What makes this compact luxury SUV stand out

If you’re hunting for the most fuel-efficient German luxury SUV, size matters—you’ll want to go small.
Among compact luxury crossovers, the 2026 Mercedes GLA 250 takes the crown for frugality.
And just to be clear, this doesn’t include PHEVs—we’re talking pure gas efficiency here.
Gets 29 mpg on average

It’s no surprise that the most fuel-efficient GLA skips all-wheel drive. The front-wheel-drive version hits a combined 29 mpg, with 26 in the city and 34 on the highway.
Other German contenders include the redesigned 2026 Audi Q3 and the 2026 BMW X1. Both come standard with AWD, which naturally makes them a bit thirstier.
The 2026 Q3 hasn’t been EPA-rated yet, but with standard Quattro AWD, it probably won’t beat the FWD GLA’s numbers.
Peppy turbocharged performance

That fuel efficiency pairs with a lively 2.0-liter turbo four producing 221 horsepower and 258 pound-feet of torque. It’s hooked up to an eight-speed dual-clutch automatic, which helps the GLA hit 0–60 mph in just 6.8 seconds.
What’s neat is that it’s the only one in this small German luxury SUV class with a mild 48-volt hybrid system, giving it a tiny electrified boost.

The GLA 250 is close to the BMW X1 xDrive28i and Audi Q3 in performance, but it comes in as the least powerful of the trio.
The X1 packs 241 horsepower, while the Q3 cranks out 255, both from their own 2.0-liter turbo fours.
Unsurprisingly, the Q3’s extra power gives it the quickest sprint, hitting 0–60 mph in just 5.5 seconds.

All the other features that make the GLA shine
Comfort, tech, and extras that round out the package

The 2026 Mercedes GLA is your entry ticket into the brand’s lineup.
Interestingly, the CLA isn’t the cheapest way in right now, since the compact sedan isn’t being offered with a gas engine at the moment.
For 2026, the GLA is the most affordable Mercedes you can get, giving buyers a taste of the brand without breaking the bank.

Now in its second generation, the 2026 GLA keeps that hatchback-on-stilts look. It’s not rugged, and the black cladding doesn’t make it feel imposing—but that works in its favor.
What you get is a small crossover that feels stylish and youthful. Up front, the wide grille proudly shows off Mercedes’ three-pointed star.
Sleek LED headlights and satin silver trim on the lower bumper give the front end a touch of sophistication.

The GLA comes standard with 18-inch wheels, which already look sharp.
If you want to step it up, you can go bigger—or spring for the $3,300 AMG Night Package.
That package adds the AMG exterior, 19- or 20-inch wheels, sport brakes, and a few interior touches that make the GLA feel more athletic and premium.
Upscale feel inside

The 2026 GLA is a bit taller than before, giving you a slightly loftier driving position. It hits that “just right” zone—not too low, not too high—for people of all ages.
Step inside, and the cabin feels upscale, with soft-touch surfaces almost everywhere. Lower door panels and dash areas stick to harder materials, which is normal for this class.
Standard MB-Tex synthetic leather and glossy silver trim look good, but you can upgrade to real leather and aluminum or wood accents for a truly luxurious feel.
Credit: Mercedes-Benz
The cabin is roomy for a small SUV, though it can’t match the space of a GLC.
Tech is solid, with MBUX infotainment and dual 10.25-inch displays on every model. Optional packages let you customize the experience further.
The Exclusive Trim adds perks like 64-color ambient lighting, smart entry, and wireless charging. The Pinnacle Trim stacks on a panoramic sunroof, navigation, a premium sound system, and a 360-degree camera.
One downside: driving assists like adaptive cruise control are optional, which feels stingy compared with even basic compact cars.

How the Audi Q3 and BMW X1 compare to the GLA

If the GLA 250 is on your radar for its fuel efficiency, it’s worth giving the X1 xDrive28i and Audi Q3 a look too.
Compared with the GLA, each of these small German SUVs brings its own strengths to the table.
Audi Q3: Leading the pack in power

The 2026 Audi Q3 is just hitting dealerships, and as the newest small luxury SUV, it has plenty going for it.
In North America, the S Line exterior comes standard, giving the Q3 a bit of an edge in style right out of the gate.
Inside, the cabin feels modern and fresh, though we’ll have to get behind the wheel to see if it truly lives up to “premium.”

Honestly, the Q3’s latest MMI infotainment might be the easiest of the three German brands to use. Its interface is clean, simple, and not overwhelming like some rivals.
BMW’s colorful iDrive 9 feels a bit abstract and almost gimmicky in comparison, but the Q3 backs up its tech with serious performance. It’s actually the fastest to 60 mph among these small German luxury SUVs.
One thing to watch: Audi combined the wiper and gear selector into a single multifunction stalk. Make sure that setup works for you before buying.

BMW X1: Space and versatility

If practicality is high on your list, the X1’s upright, conventional shape gives it the most flexible interior.
Compared with the Q3 and GLA, which lean into the hatchback-on-stilts style, the X1 sticks to a classic SUV silhouette.
That traditional shape isn’t just for looks—it translates into more usable interior volume and a roomier feel inside.
Credit: BMW
The X1 has earned a reputation as the sportiest of the small German luxury SUVs. Pair that with a practical interior, and it’s no surprise the X1 outsells both the GLA and Q3.
That said, Mercedes has the GLB, which is closely related to the GLA, so buyers are split between the two models.
