The German car industry is in trouble. Executives and analysts alike have been sounding the alarm, as Volkswagen, BMW and Mercedes have struggled with a rapidly changing auto market. Facing a slower-than-expected EV transition and brutal competition from Chinese automakers and Tesla, these storied companies have struggled to make compelling, software-defined EVs.
But at the International Motor Show in Munich, BMW and Mercedes unveiled their best attempts yet: the iX3 and GLC electric crossovers, aimed squarely at one another. Here’s how they stack up.
What Are They?

The compact crossover segment is the biggest cash cow for luxury automakers. Vehicles like the BMW X3, Mercedes GLC and Audi Q5 have long been their brands’ respective best-sellers. And while all three of the German luxury marques have tried to electrify this segment in the past, they all got off to a rough start. The first-generation BMW iX3 was alright, but it was built in China, making it impossible to sell profitably in the U.S. Mercedes initially promised to bring the GLC-sized EQC crossover to the U.S., but lukewarm critical reception and other complications prevented it from ever getting here.
While other electric efforts from both companies have been more successful, neither has been able to match the sleek software experience or low-cost basis of a Tesla. The iX3 and GLC are both attempts to right those issues. Both offer brand-new 800-volt electronic architectures that are built from the ground up to be updatable over the air and are packed with useful software features. They each offer better efficiency than previous attempts, too, and should cost less. Finally, both represent more mature versions of their brands’ respective design languages, with the Mercedes especially demonstrating a quantum leap in design over the bubbly EQ SUVs.
Yet both are also entering a much fiercer competitive landscape than their predecessors. With everything on the line and no real room for another do-over, BMW and Mercedes have to hope their cars can stand out in a crowded field. To see which one has what it takes, I’ve put together a comparison based on what we know so far.
I’m going to focus on the GLC 400 4Matic with EQ Technology—which I will abbreviate “GLC 400” from here out, because come the hell on—and the iX3 50 xDrive. Since that’s the only version of the GLC with all-wheel drive so far, and since most Americans only buy all-wheel-drive crossovers, it’s the best point of comparison.

Both vehicles slot neatly into the shoes of their gas-powered siblings, even if neither is mechanically related to any existing gas vehicle. The GLC is slightly longer, 190.7 inches to the iX3’s 188.3 inches, but they’re both nearly exactly the same width and length.
They both ride on new electrical underpinnings too. BMW says the iX3 rides on a zonal architecture, a new style of design that typically reduces the amount of wiring and the number of computers in a vehicle. Mercedes is less clear if the GLC uses a zonal architecture, but it, like BMW, says the whole software stack is designed to be upgraded over the air.
They both use 800-volt architectures as well, which should lead to faster charging times and more efficient driving.

With 483 horsepower in the Mercedes and 469 hp in the Bimmer, you won’t be wanting for power in either car. But Mercedes has a clear edge. The GLC 400 offers up to 596 lb-ft of torque, far eclipsing the iX3 50 xDrive’s 475 lb-ft of twist.
The results speak for themselves on the drag strip. Mercedes says the GLC 400 can knock out a 4.3-second 0-62 mph sprint, while BMW says the iX3 50 xDrive will take 4.9 seconds to do the same. Both companies have a tendency to understate their cars’ performance, though, so expect quicker real-world times for each.
Still, the first category goes to Mercedes. But note that we certainly haven’t seen the best that either company can do here. I expect both to launch performance variants within the near future, so if neither seems quick enough, feel free to wait for the inevitable AMG or M-Sport versions.
Mercedes GLC EV Vs. BMW iX3: Range & Efficiency

Mercedes says the GLC 400 W/EQ Technology will offer up to 443 miles of range (713 km) on the WLTP test cycle. That cycle—used in many global markets—tends to provide far rosier estimates than the U.S. Environmental Protection Agency (EPA) cycle, which itself can be optimistic. Still, you can expect around 400 miles of range from this thing, which is more than plenty.
Yet the BMW has it beat. The iX3 50 xDrive will offer 421 to 500 miles of WLTP range (679-805 km), depending on what options and wheels you choose. That should translate to well over 400 miles on the EPA cycle in max-range spec, eclipsing the Mercedes and nearly every other electric SUV on sale.
But don’t assume that’s because the BMW is more efficient. Based on the official estimates, the Mercedes should deliver 4.7 miles per kilowatt-hour, while the BMW should get anywhere from 3.87 to 4.59 miles per kWh. Mercedes has made quite a stink about its efforts to improve EV efficiency, and based on these preliminary numbers, it is paying off. High-speed drivers may benefit, too, as the GLC will be one of the only EVs on sale to offer a two-speed transmission for high-efficiency cruising.
I’m still going to give this one to BMW, though, as U.S. customers have clearly shown they prioritize range over efficiency.

Of course, it’s also easier to make an EV more efficient when it comes with a smaller battery. The GLC squeezes its 400-mile range out of a battery with 94 kWh of usable energy. BMW fits a juicier pack into the iX3, with 108.7 kWh of usable capacity.
BMW can fit a bigger battery in part because the iX3 uses the company’s sixth-generation cylindrical battery cells. The company says the new design increases energy density by 20% and charging speeds by 30%.
Both the Mercedes and BMW batteries use nickel-manganese cobalt (NMC) lithium-ion chemistry, rather than the lithium-iron-phosphate (LFP) chemistry that is more durable, less energy-dense and far more popular in China than in Europe or the U.S., although Mercedes will offer an LFP battery in the base version of the electric CLA. Overall, there’s no clear edge for either company here.
Mercedes GLC EV Vs. BMW iX3: Charging Speed

The big benefit of 800-volt architectures is that they allow you to charge at higher speeds with less heat build-up. It’s no wonder, then, that both of these cars appear to be fast-charging champs.
The Mercedes can accept up to 330 kW of power and charge from 10-80% in 24 minutes, Mercedes says. But by that point, your buddy in an iX3 will have already unplugged and gotten back on the road. BMW claims a 21-minute 10-80% sprint, with a peak charging rate of 400 kW, which puts it at the top of our EV charging power list. The iX3 can also add 231 miles of WLTP range in just 10 minutes, while the Mercedes will recover 160 miles of range in the same time. Another point to BMW.

The iX3 and GLC exist at the cutting edge of automotive technology. Mercedes and BMW already cram their cars with so many gizmos they can make your head spin, and both are ratcheting things up for their next-generation EVs.
That means both cars offer pillar-to-pillar infotainment screens, “Hyperscreen” in Mercedes parlance and “Panoramic iDrive” in BMW verbiage. They also both offer integrated AI-powered virtual assistants, albeit with different strategies. BMW leans on its own assistant entirely, while Mercedes uses a “multi-agent approach.” Depending on what you ask the car, the GLC will use ChatGPT, Microsoft Bing AI, “conversational navigation powered by Google Gemini,” or its own Mercedes-developed assistant to help you out.
Mercedes also offers rear-wheel steering, which won’t be available on the BMW, so if navigating tight parking lots is a chief concern, the Benz may be your best bet. But both offer most of the other tech features you’d expect, including the latest generation of advanced driver assistance systems (ADAS). Both should be able to handle braking, steering and acceleration on the highway, with full stop-and-go traffic jam assistance.

For those looking to use their car as a battery backup or a mobile power station, pick your poison. The iX3 and GLC support vehicle-to-home and vehicle-to-everything technology, so you can tap into all of that onboard juice.
With both cars offering so many tech features, I can’t really crown a winner based on the spec sheet alone. Ultimately, both companies have struggled to make software that is as intuitive and well-integrated as what you’d get in a Tesla, BYD or Rivian. The winner here will be whichever company figures out how to take all of this technology and make it transparent and simple for the end user. Both companies argue that they have made huge strides in this department, but we’ll have to test them both ourselves before we buy that claim.
For now, this is another tie.
Mercedes GLC EV Vs. BMW iX3: Pricing & Release Date

BMW says the iX3 50 xDrive will start at under $60,000 when it arrives in the summer of 2026. But when the less potent iX3 40 sDrive (RWD) and 40 xDrive arrive later on, pricing will start at under $55,000. That’s a great deal given that the gas-powered X3 starts at around $52,000. Note, however, that German car prices tend to balloon when you add common-sense options. In the real world, you’re probably going to end up paying more than $60,000.
Unfortunately, Mercedes has not released pricing for the GLC yet, so we can’t compare them. We know that the GLC 400 4Matic With EQ Technology is set to launch in late 2026, with the rear-wheel-drive GLC 300+ coming in early 2027. But for now, pricing is up in the air.
Mercedes GLC EV Vs. BMW iX3: Early Verdict

The Mercedes GLC 400 with EQ Technology is faster and more efficient than the BMW iX3 50 xDrive, with seemingly more AI features and available rear-wheel steering. But the Bimmer offers more range, faster charging speeds and a design that I personally find more compelling.
That makes them relatively evenly matched on paper. But these cars aren’t going to live or die on paper. They’re going to succeed or fail based on how well they integrate their sophisticated technology into a compelling, reasonably priced package. I can’t say whether either company will get it right. But neither can really afford to get it wrong.
