Mercedes-Benz CLS-Class (2018-present) Pros and Cons

Pros	Cons
Eye-catching looks, inside and out	Compromised rear headroom
Comfortable and confident drive	Premium price tag
The AMG version is hugely quick	Porsche Panamera is more exciting to drive

Quick Summary

The Mercedes-Benz CLS-Class (2018-present) is a stylish four-door coupé that combines luxury with sporty elegance. This generation offers a beautifully crafted interior with mood lighting, highly adjustable front seats, and an intuitive infotainment system. The sweeping roofline sacrifices some rear headroom for taller adults, but provides ample legroom and storage space for most occupants. The traditional saloon-style boot is spacious, though not as convenient as hatchback rivals for larger items.

Engine options include two diesel variants (CLS300d and CLS400d with 4Matic all-wheel drive) and two petrol models (rear-wheel drive 350 and all-wheel drive 450), all featuring mild-hybrid EQ Boost technology. The high-performance CLS53 AMG delivers 429 horsepower and exceptional performance. Expect fuel economy in the high-30s to low-40s for diesels and high-20s to mid-30s for petrols. As a premium car, running costs are substantial, but strong residual values and generous standard equipment across both AMG Line and AMG Line Premium Plus trims help offset expenses. Service intervals occur every 12 months or 10,000 miles, with optional ServiceCare plans available from around £40 monthly.

Best for: Luxury car buyers seeking distinctive styling, those prioritising comfort and technology, and drivers wanting an AMG performance option without sacrificing practicality.

Not ideal for: Taller rear passengers, budget-conscious buyers, or those seeking maximum boot accessibility or outright driving excitement.


Comparison vs Key Rivals



The Verdict

You should buy the CLS if: You prioritise distinctive styling and luxury, seek a comfortable and confident drive, or want an AMG performance variant without compromising practicality.

Consider alternatives if: You need maximum rear headroom, are budget-conscious, require easy boot access, or seek the most exciting driving experience available.

Competitive Position: The Mercedes-Benz CLS-Class (2018-present) is a compelling choice in the luxury four-door coupé segment, offering striking design, refined comfort, and strong residual values. Whilst the Porsche Panamera delivers more thrilling performance and the Audi A7 Sportback provides a slightly more impressive interior, the CLS strikes an excellent balance between style, technology, and driving dynamics. The BMW 6 Series Gran Turismo offers hatchback practicality, but the CLS's sleeker silhouette and confident handling make it the standout choice for those seeking luxury with genuine visual impact.
