Briton Mike Conway and Japanese Formula 3 champion Marcus Ericsson will join Mercedes Grand Prix for the young driver test days at Jerez.
IndyCar Series racer Conway was a test driver for the outfit when it was owned by Honda in 2007 and 2008, and is scheduled to run on all three days of the test that is restricted to drivers without vast race experience. Ericsson impressed with his campaign in Japan this year, and his year ended strongly when he took pole position for the Macau GP qualification race last weekend.
The test takes place at the Spanish track from December 1-3. America's J.R. Hildebrand is also set to test at Jerez for the Force India team.
