The third-generation Mercedes CLS, launched in 2018, pioneered the four-door coupe segment and continues to captivate with its sweeping lines and upscale appeal. This model fuses the visual allure of a coupe with the usability of a saloon, delivering a compelling package for those prioritizing style alongside everyday functionality. Built on a platform shared with larger Mercedes sedans, it promises refined dynamics and cutting-edge powertrains.

Design and Exterior Highlights

The 2018 CLS adopts Mercedes’ modern design ethos, featuring a long hood, frameless doors, and a fastback roofline that accentuates its sporty silhouette. Frontal styling includes bold LED headlights and a prominent grille, echoing cues from the contemporary A-Class while maintaining a distinct premium presence. The bodywork flows seamlessly to the rear, where slim taillights and a subtle diffuser complete the look.

Wheel sizes start at 19 inches across the range, with AMG models offering larger alloys for enhanced stance. Aerodynamic efficiency is prioritized, contributing to stable high-speed cruising. Available in multiple paint finishes, the exterior exudes sophistication suitable for urban or highway environments.

Powertrain Options and Performance

Mercedes positioned the CLS as an upmarket offering by launching exclusively with potent six-cylinder engines. The CLS 350d diesel delivers 282bhp and 600Nm of torque, achieving 0-62mph in 5.5 seconds and a top speed of 155mph, with official economy figures around 48.7mpg. Higher up, the CLS 400d boasts 335bhp and 700Nm, sprinting to 62mph in 5.0 seconds while promising over 50mpg, thanks to its nine-speed automatic and standard 4MATIC all-wheel drive.

Petrol variants like the CLS 450 feature a turbocharged straight-six with EQ Boost mild-hybrid assistance for smoother low-end response. The Mercedes-AMG CLS 53 introduces an electrified inline-six producing ample power, bridging to the more extreme CLS 63 models. All transmissions are smooth-shifting automatics, emphasizing effortless acceleration.

Performance is accessible from low revs, making overtakes stress-free. The 4MATIC system enhances traction in adverse conditions, while air suspension options deliver a plush ride.

Chassis Dynamics and Driving Experience

Behind the wheel, the CLS excels as a grand tourer. Steering is precise yet light, prioritizing comfort over sharp feedback, ideal for long journeys. Suspension tuning absorbs road imperfections, maintaining composure on motorways where cabin noise is minimal.

In corners, the chassis exhibits balanced handling, with all-wheel drive providing confidence. The diesel engines’ torque-rich nature suits relaxed driving, rarely requiring high revs. AMG variants add sharper responses without sacrificing daily usability, creating a versatile performer.

Interior Comfort and Space

The cabin mirrors the opulence of Mercedes’ E- and S-Class models, with dual 12.3-inch digital displays forming a widescreen cockpit. Leather upholstery, wood veneers, and 64-color ambient lighting elevate the ambiance. The steering wheel, borrowed from flagship models, integrates controls intuitively.

  • Spacious front seats with heating, ventilation, and massage functions (optional)
  • Improved five-seat configuration boosts practicality over prior two-plus-two setups
  • Rear headroom compromised by the coupe roofline, better suited for shorter trips
  • Boot capacity adequate for luggage, though not class-leading

Build quality impresses, though some lower plastics feel less premium. Rear space accommodates adults comfortably for mid-range distances.

Technology and Infotainment

Mercedes’ MBUX predecessor infotainment system includes navigation, Apple CarPlay, Android Auto, and a premium Burmester audio setup. Touchpads and voice commands facilitate operation. Standard features encompass adaptive cruise, parking aids, and LED lighting.

Optional packs add blind-spot monitoring, lane-keeping, and surround cameras. The interface, while advanced, lags slightly behind newer Mercedes systems in responsiveness.

Safety and Driver Assistance

Safety is comprehensive, with forward collision warning, automatic emergency braking, and attention assist as standard. Higher trims offer adaptive cruise, active lane change, and evasive steering. Euro NCAP-equivalent testing underscores strong crash protection and active aids.

Equipment Levels and Pricing Context

Entry models feature 19-inch wheels, Agility Control suspension, and keyless entry. Premium packs (~£4,000) include panoramic roofs, enhanced audio, and multicontour seats. In 2018, pricing started around £50,000, positioning it above the E-Class despite similarities.

Ownership costs reflect luxury status: 4-year/50,000-mile warranty, with fuel efficiency offsetting taxes.

  • Cons: Rear headroom limitations, higher price than E-Class, tech not fully modernized
