Here's something curious. As you may know, most car manufacturers have web pages specifically designed for a certain country, and these pages are managed by different people. Occasionally something goes wrong and a new model or a facelift ends up getting revealed through one of these websites. This is what happened with the Swift and Sukuzi's Belgium page.
The changes are very small, it now features the mandatory LED day running lights next to the fog lights and the side turn signals were moved to the side mirrors. The interior doesn't look like it at any changes made to it.
From what i can see in Sukuzi's Belgium website, the engines options will also remain the same. Presentation should take place at the 2013 Frankfurt Motor Show in September, with sales starting in early 2014.
