According to the latest reports, the 2017 BMW X3 is currently in testing phase and it should be unveiled by the end of this year. X3 is currently one of the models that is selling good and it has grown in popularity over time, even though it was not so popular when it was first introduced. The newest model will be completely redesigned by Calvin Luk, an Australian currently working at BMW. Apart from the new design, reports that have started surfacing on the web suggest that the BMW X3 2017 is going to be lighter, smaller and bring lots of new features.
