Schumacher will receive a five-place penalty for changing the unit, as drivers are required to use the same gearbox for five consecutive races.
He will share row 11 of the grid with Pastor Maldonado, who also has a gearbox change penalty.
Meanwhile Jean-Eric Vergne will not receive a penalty for missing the weighbridge during yesterday’s qualifying session after the stewards chose to issue a reprimand.
