Reaction to Japanese GP practice
About this episode
Suzuka practice sparks debate as the FIA cuts qualifying battery recharge from 9MJ to 8MJ, but the super-clipping problem still looks severe—especially at 130R, where cars lose huge speed and the corner no longer feels flat. FP1 and FP2 are relatively calm aside from crashes involving Perez/Albon. Oscar Piastri tops FP2 ahead of Antonelli and Russell, with McLaren looking genuinely competitive on one-lap pace. Meanwhile Ferrari’s grip on softs worries the hosts, and Red Bull appears stuck in the midfield again, possibly due to aero confidence and even weight concerns. Reliability issues continue to loom.
With some alterations to energy deployment and changes at the front of the field, it's shaping up to be an interesting weekend at the Japanese Grand Prix...

Japanese Grand Prix
"Hello everybody and welcome back to the P1 Podcast with Matt and Tommy, Japanese Grand Prix Friday. Let's talk about it. We've got some news. We've got some things going on in the world of Formula One in the lead-up to this."
The Japanese Grand Prix is one of the big Formula 1 races. Teams use practice sessions to test how their cars feel and how fast they can go before the main events.
The Japanese Grand Prix is a Formula One race on Japan’s F1 calendar. In F1, “practice” and other sessions are used to evaluate car setup, tire behavior, and driver pace before qualifying and the race.
Formula One
"Let's talk about it. We've got some news. We've got some things going on in the world of Formula One in the lead-up to this. And also some things to discuss now that we've seen the cars around the legendary Suzuki Circuit."
Formula One is the highest level of race car competition. Teams constantly adjust their cars, and practice sessions help them figure out what works best.
Formula One (F1) is the top tier of open-wheel racing, where teams develop highly technical cars and compete on road-course circuits worldwide. “Practice” sessions are especially important because they help teams validate aerodynamic setup and tire strategy.
Suzuka
"So the first thing to talk about, because we mentioned didn't we previously coming into Suzuka that there might be some adjustments and changes to do with the battery? The wonderful thing we love to talk about."
Suzuka is the famous race track in Japan used for the Japanese Grand Prix. Because it has lots of fast and slow corners, how the car uses its energy matters a lot.
Suzuka is the Japanese circuit that hosts the Japanese Grand Prix. It’s known for a mix of high-speed sections and heavy braking/acceleration zones, which makes energy usage and battery deployment especially important.
energy recharge
"...made a small adjustment to the maximum energy recharge from nine megajoules to eight megajoules for qualifying. Essentially taking away a slight bit of the reliance of the battery..."
Energy recharge is about collecting and storing energy in the car. Then later the driver can use that stored energy to help the car go faster.
Energy recharge refers to how much electrical energy the car can recover and store under the FIA rules. It’s distinct from deployment: recharge is about storing energy, while deployment is about using it for acceleration and speed.
FIA
"But the FIA, you know, they've heard, they've listened to the F1 teams and perhaps the fans and made a small adjustment to the maximum energy recharge..."
The FIA is the organization that makes the rules for Formula One. In this case, they changed an energy rule that affects how the cars perform in qualifying.
The FIA (Fédération Internationale de l’Automobile) is the governing body that sets and enforces F1 technical and sporting regulations. Here, it’s directly adjusting hybrid energy rules to influence qualifying performance.
early in the season
"It's obviously this was one of the worst circuits for it. We're early in the season as well where they're still trying to work everything out."
Early in the season, teams are still figuring out the best setup and strategy. So performance can be a bit inconsistent while they learn what works.
Being early in the season means teams are still learning and optimizing around the current rules, upgrades, and track-specific setups. That often leads to less consistent performance as they refine energy-management strategies.
130R
"I mean, 130R is one of the best corners in Formula One, the whole calendar... And we're used to them flying through 130R, you know, flat out."
130R is a famous high-speed corner at Suzuka Circuit in Japan, known for being taken flat-out in ideal conditions. Because it’s so iconic, changes to how cars can attack it (or how much they must lift) strongly affect fan perception of the session quality.
chicane
"...you're just slowly, slowly, slowly losing speed into the chicane. And I know it's only practice..."
A chicane is a sequence of tight turns designed to slow cars down and create a technical driving section. In the context of 130R, losing speed into a chicane suggests drivers are struggling to maintain momentum after a high-speed entry.
onboard
"And I know it's only practice, but I saw an onboard with Max and that was about 50 kph he lost from essentially the top speed."
An onboard camera shows the driver’s perspective, often including speed, throttle/brake inputs, and steering behavior. Comparing onboard data across sessions helps explain why a corner looks slower—like lifting earlier or failing to maintain top speed.
downshifting
"It's a big shame, you know, downshifting, of course, as well, which is always lovely to hear."
Downshifting is changing to a lower gear to increase engine braking and provide the right torque for corner entry or acceleration. In F1, hearing/seeing downshifts is often associated with how drivers manage traction and braking stability into complex sections.
McLaren Honda
"It feels like a picture where they're kind of sat with a Honda engineer and they're kind of like, McLaren Honda days and how they need to be careful to not blow the relationship up..."
McLaren Honda was a famous F1 team pairing. The hosts are using that history as an example of how partnerships can either work out well or get strained if things don’t go right early.
“McLaren Honda” refers to the well-known F1 partnership between McLaren and Honda, especially during the turbo-hybrid era. The hosts use it as a comparison point for how engine/relationship dynamics can affect performance and long-term collaboration.
turn it around
"...they need to be careful to not blow the relationship up within the first two races because they can turn it around. We saw that what they did with Red Bull."
“Turn it around” in F1 usually means quickly improving results after a poor start through upgrades, better setup, and resolving technical issues. The hosts connect it to how quickly teams can recover once they identify what’s wrong.
one lap
"Because they look on par with Mercedes around one lap. They really do across FP1 and FP2."
“One lap” pace refers to short-run, single-lap performance—often measured during flying laps. The hosts say McLaren look on par with Mercedes around one lap, which suggests strong qualifying-like speed even if race consistency is still uncertain.
flying laps
"I will say that for Ferrari, they looked much better on the mediums when they were doing flying laps. But as soon as they put on the softs, they couldn't take that step..."
Flying laps are timed laps where the car is already at speed before the timing point, so the lap reflects peak performance rather than acceleration out of a slow corner. The hosts use flying laps to compare how teams perform on different tire compounds.
podium
"Depending on the steps they take between now and tomorrow to challenge not just for pole, but perhaps even beyond the podium and race wins."
The podium is the top three finish positions in a race (1st, 2nd, 3rd). The hosts use it as a benchmark for whether McLaren’s improvement could translate from practice pace into race results.
race wins
"Depending on the steps they take between now and tomorrow to challenge not just for pole, but perhaps even beyond the podium and race wins."
Race wins are the ultimate goal in F1 and depend on more than one-lap speed—strategy, tire management, and reliability all matter. The hosts frame McLaren’s Friday improvement as potentially enough to fight for wins, not just qualifying positions.
Red Bull
"I've good surprise Red Bull. They look shocking. We'll talk about them in a bit."
Red Bull is one of the big Formula 1 teams. If they look fast in practice, it usually means they have a good chance to be competitive later that weekend.
Red Bull is a top Formula 1 team and engine/operations partner that frequently competes for wins. In practice sessions, strong pace can signal whether they’re set up well for qualifying and race day.
torque
"...and a lot of torque already coming into this weekend..."
Torque is what helps the car accelerate. More torque usually means the car feels stronger when you put your foot down, especially out of corners.
Torque is the twisting force produced by the engine, which strongly affects acceleration. In F1 commentary, “a lot of torque” usually points to strong pull from low to mid engine speeds—useful for exits and for getting up to speed quickly.
Ferrari
"And the members are that Ferrari believe, obviously they're going to believe, and I firmly believe as well, that they are at least 2% behind the best engine."
Ferrari is a major F1 team. Here, they’re being judged on how close their car’s engine performance is to the fastest team.
Ferrari is one of F1’s top teams, and the speaker discusses its engine performance relative to the best. The segment frames Ferrari as potentially slipping to the third-fastest team if it can’t close the gap.
Mercedes
"...close that gap to which I think is astronomical for the Mercedes. And it's interesting."
Mercedes is another top F1 team. The speaker thinks Mercedes might not be showing its full speed, which could affect how close other teams can get.
Mercedes is discussed as having a large performance advantage, but the speaker suggests it may be holding back. The claim is that showing less performance could make it harder for rivals to catch up under the rules.
safety car restart
"On the safety car restart, they ended up, I think, clearing the entire field by about seven or eight seconds in a couple of laps, which if that is the case again..."
A safety car restart is when the race restarts after a slower period. The speaker claims that at one restart, Mercedes looked unusually fast compared to everyone else.
A safety car restart is when the race resumes after the safety car period, and cars accelerate back to racing pace. The speaker uses it as an example where Mercedes allegedly showed a big performance jump.
Nico Rosberg
"...because one race where Lewis Hamilton and Nico Rosberg got to race."
Nico Rosberg is another former Mercedes F1 driver. The speaker cites him to talk about a past Mercedes performance example.
Nico Rosberg is referenced alongside Hamilton as the other Mercedes driver in the example race. The speaker uses that historical reference to argue Mercedes’ performance management may be strategic.
Lewis Hamilton
"...because one race where Lewis Hamilton and Nico Rosberg got to race."
Lewis Hamilton is a famous F1 driver who raced for Mercedes. The speaker brings him up to describe a past race where Mercedes looked extremely dominant.
Lewis Hamilton is a multi-time world champion and a key Mercedes driver referenced as part of the example. The speaker uses his and Rosberg’s race to support the idea that Mercedes sometimes runs differently than it appears.
pole in Austria
"...Williams turned up the wick a little bit too much on their Mercedes engine and got pole in Austria. That's that same year, isn't it?"
“Pole” means you qualify first, so you start the race from the front. The speaker uses Austria as an example of how engine choices can lead to a big qualifying result.
“Pole” means qualifying first, giving the best starting position for the race. The speaker connects this to engine usage and performance testing, suggesting that pushing engine settings can swing results dramatically.
Williams
"And that's the same year where Williams turned up the wick a little bit too much on their Mercedes engine and got pole in Austria. That's that same year, isn't it?"
Williams is an F1 team. The speaker says Williams pushed their Mercedes-powered car harder than expected and it helped them get pole in Austria.
Williams is another F1 constructor referenced as having “turned up the wick” too much on a Mercedes engine in Austria. This implies engine mapping/usage choices can affect qualifying results and perceived competitiveness.
midfield
"Red Bull are a midfield. We've joked about this before. We've joked about, well, if Max was in Red Bull, there'd be a midfield car. Well, Max is in Red Bull and it is still a midfield car."
“Midfield” means the teams are in the middle of the pack—fast enough to race for points, but not usually fighting for the win.
“Midfield” in F1 means the group of teams that are not consistently fighting for the podium but are close enough to battle for points. The speaker uses it to frame Red Bull’s unexpected performance level in this session.
chassis
"And Red Bull, who I thought bringing upgrades to this weekend should be able to take a step forward because the idea and the understanding is that it's not the engine, it's the chassis."
“Chassis” is basically the car’s foundation and how everything is put together to handle. If the chassis isn’t working right, the car can feel unpredictable in turns.
In F1, “chassis” covers the car’s overall structure and setup—how it flexes, how suspension geometry works, and how the aero loads are managed. The speaker implies the chassis behavior is causing the lack of confidence and poor cornering.
understeering
"That's the problem with the car is that the drivers don't have any confidence. I think Max even said in practice today that he's understeering so much he's just going to box, not even going for another flying lap."
Understeering means the car doesn’t want to turn as much as you ask. The front tires don’t grip enough, so the car pushes wide in the corner.
Understeering is when a car turns less than the driver expects, causing it to push toward the outside of the corner. In F1 terms, it often points to an aero balance or setup issue (like front-end grip or overall aerodynamic load).
aero
"So the car is fundamentally wrong from an aero side of things, but seemingly good from an engine side, which is the opposite for a lot of other teams."
“Aero” is how the car’s shape and wings push it down onto the track. If the aero isn’t right, the car can feel wrong in corners even if the engine is fine.
“Aero” is short for aerodynamics—how wings, floors, and body shaping create downforce and balance. In F1, aero problems can make the car feel unstable or slow in specific corners, even if the engine is strong.
we're way off the pace
"...they struggled so much in the corners in China. They're obviously absolutely woeful and they're way off the pace seemingly here again."
“Off the pace” means the car isn’t as fast as the leading cars. It can be a sign that something about the setup or car performance isn’t working.
“Off the pace” means the car is slower than the competitive front-running group by a noticeable margin. In F1 practice, this often points to fundamental performance issues—either aero efficiency, balance, or power delivery.
20 kilos heavier
"They're all very similar. And then the Red Bull was, I think, like 20, 20 kilos heavier than everything else, which 20 kilos heavier when you're trying to go around the S's at Suzuka is going to, you know, feel a lot."
20 kg is a lot of extra weight for an F1 car. More weight makes it harder to change direction quickly, which matters on twisty sections like Suzuka’s S-curves.
A 20 kg weight difference is large in F1 and can meaningfully affect cornering performance, tire wear, and acceleration out of slow turns. The speaker ties it to Suzuka’s “S’s,” where frequent direction changes punish extra mass.
reliability still seeming to be quite an issue
"And yeah, reliability still seeming to be quite an issue for a lot of drivers."
They’re saying cars are still breaking down too often. If that keeps happening, it can ruin race results and the championship picture.
The speaker is emphasizing a recurring reliability problem across multiple drivers/teams. In F1, reliability issues can erase practice progress and lead to DNFs, which dramatically affects championship outcomes.
