Mercedes-Benz unveiled the all-new electric C-Class on Monday, presenting what it described as the most ambitious reinvention of the model in its history. The car, designated the C 400 4MATIC Electric, is powered entirely by a battery and will go on sale in the United States in the first half of 2027. Its arrival marks a defining moment not only for Mercedes but for the broader premium midsize segment — a market still dominated by internal combustion competitors that have been slow to embrace full electrification. “The all-new electric C-Class is redefining the mid-size segment for electric vehicles,” said Ola Källenius, the company’s chief executive, in a statement. He described it as “the most powerful and sportiest C-Class we’ve ever built.” That is a notable claim for a model whose reputation has long rested more on refined comfort than outright performance. But the numbers behind it are hard to dismiss. Range, Power and a Ten-Minute Promise The new C-Class launches with a single powertrain configuration — a dual-motor, all-wheel-drive setup producing 482 horsepower, capable of accelerating from zero to 60 miles per hour in 3.9 seconds. Those figures put it squarely in the territory of dedicated performance sedans, a segment Mercedes has traditionally addressed with its AMG division rather than a base model. On range, the company is equally aggressive. The new C-Class carries a 94-kilowatt-hour lithium-ion battery and, under the European WLTP testing cycle, is rated at up to 762 kilometers — roughly 473 miles. Real-world range figures in the United States, measured under the EPA’s more conservative methodology, will almost certainly come in lower, but even a significant discount would place the car well above the current midsize electric field. More striking is the car’s charging capability. Using 800-volt DC fast-charging infrastructure — the same high-voltage architecture found
