Mercedes has kicked off the teaser campaign for the 2020 GLA. Set to be unveiled on December 11th, the redesigned crossover will be larger and more luxurious than its predecessor.

The company is keeping details under wraps, but they released a digital countdown clock that shows the GLA in the background. The image isn’t very revealing, however it confirms the model will have a new greenhouse with a third quarter window. That’s a change for the GLA and it should help the model look more like a crossover and less like a lifted hatchback.
