Mercedes-Benz’s redesigned compact model family is almost complete but there’s still one model that hasn’t been unveiled yet.

We’re talking about the bodystyle that has the potential to become the best-selling nameplate of them all, the GLA compact crossover. Sure, the Mercedes-Benz GLB looks set to be a highly successful model as well, but the GLA might have the edge over its boxier sibling given that it should be cheaper.

We’ve already seen next-generation GLA prototypes during testing and the general impression is that we’re dealing with a jacked-up A-Class from a styling standpoint. That’s hardly surprising since the same was said about the first-generation GLA.

Now we’ve come across a new set of spy shots that give us the first look inside the 2020 Mercedes-Benz GLA, revealing the close connection to the A-Class. Basically, we’re looking at the same dashboard dominated by the MBUX infotainment system’s Widescreen Cockpit display.

The steering wheel is identical too, as are the turbine-style air vents and center console. Obviously, we should ignore the big screen located in front of the climate control area as it’s there for testing purposes only.

On the outside, the 2020 GLA continues to be completely covered in camouflage but that can’t disguise the fact that it will look very similar to the A-Class, bar the increased ride height and SUV-like elements. Expect more rugged details such as plastic cladding surrounding the wheel arches and the beefier bumpers, as well as skid plates under the bumpers.

The second-generation Mercedes-Benz GLA should offer the same assortment of turbocharged gasoline and diesel engines as the A-Class in Europe, including the new 1.3-liter petrol unit developed together with Renault. AMG-branded GLA 35 and GLA 45 versions should also become available with up to 302 hp and 416 hp, respectively.
