Comprehensive Buyer’s Guide for the Mercedes-Benz AMG CLS 53

Over three generations, its sleek appearance and dependable performance have remained constant. For prospective buyers, understanding the reliability and features of the AMG CLS 53 is essential. Keep reading to discover what makes this model a compelling choice.

Engine, Performance, and Transmission

The AMG CLS 53 features a 3.0-liter inline-six engine with both turbocharging and an electric supercharger. Paired with a nine-speed automatic transmission and all-wheel drive, it also incorporates a 48-volt hybrid system called EQ Boost.

The engine produces 384 lb-ft of torque and 429 horsepower, complemented by EQ Boost, which provides an additional 184 lb-ft torque and 21 horsepower. The CLS 53 can accelerate from 0 to 60 mph in just 4.0 seconds and reaches 111 mph in about 12.5 seconds. Its turbocharged inline-six engine offers eager revs, while the nine-speed transmission ensures quick shifts and smooth performance.

The vehicle comes standard with adaptive dampers and air suspension, offering a balanced ride and confident handling on various road surfaces. Despite this, the CLS 53 may feel somewhat fragile over rough terrains and can lose stability over bumps. The electrically assisted steering provides direct, responsive feedback, enhancing driving enjoyment.

Fuel Efficiency and Real-World Economy

EPA estimates suggest the CLS 53 achieves approximately 26 mpg on highways and 21 mpg in city driving. However, real-world tests reveal it's often more efficient, with reports of up to 30 mpg during 75-mph highway runs.

Interior, Cargo Space, and Comfort

Known for luxurious interiors, Mercedes combines classic elegance with cutting-edge technology in the AMG CLS 53. All major displays are digital, including the instrument cluster, creating a modern yet warm atmosphere. Despite its sporty coupe design, the rear seats are spacious with a 40/20/40 split folding feature, resembling a sedan's comfort. The sloped roofline reduces rear headroom, and the trunk offers about 12 cubic feet of cargo space.

Infotainment and Connectivity

The car features the Mercedes-Benz User Experience (MBUX) system, offering intuitive controls via touchscreens, touchpads, and steering wheel controls. It supports Apple CarPlay and Android Auto, includes three USB ports, and offers integrated navigation for a seamless connect and drive experience.

Safety and Driver Assistance Features

Standard safety tech includes blind-spot monitoring and automatic emergency braking. Additional features encompass adaptive cruise control with stop-and-go function, automatic high-beam headlights, lane-departure warning, and lane-keeping assist—all designed to enhance driver confidence and safety.
