DTM championship runner-up Edoardo Mortara will join the Mercedes line-up in 2017, the German manufacturer has announced.
Italian Mortara, 29, has raced for Audi since his DTM debut in 2011, scoring eight wins during his six-year tenure with the Ingolstadt marque.
He had long established himself as a championship frontrunner and was Audi's main challenger in the 2016 drivers' title battle, losing out to BMW's Marco Wittmann by four points.
"We are delighted to finally announce Edoardo Mortara as one of the team's race drivers for 2017," said Mercedes DTM boss Ulrich Fritz.
"Edoardo and Mercedes-AMG came to an agreement for some time but due to respect to our colleagues at Audi, we didn't announce the signing of their title contender earlier.
"Edo is a perfect fit for our team, as he's not only an experienced race driver but also a great character. We're definitely looking forward to a successful partnership with him."
Mortara's arrival leaves only five spots in the Mercedes line-up for its eight current drivers - none of whom are yet to confirm their plans for 2017 - after DTM manufacturers announced a switch to six-car line-ups.
HWA will run all six Mercedes drivers next year, with the Mucke and ART squads bowing out of the series.
