Rosberg, Webber, could face engine penalty
The rookie German's team is reportedly considering changing his Cosworth engine ahead of schedule, according to German magazine Auto Motor Und Sport.
''(Cosworth) fears that the eight cylinder'' will not make it through another race, the news report explained, adding that the problem might involve damaged piston rods.
20-year-old Rosberg's engine failed in Malaysia, and the Imola-spec engine belonging to teammate Mark Webber may also have shown signs of damage.
Technical director Sam Michael suggested that the Nurburgring's 'crazy' weather might make a qualifying penalty easier to handle.
''So a bad starting position is perhaps not so bad,'' the Australian said.
It is unknown how long the basic technical flaw will take to fix, but boss Alex Hitzinger said Cosworth has 'neither the money or the personnel' to react as quickly as its rivals.
