We're still hiding a little bit: Mercedes boss on F1 pre-season

Mercedes Team Principal Toto Wolff played down his team's reported struggles on the second day of the F1 pre-season test. "The car is out of balance this morning...They (Red Bull and Ferrari) are fast. No surprise there...We're still hiding a little bit," said Wolff. Lewis Hamilton's fastest lap on the yellow-walled soft tire was a second slower than the Ferrari.
