Mercedes E350 CDI Coupe: 3.0L V6 Review, Specs & MPG

The Mercedes E350 CDI Coupe stands out as a premium grand tourer that combines elegant design, potent diesel power, and superior comfort. This two-door model delivers a compelling package for enthusiasts seeking style without sacrificing practicality or efficiency.

Striking Exterior Design and Aerodynamics

Mercedes crafted the E350 CDI Coupe with a sleek, low-slung profile that exudes sophistication and presence on the road. Its elongated hood and frameless doors contribute to a dynamic silhouette, enhanced by a coefficient of drag as low as 0.24, making it one of the most aerodynamic production cars available. This not only boosts fuel efficiency but also ensures a serene cruising experience by minimizing wind resistance.

The coupe’s dimensions—approximately 4.7 meters long with a 2.76-meter wheelbase—provide a balanced stance that’s imposing yet agile. Optional features like a panoramic sunroof further amplify the open-air feel when paired with retractable rear windows, mimicking a convertible sensation without the compromises.

Opulent Interior Craftsmanship

Step inside, and the cabin impresses with high-quality materials and thoughtful ergonomics. The minimalist dashboard offers excellent visibility thanks to slim pillars, while the steering-column-mounted gear selector frees up console space for added luxury. Multicontour seats, often equipped with extended leather packages, wrap occupants in supportive comfort, ideal for extended journeys.

Mercedes improved the infotainment system for intuitive navigation, a welcome upgrade that enhances usability. Four seats accommodate passengers adequately, and the 400-liter boot offers reasonable cargo space for a coupe. Ambient lighting and premium touches create an upscale environment rivaling larger sedans.

Powerful V6 Diesel Engine and Transmission

At the heart lies a 3.0-liter V6 turbodiesel producing 231-258 horsepower and up to 620 Nm of torque from 1,600 rpm, depending on the variant. This delivers brisk acceleration—0-62 mph in 6.2-6.7 seconds—and a top speed electronically limited to 155 mph.

The seven-speed automatic transmission shifts seamlessly, with paddle shifters and manual mode for driver engagement. Power delivery is smooth and relentless, excelling in mid-range overtakes on highways. Refinement is key: the engine idles almost silently, only revealing its diesel nature under hard acceleration.

Driving Dynamics: Comfort and Agility Balanced

The E350 CDI Coupe prioritizes grand touring prowess over outright sportiness. Its shorter wheelbase compared to the sedan enhances turn-in responsiveness, while parametric steering provides precise feedback. Body control is impressive in dry conditions, with sharp handling and minimal roll through bends.

Standard or optional air suspension (including Dynamic Handling Package) absorbs bumps effectively at speed, though it can feel unsettled over sharp potholes. The Sport mode firms up the ride, quickens throttle response, and sharpens shifts for spirited drives. Grip from wide tires remains strong, bolstered by optional 4MATIC all-wheel drive in later models.

On motorways, wind and road noise are hushed, creating a library-quiet cabin. The soft setup rewards relaxed cruising, making it an ideal long-distance companion.

Fuel Efficiency and Running Costs

Despite its performance, the coupe achieves combined economy of 41.5 mpg (UK) or around 5.1-6 l/100 km, with CO2 emissions at 134-179 g/km. Real-world tests show nearly 40 mpg on highways and 28-30 mpg in mixed urban driving. A 66-liter tank supports extended ranges.

Pricing started around £36,630 in the UK or €53,550 in Germany, positioning it as a premium choice. Insurance groups hover around 17, reflecting its manageable power.

Safety and Technology Features

Mercedes equips the E350 CDI with advanced safety tech, including multiple airbags, stability control, and optional systems like adaptive cruise. The rigid chassis and low drag contribute to inherent stability. Infotainment includes navigation, Bluetooth, and upgraded menus for ease of use.

• Key Tech: Panoramic sunroof, paddle shifters, multicontour seats.

Who Is It For?

This coupe suits executives and couples desiring a stylish, comfortable cruiser for highways and weekends. It’s less ideal for track enthusiasts seeking razor-sharp dynamics, but excels as a refined daily driver with diesel economy.
