Ferrari’s front wing has been causing a stir in India.
The team has recently been experimenting at the front of its current car ahead of the 2012 season, but it was at the Buddh circuit that heads really began to turn.
A wing fitted to Felipe Massa’s car has been seen violently oscillating and flexing towards the ground at high speed, attracting the attention of FIA technical boss Jo Bauer.
"I can’t see how the FIA is going to be satisfied with this situation," said BBC pit reporter Ted Kravitz during the radio coverage of Saturday morning’s practice session.
"It is the amount of flex, not the sparks, that will raise the suspicions of other teams."
