Mercedes CLS Class Road Trip Review: The Ultimate Drive

As a long-time enthusiast and owner of Mercedes-Benz vehicles, I often get asked about which models truly shine on extended journeys. While many cars can make it from point A to point B, few manage to make the journey as enjoyable and memorable as the Mercedes-Benz CLS Class. It’s not just a car; it’s a statement of intent for the discerning driver who values both form and function on the road. My recent extensive road trip in a CLS reaffirmed my belief that this four-door coupe is a masterclass in automotive engineering designed for the discerning traveler.

The CLS Class has always occupied a unique space in the Mercedes-Benz lineup. Positioned as a four-door coupe, it blends the sleek, athletic silhouette of a coupe with the practicality of a sedan. This distinctive design language not only turns heads but also contributes to its aerodynamic efficiency, a subtle advantage on long highway stretches. Whether you’re cruising through scenic byways or tackling cross-country distances, the CLS aims to provide an experience that is both exhilarating and profoundly relaxing.

Why the CLS Class Excels as a Road Trip Vehicle

The CLS Class is engineered with long-distance comfort and performance as core tenets. It’s not merely about getting there; it’s about enjoying every mile. Several key factors contribute to its superiority as a road trip machine:

Supreme Comfort: The interior is a sanctuary. Plush, supportive seats, advanced climate control, and exceptional noise insulation create an environment where fatigue is minimized, even after hours behind the wheel.
Potent Performance: Whether you choose a gasoline or diesel engine, the CLS provides ample power for effortless overtaking and sustained high-speed cruising. This translates to less strain on the engine and a more relaxed driving experience.
Sophisticated Ride Quality: Mercedes-Benz is renowned for its ability to balance sporty handling with a supple ride. The CLS’s suspension system, often featuring adaptive damping, absorbs road imperfections beautifully, ensuring a smooth journey on various surfaces.
Advanced Technology: From intuitive infotainment systems to cutting-edge driver-assistance features, the CLS is packed with technology designed to enhance safety, convenience, and enjoyment on the road.
Elegant Design: The striking exterior and interior design elements of the CLS contribute to the overall sense of occasion. Arriving at your destination in a CLS feels as special as the journey itself.

My Road Trip Experience: A Deep Dive

To truly assess the CLS Class for a road trip, I recently embarked on a 1,500-mile journey from the rolling hills of the countryside to the bustling heart of a major city and back. My chariot for this adventure was a meticulously maintained CLS 450 4MATIC.

First Impressions: The Launch

Pulling out of the driveway, the CLS immediately asserts its presence. The 3.0-liter inline-six engine, augmented by the EQ Boost mild-hybrid system in the CLS 450, delivers a smooth, immediate surge of power. There’s no lag, no drama – just refined acceleration that effortlessly merges you into traffic. The 4MATIC all-wheel-drive system provides a sense of planted stability, assuring confidence even in less-than-ideal weather conditions.

The Highway Mile-Muncher

Once on the highway, the CLS truly comes into its own. The adaptive cruise control, part of the optional Driving Assistance Package, proved to be an invaluable co-pilot. It maintained a safe distance from the vehicle ahead with remarkable smoothness, significantly reducing driver fatigue. The lane-keeping assist, subtly nudging the car back into its lane, added another layer of security.

The cabin is remarkably quiet. Road noise and wind noise are exceptionally well-managed, allowing for easy conversation or an immersive audiophile experience through the premium sound system. The seats, with their multi-contour adjustment, heating, and ventilation, are supportive and comfortable for extended periods. I particularly appreciated the massage function, which was a welcome relief during longer stretches.

Engine Performance and Fuel Economy

The CLS 450’s powertrain is a near-perfect compromise for a road trip. The 362 horsepower and 369 lb-ft of torque are more than enough for confident overtakes. The 9G-TRONIC automatic transmission shifts imperceptibly, keeping the engine in its sweet spot. While it’s a powerful machine, the mild-hybrid system contributes to impressive fuel economy. On my predominantly highway journey, I averaged around 28 miles per gallon, which is excellent for a vehicle of this class and performance. This means fewer stops at the fuel pump and more time enjoying the drive.

Interior Ambiance and Technology

The interior design of the CLS is a masterclass in modern luxury. The ambient lighting, customizable to myriad colors, creates a sophisticated and inviting atmosphere, especially for nighttime driving. The large MBUX (Mercedes-Benz User Experience) infotainment system is intuitive and responsive, with both touchscreen and touchpad controls. Navigating through music, navigation, and vehicle settings is straightforward. Voice control is also remarkably effective, allowing me to adjust the climate, find points of interest, or change radio stations without taking my hands off the wheel.

The materials used throughout the cabin are of the highest quality – supple leather, genuine wood trim, and precisely finished metal accents. It feels every bit the luxury vehicle Mercedes-Benz promises. Small touches, like the beautifully designed air vents and the tactile quality of the buttons, elevate the everyday driving experience.

Handling and Ride Dynamics

While comfort is paramount, the CLS doesn’t shy away from engaging driving dynamics when the road turns twisty. The optional AIR BODY CONTROL air suspension provides a supple ride that absorbs bumps and undulations with ease. When Sport mode is selected, the ride firms up, and the steering becomes more direct, offering a gratifying connection to the road. The CLS feels balanced and composed through corners, inspiring confidence even at higher speeds on country roads.

Cargo Space and Practicality

For a four-door coupe, the CLS offers surprisingly decent practicality. The 15.7 cubic feet of trunk space is sufficient for a couple of large suitcases and overnight bags. While it might not rival a traditional sedan or SUV, for a weekend getaway or a week-long trip for two, it’s more than adequate. The opening to the trunk is also reasonably wide, making it easy to load and unload luggage.

Key Features Enhancing the Road Trip Experience

The CLS Class is equipped with a suite of features that significantly elevate the road trip experience. These are not just luxuries; they are intelligently integrated systems designed for comfort, safety, and convenience on long journeys.

Which CLS Class is Best for a Road Trip?

The CLS Class is offered in several variants, each with its unique strengths for road trip purposes. The choice often comes down to priorities regarding performance, fuel efficiency, and specific luxury appointments.

CLS 450 4MATIC: This is often considered the sweet spot for a road trip. The inline-six engine with EQ Boost provides a refined balance of power and efficiency. The 4MATIC all-wheel drive adds an extra layer of confidence. It offers a luxurious experience without the extreme performance of AMG models, focusing more on comfort and long-distance cruising.
CLS 53 AMG 4MATIC+: For those who seek a more spirited drive and appreciate AMG’s performance enhancements, the CLS 53 is an excellent choice. It retains much of the comfort and luxury of the standard CLS but adds a significant dose of performance. The distinct AMG driving dynamics and sound are a joy on winding roads, all while still being a capable long-distance cruiser. Fuel economy will be slightly lower than the CLS 450.
CLS Brabus Models (if applicable and within budget): While not standard Mercedes-Benz offerings, Brabus tuning can transform an already exceptional vehicle into something truly extraordinary. If you encounter a tuned CLS, expect enhanced power, bespoke luxury, and unmatched exclusivity for your road trip.

Factors like the specific model year and optional packages can also influence the road trip experience. For instance, models equipped with the advanced Driver Assistance Package and the AIR BODY CONTROL suspension will generally offer a superior ride quality and more relaxed driving dynamics.

Maintaining Your CLS for the Ultimate Road Trip

Before setting off on any significant road trip, ensuring your Mercedes-Benz CLS is in top condition is crucial. A little preventative maintenance can save a lot of headaches and ensure a smooth, enjoyable journey.

Here’s a checklist for preparing your CLS for the open road:

1. Tire Check:
Pressure: Inflate tires to the recommended pressure, usually found on a sticker inside the driver’s doorjamb or in the owner’s manual. Proper inflation is key for fuel economy and tire wear.
Tread Depth: Ensure adequate tread depth for grip, especially if you might encounter inclement weather. The legal minimum tread depth is 2/32nds of an inch (1.6mm), but at least 4/32nds is recommended for safety.
Condition: Inspect for any cuts, bulges, or uneven wear that could indicate a problem.
2. Fluid Levels:
Engine Oil: Check the oil level and condition. If you’re close to your next scheduled oil change, it’s best to get it done before the trip.
Brake Fluid: Ensure the brake fluid level is within the recommended range.
Coolant: Verify the coolant level and its condition. A properly functioning cooling system is vital for preventing overheating.
Washer Fluid: Top up the windshield washer fluid, especially for long drives where bugs can accumulate on the windshield.
3. Brake System Inspection:
Check brake pad thickness and rotor condition. If they are nearing their wear limit, replace them before the trip. A sudden brake failure on a road trip can be catastrophic.
4. Battery Health:
A failing battery can be a major inconvenience. Have it tested to ensure it can handle the demands of the vehicle’s electronics, especially in varying temperatures.
5. Wiper Blades:
Worn wiper blades can seriously impair visibility. Replace them if they streak or chatter.
6. Lights:
Check all exterior lights – headlights, taillights, brake lights, turn signals – to ensure they are all functioning correctly.
7. General Inspection:
Listen for any unusual noises from the engine, suspension, or exhaust.
Check for any warning lights on the dashboard. Address them immediately.

Most of these checks can be done by a DIY enthusiast. However, for critical components like brakes and suspension, it’s always best to have them inspected by a qualified Mercedes-Benz technician at your local dealership or a trusted independent specialist. You can find a guide to Mercedes’ recommended maintenance schedules on the official Mercedes-Benz USA website.

Road Trip Essentials for Your CLS

Beyond the car itself, a few essential items can significantly enhance your road trip experience.

Navigation Device/App: While the CLS has an excellent built-in system, having a backup (like Waze or Google Maps on your phone) can be beneficial, especially in areas with spotty cellular service.
Phone Mount: For easy access to navigation and music control without compromising safety.
Portable Power Bank: To keep your devices charged when not in the car.
First-Aid Kit and Emergency Car Kit: Essential for any unexpected situations. This includes jumper cables, a flashlight, basic tools, and any personal medications.
Comfort Items: Neck pillow, travel blanket, snacks, and water bottle to make the journey more pleasant.
Car Care Kit: A small kit with detailing spray, microfiber cloths, and window cleaner can help keep the CLS looking its best throughout the trip.
