The 2027 Mercedes-Benz GLC 400 4Matic Electric has delivered an impressive real-world range result, traveling 392 miles on a full charge during Edmunds’ EV Range Test. That is 61 miles farther than its EPA-estimated range of 331 miles, an 18.4% improvement that highlights the electric luxury SUV’s potential to exceed its official efficiency figures under real-world driving conditions.
The test results also showed that the GLC Electric consumed less energy per 100 miles than the EPA estimates. Combined with its 483-horsepower powertrain and fast-charging capability, the results give Mercedes-Benz an encouraging early performance benchmark for its new electric SUV.
Mercedes-Benz GLC Electric Exceeds Its EPA Range Estimate
The 2027 Mercedes-Benz GLC 400 4Matic Electric traveled 392 miles on a full battery charge in Edmunds’ EV Range Test, surpassing its official EPA range estimate by 61 miles. Its measured range was 18.4% higher than the 331 miles listed in the EPA estimate.
Energy consumption was another strong point. The EPA estimates that the GLC 400 uses 33 kilowatt-hours (kWh) of electricity per 100 miles, while Edmunds measured consumption of just 28.4 kWh per 100 miles. That amounts to roughly 14% less energy use than the official estimate suggests.
The results indicate that the electric SUV can deliver better range and efficiency than its EPA figures might suggest, although actual performance will depend on driving conditions and individual driving habits.
How Edmunds Conducts Its EV Range Test
Edmunds uses a mixed driving route designed to incorporate both urban and highway conditions. The test consists of 60% city driving and 40% highway driving, with an average speed of 40 mph.
Vehicles are kept within 5 mph of posted speed limits, and the climate control is set to 72 degrees. This approach differs from testing conducted exclusively on highways at a steady speed, providing a different measure of how far an electric vehicle can travel under mixed driving conditions.
Even with a consistent testing procedure, real-world range can vary depending on weather, speed, terrain and driving style. Individual owners may therefore achieve different results from those recorded during Edmunds’ test.
How the GLC Electric Compares With Other Luxury SUVs
The Mercedes-Benz GLC Electric’s 392-mile range placed it ahead of several other electric luxury SUVs tested by Edmunds. The 2027 Audi Q6 E-Tron Prestige covered 337 miles, while the 2025 Cadillac Optiq recorded 339 miles.
The 2024 Porsche Macan 4 Electric reached 352 miles in testing, finishing 40 miles behind the Mercedes-Benz. The comparisons put the GLC 400 4Matic Electric ahead of all three vehicles in the reported range results.
These figures reflect Edmunds’ test results for the specific models listed, rather than their official EPA range estimates.
Battery, Power and Charging Specifications
The 2027 Mercedes-Benz GLC 400 4Matic Electric pairs a 94-kWh usable battery with two electric motors that produce a combined 483 horsepower and 590 lb-ft of torque.
The SUV also supports DC fast charging at rates of up to 330 kW. Mercedes-Benz estimates that charging from 10% to 80% takes approximately 22 minutes under ideal conditions.
These specifications combine substantial power output with a large usable battery and high peak charging capability. The Edmunds range result adds another encouraging data point for the electric SUV, although it does not establish how consistently owners will achieve similar mileage in everyday use.
What the Range Test Means for the Mercedes-Benz GLC Electric
The 2027 Mercedes-Benz GLC 400 4Matic Electric traveled 392 miles in Edmunds’ EV Range Test, exceeding its EPA-estimated range by 61 miles while using less energy per 100 miles than officially estimated.
Although real-world results will vary with driving conditions, the test gives Mercedes-Benz’s new electric luxury SUV a strong showing against its stated range figure and the competing models included in Edmunds’ comparison.
