The sixth season of Drive to Survive, Netflix’s blockbuster behind-the-scenes sportumentary, went live today. This isn’t a review of that. Instead, for the past few days my attention has been turned to Formula 1’s preseason testing, which got underway on Wednesday morning at the Bahrain International Circuit in Bahrain.

In the olden days, preseason testing was a thing you’d read about in the specialty press—a reason to buy a copy of Autosport in February, if you will. There was a lot more of it back then, too; up to five official preseason tests, although it was unusual for a team to attend all of them.

In F1’s current era, there isn’t really time for so much testing, even if it weren’t strictly limited by the rules. The first race of what should be a 24-race calendar takes place next Saturday (March 2), with the final round, also in the Middle East, not scheduled until December 8. Contrast that with the early 2000s, when a season might run for 16 or 17 races between early March and mid-October.

Back then, none of the preseason testing would be broadcast to fans, either. Now, thanks to F1’s streaming platform, there are 24 hours of coverage to keep you occupied, with each eight-hour day covered by an English-language commentary team that combines some of F1’s own (yay, Sam Collins!) with some voices more familiar to Sky’s (and therefore ESPN’s) coverage, like the always-excellent Anthony Davidson.

While I imagine the committed F1 fan will also add in all 10 hours of DtS season six, you’re unlikely to get nearly as good of a technical insight into the new cars or come away with a better understanding of what the drivers are doing in the cars to extract such speed so consistently.

Don’t read much into the times

An important thing to know about preseason testing is that it’s very difficult to read much into any of the lap times. The cars aren’t subject to scrutineering checks the way they are during a race weekend, and some teams aren’t above putting together a so-called glory lap to top the timesheets and maybe attract a sponsor or two.

These days, that’s far less likely than sandbagging—intentionally driving a car slowly at certain points during a lap, perhaps—to hide one’s true pace. Instead, each team has its own run plan designed to satisfy the needs of the engineers.

Rarer still is the team that shows up with something revolutionary that blows everyone else into the weeds. But it does happen—check out Keanu Reeves’ Brawn: The Impossible F1 Story for a 21st-century example of such a sporting fairytale.

What’s changed in the offseason?

There have been no real changes to the technical regulations for this year, but every team has a new car that reflects their better understanding of how the current ruleset needs to be best exploited.

The key to generating useful aerodynamic downforce from a current F1 car’s ground effect is to keep the car as stable as possible under both braking and accelerating, which means controlling dive at the front axle and countering lift at the rear axle. For 2024, some teams have had a fundamental rethink of how they do that.

Kick Sauber and RB (yes, those are real names) are joining Red Bull and McLaren in using pullrods (instead of pushrods) for their front suspension. Meanwhile, Mercedes, Aston Martin, and Williams have switched to rear pushrods, which interfere less with the underbody aerodynamics, leaving just Ferrari and their client Haas sticking with rear pullrods.

The floor might generate more of the downforce now, but that doesn’t mean bodywork isn’t important. Red Bull’s looks significantly different, incorporating ideas tried with varying success at other teams like Ferrari’s “bathtub sidepod” or Mercedes’ “zero sidepod.”

Truthfully, the most immediately noticeable difference from last year has been more teams opting to forgo a full-body paint job, preferring large expanses of bare carbon fiber in the name of saving another kilo or two. And if you’re looking for nerd trivia to bore impress someone with, the Mercedes drivers now have a WhatsApp button on their steering wheel to use to radio back to the pits.
