Toyota's re-entry into the World Rally Championship next year is expected to be a development year for both the new Yaris WRC and the yet-to-be-announced drivers.
Team boss Tommi Makinen is still to confirm his driver combination but admits the likes of youngsters Ott Tanak, Elfyn Evans, Teemu Suninen, Esapekka Lappi and Pontus Tidemand were on the radar.
"Basically there are some of the current drivers available, not too many of them, but there are also pretty experienced young drivers, promising newcomers," Makinen told wrc.com.
"I would say we need to make up our mind how we want to think about the future. Do we look more for 2017 and try to be as ready as possible then, or are we looking a little bit further to the future?
"We need to look what is our direction and that's a decision we will do with Japan.
"Of course, we would like to see ourselves as soon as possible on the podium but at the same time we need to be realistic where we are.
