Ever looked at a car and thought, “That’s exactly what I want—power, poise, and polish”? That’s the Mercedes CLS 400 d 4MATIC in a nutshell. This four-door coupe blends the sleek lines of a GT with the muscle of a diesel powerhouse.
It’s a statement vehicle that manages to feel elegant, fast, and thoroughly modern, all at once. Let’s unpack why this car is turning heads and winning hearts across the luxury diesel segment.
Overview Of The Mercedes CLS 400 D 4MATIC
The CLS 400d 4MATIC is part of the Mercedes-Benz CLS Class, designed for those who want style without sacrificing performance. As a 4MATIC model, it comes standard with all-wheel drive, delivering better grip and confidence on the road.
Positioned between the lesser CLS 350d and high-end AMG versions, the 400d hits a sweet spot. With a 2.9-litre six-cylinder diesel engine under the hood, it offers impressive torque and solid refinement. This isn’t just a luxury diesel—it’s a true CLS Coupe with the performance to match.
Key Features And Specifications
The standout numbers? How about 700 Nm of torque, a top speed of 155 mph, and 0-60 in under 5 seconds? Now pair that with 64 colours of ambient lighting, dual digital screens, leather upholstery, and those signature 19 inch wheels.
Other highlights include:
- Fuel tank capacity: Just right for long hauls
- Fuel type: Diesel, of course
- Transmission: 9-speed automatic for seamless shifting
- Advanced instrument binnacle dials for that futuristic vibe
It’s the kind of car that feels just as good pulling up to a five-star hotel as it does eating up highway miles.
Design And Aesthetics
You can thank Chief Designer Gorden Wagener for the signature CLS styling. The long bonnet, coupe-like roofline, and frameless doors are part of what makes the CLS look so different from other cars on the road.
There’s elegance in every curve, with bold mirrors, sculpted flanks, and that wide, low stance. From the front grille to the flowing rear end, it feels more Mercedes-AMG GT than mid-level saloon.
This is a car that commands attention—quietly.
Interior Comfort And Technology
Step inside and you’re wrapped in superb refinement. The cabin’s design is both functional and indulgent, with fine materials and tactile surfaces throughout.
Features you’ll love:
- 64-colour ambient lighting that sets any mood
- Dual screens blending infotainment with the instrument binnacle dials
- Touchpad controls and voice recognition
There’s proper rear seat space, despite the coupe shape—ideal for grown-up passengers on long trips.
Performance And Driving Experience
This car isn’t just about cruising—it’s built to move. The 2.9 litre inline-six diesel engine is both quiet and potent. The 9 speed automatic transmission handles shifts like melted butter.
There’s enough power for overtaking with ease, yet the ride stays composed thanks to adaptive suspension. Whether you’re cornering on a winding road or eating up miles on the motorway, the CLS delivers.
Engine And Transmission: Power And Efficiency
Under the bonnet lies the heart of this beast: a 2.9L turbocharged diesel that churns out 340 hp and 700 Nm of torque. That’s figures you’d expect in something flashier—like a Porsche Panamera.
But here’s the kicker: the fuel efficiency is surprisingly decent. Thanks to the 4MATIC variant, traction is never an issue. And the transmission keeps things smooth, even during sudden bursts of speed.
This is one of those comparatively rare cars that can both sprint and sip.
Ride And Handling Dynamics
Comfort meets control in the CLS 400 d. On smooth tarmac, it glides. On twisty backroads, it grips. The ride and handling dynamics are tuned for both confidence and composure.
With 4MATIC all-wheel drive, you’re grounded. The steering is sharp without being twitchy, and body roll is minimal thanks to a well-sorted chassis. It’s a car that invites spirited driving without ever feeling overworked.
0-60mph: Acceleration Capabilities
For a diesel? It’s quick. The CLS 400 d clocks 0-60 mph in just under 5 seconds. That’s quicker than some petrol-powered rivals in the segment.
It’s the torque that makes the difference—700 Nm ensures you feel a solid push whenever you put your foot down. This is the kind of car that makes highway merging feel like a game.
Technical Highlights
Let’s get nerdy for a second. Here are a few of the key technical standouts:
- Brake fluid monitoring and advanced braking systems
- Intelligent fuel filters that help with longevity
- Aero-tuned body for better efficiency and high-speed stability
- Active suspension settings to tweak your ride
This isn’t just a test car—it’s a finely tuned machine.
Advanced Safety Features
Mercedes never skimps on safety, and the CLS is no exception. From adaptive cruise control to auto emergency braking, it’s all here.
Other highlights include:
- Blind spot monitoring
- Lane-keeping assist
- Cross-traffic alert
And of course, all wrapped up in a sturdy, well-engineered chassis. It’s peace of mind at 155 mph.
Innovative Driver Assistance Systems
Whether it’s traffic jams or tight parking spots, the CLS helps out:
- Semi-autonomous driving at low speeds
- Park assist with 360-degree cameras
- Automatic lane centering
These innovative driver assistance systems mean fewer “oh no” moments behind the wheel.
Infotainment And Connectivity
You get everything you expect from a modern Mercedes—and more:
- Touchscreen infotainment with full Apple CarPlay and Android Auto
- Live traffic updates
- Wireless phone charging and multiple USB-C ports
It’s intuitive, fast, and makes even short drives more enjoyable.
Market Position And Competition
The CLS 400d sits in a very specific space. It’s for drivers who want something more exclusive than an E-Class, but don’t need a full-blown AMG monster.
Its main rivals? The Audi A7 Sportback, Land Rover Velar, and the Porsche Panamera in base trim. But none quite match the CLS’s blend of diesel power and coupe flair.
Price Comparison With Rivals
The CLS 400 d isn’t cheap—but it’s not outrageous either. Priced just under high-spec rivals, it offers strong value for the segment.
It undercuts the Panamera, edges out the Velar on interior quality, and beats the A7 on standard features. For the money, you’re getting serious Mercedes-Benz pedigree.

- BMW 8 Series Gran Coupe
