New Mercedes GLB Goes Big On Screens And Stars

Mercedes has kicked off the teaser campaign for the new generation GLB, ahead of its debut on December 8. It follows in the footsteps of the CLA and features a high-tech interior with seating for up to seven people.

Details are still under wraps, but Mercedes confirmed that the GLB will feature an optional MBUX Superscreen. The setup is expected to combine a 10.25-inch digital instrument cluster with a 14-inch central infotainment screen and a matching 14-inch passenger display.

Buyers will also find the latest Mercedes-Benz Operating System, which features an MBUX Virtual Assistant with avatars as well as Google Maps navigation. We can also expect plenty of artificial intelligence.

Technology aside, the GLB has circular air vents and a floating center console. The latter houses large cup holders and an available wireless smartphone charger. They’re joined by a new steering wheel as well as five- and seven-seat configurations.

What Else Is New Inside?

Mercedes wasn’t ready to talk numbers, but they revealed the redesigned crossover has “noticeably more headroom in the first two rows of seats.” Second-row passengers will also find additional legroom, added thigh support, and an adjustable backrest.

Third-row occupants haven’t been forgotten as entry and egress has been improved. When not needed, the rear seats fold into the load floor.

A panoramic glass roof comes standard and customers can upgrade to a fancier version that can transition from clear to opaque in a matter of milliseconds. Customers can also get an illuminated roof that features a “starry sky.”

Speaking of the roof, it features heat-insulating laminated safety glass as well as an infrared-reflecting coating. Mercedes says this keeps the interior cool in summer, while also minimizing heat loss in winter.

The GLB will come with a “comprehensive range of driver assistance systems.” These will be supported by “eight cameras, five radar sensors, 12 ultrasonic sensors, and a water-cooled high-performance computer with sufficient power reserves for future functions and regular over-the-air updates.”

Testing Continues

With a debut less than a month away, the automaker is wrapping up testing at the Mercedes Technology Center in Sindelfingen. As part of this effort, the GLB is being subjected to cold-weather testing in climatic wind tunnels that can simulate temperatures of up to -40° F (-40° C).

Mercedes added the tunnels have cutting-edge snow cannons that can “simulate fierce blizzards where snowflakes race towards the test vehicle at speeds of up to 124 mph (200 km/h).”

These tests appear to have paid off as the upcoming GLB EQ heats the interior twice as fast as its predecessor on a 20‑minute drive in temperatures of 19.4° F (-7° C). This undercuts the heating time of a conventionally powered model and it uses half the energy as the outgoing EQB.

The company went on to say the added efficiency increases range and can be partially chalked up to an innovative heat pump. It collects waste heat from the electric motors and battery as well as from ambient air.

Electric And Hybrid Powertrains

Mercedes didn’t mention performance specifications, but the GLB EQ will presumably have an 85 kWh battery pack as well as at least two powertrains. The entry-level variant could have a rear-mounted motor developing 268 hp (200 kW / 272 PS) and 247 lb-ft (335 Nm) of torque.

We can also expect a dual-motor all-wheel drive system producing a combined output of 349 hp (260 kW / 354 PS) and 380 lb-ft (515 Nm) of torque.

Customers can also look forward to an assortment of hybridized powertrains that consist of a 1.5-liter four-cylinder engine, a 1.3 kWh battery pack, and an eight-speed dual-clutch transmission with an integrated electric motor. In the European CLA, this provides outputs of 154 hp (115 kW / 156 PS) and 206 lb-ft (280 Nm) as well as 181 hp (135 kW / 184 PS) and 243 lb-ft (330 Nm).
