The new 2027 Mercedes-Benz GLC 400 4Matic EV has an EPA-estimated range of up to 331 miles, but in the real world, it will probably go even further.
Mercedes GLC 400 EV tops EPA range in real-world test
Electric vehicles are becoming more efficient thanks to advances in batteries, drive units and more, allowing for longer driving ranges and faster charging.
The new 2027 Mercedes-Benz GLC 400 4Matic EV has an EPA-estimated range of up to 331 miles, which is more than enough for at least a few days of driving on average.
In everyday driving conditions, it can drive much further than its official figures suggest. During Edmunds In real-world range testing, the GLC 400 EV traveled 392 miles, or 18% more than its EPA estimate.
An additional 61 miles of range is huge. You could add another two, three, or even more days of travel between charges.
The electric GLC was also more efficient, consuming just 28.4 kWh per 100 miles, about 14% less than the EPA’s official 33 kWh per 100 miles.
Mercedes’ new GLC outperformed most of its competitors in the real-world range test. The 2027 Volvo EX60 P10 AWD traveled 352 miles, the 2025 Cadillac Optiq covered 339 miles, and the 2027 Audi Q6 E-Tron Prestige covered 337 miles.
The Edmunds Real-World Range Test is designed to provide a more accurate estimate of an electric vehicle’s range under everyday driving conditions.
It consists of 60% city driving and 40% highway driving with an average speed of 40 mph. The vehicle is kept within 5 mph of the posted speed limit and the climate control is set to automatic at 72 degrees.
While charging speeds were not tested, the GLC 400’s 94 kWh battery supports DC fast charging up to 330 kW. Mercedes says it takes about 22 minutes to charge from 10% to 80%.
One thing is certain: electric cars are rapidly becoming more efficient with faster charging and longer ranges.
The number of electric cars offering 300 miles or more of EPA-estimated range has increased from just one model in 2016 (the Tesla Model S 90D) to around 60 by the end of 2026.
Several new 2027 models now approach 400 miles of EPA range on a single charge. A recent BMW Group study found that Americans want more autonomy than they really need.
The study found that 73% say 75 miles or less would cover their daily driving routine, while 42% want at least 300 miles before considering an electric vehicle. Only 18% of respondents said they wanted more than 400 miles.
