Each car’s front and rear wings are now active, with a raised position called corner mode that generates lots of downforce, and corner mode, which drops both wings to minimize drag
I am guessing that they aren't both called "corner mode". :sneaky:

is paired with a 4 Mj (1.1 kWh) battery pack
Cars are allowed to deploy up to 8.5 mJ (2.4 kWh) of electrical energy per lap
Maybe dumb question, but how can the car deploy more than double the battery capacity? Does it recharge fully within a lap?

Also, the units should be "MJ" in both instances.

Yes, they can recharge at least twice during a lap, either from braking or using spare energy from the V6.

I’m pretty sure the unbelievable reliability that’s been a feature of F1 for the last few seasons may be a thing of the past, at least for the first few races in 2026. Up and down the pit lane, teams have missed hours of practice sessions as they troubleshoot gremlins. Aston Martin looks particularly bad in this regard, even in comparison to brand-new Cadillac.

I've been wondering about that, too. Over the years, the teams have learnt how to build bullet-proof cars. Certainly, they won't have unlearned that? Of course, they will push hard and maybe cross some material limits. But one hopes that the reliability remains high (I still remember how in the 1990s half of the field could be wiped out because of aging Cosworths, fragile suspension systems, and the occasional brake disc on fire).

the MGU-K won’t be used at race starts—it only begins to contribute above 50 km/h (31 mph). That’s to prevent the danger of some drivers depleting their batteries and therefore slowing much faster than others in the approach to the first or second corner at the start as they superclip
I could use the longer explanation for this.
First, they certainly hit 50km/h long before the first turn (before they cross the line for all but the front lines). Second, if they all do it, or avoid doing it, because of the benefit or disadvantage, what's the specific danger ? Third, when running as a pack and trying to dodge the first-turn-3-wide traffic, is maximum braking capability really that big of a factor?
Please, O greatest of internet comment boards, ELI5.

I was following F1, but I don't use apple TV nor will I
the forced into is bs also annoys me.

I don't think it's going to be that exciting because they basically capped energy use per lap.
with 50% max from engine and 50% from battery it's set how much you can use. If everyone uses it at the same time, they should all maintain about the same speed. Woo. fun
that's not exciting racing that's just whomever can do math better.
I'm not sure where you are located, but if you sub Apple TV you can still sign in through the F1TV app like before. You never actually have to use Apple TV.

On the topic of the racing, I have my concerns too. I've watched most of the televised preseason testing and there are certainly gremlins with some teams, but the PUs are very very reliable thus far. AM has gearbox issues and the Honda PU is likely not going to cut it, but that's speculation.

The battery usage isn't quite as straightforward as you are making it, but some drivers have come out and said that overtaking has been tricky. There's been limited opportunities for "racing" in testing though so I'll just reserve judgement for now.

Ferrari tested an interesting approach to this in Bahrain at one point, with rear wing elements that flipped a full 180 degrees. I wonder if we’ll see that in-season.

It looks wild as hell. I thought they said that they'd use it for the Australia GP at least? Really interesting development. It actually generates lift vs only reducing drag. Will be fascinating to see how it performs in the straights vs others.

And I'm looking forward to the chaos of the new revving procedures without the MGH-U to reduce turbo lag. All the cars need a good 10-20 seconds of revving prior to launch. Will be interesting to hear what that sounds like...

Bacon Briefcase? WTF does that mean

Regardless, I know how I'd cheat. With the sustainable fuels, I'd make slowly dissolving fuel lines that add energy to my fuel. Maybe not so slowly dissolving for qualifying. The fuels are going to be a huge part of the competitive balance this year.
They still have the flow regulators that measure fuel injection though. But I do like your creative problem solving...

I've seen it said in places that the movable front element does very little to change drag. Moving it does reduce the amount of downforce. Now, I don't completely understand all the losses that additional downforce is creating, but a few engineers seemed quick to point out that while the rear wing does produce a ton of drag, the front elements generally do not, so the active elements are accomplishing slightly different things on each end.

The thing about the front wing is, even when it's down...there's still the core body and side pods right behind it, so it's not eliminating that much drag overall. Just changing how the air flows around everything. A few teams seem to be trying some different sidepod configurations, Idk if it's related to the front wing aero or not though.

No mention of Ferraris rear wing? Everyone is getting very excited over that....

Edit; poor use of words.
You missed this bit: " Ferrari tested an interesting approach to this in Bahrain at one point, with rear wing elements that flipped a full 180 degrees. I wonder if we’ll see that in-season."

I'm mostly curious about the engine shenanigans Merc and RB are supposedly pulling, with combustion ratios increasing while hot. Playing games with CTEs almost always leads to unexpected failures in my experience, so I'd love to get more details about what they're doing, or if the FiA treats it seriously enough to modify the testing rules as they've been discussing.

The front wing shapes the air in front of the tires.
The shape required for maximum downforce at 100MPH in a turn may cause the wrong kind of turbulence in front of the tire/body at 200MPH in a straight. If you can separately shape the air for the straight, instead of having to go for one-size-fit-all, then you could reduce the tire/body drag in the straight. When milliseconds matter...

Likely a change coming after 13 races and then components will be measured at 130C.

Also going back to the start procedure/long revving to offset turbo lag, Ferrari brought this up as a concern last year and it was dismissed. Now all the other teams want to change start up procedures. Meanwhile Ferrari off the start is: https://streamain.com/en/03U0Aisp9RzTXTJ/watch and https://packaged-media.redd.it/081t...00&s=ec1b21ff1d8d8903d3e57a16ce18f25d901a3569

Ferrari doesn't want to change now, because they might have been the only engine manufacturer to really think through the turbo lag issue during design...

There is a video on the official F1 channel (done by the Tech Talk guy) where he monitors a bunch of practice starts from the pit lane. With the MGH-K no longer muffling the exhaust, it's 5-20 seconds of absolute HOWLING noise before the start. If you're going to an event, you're gonna want to wear earplugs for the start if you're in the home stand!

The really interesting thing I'm seeing in testing is the insane number of lockups everyone is having. Seems to have to do with switching the active aero into corner mode (possibly changing the load balance). Some teams seem to be getting on top of it, some are not -- Aston and Racing Bulls look to be squaring off tires like nobody's business still. The fun part is that it affects and is affected by everything -- your aero, your actuation of your active aero, your suspension, your brake balance, on and on and on.

Everyone is super-excited for these new regulations, but let's be real -- the first few races are likely to be hilariously uninteresting, because the disparity in the field is going to be massive. Expect one or two manufacturers to walk away from everyone else within a half dozen laps.

Or maybe not; the tradeoffs and design decisions may make for much more interesting racing; Red Bull seems to be fastest on the straights, McLaren and Mercedes seem to be better in corners... and with the deployment of electric power not necessarily having an "optimal" that works for every engine manufacturer, it'll be an interesting race to see who can copy each other's best innovations best and fastest.

Ah, found the video. It's never going to sound like the V10s of old, but I'm really digging the noise:

Everybody would, but nobody's talking. There's no dynamic adjustment or chip thing you can do to change it, right? There has to be something in there designed to expand in a controlled fashion to get this done. As a RB homer, I don't necessarily want this to be banned and exposed afterwards -- but as a nerd, I am dying to know at the same time.

Little wonder Stella/Mercedes teams were bringing up the "safety issue" with starts.

Really looking forward to going to the Melbourne qualifier day in a couple of weeks. It’s going to be super interesting

Race day will be party at my apartment. Might even be able to hear the engines from my place

As for the reg changes? I’m very much a fan of change and hoping for some racing/driver innovation. We shall see

Go Oscar and Liam. Downunder represent

F1 race day will not improve until at least one of the following is adopted.

1. Get rid of qualifying and adopt a reverse grid start based on the current season leader board. Why was giving extra advantages to the fastest racers ever a good idea?

2. Get rid of aero. Real racing means cars, gasp, get close. Would anyone notice or care that top speeds are 180 mph instead of 220 mph? Didn't think so.
1. Eliminating quali would take whatever fun there was out of tracks like Monaco. Plus, it's interesting to see which teams aim to do well in qualifying and hold onto their position during the race, versus optimize for the race and hope to survive quali.

2. There are plenty of other series to watch if that's what you're into. NASCAR, sports cars, etc... F1 has been about making the best upside-down airplane for over 50 of its 75 years now. The on track action has never been as unpredictable as the various spec. series you could support instead.

The honest drivers are not, and so are some of the better F1 journalists. If you listen to some of the driver comments, they all tell you the cars are less fun to drive


Lewis Hamilton says they're fun: “The car generation is actually a little bit more fun to drive – it’s oversteery, it’s snappy and sliding, but it’s a little bit easier to catch and I would definitely say more enjoyable.”

Lando Norris says they're fun: “They’re good fun, because it’s more power and less grip to a certain extent,” said Norris. “Which means you’re hustling, you’re having to control the car a bit more, fight the car at times more.”

George Russell like the power and the fact they're more nimble:
“I think for all the cars I was watching today, with all the different power units, it’s probably the quickest I’ve ever seen an F1 car pass here in Barcelona, so that was pretty exciting to see. And the cars, you feel it being smaller, you can feel that weight reduction compared to previous years, so I think from that aspect as well it’s gone in a good direction.”

Kimi Antonelli says they're fun to drive:
“It’s fun to drive,” the Italian reflected. “Obviously the car being a bit smaller, you feel it – it’s more agile, especially in changes of direction and in slow-speed corners which is a nice feeling, plus we don’t have bouncing anymore which is another good thing, so you don’t have to run the car as low and you have a bit more room to play with ride heights. You have a bit more room to play with the set-up, to play with the car, which is super nice and super interesting as well as a driver, to also understand what compromises you can find set-up-wise.”

And Bearman: “It’s good fun. It’s my first time being in this situation with a regulation change where, as drivers, we can have so much impact on the end result, so it’s a great prospect.”

A lot of commentators have attributed some of this to a couple elements of the hybrid system. First, variation in how much electric power a car is deploying or regenerating on the straight before a big braking zone means that cars are approaching the corners at a much wider range of speeds than the previous generation. The drivers seem to still be getting used to how this affects the braking point.

Second, the state of the battery can affect how much deceleration is being done with regen versus the brake discs. If the battery is full up the car has to rely on the brakes, which is going to affect the brake balance.

Before the season there was a bunch of talk about how managing energy deployment was going to add to drivers’ workloads. It’s looking like there are a bunch of second order effects that the drivers will have to learn to manage as well.

Verstappen has another take.

The Dutchman did not pull any punches when asked what he thought about the 2026 F1 cars, saying it felt like he was driving in Formula E.

Facing the media in Bahrain on the first day of the final preseason test, he claimed he was not the only driver with a negative view on the new rules, saying: "“Most of them think the same way.”

The likes of Lando Norris and George Russell do not agree with the Dutchman, so when it was suggested to him that two camps are emerging, he quipped: "That one camp is more like a small easy-up tent; the rest are in a very big tent. So it’s one small camp and one big camp!

“I might be a bit more extreme in how I say it, but that’s also because I don’t really care that much [about what others think]. Some people are a bit more diplomatic," he explained.

Really? Lift to reduce friction (and increase speed without increasing power) without being catapulted? I got that image, I sure hope it is not that dramatic ;) A lot of these discussions make me jealous of the people who actually try to redefine such limits - engineering at the very top!
