Christian Horner snapped back at Frederic Vasseur after the Ferrari chief doubled down on his belief that Red Bull had got away with their budget cap breach with a "very light" punishment.
Their overspend in the 2021 season resulted in a £6m fine and a 10 percent reduction in their wind tunnel time over a 12-month period. The financial penalty is a drop in the ocean considering the financial power at Red Bull's disposal, but the sporting sanction promised to be more significant.
After all, because they won the constructors' championship last year, they were already going to have less time in the wind tunnel than everyone else. So a further reduction gives the other teams a significant advantage when it comes to car development.
