Listen as a frustrated Sebastian Vettel blasted the driveability of his Ferrari after only qualifying fourth for the Belgian Grand Prix.
The German took to the team radio to declare that without even pushing the car had "no grip" and "lost traction" at the final chicane.
Vettel felt the issue cost him "easily one and a half tenths just on power" which would have seen him challenge Max Verstappen for a front row slot on the grid.
The result means that Vettel will start behind team-mate Kimi Raikkonen for the third time in four races.
The outburst is the latest in a serious of aggravated radio messages as pressure grows on Ferrari to deliver better results from senior management.
