The fourth season of "Drive to Survive," the Netflix docu-series that has turbocharged Formula One for new and younger audiences, debuts on Friday with the sport still committed to the "marriage" despite controversy and criticism.

The 10 new episodes offer behind the scenes insight into the 2021 season, one of grand prix racing's most exciting and closely-fought championships.

"I think it's a great partnership," Greg Maffei, CEO of Formula One's U.S.-based owners Liberty Media, told analysts in a recent conference call.
