Netflix's dramatic F1 documentary 'Drive to Survive' is back. Here are the 5 biggest talking points from the new series.

Last week, Russian driver Mazepin was dropped by Haas following his country's invasion of Ukraine.

Prior to losing his seat thanks to global sanctions against Russia, however, the 23-year-old's F1 career was already in jeopardy.

Despite being a two-time F2 winner, Mazepin struggled to adapt to the big league, crashing out in five races during the 2021 season and finishing joint bottom of the driver's championship having failed to score a single point.

Amid his struggles, Mazepin's father, Dmitry, who is the chair of Haas' main sponsor for last season, Uralkali, threatened to pull his sponsorship of the team unless it could find a way to improve his son's performances.

He didn't, but Haas team principal Guenther Steiner was not happy with the threat.

Healthy competition between drivers on the same team in F1 is generally seen as a good thing.

But in the case of McClaren duo Lando Norris and Daniel Ricciardo, things went a bit too far during the 2021 season.

Norris reveled in Ricciardo's early struggles on the team and seemingly took issue with the Italian-Australian's confident personality, mocking him behind his back on numerous occasions.

Fortunately for McClaren, after Norris was called out about his attitude toward Ricciardo, things came good between the pair at the Italian Grand Prix.

After Lewis Hamilton and Max Verstappen crashed out, Ricciardo and Norris teamed up to take first and second position respectively before celebrating victory together with champagne and smiles.

With Hamilton having won six of the last seven driver's championships and Mercedes winning all of the last eight constructor's championships going into the 2021 season, the rest of the grid was ready for a change — nobody more so than Red Bull team principal Christian Horner.

"Fuck it, got to keep the smile of his face," Horner said of Mercedes boss Toto Wolff after Max Verstappen beat Hamilton in qualifying for the season opener in Bahrain.

When Hamilton eventually won the race, Horner said: "Fucking Mercedes."

Max Verstappen does not make a single appearance sat in front of the camera during the entire of season four, despite the series' arc focusing on his and Hamilton's title race.

Verstappen refused to take part in filming for the show, citing concerns about the documentary's producers creating false narratives around him and his rivals.

"I understand that it needs to be done to boost the popularity in America," the Dutchman told the Associated Press about his absence from the show. "But from my side as a driver, I don't like being part of it.

"They faked a few rivalries which they don't really exist. So I decided to not be a part of it and did not give any more interviews after that because then there is nothing you can show."

In the absence of Verstappen and with limited appearances from big stars such as Fernando Alonso and Sebastian Vettel, it's the young drivers who steal the show in season four.

The aforementioned Norris shows himself to be focused and full of ambition, albeit very cocky at times.

AlphaTauri's young Japanese racer Yuki Tsunoda is in equal parts hilarious and incredibly talented, proven by his multiple top 10 finishes throughout the campaign.

The charming George Russell proves why Mercedes were keen to see him partner Lewis Hamilton for the 2022 season, while Ferrari duo Charles Leclerc and Carlos Sainz Jr. show, both on and off the track, why they will be a partnership that others will fear in the coming years.

The future is bright for both F1 and Drive to Survive.
