AFAIK, the 2016 models are a direct carry over from 2015 with no changes. Note: this is 'v' specific.. obviously the 2016 gen 4 prius lift back is quite different from the 2015 gen 3 prius liftback.
No changes in 2016, based on checking the 2016 Prius v brochure at the dealer, while waiting for our 6 mo./5000 mi. 2015 Prius v maintenance. Most Toyota models had 2016 brochures, but no 2016 Prius gen 4 brochures or models on the floor!
