F1 engine clampdown to hit Red Bull

Technical boss says new rule could bring his leading team back to field

MILTON KEYNES, England - Red Bull could be hit more than rivals Ferrari and McLaren by Formula One's clampdown on engine mapping and exhaust systems, the champions' technical head Adrian Newey said on Tuesday.

The governing International Automobile Federation (FIA) has told teams to adhere to a fresh interpretation of the rules from this weekend's British Grand Prix at Silverstone.
