Why would Mercedes fit a test mule with wider fenders and have it hauling a trailer?
Mercedes-Benz has impending updates for its entire small car range, including additions like the A-Class Sedan and possibly even a GLB-Class crossover. All of these models share versions of Mercedes' new Modular Front-Wheel-Drive Architecture 2 platform, MFA2 for short, so the company can be somewhat sneaky by developing one vehicle under the guise of another. Case in point: this video catches what's likely the next-gen GLA-Class under a lightly modified version of the future A-Class.
The fender extensions at the front and rear are the big giveaway that this isn't a run-of-the-mill A-Class test mule. Plus, Mercedes probably wouldn't have much reason to test its five-door hatchback's ability to haul a trailer. As further evidence that this is for GLA-Class development, the company has already been caught using a disguised A-Class to evaluate the new crossover in the past.
Spy shots have already caught Mercedes testing the next-gen GLA in a more production-ready form (above), though still heavily camouflaged. It retains the general aesthetic of being a stylish crossover, but a sleeker roof gives the crossover an even more aerodynamic look. As an alternative, the new GLB-Class will reportedly be a more utilitarian compact CUV and will possibly borrow some of the styling cues from the G-Class.
Mercedes will reportedly have eight models on the MFA2 platform, and the first of them will arrive in 2018. Inside, they'll have the new Mercedes-Benz User Experience infotainment tech that the German automaker will unveil at the upcoming Consumer Electronics Show. Like the rest of the company's lineup, the compact models will also move to a two-tiered AMG lineup with a mild performance option and more extreme (more expensive) variant.
