Mercedes CLS 250 CDI Review: 53 MPG Diesel Luxury

The Mercedes CLS 250 CDI redefines the four-door coupe segment by combining striking design, advanced diesel power, and exceptional refinement. Powered by a 2.1-liter twin-turbo diesel engine delivering 201 bhp and 500 Nm of torque, this model offers brisk acceleration, motorway prowess, and impressive fuel economy figures around 53 mpg combined.

Design and Exterior Appeal

The CLS 250 CDI boasts a sleek, aerodynamic profile that turns heads with its elongated hood, frameless doors, and sloping roofline. Available in finishes like dark metallic silver, it exudes sophistication while maintaining practicality for four passengers. Low-profile 19-inch wheels wrapped in high-grip tires enhance its sporty stance without compromising ride quality.

• Sweeping coupe-like silhouette with four doors for accessibility.
• Aerodynamic shaping contributes to efficient fuel use and stable high-speed performance.
• LED lighting and chrome accents elevate premium presence.

Engine Performance and Drivetrain

At the heart lies Mercedes’ renowned 2.1-liter four-cylinder twin-turbo diesel, producing 201 bhp at 3800 rpm and a peak 500 Nm torque from just 1600 rpm. This setup propels the CLS from 0-62 mph in 7.5-7.8 seconds, with a top speed around 150 mph, blending urgency with relaxation.

Paired with a smooth seven-speed G-Tronic Plus automatic transmission featuring paddle shifters and column-mounted selector, gear changes are seamless. The gearbox’s re-engineering for the four-cylinder ensures effortless overtaking and motorway cruising, with torque available instantly for confident surges.

Handling and Ride Dynamics

Equipped with comfort-oriented suspension—either standard setup or optional AIRMATIC air suspension—the CLS 250 CDI delivers a planted feel at speed while absorbing UK roads’ imperfections. Low-speed fidget is minimal, giving way to composure on faster routes, with crisp steering and excellent grip from ContiSportContact tires.

It’s not a pure sports car but handles its weight adeptly in corners, offering engaging drive modes via paddles for sportier shifts. Motorway stability shines, with cruise control and speed limiters enhancing long-haul ease.

Interior Comfort and Technology

Inside, full leather trims a spacious cabin with supportive seats that cradle occupants during spirited drives. Dual-zone climate control, Bluetooth audio streaming, built-in navigation, and front/rear parking sensors come standard, creating a high-tech haven.

Rear space accommodates adults comfortably, with individual seats in some configurations adding luxury. Instruments are clear, switchgear premium, and noise insulation exemplary—making the diesel’s hum barely noticeable.

• Leather-upholstered seats with excellent support.
• Intuitive infotainment including nav and Bluetooth.
• Quiet cabin ideal for relaxed cruising.

Fuel Efficiency and Running Costs

BlueEFFICIENCY tech, including stop-start, yields real-world economy near official 53.3-54.3 mpg figures, with CO2 at 135-139 g/km for favorable company car tax (around 22% BIK). At launch, it undercut pricier siblings like the 350 CDI by thousands, balancing luxury with frugality.

Maintenance benefits from Mercedes’ diesel reliability, with MOT validity extending for low-mileage examples.

Practicality: Boot Space and Versatility

Coupe styling doesn’t hinder usability; the sedan version offers a practical boot, while Shooting Brake variants expand to 560 liters (1550 with seats folded) for longer loads. Rear seats fold flat for versatility, suiting executive needs.

Safety and Reliability

Mercedes’ engineering ensures top safety with multiple airbags, stability systems, and robust build. The diesel powertrain proves durable, as seen in low-mileage cars with full service history. Regular updates keep it relevant, though control layouts may require adaptation.
