Edmunds drove a 2024 Mercedes-Maybach EQS SUV 680 for 368 miles on a single charge, against an EPA rating of 280 miles for the same model. That is 88 miles beyond the sticker figure, a gain of 31.3 percent, and the largest percentage overshoot among the rows reviewed on Edmunds’ range chart. The test was run at an ambient temperature of 78 degrees.

The Numbers on the Edmunds Range Chart
The row on Edmunds’ real-world EV range chart reads 368 miles tested versus 280 miles EPA. Edmunds describes the chart as a real-world complement to the EPA’s laboratory-based process, and the page does not publish a test speed or route alongside the numbers. What it does show is energy use: the EPA consumption figure for the Maybach is 44 kWh per 100 miles, while Edmunds measured 36.8 kWh per 100 miles, a 16.4 percent improvement.
The range gap and the consumption gap are different sizes because they measure different things. A truck or SUV that uses less energy per mile than the label assumes will go farther on the same battery, but the percentage change in miles does not equal the percentage change in kilowatt-hours, since range depends on both the usable pack and the consumption figure, and the chart reports each separately.
What the Maybach Is Rated For
The 280-mile rating is the figure InsideEVs reported when the Maybach’s range was announced in December 2023, in its report on the EPA range. That report put the combined rating at 280 miles with 21-inch wheels, equal to 76 MPGe, and listed a 108.4-kilowatt-hour battery that it described as estimated or unofficial. It also gave a starting MSRP of $179,900 plus a $1,150 destination charge, and a peak output of 484 kilowatts.
Those details help explain why a 368-mile result is a notable one. A 280-mile label on a vehicle with a pack of that size and a $179,900 starting price is a modest figure on paper, so a drive that lands 88 miles above it stands out. The chart does not say whether the Maybach was driven gently, and any buyer should treat 368 miles as one measured outcome rather than a promise.
The two sources agree on energy use. InsideEVs listed the Maybach at 443 watt-hours per mile including charging losses, which equals about 44.3 kWh per 100 miles, in line with the 44 kWh per 100 miles that Edmunds shows as the EPA figure. Edmunds’ tested 36.8 kWh per 100 miles is therefore roughly 17 percent below the label basis, and and a lower tested consumption figure is consistent with the extra miles.
Ambient temperature is the one test condition the chart publishes, and it ranges from 56 to 99 degrees across all vehicles. The Maybach’s 78-degree day sits near the middle of that span, which is not extreme in either direction. Edmunds does not explain how temperature figures into its results, so the number is best read as context for the run, not as an adjustment applied to the miles.
How Other Rows Compare on the Same Chart
The Maybach is not alone in beating its label. On the same chart, the 2025 Cadillac Escalade IQ is listed at 558 miles tested against 465 EPA, a gain of 20.0 percent at 70 degrees, and the 2025 Chevrolet Silverado EV work truck trim shows 539 miles against 492, up 9.1 percent at 64 degrees. The 2026 Tesla Model 3 Long Range RWD is listed at 393 miles against 363, up 8.2 percent at 68 degrees.
Against those figures, the Maybach’s 31.3 percent margin is the widest among the rows reviewed here, although the Escalade IQ gained more in raw miles, 93 against the Maybach’s 88, though some vehicles on the chart come in under their labels, and the Lucid Gravity and Lucid Air rows show the shortfalls. The rows reviewed suggest that several large electric vehicles beat their labels in Edmunds’ testing, while the amount varies with the vehicle and the conditions on test day.
For a buyer, the practical reading is narrow. Edmunds measured one vehicle on one day at one temperature, and the chart presents the result next to the EPA rating so that readers can see the difference, not so that the test replaces the label. A 368-mile result is a reason to look closely at the Maybach’s efficiency, not a guarantee of the same range under other loads, speeds or weather.
Efficiency results on the chart are not uniform either. The Model 3 row shows 21.7 kWh per 100 miles tested against a 25 EPA figure, a 13.2 percent improvement, while the 2026 Model Y Long Range Launch Series row matches its 327-mile label at 0.0 percent. Edmunds also notes that its 500-mile-plus club has five EVs and its 400-mile-plus club has eight. A tested 368 miles keeps the Maybach out of both groups, which is a useful check on the reported gain: beating a 280-mile label by 88 miles still leaves it well short of the vehicles in those clubs.
