2025 Mercedes-Benz G 580 EV Tested: Our New Favorite G-Wagen

• The G 580 is the fully electric version of the 2025 Mercedes-Benz G-Class.
• It offers AMG G 63 levels of performance.
• We saw 266 miles of real-world driving range on the Edmunds EV Range Test.

G 580 EV real-world range test

The electric G-Class completed 266 miles on the Edmunds EV Range Test, an 11% improvement over its 239-mile EPA estimate. Obviously, this isn't a great showing in a world where 300- and even 400-mile ranges are quickly becoming the norm. But considering the fact that the G 580 EV is a 6,913-pound SUV with the aerodynamic profile of a brick, 266 miles really isn't that bad.

As for total energy consumption, our testing showed 47.6 kWh per 100 miles. That's also a solid improvement over he EPA's estimate of 54 kWh per 100 miles.

How we range test

Every vehicle driven on the Edmunds EV Range Test follows the same set of parameters. We aim for an average speed of 40 mph, with 60% city driving and 40% done on the highway. We believe this better represents the real-world conditions of EV drivers, rather than just setting the cruise control at 70 mph and hitting the highway.

We started the G 580 at Edmunds' headquarters in Santa Monica, California, with a 100% state of charge and stayed within 5 mph of all posted speed limits. We returned with 10 miles of indicated range remaining, which is standard practice, simply for safety purposes.

G-wagen hits the track

The G 580 EV has a 116-kWh (usable) battery pack and four electric motors, one at each wheel. Total output is a massive 579 horsepower and 859 lb-ft of torque — increases of 136 hp and 446 lb-ft over the 3.0-liter turbocharged inline-six in the G 550 we recently tested. Of course, weighing in at the aforementioned 6,913 pounds, the electric G-Class is also 1,224 pounds heavier than the G 550.

By our stopwatch, accelerating to 60 mph in the G 580 took 4.4 seconds, and the electric G-wagen ran the quarter mile in 12.7 seconds at 107 mph. For comparison, the G 550 did 0-60 mph in 5.1 seconds and took a full second longer to complete the quarter mile. For additional perspective, the numbers we got from the G 580 EV all match what we saw when we tested the Mercedes-AMG G 63 in 2023: 4.4 seconds to 60 mph and a 12.7-second quarter mile at 107.7 mph. The updated 2025 G 63 might show some gains, but we won't know until we get one on the track.

In our 60-0 mph braking test, the G 580 took 110 feet to come to a stop, where the G 550 did the same deed in 108 feet. Both numbers are an improvement over the 2023 G 63, which needed 117 feet to stop from 60 mph.

Lastly, on our 200-foot lateral skidpad — a place where driving any G-Class is downright hilarious — the G 580 EV pulled 0.84 g. That's a massive improvement over the G 63's 0.74 g, largely thanks to the EV's big battery pack and lower center of gravity. We don't have data for the new G 550, as our skidpad was under construction during that test day.

Final thoughts

Electric power perfectly suits the Mercedes-Benz G-Class. It offers the same immediate thrust that you'd expect from the AMG G 63, and the G-Class hasn't lost any of its curb appeal in the process. This SUV can still tackle any off-road task, and in many ways, it's actually better, what with the ability to manage power delivery at each individual wheel. Yes, you will miss the grumble of the V8 engine (with side exhaust pipes). But that's a small complaint in the grand scheme of things. We'd take the G 580 over other gas-powered G-Class models any day.
