Max Verstappen was just 12km away from an engine failure which would have ruined his race at the Hungarian Grand Prix, according to Christian Horner.
The Dutchman started from 10th place after having his qualifying ruined by a small issue in his power unit. To give them the best chance of weaving through the pack, Red Bull decided to give him and team-mate Sergio Perez fresh power units.
And it turned out to be an inspired call for more than one reason. No doubt Verstappen benefitted from the extra horsepower, but Horner has revealed that without the new engine the Dutchman would most likely have not even been able to start the race.
