Mercedes' revised design gets a stylish steeply raked windscreen.

Mercedes-Benz has development underway on a major overhaul of its front-wheel drive lineup of compact models. New spy photos provide a fresh look at the work's progress on the next-gen B-Class.

This B-Class wears extensive camouflage, but the design suggests Mercedes is giving the new car a pointier nose and a more steeply raked windscreen. The changes give the hatchback a more stylish appearance. However, the model retains the existing large windows, which should mean plenty of room for packing people inside.

The new B-Class was spotted recently with nearly no disguise, which provided an even clearer look at the new design in profile (see gallery above).

Inside, there are fewer clear details available about the 2019 B-Class. However, the automotive world should get a better idea about the cabin in a few weeks because Mercedes plans to introduce a concept cabin for future compact cars at CES in Las Vegas on 9 January 2018. The firm calls it the Mercedes-Benz User Experience and promises the upgraded tech will feature an intuitive operating system thanks to the assistance of artificial intelligence.

The latest evolution of the MFA compact car platform from Mercedes will underpin a wide array of new and updated vehicles. The next generations of the A-, CLA-, B-, and GLA-Class will use it. Plus, the company is all set to add an A-Class saloon and GLB-Class SUV to the lineup.

When it comes to alternative-fuelled vehicles, the future of the B-Class Electric Drive appears less certain, though. Mercedes is giving the all-electric MPV the chop, and doesn't have a direct replacement in place. Instead, the company's forthcoming line of electric models that will sit under the EQ sub-brand seem the most likely candidates to take over this role.
