Yes, the current generation Tiagra (4700, 2016 model year) is modeled after the 11 speed groupsets (5800, 6800), including the new shaped hoods and internal cable routing. That being said, the previous generation Tiagra (4600) is a solid groupset as well, I've used it for years on my Giant Defy and functionally it works great.
