Mansell: FIA clampdown to be intriguing

Nigel Mansell thinks the debut this weekend of the full FIA clampdown on off-throttle engine exhaust blowing will be "intriguing".

"It is going to be very intriguing to see who is affected the most, and who can move ahead on the grid," the 1991 and 1992 Silverstone winner, who will be the driver steward this weekend, said.
