Why would you want to get it tested? Why not just wait for the EPA to test another 2015? I'm not sure what information benefit you'd get from commissioning your own test that would offset the time and money it would take to execute such a test.
That's why I'd like to get it tested. I think they may have gone with the 2016 since that's what is currently on the lot, but I am very skeptical it is new to the 2016 model year when the required standards and engine did not change.
