InsideEVs has reported that the 2027 Mercedes CLA 350 4Matic has exceeded expectations in a recent highway range test. The compact electric sedan managed to travel significantly farther than its official EPA rating, highlighting both its efficiency and engineering focus.
Mercedes CLA 350 4Matic Achieves Impressive Real-World Range
The Mercedes-Benz CLA 350 4Matic, the brand’s smallest and most affordable EV in North America, has demonstrated remarkable efficiency in independent testing. In a 70 mph highway range test conducted by Tom Moloughney for the State of Charge YouTube channel, the CLA 350 4Matic covered 385 miles (~620 km) on a single charge, surpassing its EPA-rated range of 312 miles (~502 km) by 73 miles (~118 km).
The test was performed under typical summer conditions on the New Jersey Turnpike, with tire pressures set to Mercedes’ recommendations. Despite challenging road surfaces, the vehicle maintained high efficiency throughout the drive.

Efficiency and Technical Highlights
The CLA 350 4Matic is equipped with an 85-kWh battery pack and features advanced technologies such as silicone carbide inverters and a two-speed gearbox. During the test, the car averaged 4.44 miles per kilowatt-hour, with efficiency remaining consistent across different segments of the drive.
For the first 95 miles (~153 km), the car averaged 4.50 mi/kWh, improving to 4.52 mi/kWh for the next 100 miles (~161 km), then 4.46 mi/kWh for the following 95 miles, and finishing at 4.44 mi/kWh for the last segment.
Competitor Comparison
The Mercedes CLA 350 4Matic competes in the premium compact EV sedan segment, where models like the Tesla Model 3 Long Range and Polestar 2 Long Range Dual Motor are frequently cross-shopped. In Edmunds’ testing, the Tesla Model 3 achieved 4.6 mi/kWh, while the Lucid Air has reached around 5.0 mi/kWh. The CLA 350 4Matic’s efficiency places it among the top performers in its class.
Historical Context
Mercedes-Benz sold 2.4 million vehicles globally in 2024, representing a 4% decrease year-over-year. The introduction of highly efficient EVs like the CLA 350 4Matic may play a role in the brand’s efforts to address changing market demands and improve future sales performance.
Regional Availability
The Mercedes CLA 350 4Matic is currently the smallest and lowest-priced electric vehicle offered by Mercedes-Benz in North America. Its competitive pricing and efficiency make it a notable option for buyers in this region.

Why this matters
The strong real-world performance of the Mercedes CLA 350 4Matic demonstrates the progress being made in EV efficiency and range. Exceeding EPA estimates by a significant margin provides consumers with greater confidence in the practicality of electric vehicles for long-distance travel.
As automakers face increased competition and shifting consumer expectations, delivering vehicles that outperform official ratings can help brands like Mercedes-Benz stand out in a crowded market.
What this means for buyers
For buyers considering a premium electric sedan, the Mercedes CLA 350 4Matic offers a compelling combination of range, efficiency, and advanced technology. Those cross-shopping with models like the Tesla Model 3 Long Range or Polestar 2 Long Range Dual Motor should take note of the CLA’s real-world capabilities.
Potential customers in North America can expect a vehicle that not only meets but exceeds official range estimates, making it a practical choice for both daily commuting and longer journeys.
