Thanks to the US Patent Office.
The 2020 Mercedes-AMG GLB35 is currently the most powerful version of the subcompact GLB with 306 horsepower and 295 lb-ft of torque coming from a 2.0-liter turbocharged four-cylinder. But we had our suspicions that it would not be the most powerful version for long with a hotter GLB45 model soon to be introduced.
The GLB45 has already been spotted in spy shots but now we have an even better look at the car from these design filings with the United States Patent and Trademark Office. The filings were submitted by Daimler AG, the parent company of Mercedes-Benz, back on May 8, 2019, but were only recently approved on June 9, 2020.
None of the six pages in the filings mention the GLB45 by name but since the GLB250 and GLB35 have already been released, there is no other model that this could be. The design images clearly show the signature Panamericana grille, signifying that this is, in fact, an AMG car. In the back, quad exhaust pipes clearly show that this is the 45 model, and not the lesser 35 version, which only has two pipes. The rest of the design looks broadly similar to the GLB35 but there appears to be larger cooling ducts below each of the headlights.
The complete picture should come into focus when we see the real car shown with wheels and color instead of just patent images. Power will likely come from the same 2.0-liter four-cylinder used in the 2021 Mercedes-AMG GLA45, which produces 382 hp and 354 lb-ft of torque. A more powerful version of this same engine produces 421 hp in the CLA45 S but this tune has not been made available on any US-spec models. We expect the GLB45 to possess similar performance as the GLA45, which can hit 60 mph in 4.3 seconds on its way to a 155 mph top speed. A reveal could take place by the end of 2020.
