The relief felt across the Formula 1 paddock after the Chinese Grand Prix produced a better show than Australia was real, but so is the caveat.
Just like Melbourne highlighted the worst side of the new cars and power units, the Shanghai race worked because of a specific alignment of circuit layout and energy balance.
Replicating that at every venue on the calendar is a different challenge altogether, and one that Formula 1 will have to face one at a time unless the regulations are modified.
Suzuka this weekend will be another serious test whose results should hopefully go more in the China direction than the Australia one.
Shanghai’s racing was far more genuinely authentic than Melbourne’s, and what’s behind that is fairly clear to everyone who followed the weekend: It all came down to the sequencing of corners between overtaking zones.
In Shanghai, the cars were effectively empty of battery charge well before they reached the braking area at Turns 10 and 14. Energy had been spent in the middle of the straight, where any power differential between two dicing cars is largely irrelevant.
By the time they arrived at the point where an overtake could actually be made, the playing field was level.

And so what followed was a conventional outbraking battle decided far more by driver skill and car placement than by battery power, as was the case in Australia.
Suzuka’s layout presents a fundamentally different set of variables, and they compound on each other in ways that are still difficult to predict in advance.
The Japanese track is a faster, more flowing circuit than either Melbourne or Shanghai — less energy-hungry through its middle sector, with fewer of the tight, low-speed corners that allow aggressive regeneration between overtaking zones.
That means less opportunity to replenish battery charge between the moments where racing actually happens, and so the margins are tighter.
Is 130R ruined?
One of the most iconic and demanding corners in Formula 1, Suzuka’s 130R will be the most immediate concern for teams and, sadly, also for drivers and fans.
In a formula where battery state at any given point on the lap is this consequential, a high-speed corner positioned immediately ahead of a demanding acceleration zone like the final chicane creates an obvious dilemma.
Energy reserved for 130R is energy unavailable for the chicane, and energy spent at the chicane is energy absent on the pit straight.
In a conventional formula, that is a tyre and fuel management question, but in 2026, it becomes a more complex issue.
The end result is likely to be that 130R will no longer be a demanding corner.
As veteran F1 journalist Mark Hughes put it in last week’s Motor Sport Show podcast, “The obvious candidate is 130R, because they want to be able to have the energy to accelerate up to the chicane and not run out of battery, or the chicane where there might be dicing and also to have it down the pit straight.”
If a driver has to manage battery state through 130R to ensure they have enough charge for what follows, the laptime and the spectacle are both likely to suffer, as Fernando Alonso explained ahead of the Chinese GP.
“We used to fight for our life in Turn 12 in Bahrain, Turn 9 and 10, Turn 11 in Melbourne, Sector 1 in Suzuka, 130R, Turn 7, Turn 8 here in China,” the two-time champion said.
“There were always certain corners that in Formula 1 were challenging the limits of the physics going through those corners, and the driver had to use all the skills and be brave in some of the moments as well.
“When you put new tyres and you go through the corner at the speed that you’ve never been before in any of the free practices, that challenge is gone in a way. You use those corners to charge the battery, not anymore to make the laptime.”
The Melbourne spectacle was tough to digest, but Shanghai exposed an upside to Formula 1’s new rules, showing that the series can deliver racing that’s thrilling and skilful, as Mark Hughes explains

The qualifying picture at Suzuka may be the starkest illustration of this. With a flying lap demanding maximum commitment at every corner, the energy trade-offs become acute.
Whether the race itself reproduces the specific Melbourne problem — cars arriving at an overtaking zone with divergent energy levels, turning what should be a contest into a foregone conclusion — remains to be seen.
However, the different energy demands of the Suzuka layout point towards more balanced racing, like seen in China.
The equation Formula 1 needs to solve — how to match energy limits to circuit characteristics so that racing is both entertaining and genuine — is complicated enough that a wider sample of tracks will produce a more reliable answer than an early intervention based on two data points.
What Shanghai established is that the equation is solvable and that the 2026 rules are not inherently broken. Calibration can be refined.
Suzuka is a harder circuit to crack than Shanghai, and the first attempt at any new problem rarely produces a perfect answer, but it will tell F1 something important: either that Shanghai’s lesson can be applied elsewhere, or that the work of figuring out how to do so is more complex and more urgent than it currently appears. Either way, the data will be useful.
