For 2012, the team removed the "GP" from their name and added the name of AMG, the high performance brand of Daimler AG, to their title. The team would officially get the designation "Mercedes AMG Petronas F1 Team". At the start of the season Mercedes was the subject of protest over the use of a "radical" rear wing concept on the Mercedes F1 W03 racing car, which was not settled until the third race in China when the stewards unanimously rejected the protest. At the third race of the season in China, Rosberg took the team's first pole position as a works team since Fangio in ; Schumacher finished the session third, but moved up to second after a grid penalty for McLaren team's Lewis Hamilton. The team secured its first win in 57 years when Nico Rosberg finished first in the 2012 Chinese Grand Prix. In addition to that, Rosberg became the first German driver to win a Grand Prix driving a German vehicle since Hermann Lang's victory at the 1939 Swiss Grand Prix. On 28 September 2012, it was announced that McLaren driver Lewis Hamilton would join the Mercedes team from the season onwards, having signed a three-year deal to partner Nico Rosberg in the team. In January 2013, Toto Wolff became an executive director of the Mercedes AMG Petronas Formula One Team, with his business partner Rene Berger becoming non-executive director. In addition to joining the team as managing partner, he also acquired 30% of Mercedes-Benz Grand Prix Ltd, with a further 10% held by Niki Lauda, chairman of the board, and 60% by the parent company.
