IndyCar's two main championship contenders Will Power and Scott Dixon are among the six drivers who will have to overcome 10-place grid penalties at this weekend's Milwaukee round. Power (Penske) and Dixon (Ganassi) will both be required to make unauthorised engine changes for the Milwaukee race after suffering engine failures during testing at Iowa yesterday.
