Test of the Mercedes CLA 350 4MATIC: Consumption and Range

With the CLA 350 4MATIC, Mercedes reaches a historic milestone and delivers a product of impressive maturity. By combining a high-performance dual motor architecture, royal comfort worthy of higher segments, and record aerodynamics (Cx 0.21) allowing for nearly 500 km of real-world highway range, the star brand definitively eliminates the fear of running out of charge. Against direct competitors like the Tesla Model 3, BMW i4, or BYD Seal, this CLA immediately establishes itself as the new premium reference for long-distance drivers.

This report details the strengths and specifics of the 350 engine, particularly its dynamic behavior with all-wheel drive, as well as consumption figures under summer conditions. Feel free to refer to it for driving plans or to visualize certain elements discussed in your article.

Sculptural Exterior Look Driven by Design and Cx

Visually, this sedan measuring 4.72 m long, 1.88 m wide, and 1.47 m high successfully manages to dazzle while adhering to strict efficiency requirements. Its sleek and fluid silhouette boasts an exceptional aerodynamic coefficient (Cx) of 0.21. This athletic profile allows it to slice through the air with minimal resistance. Proudly resting on its optional 19-inch wheels, the CLA asserts its premium character, enhanced by the exclusive Alpine Gray color that beautifully highlights the purity of its lines.

Consumption and Range: The Magical Effect of Efficiency

Equipped with an 85 kWh battery, the CLA 350 4MATIC boasts a theoretical range of 750 km according to WLTP standards (notably, the rear-wheel drive CLA 250+ with 272 hp and a 2-speed gearbox can reach up to 790 km!). During our tests conducted at an ideal temperature of 30°C with the air conditioning on (which consumes only about 5% of the energy), the real results were impressive:

• On the highway (at an average of 130 km/h): The consumption is an excellent 17.3 kWh / 100 km, resulting in a range close to 500 km until empty, and a very safe real-world range of 400 km.
• On the road: The appetite drops to 13.5 kWh / 100 km, allowing for 580 km of real-world usage (and up to 630 km until empty).
• Overall average for the trip: On a route composed of 80% highway, the final average stabilized at 16.2 kWh / 100 km.

On the charging side, the architecture can handle a spectacular maximum charging power of 320 kW, charging from 10 to 80% in just 22 minutes, while the regenerative braking system can recover up to 200 kW during deceleration.

Space and Volume: Two Trunks for Twice the Practicality

Thanks to a completely flat floor in the rear, space is abundant. Two adults can easily sit and enjoy the generous space and central armrest, although the middle seat is somewhat compromised. On the loading side, Mercedes perfectly utilizes the electric architecture by offering two trunks:

1. Main rear trunk: Offers a volume of 405 liters, ideal for traditional luggage.
2. Front trunk (Frunk): Provides 101 liters of storage space under the hood. This is the perfect and highly practical spot to store charging cables without dirtying the rest of the car.

Price and Options of Our Test Configuration

Offered at a starting price of €68,300, our test configuration included around €10,000 in options, bringing the final price to nearly €78,300. Here are the details of the equipment present on this model:

• Alpine Gray paint: €1,900 (expensive but stunning).
• Premium Plus Package: Nearly €5,000 (including many cutting-edge technological features).
• 19-inch wheels: €1,150.
• Matte white natural fiber decorative inserts Silent Lines: €350.
• ARTICO / MICROCUT microfiber upholstery in black / pearl white with red stitching: €200.

Conclusion: An Electric Car That is Enjoyable on Long Trips

In conclusion, Mercedes delivers with the CLA 350 4MATIC an electric sedan of incredible technological maturity. Through meticulous work on aerodynamics and the efficiency of its powertrain, the German manufacturer proves that it is possible to combine the performance of all-wheel drive with the comfort of a grand touring vehicle while offering reassuring highway range that eliminates the compromises of electric vehicles during long journeys.
