Mercedes-AMG CLS 53 2018 Review: Hybrid Power And Luxury

The 2018 Mercedes-AMG CLS 53 marks a pivotal shift for AMG, introducing electrification to its lineup while preserving the brand’s signature thrill. This four-door coupe combines a sleek ‘Sensual Purity’ design with a sophisticated 3.0-liter inline-six engine augmented by mild-hybrid technology, delivering 429 horsepower and 384 lb-ft of torque. It accelerates from 0-60 mph in about 4.5 seconds, blending everyday refinement with spirited driving dynamics.

Design and Exterior Highlights

The CLS 53 embodies Mercedes’ modern aesthetic with its elongated hood, frameless doors, and fastback roofline that emphasizes elegance over aggression. The ‘predator’ grille stands tall and imposing, flanked by slim LED headlights that pierce the night. Unlike predecessors, this third-generation model ditches excessive creases for smooth, flowing lines that make it appear larger and more predatory from afar.

• Sleek Profile: The cab-forward stance and subtle character lines create a sense of motion even at rest.
• AMG Touches: Quad exhaust tips, larger 19-inch wheels (upgradable to 21s), and a subtle rear diffuser hint at its performance credentials without overwhelming the luxury vibe.
• Aero Efficiency: Active grille shutters and underbody panels optimize airflow for better fuel economy and stability at high speeds.

Critics note the rear can appear bulky from certain angles, but overall, it stands out in a sea of sedans, appealing to those seeking a unique grand tourer.

Powertrain Innovation: The Heart of the CLS 53

At its core is the M256 3.0-liter twin-turbo inline-six, a departure from AMG’s V8 dominance. Paired with an integrated starter-generator (ISG) providing 21 hp and 184 lb-ft boosts, plus a 48-volt mild-hybrid system, it ensures seamless power delivery. An electric auxiliary compressor eliminates turbo lag, spooling instantly for responsive acceleration.

The 4MATIC+ system defaults to rear-biased power (up to 100% rear) but engages front wheels as needed, without a drift mode found in higher AMG models. This setup prioritizes balance over tail-happy antics, making it ideal for varied conditions.

Chassis and Driving Dynamics

Built on the MRA platform shared with the E-Class, the CLS 53 features AMG-tuned air suspension (standard), adaptive dampers, and revised geometry for sharper responses. In Comfort mode, it glides over imperfections, thanks to laminated glass and extensive sound deadening. Switch to Sport+ and it transforms: firmer damping, quicker steering, and aggressive exhaust notes sharpen its edge.

• Handling Prowess: Precise steering with good weight, though some find it slightly light; the car shrinks around the driver on twisty roads.
• Ride Quality: Air springs absorb most bumps, but large expansion joints can thud through.
• Braking: Massive ventilated discs (15.4-inch front) provide confident stopping power, though heavy use reveals fade potential.

Reviewers praise its motorway composure and ability to ‘swoop and dive’ like a fighter jet, offering thrills without sacrificing long-distance comfort.

Interior Luxury and Technology

Step inside, and you’re enveloped in premium materials: Nappa leather, wood veneers, and metal accents. The dual 12.3-inch screens run the MBUX predecessor COMAND system, intuitive yet feature-packed. AMG Performance seats hug firmly with ventilation and massage functions; rear space surprises with a 2.9-meter wheelbase accommodating adults comfortably, despite the coupe roof.

Boot capacity is adequate at 520 liters, expandable by folding seats. Standouts include Burmester audio, wireless charging, and ambient lighting with 64 colors.

Performance in Real-World Scenarios

On open roads, the CLS 53 excels as a cruiser, with effortless overtaking via the ISG’s torque fill. In urban settings, it’s unobtrusive—smooth pullaways and quiet cabin fool you into forgetting its power. Track-like pushes reveal limits: the engine’s smoothness trumps V8 drama, but the EQ Boost delivers addictive surges.

Fuel efficiency impresses at 8.7L/100km combined, a boon for its 4,200-lb weight. The optional Performance exhaust (not always fitted in early tests) adds character, though the inline-six remains more refined than raucous.

Rivals and Market Positioning

The CLS 53 slots between entry-level CLS 450 and the V8-powered CLS 63, targeting buyers wanting AMG flair without extremes. Key competitors:

At around $110,000-$120,000 base, it offers exclusivity and tech edges, though rivals may edge it in outright thrill.

Pros, Cons, and Buying Considerations

• Pros: Innovative hybrid power, supreme refinement, spacious cabin, tech-loaded.
• Cons: Less visceral than V8 AMGs, pricey options, rear visibility hindered by sloping roof.
• Costs: Expect high tire/brake wear; maintenance suits well-heeled owners.

Ideal for executives craving style and subtlety over track weapons.
