Model years

Hi. I’ve ordered a new se tech and looking through the paperwork it says 2015. Can someone explain to me why it says that when it’s new. Is there a newer version and if so what are the differences? Thanks

Think we'd need a bit more info on what paperwork says that, could it just be an old printed document, or is it specifically referring to your vehicle,

2015-2016 is quite a big change, (Engine, bodywork, Lights etc)
