From the spy shots, it doesn't look like there are any dramatic changes. It's a popular car and a low price point for MB. Will be interested to see what it looks like when completed.

The Mercedes-Benz CLA-Class only arrived on these shores in 2013, but it's already approaching the midway point in its life cycle at which point the popular compact sedan will receive a subtle facelift. The changes will mirror those made to the related A-Class hatchback earlier this year.

A prototype for the updated CLA has just been spotted. The car is expected to go on sale in the fall of 2016, as a 2017 model. Most of the changes will be cosmetic, as the 2016 model year already sees the CLA receive some mechanical upgrades.
