Undisguised, because it's a mule.
McLaren's publicity campaign for the upcoming 675 LT has been a bit odd, including as it does the occasional posting of spy shots of its own car onto its own social media accounts. But before the car is officially unveiled in Geneva next month, we have some more traditional (and exclusive) spy footage of the car, shot outside the company's UK factory.
The car is undisguised, no camo or anything, which is a pretty sure sign that this isn't how the finished product will look. Hat tip to Marcus for this video.
