive with other luxury electric vehicles. Reliability reports have been generally positive, although, as with any new technology, some early adopters experienced minor software glitches. Compared to other electric liftbacks in its class, the EQS 450+ stood out for its opulent interior and advanced technology.
Legacy
The EQS 450+ 120 kWh represents a pivotal model in Mercedes-Benz’s transition to electric mobility. The powertrain, while not the highest-performance offering in the EQS range, has proven to be reliable and efficient. On the used car market, these models hold their value relatively well, reflecting the desirability of the EQS brand and the long-term benefits of electric vehicle ownership. The EQS platform itself has set a new benchmark for luxury electric vehicles, influencing the design and technology of subsequent electric models from Mercedes-Benz and its competitors.
