During a week-long test drive of the 2019 Mercedes-Benz CLS 450 4Matic, the experience proved to be overwhelmingly positive. This third-generation model showcases a stunning design both inside and out, integrates a wealth of advanced technology, and delivers an exceptional driving experience. While there are minor compromises, particularly concerning rear passenger space, the CLS 450 emerges as a remarkable luxury vehicle, especially for those prioritizing style and sophisticated cruising.
Design and Aesthetics: Prioritizing Style
The most striking feature of the 2019 Mercedes-Benz CLS 450 is undoubtedly its dramatically sloping roofline. This design element, while visually captivating, does come with functional trade-offs. Sharing its platform with the more conventionally styled E-Class, the CLS distinguishes itself with a coupe-like silhouette. However, this design choice impacts rear headroom and the shape of the door openings, which can make entry and exit less convenient for rear passengers. Despite Mercedes-Benz marketing the CLS as a coupe, its four-door configuration naturally leads occupants to expect passenger-friendly practicality, which is somewhat compromised in this model.
Exterior Styling: Mature and Refined
Putting aside the minor practicality concerns, the 2019 CLS 450 is undeniably a visually appealing vehicle. Its design is cleaner and more sophisticated compared to its predecessors, presenting a front fascia that subtly hints at AMG styling influences without being overtly aggressive. If there’s a less compelling aspect of the exterior, it might be the rear. While not unattractive, the rear design appears somewhat understated when juxtaposed with the sharply sculpted front end. Overall, the exterior exudes a mature elegance that aligns with the Mercedes-Benz brand ethos.
Interior Elegance: A Cabin of Premium Materials
Stepping inside the 2019 Mercedes-Benz CLS 450 reveals a cabin that is nothing short of gorgeous. The test vehicle featured a two-tone stitched brown leather interior complemented by open-pore wood trim, creating a warm and luxurious ambiance. Every surface feels premium, with no hint of cheap materials. Even the door pockets are lined with fabric, showcasing attention to detail. The front seats are particularly noteworthy for their deep bolstering and excellent support, making them the most desirable seats in the car – even before considering the heated massage functions.
Enhancing the passenger experience further is the Energizing Comfort system. This feature offers selectable “moods” that orchestrate the climate control, fragrance, ambient lighting, music, and seat massage functions to create a specific atmosphere within the cabin. While some might find it slightly gimmicky, certain pre-programmed settings are genuinely enjoyable and enhance the driving experience. The 64-color ambient lighting system is particularly impressive at night, illuminating a significant portion of the interior. A subtle yet sophisticated touch is the integrated lighting within the air vents, which glows blue when cooling is increased and red when heating is intensified.
Technology and Features: Infotainment and Connectivity
Beyond the ambient features, the 2019 Mercedes-Benz CLS 450 is packed with advanced infotainment and connectivity technology. The test vehicle was equipped with dual 12.3-inch digital displays. The display in front of the driver functions as a configurable gauge cluster with various display themes, while the central screen houses the COMAND infotainment system. While the CLS 450 doesn’t feature the latest MBUX system found in newer Mercedes-Benz models like the A-Class, the COMAND system remains highly capable. Years of refinement have resulted in a system that is responsive and intuitive to operate, whether using the center console controls, steering wheel thumb pads, or voice commands. The COMAND system is feature-rich, offering a premium Burmester audio system with an impressive 25 speakers, navigation, 4G LTE Wi-Fi hotspot, Apple CarPlay, and Android Auto integration.
For device charging and connectivity, the front cabin provides a wireless charging pad and three easily accessible USB ports. Rear passengers are catered to with a single USB jack, a 12-volt outlet, and a two-prong plug located on the back of the center console. In line with other high-end Mercedes-Benz models like the S-Class, the CLS 450 offers a suite of semi-autonomous driving aids, including systems for maintaining lane position in traffic and executing lane changes. Standard and optional safety features include adaptive cruise control, forward collision warning with automatic emergency braking, blind-spot monitoring, and a head-up display.
Performance and Driving Dynamics: Mild Hybrid Efficiency
Perhaps the most technologically sophisticated aspect of the 2019 Mercedes-Benz CLS 450 is its mild hybrid drivetrain. It features a new 3.0-liter inline six-cylinder engine producing 362 horsepower and 369 pound-feet of torque. Mercedes-Benz enhances this engine with a 48-volt alternator and electric motor, contributing an additional 21 horsepower and 184 pound-feet of torque. This electric boost aids initial acceleration and powers auxiliary systems when the car is stationary. Paired with a smooth-shifting nine-speed automatic transmission, this powertrain combination enables the CLS 450 4Matic to accelerate from 0 to 60 mph in just 4.8 seconds. The integration of electric propulsion is seamless, resulting in linear power delivery and nearly imperceptible gear changes.
The mild hybrid system also enhances fuel efficiency and refines the stop-start system. Stop-start systems are often criticized for their abruptness and slow engine restart, but in the CLS 450, the inline-six engine restarts almost instantly and smoothly. This efficiency contributes to the CLS 450 4Matic achieving EPA-estimated fuel economy figures of 23 mpg in the city and 30 mpg on the highway.
In terms of ride comfort and handling, the optional air suspension in the CLS 450 delivers a plush ride in Comfort mode, effectively absorbing road imperfections. This makes it an excellent choice for long-distance driving. Switching to Sport Plus mode sharpens the engine response, firms up the suspension for improved cornering, and the 19-inch Goodyear Eagle F1 Asymmetric 3 tires (245/40 front, 275/35 rear) provide substantial grip. The only minor dynamic drawback is the somewhat numb on-center steering feel, even in Sport mode. While steering response firms up with increased input, initial turn-in could be sharper.
Ideal Configuration and Value
For a personally configured CLS 450, opting for the standard rear-wheel-drive model, starting at $70,195 (including destination charges), would be a sensible choice. Adding the Lunar Blue Metallic paint and the AMG Line package enhances the aesthetics without significantly increasing the price. For interior enhancements, the Premium Package, with its upgraded Burmester sound system and wireless charger, is a worthwhile addition. Further enhancing front seat comfort with massage, rapid heating, and cooling functions adds a touch of luxury. Finally, the Parking Assist Package, including a 360-degree camera and rear cross-traffic alert, adds practical convenience. This configuration brings the total to around $76,875, significantly less than the $93,880 price of the 4Matic test vehicle.
Conclusion: A Style-Focused Luxury Cruiser
The 2019 Mercedes-Benz CLS 450 is a compelling option for buyers who prioritize style and luxurious comfort over outright rear passenger space. For those frequently transporting rear passengers, a standard E-Class might be a more practical choice. However, if rear seat usage is occasional, the CLS 450 offers a unique blend of performance, striking design, and a high-quality, comfortable cabin. While it has four doors, the CLS 450 is best enjoyed as a sophisticated and stylish vehicle for one or two occupants, making a strong statement on the road.
