The 2026 Mercedes-Benz GLB SUV channels the commanding presence of Mercedes-Benz's full-size lineup into a compact, city-ready package — blending confident SUV character with the everyday flexibility that drivers in Ontario, Rancho Cucamonga, and Fontana demand. Stop by Mercedes-Benz of Ontario to see this versatile SUV up close and discover the range of configurations available.
The 2026 GLB preserves its trademark upright stance and extended wheelbase, setting it apart as one of the most cleverly engineered vehicles in the compact SUV segment — with the ability to seat up to seven passengers while still navigating tight urban streets with ease.
Utility extends well beyond the GLB's cabin, thanks to standard aluminum roof rails engineered to accept a wide range of accessory mounts — ideal for carrying bikes, skis, surfboards, and more on the road from Ontario to Chino. Compatible accessory attachments are available through our parts department.
An optional panoramic sunroof spanning the first and second rows transforms the GLB's cabin atmosphere, bathing passengers in abundant natural light throughout every drive. Please note that operating the sunroof while a roof carrier is mounted to the aluminum roof rails is not recommended.
The 2026 Mercedes-Benz GLB SUV arrives loaded with advanced connectivity tools and intelligent driver assistance features, ensuring every trip through Ontario, Corona, and beyond is both safer and more seamlessly connected than ever before.
Twin 10.25-inch displays run the latest MBUX platform, delivering wireless Apple CarPlay, Android Auto, four USB-C ports, and a standard wireless charging pad to keep every device powered and paired. Mercedes me connect services extend control even further, letting you monitor and manage your GLB remotely from your smartphone.
Standard safety equipment on the 2026 GLB includes automated emergency braking with pedestrian detection, blind-spot monitoring, and a driver attention monitor to help keep every commute secure. A network of ten cameras, five radar sensors, and 12 ultrasonic sensors provides a thorough picture of the surrounding environment, while over-the-air updates keep all systems current without a dealership visit. An available Driver Assistance Package layers on adaptive cruise control, lane-keeping assist, and evasive steering assist for an even higher level of confidence.
Buyers looking to personalize their 2026 GLB further will find an impressive selection of premium additions, including a 360° surround-view camera system that makes parking effortless in any environment, a Burmester® Surround Sound System with Dolby Atmos for a truly enveloping audio experience, and an available head-up display that projects essential driving information directly into the driver's field of vision.
Inside the 2026 Mercedes-Benz GLB SUV, every element is crafted to work in harmony with your lifestyle — from a smartly adaptable cabin and intuitive voice controls to an impressive lineup of standard features that come equipped on every trim level.
Despite its city-friendly dimensions, the GLB conceals a remarkably generous interior — an available third-row seat brings total occupancy to seven passengers, a distinction that remains exceptionally rare among compact SUVs.
A simple "Hey Mercedes" voice command puts navigation, climate settings, music, and more under your control without ever reaching for the screen. The upgraded MBUX system interprets natural, conversational language and gradually adapts to your preferences, delivering a more personalized experience with every journey through Ontario and Inland Empire.
Every 2026 GLB rolls out of Mercedes-Benz of Ontario equipped with dual-zone automatic climate control, heated power front seats with memory function, 64-color ambient lighting, and dual 10.25-inch digital displays as standard features — ensuring a polished, premium experience from the very first drive.
