Max Verstappen has apologised for his "heat of the moment" rant after he was forced to retire at the Hungarian Grand Prix.

The Red Bull driver experienced a loss of power from fifth position and let loose over the team radio in an expletive-laden outburst. But, while the 20-year-old is still frustrated, he acknowledged that he should not have reacted in such a manner.

Verstappen's Hungaroring woes, which came a week after teammate Daniel Ricciardo retired from the German Grand Prix with mechanical trouble, prompted Red Bull team principal Christian Horner to question the efforts of engine providers Renault.

Renault Sport F1 boss Cyril Abiteboul responded by telling : "Our bosses have stopped reading what Christian Horner is saying about us since 2015."

Red Bull is to enter a new partnership with Honda after the end of the 2018 season. Verstappen heads into the mid-season break sixth in the Formula One drivers' standings.
