Mercedes has unveiled the primary official pictures of the inside of the upcoming Mercedes GLB, together with exterior photos from low-temperature laboratory exams, through which the automobile is roofed by a thick layer of ice.
The Mercedes GLB is the third mannequin within the model’s new compact vary. Following the Mercedes CLA and CLA Capturing Brake, the brand new Mercedes GLB can be formally revealed on December 8, 2025, on the Mercedes Know-how Middle in Sindelfingen.
Earlier than its public debut, Mercedes carried out closing laboratory exams simulating operation below chilly situations. The truth is, the temperature vary within the so-called “chilly tunnel” extends from –40°C to +40°C, protecting nearly the complete vary of temperatures that could be encountered in several areas of the world.
Excessive-temperature exams have been additionally carried out, with the thermal chamber able to simulating temperatures from –10°C to +60°C. Moreover, there’s a photo voltaic simulation system with 32 lamps, offering a radiation spectrum equal to pure daylight. On a floor of 8 by 2.5 meters, the radiation depth can fluctuate between 200 and 1,200 watts per sq. meter.
In every tunnel, a “rolling street” simulates the driving floor. Highly effective electrical motors drive 4 rollers every, permitting 4MATIC fashions to be examined below real looking situations.
The brand new Mercedes GLB efficiently handed the low-temperature exams. Inside simply quarter-hour at –15°C, the windshield utterly defrosted—with out activating the wipers. And after solely 20 minutes of driving at –7°C, the cabin warmed up twice as quick as that of the earlier mannequin, with the electrical model of the GLB consuming solely half the power of its predecessor.
This spectacular effectivity is due to a brand new warmth pump system tailored from the Imaginative and prescient EQXX idea.
To accompany the discharge of the official cold-weather take a look at pictures, Mercedes additionally shared a number of photographs of the inside. Like its predecessor, the brand new GLB can be provided in five- and seven-seat configurations, and Mercedes guarantees extra headroom within the first two rows due to the brand new roofline and the usual panoramic roof.
The sliding second-row bench is optionally available within the five-seat model and customary within the seven-seater. Entry to the third row is simpler as a result of longer sliding vary of the rear bench. When not in use, the third-row seats fold flat into the ground.
For photo voltaic safety, the panoramic roof is thermally insulated, that includes an infrared-reflective layer and a LowE (low-emissivity) interior coating, which reduces cabin heating throughout summer season.
In winter, the LowE layer minimizes warmth loss by reflecting inside heat again inside. At simply 200 nanometers thick, this infrared movie is way thinner than a human hair, which measures about 50,000 nanometers in diameter.
Optionally, the transparency of the panoramic roof may be adjusted section by section in 10–20 milliseconds. Passengers can select between a clear mode for a transparent view exterior and an opal (milky) mode for extra privateness. The opal mode not solely prevents prying eyes but in addition reduces glare in direct daylight. Management is out there via a devoted menu within the automobile’s central show.
For an additional contact of luxurious, the big panoramic roof may even be illuminated. Every section connects to the ambient lighting system, creating a personalised “starry-sky” impact, with mild guided by front-mounted LED modules.
The multimedia system is carried over from the brand new CLA, which was just lately examined, and runs on Mercedes’ proprietary MB.OS working system. The bottom setup features a 10.25-inch show for the digital instrument cluster and a 14-inch multimedia display screen, whereas a further 14-inch passenger show is optionally available. No matter whether or not the passenger display screen is chosen, Silver Shadow-finished air vents are positioned on the outer edges of the triple-display dashboard.
As with the CLA, the brand new steering wheel options two rocker switches—one for the Distronic adaptive cruise management and one for audio quantity—changing the touch-sensitive controls from the earlier technology.
The brand new Mercedes GLB will go on sale in spring 2026, with pricing to be introduced. Just like the CLA, it is going to be accessible in each electrical and 48V mild-hybrid variations.
