Mercedes-Benz is currently engaging in a pocket rocket assault, debuting a slew of new sub-compact models. We've already seen the new A-Class and CLA in their base forms and performance-oriented AMG 35 variants with over 300 horsepower. There are also more hardcore AMG 45 variants on the way, which will pack over 400 hp.

Mercedes is also planning a brand-new SUV called the GLB, which will be based on the same platform as the A-Class and CLA and will come in an AMG 35 flavor as well. But the GLB won't be the only sub-compact crossover in the Mercedes lineup. Autocar reports that another nameplate is set to come back with massive improvements.

The new MFA platform will also spawn a second generation GLA, which will sit below the GLB and compete against the Audi Q3, BMW X1, and Volvo XC40. Autocar says the new GLA will make its debut later this year at the 2019 Frankfurt Motor Show in September. Unlike the GLB, which adopts a boxy, G-Wagon-inspired aesthetic, the GLA will retain its more curvaceous shape.

In the US market, we expect the GLA to be powered by the same 2.0-liter turbocharged four-cylinder engine that's found in the A220 and CLA250. But it is still unclear exactly what level of output the base GLA will have when it arrives on the market. The GLA could be badged as a 'GLA 220' and produce 188 hp like the A220, or as a 'GLA 250' with 221 hp like the CLA 250. The former could be more likely since it would leave room for the GLB to line up with the pricier CLA's power output.

It is also likely that the GLA will receive its own AMG 35 variant with over 300 hp and the GLA 45 could make a return with over 400 hp on tap. The GLA will also benefit on the interior with the introduction of the new Mercedes-Benz User Experience (MBUX) infotainment system. Mercedes hasn't made any official announcement as of now, but will likely tease the car closer to its reveal in September.
