2-Line Blurb

140-Character Blurb

The 2026 Mercedes-Benz GLC is a high-tech, luxurious, and spacious compact luxury SUV that’s a bestseller for all those reasons and more.

Cons

<ul>
<li>Resale value only average</li>
</ul>

Driving Impressions

The non-AMG models in the 2026 GLC SUV lineup don’t put speed and acceleration at the forefront of the driving experience. Still, they’re quick, nonetheless, with the base GLC 300 capable of 5.9-second zero-to-60-mph runs, the 4Matic all-wheel-drive GLC 300 good for 6.0 seconds, and the GLC 350e plug-in hybrid electric vehicle (PHEV) doing the deed in 6.3 seconds.
You might notice that the GLC 350e is the slowest of the group, despite also being the most powerful. Both of those traits are due to the presence of the PHEV system, which, although it boosts total output, also weighs enough to counteract that extra power, at least if acceleration from a stop.
Fuel Economy
The GLC 350e’s extra PHEV bits also mean it’s slightly less efficient after you’ve depleted the battery, earning a 25 mpg combined EPA rating versus the mild hybrid GLC 300’s 26 mpg combined. Both variants are on par for the compact luxury SUV segment, most earning between 25 and 29 mpg combined.
That said, the GLC 350e is rated at 64 MPGe when you take its impressive all-electric range of up to 54 miles into account.

Familiar Face

Exterior

A thing of evolution rather than revolution, the GLC’s exterior style hasn’t changed much over the years but has kept up with the times. That’s fine in our book, as good design is timeless, and the GLC is definitely a good design. Despite its smaller footprint, the GLC has a presence that immediately marks it as a Mercedes-Benz.
If the standard SUV version of the GLC doesn’t keep your visual interest, don’t forget there’s a coupe variant, too, as well as high-performance AMG models with their own, subtly aggressive style.

FAQs

Favorite Features

MBUX
The latest iteration of Mercedes-Benz’s infotainment software includes standard wireless Apple CarPlay and Android Auto, as well as “Hey, Mercedes” voice-activated controls. It’s easy to use and fully featured.
4Matic AWD
If you frequently encounter slippery conditions or inclement weather, you’ll appreciate the extra surefootedness of 4Matic all-wheel drive (AWD). Should you venture a bit further off-road, there’s even an off-road mode and a virtual “transparent hood” feature.
Burmester audio
Underpinning the enjoyment of every drive, this 13-speaker, 390-watt audio system is crisp, clear, and well worth the upgrade.
Parktronic with Active Park Assist
The GLC is certainly nimble enough, but a little extra assistance with tricky parking spots is always welcome. Best of all, this system is standard on all GLC variants, rather than a pricey extra.
Driving Assistance Package
Although this package isn’t standard, it’s another worthy upgrade. It brings adaptive cruise control, intersection turning assistance, evasive steering assistance, and more to the table. It’s a welcome peace of mind, especially when you have family and friends in the vehicle.
Augmented reality video
Another high-tech extra, this system comes with the Pinnacle trim. As the name implies, the GLC’s augmented reality video system overlays important information, including turn-by-turn directions, over a video display of the outside world, making it easy to find that hidden drive or tricky left-hander.

High-End Cabin

Interior

The 2026 Mercedes-Benz GLC&#8217;s interior remains one of its primary strengths. The cabin is spacious, high-tech, and well-made, with excellent materials and a modern design. A 12.3-inch digital instrument panel and an 11.9-inch central touchscreen are standard equipment.
In the second row, you&#8217;ll find a generous 37.4 inches of legroom, about the same as the Audi Q5 offers, and just over an inch more than the BMW X3. Cargo space is good in the GLC, too, with 21.9 cubic feet behind the rear seats, a bit less than the Q5&#8217;s 25.4 cubic feet and considerably less than the X3&#8217;s 31.5 cubic feet. Still, the GLC offers plenty of cargo space for a few carry-ons and other travel necessities, even with both rows occupied.

Trims

Under the Hood

The 2026 GLC offers two core powertrains. The first, the GLC 300, gets a turbocharged 2.0-liter 4-cylinder engine and 48-volt mild hybrid system mated to either front-wheel drive (FWD) or 4Matic all-wheel drive. The turbocharged 4-cylinder generates 255 horsepower and 295 lb-ft of torque in both guises, and both variants use a 9-speed automatic transmission.
The other powertrain is the GLC 350e, a plug-in hybrid electric vehicle (PHEV). It uses an electric motor, a substantial battery pack, and a 2.0-liter turbocharged 4-cylinder engine for a total output of 313 hp and 406 lb-ft of torque. The GLC 350e comes with all-wheel drive and a 9-speed automatic transmission as standard equipment.
4-Year/50,000-Mile Warranty
Mercedes-Benz offers four years or 50,000 miles of powertrain warranty coverage, whichever happens first. These terms are typical among luxury automakers.
Safety Ratings
This generation of the GLC has been named a Top Safety Pick+ by the Insurance Institute for Highway Safety (<a href="https://www.iihs.org/ratings/" target="_blank" rel="noopener">IIHS</a>), the institute’s highest accolade. Standard safety equipment includes blind-spot monitoring with rear cross-traffic alert.

What's new for 2026

The 2026 Mercedes-Benz GLC carries forward into the new model year largely unchanged with just a few package feature tweaks. Nineteen-inch wheels are now available at no extra cost.

The all-electric 2026 BMW i5 midsize luxury sedan is eminently worthy of the famed blue-and-white badge and all that entails. Maximum range is 310 miles.

<ul>
<li>M60 seats could be comfier</li>
</ul>

Power, Ride, and Handling

The i5 eDrive40 employs one electric motor, driving the rear wheels with a substantial 335 horsepower and 295 lb-ft of torque. It sprints from a standstill to 60 mph in just 5.7 seconds. For some context, the entry-level Audi A6 Sportback e-tron has a maximum of 375 hp and can do the zero-to-60-mph dash in 5.2 seconds.
The xDrive40 adds another electric motor to drive the front axle, making a total of 389 hp and 435 lb-ft of torque. It will get up to 60 mph in 5.2 seconds. For reference, the all-wheel-drive version of the A6 Sportback e-tron develops 456 hp and does it in 4.3 seconds.
At the top of the entire 5 Series lineup stands the i5 M60, with two electric motors, all-wheel drive, plus a considerable 590 hp and 586 lb-ft of torque. The M60 hits 60 mph in 3.7 seconds, which is fabulously fast.
The i5 M60 has an adaptive suspension as standard, for a broad spectrum of comfort and sport settings. It also has rear-wheel steering (which BMW calls Integral Active Steering) helping the car track through fast corners in a spectacular manner. That said, this doesn’t feel exactly like the kind of M car we’ve grown to know and love. The steering turns the front wheels, but there’s no sensation of a real connection. The wheel also feels slightly too thick for our tastes. While we’re on this negative trail, the front sport seats didn’t feel that comfortable to us. But we’re prepared to give BMW the benefit of the doubt because they might prove to be supportive over a longer drive.
Overall, though, the i5 is smooth, silent, and fast. Even the famed BMW 50:50 weight distribution (for a great balanced feel) makes it into every i5. It also has some smart technology to help the driver, like keeping a safe distance from the vehicle in front, even when adaptive cruise control isn’t activated. After a while, we felt the cooling system in the driver’s seat switch itself on. And all it takes is a voice command to perform various functions. We said, “Hey, BMW, activate massaging for the driver’s seat” and it happened straight away.
We looked for steering-wheel paddles to change levels of brake regeneration, but just found a Boost paddle instead, so that was a different kind of fun. We discovered that the key to one-pedal driving — where speeding up and slowing down is done just by how much pressure is on the accelerator, with the brakes only being used for more urgent halts — is to put the shifter into B mode.
<h3>Range and Charging</h3>
The i5 eDrive40 has a maximum range of 310 miles (up from 295) on 19-inch wheels. That’s good, even if it’s not breaking any boundaries. By comparison, the Audi A6 Sportback e-tron stretches 392 miles, while the Mercedes-Benz EQE sedan runs for 308 miles.
The 2026 i5 xDrive40 is rated at 278 miles (up from 266). We will update this section with the i5 M60’s range when the information becomes available. The 2025 model has a 253-mile range.
Another important aspect of an electric car is how fast it can charge. The metric here is taking the battery from 10% capacity to 80% using a DC fast charger. BMW says the i5 performs this task in 30 minutes. The Audi A6 Sportback e-tron can be nine minutes down the road when an i5 driver unhooks the charging cable. However, this is still acceptable in the present state of electric vehicle (EV) technology.

Evolved Exterior

BMW has its distinct design language, which could be an acquired taste for some. But we think the looks of the i5 (and the 5 Series in general) aren’t so polarizing that they would be deal-breakers. Considering how adventurous BMW has been with other vehicles, there’s something pleasantly conventional about this car — like it’s an evolution of previous 5 Series generations. There are 14 paint choices, including no-cost white, plus a couple of special Frozen finishes. One option to add a bit of glitz is an illuminated grille.

Our Favorite Features and Tech

BMW Curved Display 
Every new i5 comes with this impressive one-piece unit housing a digital instrument cluster and the infotainment touchscreen.
Automatic Park Assistant 
This standard self-parking feature works for both perpendicular and parallel spaces.
Interaction Bar 
Spanning the dashboard&#8217;s width, this standard feature has touch-control functions for the front passenger and the ability to blend in with the cabin’s multicolored ambient lighting.
AirConsole 
This video gaming platform is offered for the first time, with 15 titles available. Players use their phones as controllers. It’s one way of passing the time while the i5 recharges its battery.
Bowers &amp; Wilkins surround-sound system 
Optional in the eDrive40 and xDrive40, standard in the M60, we’re big fans of B&amp;W audio systems for their clarity and power.
Driving Assistance Professional package 
We think this option is worth the investment. This bundle includes a Highway Assistant for hands-free (but not eyes-free) driving, plus evasive steering assistance, active lane-changing assistance, side collision protection, and front cross-traffic warning.

Classy Interior

Veganza is not some promotion at Whole Foods, but the name of a vegan-friendly simulated (and perforated) leather used on the seats, door panels, and even the steering wheel. The real stuff is available as an option.
The i5 doesn’t have conventional air vents either. BMW calls them seam vents and they’re extremely low-profile, in a line going across the dash. Overall, the i5’s cabin has high-quality materials and a restrained design that adds to the classiness. It also offers typical BMW extras like glass controls (which may not be everyone’s idea of tasteful), a Panoramic Sky Lounge roof, and powered shades for the rear windows.
Sitting up front, we really like the cushioned areas right where we’d rest our elbows. And rear passenger space is absolutely fine for an adult male of average size.
Trunk space is 17.3 cubic feet, a little less than the 18.4 cubic feet in the combustion-powered 5 Series (because of the i5’s battery), but generous nonetheless. The rear seats can also split and fold in 40/20/40 fashion.
