Powertrain & Engine Architecture
The EQS 450 4MATIC utilizes a dual-motor, all-wheel-drive (AWD) powertrain. Each axle features a permanently excited synchronous motor (PSM), a design favored for its efficiency and power density. The system delivers a combined output of 360 horsepower and 800 Nm (590 lb-ft) of torque. The 125 kWh battery pack, composed of 12 modules, is positioned within the vehicle floor, contributing to a low center of gravity and improved handling. The battery employs advanced thermal management to maintain optimal operating temperatures, crucial for both performance and longevity. Mercedes-Benz’s energy recovery system is highly sophisticated, offering adjustable regenerative braking levels to maximize efficiency. The car uses a single-speed automatic transmission for each axle, typical of electric vehicle setups.
Driving Characteristics
The EQS 450 4MATIC offers a refined and comfortable driving experience. Acceleration from 0-60 mph takes approximately 5.4 seconds, providing ample power for everyday driving and highway merging. While not as aggressively quick as the EQS 580, the 450 delivers smooth and linear power delivery. The air suspension provides a plush ride, effectively isolating passengers from road imperfections. The AWD system ensures confident traction in various weather conditions. The single-speed transmission means there are no gear changes, contributing to the seamless acceleration. Compared to potential internal combustion engine (ICE) alternatives, the instant torque of the electric motors provides a unique and responsive driving feel.
Equipment & Trim Levels
The EQS 450 4MATIC comes standard with a high level of equipment, reflecting its luxury positioning. Standard features include the MBUX Hyperscreen, a massive curved OLED display spanning the dashboard, premium leather upholstery, heated and ventilated front seats, a panoramic sunroof, and a comprehensive suite of driver-assistance systems. Optional extras include rear-axle steering, which enhances maneuverability, augmented reality head-up display, and various interior trim and color options. The interior design emphasizes minimalism and high-tech aesthetics, with a focus on sustainable materials.
Chassis & Braking
The EQS features an independent multi-link suspension at both the front and rear axles, coupled with Mercedes-Benz’s AIRMATIC air suspension system. This combination provides a comfortable ride and excellent handling characteristics. The air suspension automatically adjusts ride height based on speed and driving conditions. Braking duties are handled by ventilated disc brakes on all four wheels. The EQS incorporates advanced braking features such as ABS (Anti-lock Braking System) and regenerative braking, which helps to recapture energy and extend range. The car also features 4-wheel steering (4WS) as an option, improving low-speed maneuverability and high-speed stability.
Market Reception & Comparison
The EQS 450 4MATIC has been generally well-received by automotive critics, praised for its luxurious interior, smooth ride, and advanced technology. Its range of 654-798 km (406-496 miles) on the WLTP cycle is competitive within the luxury EV segment. Compared to the EQS 580, the 450 offers a more accessible price point while still delivering a premium experience. Fuel economy, expressed as MPGe, ranges from 123-100, depending on driving conditions. Reliability data is still emerging, as the model is relatively new, but Mercedes-Benz has a generally good reputation for build quality and durability.
Legacy
The EQS 450 125 kWh 4MATIC represents a key step in Mercedes-Benz’s transition to an all-electric future. Its advanced battery technology, sophisticated powertrain, and luxurious features set a high standard for electric luxury sedans. The long-term reliability of the powertrain remains to be seen, but the use of proven synchronous motor technology and a robust thermal management system suggests a promising outlook. On the used car market, the EQS is expected to hold its value well, particularly as demand for electric vehicles continues to grow. The 2024 facelift further enhances the EQS’s appeal, addressing some initial criticisms and solidifying its position as a leading contender in the luxury EV segment.
