How to use the F1 Top Speed Comparison

The F1 Top Speed Comparison allows you to compare recorded Formula 1 speeds between drivers across practice, qualifying, Sprint and Grand Prix sessions.

Select a Grand Prix, choose an available session and then select any two drivers. You can compare their maximum recorded speeds at several timing references around the circuit, examine repeated high-speed readings, follow speed values lap by lap and see how both drivers rank against the full field.

Charles Leclerc and Lewis Hamilton are selected by default where both have available data, making the comparison particularly useful for Ferrari fans. However, any two drivers with usable timing data in the selected session can be compared.

The analysis is designed to answer questions such as:

which driver recorded the highest speed in a session
how Charles Leclerc and Lewis Hamilton compared at different speed references
whether a driver’s highest speed was repeatedly approached or appeared as an isolated peak
how every driver ranked at the selected speed reference
which constructor recorded the highest speed
how top-speed readings changed between laps and sessions

Which Formula 1 sessions can be compared?

The comparison supports locally available Formula 1 sessions including:

Practice 1
Practice 2
Practice 3
Qualifying
Sprint Qualifying
Sprint
Grand Prix

Only sessions that actually took place during the selected race weekend and have usable imported timing information are displayed.

This means traditional Grand Prix weekends and Sprint weekends can naturally provide different combinations of sessions.

What does top speed mean in this comparison?

Top speed represents the highest plausible recorded value available at the selected timing-based speed reference during the chosen session.

It should not automatically be interpreted as the absolute physical maximum speed reached by the car anywhere on the circuit.

The available timing data provides several distinct speed references located at different points around the lap. The comparison therefore allows you to examine those references individually rather than combining them into one artificial number.

Longest-straight speed

The Longest-straight speed reference represents the recorded speed value associated with the circuit’s longest-straight timing reference in the available session timing data.

It is generally one of the most useful options when comparing high-speed performance because it provides a consistent reference across drivers within the same session.

However, a higher longest-straight speed does not automatically prove that one car has a more powerful engine or lower aerodynamic drag.

The reading can also be influenced by slipstream, active-aerodynamic configuration, battery deployment, wind, traffic and how well the driver exited the preceding corner.

Intermediate 1 and Intermediate 2 speed

The Intermediate 1 and Intermediate 2 speed values are separate timing-based speed references located at different points around the circuit.

Because circuit layouts vary significantly, the characteristics of these locations can also differ. One may sit near the end of a substantial straight while another can be influenced more heavily by the preceding corner or acceleration zone.

Comparing both intermediate references can therefore reveal that two cars do not necessarily have the same relative speed advantage everywhere around the circuit.

Finish-line speed

The finish-line speed represents the recorded speed at the start/finish timing reference.

This measurement can provide useful additional context but should not automatically be treated as the circuit’s primary top-speed figure.

On some tracks, the finish line is positioned well before the end of the main straight. At others, the configuration of the final corner can have a substantial influence on the recorded speed.

Why the different speed references matter

Intermediate 1, Intermediate 2, finish line and longest straight are separate timing-based speed references located at different points around the circuit.

A driver who is fastest at one reference may not necessarily be fastest at another.

This can happen because straight length, preceding-corner speed, acceleration, aerodynamic configuration, energy deployment and traffic can influence each reference differently.

Looking at several speed points therefore provides more context than relying on a single top-speed number.

Maximum speed

The selected-driver overview shows the highest plausible recorded speed for each driver at the chosen reference.

The value is calculated from the locally processed session data after generated and explicitly inaccurate timing rows have been removed.

The maximum provides a useful indication of peak recorded speed, but one isolated reading should not always be treated as representative of a driver’s normal session performance.

What is the top-three median?

The top-three median provides additional context for the maximum-speed figure.

It is calculated from the median of the driver’s three highest recorded values at the selected speed reference. If fewer than three usable readings exist, all available values are used.

For example, a driver may record a maximum of 336 km/h but have a top-three median of 330 km/h. That can indicate that the peak value was considerably higher than the driver’s other best readings.

Another driver might record a maximum of 334 km/h with a top-three median of 333 km/h, showing that the highest speed was repeatedly approached.

This does not automatically determine which performance was more impressive, but it gives readers useful context that a single maximum cannot provide.

Recorded speed samples

The overview also shows the number of usable speed readings available for each selected driver at the chosen reference.

Sample count is important because drivers do not necessarily complete the same number of laps in every session.

A driver with only two usable readings has a much smaller sample than a driver with eight or ten.

The sample count should therefore be considered alongside both the maximum and top-three median.

Field rank and tied speeds

The field-rank metric shows where each selected driver ranks according to their session maximum at the chosen speed reference.

Drivers with the same recorded maximum speed share the same tied rank. A tied position is displayed using the letter T.

For example:

T14 means the driver shares 14th place with at least one other driver.

The top-three median can be used to order tied rows visually in the full-field table, but it does not break the official displayed tie.

This ensures that drivers with identical recorded maximum speeds are not given artificially different rankings.

Gap to the session fastest

The gap metric shows the difference between a selected driver’s maximum speed and the highest recorded maximum at the same reference in the session.

For example:

6.0 km/h slower

means that the driver’s highest recorded speed was six kilometres per hour below the session-leading value.

The gap is descriptive only and should not be interpreted as a direct engine-performance deficit.

Maximum-speed lap

The comparison identifies the lap on which each selected driver’s highest recorded speed occurred.

This is useful because it allows the maximum to be placed into the context of the driver’s session programme.

A peak speed may have occurred during an early qualifying attempt, a later lap with a slipstream or a race lap in traffic.

Knowing the lap number can help readers investigate that context rather than treating the maximum as an isolated statistic.

Lap time on the maximum-speed lap

The lap time associated with the maximum-speed reading is displayed where available.

This value is provided for context only.

The lap carrying the highest straight-line speed does not necessarily need to be the driver’s fastest lap of the session.

A driver can record an exceptional speed through a timing reference while losing time elsewhere around the circuit.

Tyre context

Where available, the comparison displays the recorded tyre compound and tyre-age information associated with the maximum-speed lap.

This can help place two maximum-speed readings into better context, particularly when one driver was using a fresh set while another was running on an older tyre.

Tyre information should not be treated as a complete explanation of a speed difference. Grip, tyre preparation, pressure, temperature and the preceding corner can all influence the speed carried onto a straight.

Lap-by-lap speed comparison

The lap-by-lap chart shows representative recorded speeds for the two selected drivers at the chosen timing reference throughout the session.

This makes it possible to see whether a driver’s high-speed performance remained relatively consistent or changed significantly between laps.

The chart focuses on readings at least 90% of each selected driver’s session maximum at the chosen reference.

Lower readings are omitted from the chart only so that obvious low-speed laps do not distort the vertical scale and make representative high-speed attempts difficult to compare.

This visual filter does not change:

the stored session data
the driver’s maximum speed
the top-three median
the recorded sample count
the field ranking

Breaks in the chart indicate laps without a displayed reading.

Why low-speed laps can appear in session data

Not every lap completed during a Formula 1 session is a representative high-speed attempt.

Drivers may be:

preparing tyres
cooling the car
managing traffic
entering or leaving the pits
running slowly between qualifying attempts
following a different practice programme

For this reason, the public chart focuses visually on the driver’s higher-speed readings while leaving the underlying session statistics unchanged.

Full-field top-speed ranking

The full-field ranking compares every driver with usable timing data at the selected speed reference.

The table includes:

maximum-speed rank
driver
constructor
session maximum
gap to the fastest recorded speed
top-three median
number of usable samples
maximum-speed lap
tyre context where available

Drivers are ranked according to their highest recorded value in the selected session.

Equal maximum speeds share the same tied rank.

The top-three median provides additional context and can order equal-speed rows for readability without changing their displayed rank.

Constructor top-speed ranking

The constructor ranking provides a team-level view of the selected session.

Each constructor is represented by the highest recorded speed achieved by either of its drivers at the selected reference.

This approach avoids averaging together two cars that may have completed very different programmes or encountered different traffic.

Constructors with identical maximum speeds share the same tied rank.

The ranking is descriptive session data and should not be interpreted as a definitive power-unit or aerodynamic-efficiency ranking.

Why top speed does not equal engine power

One of the most important limitations of Formula 1 speed data is that maximum speed is influenced by much more than engine output.

A recorded speed can be affected by:

aerodynamic configuration
active-aerodynamic state
energy deployment
slipstream
wind direction and strength
traffic
tyre condition
corner-exit speed
driver technique
car balance
session programme

A car can therefore record a lower straight-line speed while still producing a faster lap overall.

Likewise, a car with the highest speed reading cannot automatically be described as having the most powerful engine.

Slipstream and tow effects

A slipstream can significantly affect straight-line speed when one car follows another closely enough to benefit from reduced aerodynamic resistance.

This is particularly relevant in qualifying sessions and on circuits with long straights.

An isolated maximum that is noticeably higher than a driver’s other readings may therefore have been influenced by a tow.

The top-three median can help provide context by showing whether the maximum was repeatedly approached, but the available aggregate timing data does not independently prove whether a particular reading was tow-assisted.

2026 active aerodynamics and top speed

The 2026 Formula 1 regulations introduce active aerodynamic behaviour that can influence straight-line performance.

The aggregate session timing available to this comparison does not provide a complete, reliable active-aerodynamic state for every speed reading.

For that reason, the tool does not attempt to classify each maximum according to a specific active-aero configuration.

Active-aerodynamic behaviour should instead be considered one of several possible influences when interpreting speed differences.

Energy deployment and straight-line speed

Hybrid energy deployment can have a substantial impact on recorded straight-line speed.

Drivers and teams may not use identical deployment strategies on every lap, especially during practice sessions or different qualifying phases.

The available aggregate timing data does not expose enough information to equalise every speed reading according to energy deployment.

A difference in maximum speed should therefore not automatically be described as a difference in combustion-engine performance.

Corner exit and top speed

The speed at the beginning of a straight can influence the speed reached later along that straight.

A driver who exits the preceding corner more quickly may carry that advantage through much of the acceleration zone.

Conversely, a driver can have strong straight-line characteristics but reach a timing reference at a lower speed after a compromised corner exit.

This is one reason why top-speed figures should be analysed alongside lap-time and telemetry information rather than independently.

Deleted laps and speed readings

A lap deleted for track limits is not automatically removed from the speed comparison solely because the completed lap time was invalidated.

The reason is that the speed recorded at a timing reference can still represent a meaningful physical measurement even if the driver’s lap was subsequently deleted for exceeding track limits elsewhere around the circuit.

Generated and explicitly inaccurate timing rows are excluded.

The methodology therefore distinguishes between the validity of a completed lap time and the usability of a recorded speed reference.

Top speed compared with qualifying pace

Top speed is only one component of qualifying performance.

A driver can be slower on the straights but gain enough time under braking, through corners or during acceleration to complete the faster lap.

For a broader qualifying comparison, use the F1 Qualifying Pace & Sector Comparison.

That analysis provides qualifying lap times, sector performance, theoretical best laps, progression through Q1, Q2 and Q3 and additional speed context.

Top speed compared with qualifying telemetry

For a more detailed examination of how two drivers generated their qualifying performance, use the F1 Qualifying Telemetry & Corner Comparison.

The telemetry comparison examines speed throughout the entire lap together with throttle, braking, gear, RPM and elapsed-time delta.

The top-speed comparison serves a different purpose: it allows speed references to be compared across a much wider range of Formula 1 sessions without requiring full car telemetry for every lap.

Top speed during practice sessions

Practice-session speed figures require particular care because teams may be running very different programmes.

Fuel load, setup work, energy deployment, tyre condition and run objectives can all differ between cars.

For a more complete examination of practice performance, use the F1 Practice & Long-Run Analysis.

That tool combines fastest valid laps, best-three pace, long-run candidates, consistency, observed stint trends, sectors and session conditions.

Top speed during a Grand Prix

Race-session top speed can be strongly influenced by competitive circumstances.

A driver following another car may benefit from a slipstream, while traffic, tyre condition, energy management and strategic objectives can all affect the recorded value.

For sustained race-performance analysis, use the F1 Race Pace & Lap Time Comparison.

You can also use the F1 Race Position & Progression Tracker to examine how traffic and running position developed during the Grand Prix.

Ferrari top-speed comparisons

Charles Leclerc and Lewis Hamilton are selected by default where both have usable session data, allowing Ferrari fans to quickly compare the team’s two drivers.

The comparison can show whether one Ferrari recorded a higher maximum, whether the difference appeared at all speed references, how repeatable their strongest readings were and where each driver ranked against the field.

The comparison is not limited to Ferrari. Any two drivers with suitable session data can be selected.

For a broader season-long Ferrari teammate comparison, visit the Charles Leclerc vs Lewis Hamilton F1 Head-to-Head Statistics page.

You can also compare Ferrari’s wider performance against other constructors using Ferrari vs F1 Rivals.

Does the top-speed comparison use full car telemetry?

No.

The comparison uses aggregate session lap timing and the speed references included in that dataset.

It does not download full speed, throttle, brake, gear or RPM telemetry for every lap.

This allows a much larger range of sessions to be processed efficiently while keeping the public comparison lightweight.

Detailed qualifying telemetry remains available separately through the F1 Qualifying Telemetry & Corner Comparison.

How the F1 Top Speed Comparison is optimised for page performance

Session timing data is downloaded and processed separately through the website administration area.

Visitors do not trigger external Formula 1 timing requests when they open the page or change a driver, session or speed reference.

The public comparison reads compact locally stored JSON data containing the information required for the selected session.

This architecture helps keep the page responsive while avoiding repeated downloads of the original external dataset for every visitor.

Methodology and limitations

The F1 Top Speed Comparison uses aggregate session lap timing rather than full car telemetry.

Generated and explicitly inaccurate timing rows are removed before the public comparison is created.

The session maximum is the highest plausible recorded value for a driver at the selected speed reference.

The top-three median is the median of the driver’s three highest available readings, or all readings when fewer than three values exist.

Equal maximum speeds share the same tied rank. Top-three median can be used to order tied rows visually but does not break the displayed tie.

The public lap-by-lap chart omits readings below 90% of each selected driver’s session maximum at the chosen reference so that obvious low-speed laps do not dominate the chart scale. This chart-only filter does not change the underlying maximum, median, sample count or ranking.

A speed reading can remain usable even when its lap was deleted for track limits because the recorded speed itself can still be meaningful. Generated and explicitly inaccurate rows are excluded.

Top speed depends on more than engine output. Aerodynamic configuration, active-aero behaviour, slipstream, energy deployment, tyre condition, wind, traffic and preceding-corner exit can all influence the recorded value.

The statistics should therefore be interpreted as observed session speed data rather than as a direct measurement of engine power, aerodynamic efficiency or overall car performance.

Frequently asked questions

What is the F1 Top Speed Comparison?

It compares recorded Formula 1 speed references between drivers across available practice, qualifying, Sprint and Grand Prix sessions.

Which drivers can I compare?

You can compare any two drivers with usable timing data in the selected session. Charles Leclerc and Lewis Hamilton are selected by default where both are available.

Which sessions are supported?

The comparison can support Practice 1, Practice 2, Practice 3, Qualifying, Sprint Qualifying, Sprint and Grand Prix sessions where the relevant race weekend contains that session and usable data is available.

What is the session maximum?

It is the highest plausible recorded speed for the driver at the selected timing reference after generated and explicitly inaccurate rows have been removed.

What is the top-three median?

It is the median of a driver’s three highest recorded values at the selected speed reference. It helps show whether the maximum was repeatedly approached or was more isolated.

What does T14 mean?

T14 means that the driver is tied for 14th place according to session maximum speed. All drivers with the same maximum share the same tied rank.

Why can drivers with the same maximum appear in a different order?

The top-three median can be used to order tied rows for readability, but every driver with the same maximum retains the same displayed tied rank.

Why are some laps missing from the lap-by-lap chart?

The chart omits readings below 90% of each selected driver’s session maximum so that obvious low-speed laps do not distort the high-speed comparison. The readings remain part of the locally stored session data.

Does the fastest car have the most powerful engine?

Not necessarily. Top speed can be influenced by aerodynamics, slipstream, active-aero behaviour, energy deployment, tyres, wind, traffic and corner exit as well as power-unit performance.

Does a higher top speed mean a faster lap?

No. A car can gain straight-line speed while losing more time through corners, braking zones or acceleration phases.

Is the longest-straight value the official maximum speed reached anywhere on the lap?

Not necessarily. It is a timing-based speed reference associated with the longest-straight measurement available in the session data.

Why is finish-line speed different from longest-straight speed?

They are recorded at different physical points around the circuit. The finish line is not necessarily located at the point where cars reach their maximum straight-line speed.
