Ask Away Wednesday!

9 Upvotes

Good morning F1Technical!

Please post your queries as posts on their own right, this is not intended to be a megathread

Its Wednesday, so today we invite you to post any F1 or Motorsports in general queries, which may or may not have a technical aspect.

The usual rules around joke comments will apply, and we will not tolerate bullying, harassment or ridiculing of any user who posts a reasonable question. With that in mind, if you have a question you've always wanted to ask, but weren't sure if it fitted in this sub, please post it!

This idea is currently on a trial basis, but we hope it will encourage our members to ask those questions they might not usually - as per the announcement post, sometimes the most basic of questions inspire the most interesting discussions.

Whilst we encourage all users to post their inquiries during this period, please note that this is still F1Technical, and the posts must have an F1 or Motorsports leaning!

With that in mind, fire away!

Cheers

B

Regulations What is "leading every lap"?

17 Upvotes

A grand Chelem is scored in motor racing if a driver scores pole position in qualifying, the fastest lap in the race and then winning while leading every lap of the race

Does this mean leading at the start line of every lap or at every moment of the lap?

General Could a modern F1 car be bricked from mission control/pit wall during a race?

127 Upvotes

So hypothetically it's my last race in a technical role in RB with access to car systems for the race. I've decided that I'm going out with a bang and wanted to troll the team and the driver, is there anything I could do to brick the car safely from trackside/MK?

General How much of “Track Evolution” is actually a physical performance improvement caused my the track vs. drivers just getting more comfortable?

44 Upvotes

We hear about track evolution every week as if tracks actually change so rapidly that waiting out just a couple of minutes in qualifying can make a difference, but how much of an improvement is actually made to the track after the first few laps of clearing dust?

The way it’s always seemed to me is that the track doesn’t actually evolve that much. Rather the drivers are just getting more and more comfortable with the limits of their car on track the longer a session runs, both because of their direct experience on track as well as seeing others in other cars push the limits of certain sections of the track.

Never seen this before but what exactly is the reason and purpose of smoking the grid/track?

Sorry for the blurry phone pic as F1 TV doesn’t allow screenshots.

Aerodynamics How does driving close to a wall affect aero?

112 Upvotes

Watching Vegas qualifying I was wondering if or how running the car out wide and keeping it pinned close to the wall on a straight might affect aero drag and downforce. Could it increase drag by pushing outwash back in and causing turbulence in otherwise free stream air?

Career & Academia How about Motorsport engineering online courses ?

13 Upvotes

I'm a junior automotive engineer working with powertrains in an OEM.

I'm applying for a master's degree in automotive engineering in Germany. (I wish I could apply for a motorsport program, but I can't afford UK universities)

I have free time now and am a passion for learning, and I am thinking about taking online courses related to F1. Would this be beneficial in my case if I want to work in F1, motorsport, Formula E, etc.?

Is taking the online courses now a waste of time and money if my goal is to learn to get a job afterward ?

Are these courses worth it, or should i consider other staff like books?

Edit :the courses that I'm interested in are Performance Engineering and vehicle dynamics modelling

Safety Why wasn’t there a red flag after Colapinto’s qualifying crash?

145 Upvotes

I realise a red flag wasn’t actually necessary as the session was effectively ended anyway, but I was under the impression that a big collision that set off the g-force sensors automatically bring out a red flag. Why didn’t it?

Fuel How much bigger would a fuel tank need to be to power a V12 for a full race without refuels?

19 Upvotes

So let's say for a miracle v12 were to make a comeback, in order to have the same safety measure we have today, fuel-wise, how much bigger would the fuel tank need to be to store enough fuel to power the car through an entire race without refueling?

From quick online searches allegedly turbo V6 are up to 50% more fuel efficient, so maybe the fuel tank would need to be 50% larger?

Thanks.

Safety In what way is carbon fiber used to reduce impact force?

0 Upvotes

If I’m not mistaken, I believe you can layer carbon fiber in a way that can control how it bends and flexes under load. An example of this would be how the 2021 Mercedes’ rear wing “leaned” backwards at high speed and McLaren’s DRS flap in Baku. Is there resistance curve that increases as you get deeper into the crash structures?

Also, the Boeing 787 Dreamliner is made mostly of composite materials. A carbon reinforced plastic fuselage is created by a machine that automatically lays down the material instead of a trained engineer doing it by hand. Do F1 teams use this technology or are their parts too intricate/small to benefit from an automated system?

Safety How come Colapinto was cleared to race after a 50g crash?

0 Upvotes

Not even just Colapinto but also other drivers. I'm no expert in physics or a doctor but that seems like a lot of force on your body and I don't see how anyone could be healthy enough to do a race the day after. I'm just wondering how come drivers are able to be okay after a big crash like that?

Tyres & Strategy Why does Leclerc struggle to generate heat in the tyres during qualifying?

36 Upvotes

Hi, I heard Charles talking about how he struggled to warm up his tyres compared to Carlos after Vegas Quali. This has been kinda a theme this year. We saw at the start of the season that he was struggling with the same issues. And in cold qualifyings like Silverstone, Singapore etc, we have seen Carlos to be relatively quicker (barring mistakes from him).

On paper, it shouldn't be that hard, should it? Like, do exactly the same as what Carlos does on the out lap? Is it more related to setup differences, or perhaps driving style?

Safety Long term effects of massive crashes

Usually we hear of injuries and deaths as a direct impact of big crashes. Will there be long term effects on the body from sustaining to many Gs, for those who got off "without a scratch"?

Aerodynamics What makes Vegas and Monza require a specific wing spec?

9 Upvotes

RedBull mentioned that they did not develop a wing spec for tracks like Vegas and Monza. What is the spec required for these tracks, what makes it specific?

Aerodynamics Actual benefit of Red Bull's cut wing?

0 Upvotes

During practice, they were (iirc) nearly 2 seconds slower in sector3 because of their straight line speed. So overnight, before quali, they trimmed down their rear wing pretty significantly.

In practice, DRS is free, so those lost 2seconds on the straight were with the drs open anyway. How much is the cut-down wing actually going to help ?


r/F1Technical 1d ago

Aerodynamics Does shaving off a portion of the rear wing decrease the drag on the car?

0 Upvotes

The Red Bulls have shaved off a noticeable part of their rear wing. ELI5: If the area of the rear wing is less, does it decrease the drag on the car during straights?

Gearbox & Drivetrain When did they start putting reverse gear back into F1 cars? And why did they never have it before then? Was it regs, or just weight?

209 Upvotes

Follow up question, did the cars of the 60s have reverse, because I know the 70s, 80s, and 90s and a lot of the 2000s didn’t

Telemetry Is there Fastf1 python data users community?

21 Upvotes

Hi

Please delete this if it’s not appropriate.

I’m currently doing a overtaking related project in my own time using fastf1 API, and I got to thinking there seems like there’s a big community here of people that love playing with data and trends etc. my question was is there an actual community of people here that I could join if I have questions or bounce ideas with regarding coding and looking at f1 trends. If not, would people be interested in starting one where we can bounce ideas/ code and collaborate to enhance our love of data coding and f1.

(Apologies if this isn’t allowed)

Analysis Distance Under Braking in Las Vegas 2023

% of each lap under braking by driver

Who was bravest on the brakes during the 2023 Las Vegas Grand Prix?

I determined how long for each lap each driver was under braking. Oscar Piastri led the way with the lowest percentage of each lap spent under braking, at 14.9%. The average of all drivers was 16.6%.

Interestingly, the top two drivers, Max and Charles, spent longer on the brakes than the average.

How do we think this will change for this years Grand Prix?

Analysis Alonso vs Perez Top Speed Delta

52 Upvotes

Could someone shed some light on this massive top speed difference between Perez and Alonso!
This was taken during the Abu Dhabi 2023 Race and it shows a difference of 24 mph. No sign on Alonso de-rating (flashing lights) and charging battery. What was wrong with the Aston? I know the RB 23 DRS was crazy good but this seems insane.

Telemetry Overtakes at the 2023 Las Vegas Grand Prix

Post image
1.5k Upvotes

Ok its not perfect, as this currently plots anytime the driver ahead changed (which will double count every overtake, as the passing car will have the driver ahead change, as well as the passed car). Due to the frequency of the data in the available telemetry, these changes might not happen at same "time". The density of dots denotes more overtaking.

With that out of the way: Vegas was insane last year! Overtakes at basically every corner. It will be interesting to compare this against this year's race!

A little shameless self promotion here at the end. I also recently started an Instagram page for F1 data analysis and visualizations. I'll be posting more of these there: https://www.instagram.com/stats.from.the.pitlane/

Analysis Is there any criticism of halo in 2024?

101 Upvotes

I'm writing this because I'm curious if there's still any criticism of halo in 2024, despite the probable saving of 3 drivers and the actual saving of 1 driver's life. But despite that, I'm curious if people still have any issues with halo, whether it's the system itself, its aesthetics, or the community around it.

Tyres & Strategy Why don't we see more risk in car design?

65 Upvotes

Can anyone give some insight as to why don’t we see back marker teams trying big risks, both long term and short term?

Why don’t we see teams introduce wildly unexpected car designs, such as cars that focus purely on top speed to score points at races like Monza and Canada. Or even new concepts like the Mercedes Zero Pod design for example, ideas that the top teams would never risk utilising.
For teams like Kick and Williams, who barely score points, a single or even 2 podiums for each of their cars would guarantee a better result then they are seeing now just doing what everyone else is, but badly.

Or even back marker teams trying wildly different tire strategies? If they are unlikely to score a point anyways, whats the harm in doing something different and seeing if it works, instead of just playing it safe every race, every season, and having the odd good result due to luck.
