Is the F1 Honda PU Okay? Decoding Aston Martin's Current Position from the 2026 Season Opener Telemetry
Delayed testing and PU troubles. Uncovering the mystery of the 'halved' motor output compared to the benchmark and diving into the current state of under-optimization.

Is the F1 Honda PU Okay? Decoding Aston Martin's Current Position from the 2026 Season Opener Telemetry

The Cruel Reality Revealed by Telemetry: A 20 km/h Deficit in Top Speed

Just like running a benchmark on a gadget, the true potential of an F1 car becomes glaringly obvious through telemetry—the 'data that doesn't lie.' Graph 1 shows the speed and throttle opening for each driver, confronting us with the cruel reality that the top speed of the Aston Martin Honda (Alonso's car) is overwhelmingly lagging behind other manufacturers.

At the top speed point, it is not only about 20 km/h slower than the high-end benchmark Mercedes PU, but it also consistently remains at lower speeds throughout other full-throttle sections. On the other hand, Audi (Bortoleto), a completely new entrant from 2026, clocked numbers almost identical to Mercedes in top speed. This is proof that the peak output of the Audi PU has already reached the top tier.

This fatal lack of speed in the Honda PU goes far beyond what can be excused by superficial setup differences like aerodynamic efficiency or wing settings. It is clear that a combination of delayed testing and PU-related troubles is preventing the car from demonstrating its true performance, demanding urgent root cause analysis and 'debugging.'

2026 Spec F1 PU Performance Comparison Table (Telemetry Estimates)

First, let's summarize the current performance of each PU. The table below provides a comprehensive evaluation that includes not just mere peak output (catalog specs), but also the 'practical usability' of energy management.

Comparison TargetDriverTop Speed EvaluationTime Loss (vs. Mercedes)Current Overall Evaluation
Mercedes PURussell (RUS)Top Level (Benchmark)Baseline (0.00s)High-end with no blind spots in output and regeneration
Audi PUBortoleto (BOR)Equivalent to Mercedes+0.80s (Straight average only)Excellent peak output, but issues in management
Honda PUAlonso (ALO)Severe delay of -20 km/h+2.44s (Straight only)Significant lack of output. Urgent bug fixes required


Laying it out like this highlights the 'under-optimization' of the Honda PU. From the next section, we will dive deep into the three PUs listed in the table individually, thoroughly reviewing their pros and cons without any bias.

[In-Depth Analysis] The Overwhelming Benchmark: 'Mercedes PU'

In current F1, the Mercedes PU reigns supreme as the pinnacle of PU performance and energy management—the absolute benchmark. To put it in perspective, it boasts a level of perfection akin to the latest high-end smartphone where the OS and hardware are flawlessly integrated.

Its greatest advantage lies in its overwhelming 'refinement.' George Russell's telemetry reveals exceptionally brilliant energy management, with motor deployment continuing uninterrupted right to the end of the straights. The balance between battery consumption and regeneration is exquisitely controlled, making its ability to consistently deliver high performance on any circuit (use case) its greatest strength.

It is finished to such a degree that finding a drawback is difficult, but if one were to nitpick, it would be that the controls required to maintain this perfect system have become incredibly complex. While there is a risk that this delicate balance could be disrupted during future updates or regulation changes, it is undoubtedly the most reliable and powerful power unit on the grid right now.

[In-Depth Analysis] The Astonishing Newcomer: 'Audi PU'

The Audi PU is drawing attention as a completely new entrant manufacturer from 2026, and Gabriel Bortoleto's data reveals a peaky charm, much like an 'emerging manufacturer's gaming smartphone boasting astonishing specs.'

The advantages are clear. The foundational design of the internal combustion engine (ICE) and the motor is excellent, and in terms of peak output, it is already closing in on the champion, Mercedes. The hardware potential to extract this top speed right out of the gate as a new entrant is genuinely commendable.

However, significant challenges remain in practical usability (drivability). Analyzing the speed transitions sector by sector reveals areas where the speed drops off, as if the car is gasping for breath in specific sections. This is evidence that the software-side energy management is immature, failing to optimally distribute power throughout a single lap. While the peak power is tremendous, the high difficulty of setup makes it an untamed beast that chooses its driver, which is its current drawback.

[In-Depth Analysis] Suffering a Severe Slump: 'Honda PU'

And now to the main subject: the Honda PU mounted on the Aston Martin, which undeniably suffers from the most severe bugs at present. Even with a rare top driver like Fernando Alonso desperately at the wheel, the data presents a cold, hard reality.

The fatal drawback is an absolute lack of output and sluggish top speed growth. Watching it get left behind by other cars one after another on the straights is like watching a processor suffering from severe thermal throttling. With a massive gap in qualifying best times—3.45 seconds behind Russell and 1.74 seconds behind Bortoleto—the packaging with the chassis and the integration of the setup have completely collapsed.

If there is a single advantage or saving grace, it would be the massive room for improvement, as 'it can't get any worse than this.' Considering Honda's foundational technological prowess, the hardware itself shouldn't be junk. If they can squash troubles like vibration issues and the team and manufacturer rush to optimize system integration, it holds more than enough potential to return to the midfield group.

Fatal Time Loss Occurring Just on the Straights

Graph 2 visualizes Alonso's time loss in the full-throttle sections. We have already pointed out the lack of speed, but watching it accumulate as a 'time gap' sends shivers down the spine at the severity of the situation.

Looking at the specific numbers, he faces a disadvantage of 2.44 seconds against Russell and 1.64 seconds against Bortoleto just in the straight sections alone. This is not on a level that can be overturned by superficial setups like cornering techniques or minor aero adjustments. The battle is lost before even reaching the end of the straight, leaving the car in a 'paperweight state' where defending, let alone overtaking, is impossible.

This overwhelming delay strongly suggests that it is not merely due to air resistance, but that the deployment (release of electrical energy) from the PU is extremely short or intentionally restricted. Readers interested in more detailed data analysis or the latest F1 telemetry tools should definitely check out the details from the links below.

Cumulative Time Loss Trend in Full-Throttle Sections

Motor Output Halved? Decoding the Power Gap from Acceleration Data

Finally, let's calculate the specific power gap from the acceleration data in Graph 3. Assuming that the basic performance of the ICE is frozen and all companies are on equal footing, this difference in acceleration can be directly interpreted as the difference in motor (MGU-K) output.

As a result of the calculation, a shocking fact was revealed: the Honda PU's output is approximately 146 kW lower compared to the Mercedes PU. This calculates to them only being able to use 'about half' of the motor output they should originally be demonstrating. Whether a fail-safe has been triggered due to severe vibrations or they are dealing with serious hardware troubles is uncertain, but there is no doubt that it is far from a normal operating environment.

There is no room for Aston Martin and Honda to be shifting the blame onto each other. Considering the lack of test running, there is a mountain of room for improvement on both the software and hardware sides, such as optimizing mapping and refining the chassis setup. We hope they fix these bugs as soon as possible and bring out the true specs. If you are curious about the latest F1 trends or related gadgets, be sure to check the details from the links below.

Mountains of Challenges, but Plenty of Potential for a Comeback

The current state of Aston Martin Honda, exposed by the 'benchmark that doesn't lie' known as telemetry, was a severe error state equivalent to the motor output being halved. The gap with the absolute champion Mercedes and the emerging Audi boasting astonishing specs is cruelly wide. However, the hardware's potential is not completely dead. If thorough debugging and setup maturation progress, there is ample possibility of achieving a dramatic performance boost. We will continue our verification, looking forward to a counterattacking update.
