Hoods or drops when in the draft?

It makes a lot of sense that being in the drops on your road bike is more aero than being on the hoods. But is that also true when riding in the draft?

Specialized invited the 2014 ITU World Champion Gwen Jorgensen to their WinTunnel in Morgan Hills, California to test that very situation. Under the guidance of aerodynamics engineer Chris Yu they went to work and the result was surprising.

Chris Yu goes over the date with Gwen Jorgensen after the test and it sounds like Gwen will adjust her position, or at the very least be more aware.
