Could This Pagani Huayra Test Mule Be The Huayra S?

This picture was recently taken which shows a Pagani Huayra dressed up in camo. The Huayra has been for sale for a few years now so this must be a new model undergoing testing. The exhausts look different to the ones we have seen on the existing cars and those bright green calipers may be hinting at a higher-performance edition. We are expecting the Huayra S model so this could well be the first mule spotted testing. I cannot see any other visual modifications at this stage but hopefully we get to see some more pictures of the new car in the near future.
