McLaren junior Nyck de Vries and FIA WEC regular Loic Duval are among the four drivers named by Audi in its line-up for the DTM rookie test at Jerez.
The duo will pilot the Audi RS5 DTM alongside GT drivers Kelvin van der Linde and Dion von Moltke over the course of the test, which is scheduled for November 29 - December 2.
Duval, 34, has been part of Audi's prototype racing line-up since 2012, winning the WEC title and the Le Mans 24 Hours race in 2013.
The Frenchman was part of Audi's WEC line-up in the marque's final season in the series, but is not currently unemployed as he also races for Dragon in Formula E.
De Vries, 21, is a long-time McLaren protege, a champion of Formula Renault 2.0 categories Eurocup and Alps and a race winner in both Formula Renault 3.5 and GP3. The Dutchman is currently sixth in the GP3 standings.
Van der Linde, 20, is the 2013 Volkswagen Scirocco R-Cup champion and the 2014 ADAC GT Masters champion in partnership with Audi factory driver Rene Rast.
Von Moltke, 26, represents Audi's customer programmes on the American endurance racing scene, with wins and podiums across various US-based championships.
Audi DTM regulars Jamie Green and Mattias Ekstrom will be present at Jerez with a "prototype" version of the 2017 car, while Green and Rast will serve as reference drivers for the newcomers.
