Haas boss Guenther Steiner leaves F1 fans at Australian GP in stitches with brutal ‘your mum’ joke

FORMULA ONE team principal Guenther Steiner left fans in stitches after a brutal fan putdown.

Thanks to Netflix's Drive to Survive F1 series lifting a lid on the Italian, Haas team chief Steiner is known to be prone to angry tantrums as he much as he is a cheeky joke.

And during a Q&A session with fans ahead of the Australian Grand Prix, one young petrol head found himself on the receiving end of one of his jokes.

The young Aussie, named Noah, asked who was the better driver out of Haas duo Kevin Magnussen or Nico Hulkenberg.

Steiner then responded by saying: "Ask your mum.

"Who does she like better, you or your brother?"

The 57-year-old could not help but cast a wide grin after his comeback, with the crowd also left cheering and clapping the response.

Fans online were also quick to chip in.

One fan said: "They had to carry that kid off on a stretcher."

A second admitted: "I thought he was gonna end at ask your mum 🤣."

A third declared: "Guenther is a worldwide treasure!"

"Classic Gunther Steiner. Wouldn’t have it any other way," commented a fourth.

Another added: "GOAT."

Haas scored their first point of the season in last week's Saudi Arabia Grand Prix as Magnussen managed a P10 finish.

They will be hoping the Albert Park circuit in Melbourne will see both drivers earn points.

Further up the order, Lewis Hamilton and Co will be hoping to close the gap to the dominance of Red Bull's Max Verstappen and Sergio Perez.

They have secured one-two finishes in the two opening races of the season.

Verstappen dominated in Bahrain before Perez won around Saudi Arabia as Verstappen recovered from a P15 start position to finish P2.
