Hamilton aces practice but accepts grid penalty
Lewis Hamilton led the way in both Friday practice sessions ahead of this weekend’s Turkish Grand Prix, but will begin Sunday's race with a 10-place grid penalty.
Mercedes incurred the sanction by taking on a fourth engine - one more than competition rules allow for - and Hamilton is 11/4 to take the chequered flag on Sunday.
However, their use of only one internal combustion engine prevents a full drop to the back of the grid, such as that enforced on Max Verstappen's Red Bull last time out.
