Range figures often spark debate among electric-vehicle shoppers. In the case of the new 2026 Mercedes-Benz CLA with EQ Technology, one independent test produced a result far beyond the official government estimate. Edmunds completed a full-range evaluation and recorded 385 miles on a charge.
Mercedes lists the CLA 350 4MATIC with EQ Technology at 312 miles under EPA certification. Put another way, the difference reached 73 miles, or 23.2 percent. Converted into metric units, those figures equal 620 km and 502 km.
The result becomes even more interesting when energy use enters the discussion. Edmunds measured consumption at 25.7 kilowatt-hours per 100 miles during its evaluation. The EPA figure referenced in the comparison stands at 29 kilowatt-hours. Based on those findings, the publication concluded the CLA 350 4MATIC with EQ Technology performed 12.8 percent better than its advertised efficiency rating.
Getting there involved a procedure quite different from the federal certification process. Edmunds follows a fixed route made up of roughly 60 percent city driving and 40 percent highway driving. Drivers maintain an average pace of about 40 mph, or 64 km/h. Climate-control systems stay active, and vehicle settings remain in their normal operating modes. There is another detail. Participants keep their speed within five mph of posted limits rather than relying on high-speed cruise-control strategies designed around maximum range.
The run does not continue until the battery reaches zero. Edmunds ends testing with approximately 10 miles, or 16 kilometers, still indicated by the vehicle. The published result combines the distance already traveled with the remaining range shown by the car itself.
Federal testing follows a different path. The EPA bases its calculations on five separate driving cycles, a framework dating back to the Richard Nixon era. Results from those cycles pass through weighting formulas intended to approximate real-world energy consumption. A correction factor of roughly 0.70 then enters the equation, accounting for inefficiencies not fully reflected in laboratory conditions. The process tends to generate more conservative range values.
There is one more number worth mentioning. Buyers interested in the CLA 250+ received an even larger figure from Edmunds. During a separate evaluation, the model covered 434 miles, equivalent to 698 kilometers, in a single outing. That placed the single-motor variant 49 miles ahead of its dual-motor sibling.
Taken together, the results suggest the latest CLA with EQ Technology performs well beyond its official EPA range estimate when subjected to Edmunds’ testing method.
