Mercedes-Benz's smallest offering will be all-new in the near future after our spies managed to photograph the next-generation A-Class being tested in Europe.

Even with the heavy camouflage, the prototype 2018 A-Class gets exterior tweaks which can be seen up front and at the rear. The front fascia still gets Mercedes-Benz's signature headlight design but the front grill takes on a different shape. Even more apparent is the unconventional hood though that could have been used to throw off spies.

Along the side, it appears the 2018 A-Class will have a longer wheelbase than the current generation. This is highlighted by what looks to be a covered-up rear quarter window which the current model lacks. This will allow for better space for the rear passengers. Meanwhile, the rear section also gets the heavy camo treatment but the rear bumper and tailgate appeared to have been slightly tweaked.

It is expected that the new A-Class will be sitting on an improved version of the MFA platform called MFA2. Aside from being lighter, the MFA2 platform will be able to handle a plethora of powertrains and drivetrains. In addition, the new chassis will also be used in the next-generation B-Class, CLA-Class and a smaller crossover which will apparently be called the GLB.

There will be two body styles available for the upcoming A-Class, a 5-door hatchback and a 4-door sedan which will likely be only available for the Chinese market.

In terms of engines, the 2018 A-Class will still be driven by a wide array of four-cylinder gasoline- and diesel-powered engines. AMG versions are also expected to be carried over, particularly the A40 AMG with more than 300 PS and the A45 AMG with over 400 PS.
