From Scratch to Track: How to design an F1 car | #drivedigitalsuccess #8

00:00:00: Welcome to drive digital 6s.

00:00:08: You're behind the scenes podcast about Formula 1 and the technology driving is presented by Chris medland and Mandy Carter Howard bionis.

00:00:18: First class cloud.

00:00:19: Music.

00:00:26: Hello and welcome to what is the final episode of our first series of the driver's digital success podcast brought to you by Argos I'm Chris medland.

00:00:34: And stable going to be getting technical with heart head of Engineering operations Ben agathangelou to talk about just how you go about designing a Formula 1 car.

00:00:43: Logan and thank you very much for taking the time to join us on the Isle of podcast you're the head of Engineering operations here at us but can explain to our listeners what exactly that means

00:00:53: what does that mean I suppose I spent the Year trying to define it properly is dinner and evolution for me in the last

00:00:59: having come from effectively getting up and running the Aero department.

00:01:04: A lot of backfill with good staff and the group in that regard runs itself very well what I

00:01:11: evolved into doing is effectively running anything that's associated with engineering

00:01:17: operations which basically means Business Systems organisational planning and

00:01:22: also because of my background in hero I've maintained if you like a function of the concept and application for the car

00:01:29: particularly notable this year because the regulations have been so different and so new that we had to draw as much experience as we speak and understand what it is that was needed for this regulation is another part of my function this year has been

00:01:43: infected to deal with the FIA I don't know how much you're familiar with the fat

00:01:48: as F1 teams we'll have representation table of technical discussion which is called a Tac meeting technical advisory committee and.

00:01:57: In that meeting

00:01:58: my steam has a representative where effectively during this year has been more prevalent than I recall having done it for the past 506 years where presents has been prevalent in the sense that we've had to be particularly particularly engaged with ensuring that regulations involving a kind of sensible

00:02:15: executable rational manner from demands of increased safety from demands performance from demands of race ability with you know the car following Argos which I'm sure we'll talk about it later so

00:02:27: that has a Blue Dot on my time this year and having that role means

00:02:31: the interface in terms of technical functions with all of the group the design office the department is quite live in terms of interpretation application and utilisation of reg they presented to.

00:02:44: Quite very grow because this and I suppose haven't done it for as long as I have I kind of Dublin as many things as it is need

00:02:51: we're a small team we have more demands upon individuals because we need to get these things done some things might split my rolled into three or 4 in a particular task that can do that you've got a lot on your plate then.

00:03:03: What's your organisation like now at what's an error department night now at us how big is that we've got 22

00:03:11: and they just beards and ever since then we've got a safety group that is 8 people who are basically doing methodology developed

00:03:20: in this applying tool sets that are available to audio services then there are.

00:03:25: Group of model designers that support the analysis obviously we don't have the burden as a team of having the wind tunnel support staff because we went the windowsill 80 and all the support infrastructure is there for

00:03:37: to allow us to do that so we don't have to do maintenance and then all those kinds of tasks so in terms of operative elements that develop the car.

00:03:47: On the dynamic side we're talking about 4045 people with respect to then on the designer side then we've got a group.

00:03:56: Designers that are both here and Delara variably go from 35 to 70 so depending on the time of the year different scale though relatively small wooden

00:04:08: what's the size of the Development Team lioness and where are they based how is grown in recent years

00:04:14: our Development Team isn't a finite size as it's always going in line with our customers needs and our own leader further optimise our product offering we haven't signed order find a number to how big the team should be if that makes for each project that requires devil

00:04:29: the complexity of the work scope and an appropriately sized team is a sign

00:04:33: I think the main thing is that we always try to find the right brains if you will for each piece of work which means that often our team are both cross-functional and cross location

00:04:42: we have dad's contributing from across Europe in Germany Romania Spain UK and further afield this recent shift to work in virtually inputting the right turning in place to do so has really opened up the process of working with the right team for the task

00:04:56: Ben describe just to race cars that can by race weekend that how many people law clients and servicing with that set up you just describe

00:05:05: yikes I'm honestly not sure you can compare the two organisations fairly with creating only two products the Cartwright and there's Christmas

00:05:13: perfectly over a 3-day weekend during the week run longer breaks between races the team can and repairs or optimise a car for the next race.

00:05:21: Ariana's we have over 18/2 million customer contracts and each contract is basically a separate project with a specific

00:05:27: and spoke requirement based on the customers needs right it could be a simple website or an email server or even a really complex cloud instance and we have to make sure

00:05:37: all of these different and products are available every second of every day so of course it is imperative that we provide 24/7 customer support from technical experts

00:05:47: and we also have to think about things like always provisioning enough infrastructure and power does supplier customers at a moment's notice when their techniques grow so just having everything on hand and planning head

00:05:57: 18/2 million customer contract huge bloody so much today.

00:06:03: Ben is incredible how much it's grown in that period that you thought about I mean that was a sound like a lot of people to deal with an a lot last text to there was so what is your day-to-day job look

00:06:13: what's a typical working day look like for you if there is such a thing certainly here as well with sat in Maranello Warehouse a base alongside Ferrari so I guess that helps on that aspect being right here to Leverage that part

00:06:24: obviously one key part of my role is

00:06:26: engagement and maintenance of a relationship in terms of the technical interfaces that we have to have with Ferrari when we doing installations

00:06:34: powertrains and what are known as the two are Caesar transferable components that were allowed to have daily we need Norwegian awareness of how their revolving in the Valley Integrated with our car

00:06:44: so there's a relationship consume sometime in order to maintain awareness.

00:06:49: Understand also how things are Rolling because it's specially in the Year Like This obviously things are changing quite rapidly as things evolved on their side and we need to keep.

00:06:58: So that's one keeper

00:06:59: the FIA as I said from time to time can be a dominance of days because the amount of work that needs to be handled if you like prepare and be aware.

00:07:09: Of reading at home with regulations becoming familiar with that we're still happen everyday at 11 months.

00:07:15: Because it's evolving and changing and obviously there's a lot of interpretation underlies it so I do this sometime in trying to mature understanding and

00:07:24: Delvin to interpretation which I can then sheer in regular development discussions that we have with the department or the design department often I'm tap

00:07:34: frequently by all the guys in the design office on in there with respect they would you think of it and can we get away with that and what would you do here and how can we justify that and they're good because they insight that exchange of.

00:07:46: If you like sensitivity that we have for the nature regulations and experience and.

00:07:51: Free thinking ideas of people that aren't burdened by my history you know by their own so I think that's if you like the main functions that individual and then they are much more combined aspects of my role

00:08:02: with Simona Leicester

00:08:04: there is if you like strategizing with respect to what we might be doing in a medium term with Business Systems about that we were relatively new design group here introducing new design tools and put that management tools.

00:08:16: And these things need thought planning strategizing in terms of introductions they don't impact what we do day today in a negative

00:08:24: if you don't do them you building efficiency into a system so we try to maintain the thought of how to extract value in Continuum from the group of people that we have and you talk

00:08:33: between here in Maranello it's a new setup that needs in the last 1230 months it's really come together so it's clearly sort of an evolving situation here.

00:08:42: A big Tesco handset only this year with a brand new set of regulation so let's talk about the actual challenge of designing a Formula 1 car you don't start with a blank sheet of paper.

00:08:52: Draw the fastest thing you can what's the framework you start with where's the starting point for someone going right here are the new regulations whose come up with those and how do we then turn that into a conker more than ever

00:09:04: I think they probably

00:09:05: all without exception of the 26 or so years that I've worked in F1 I think every year has had an element of evolution from previous knowledge that you brought from previous year accumulator

00:09:18: and therefore you had a basis of a concept that you were going over even when cars went 98 where we narrowed the cars from to my 1.8 even though

00:09:28: yes it was a massive accidental change but really the underline concert wasn't different this set of regulations is completely different and it is much more you know I would do analogies with indicators for example that I did in 2012 that was an IndyCar that if

00:09:43: that was a clean sheet of paper that was a an aerodynamics is saying how do I get the most performance out of a platform that I don't have regulations

00:09:51: and it was quite easy and the impact is that you spend less money achieving a given performance that will because you're not constrained this set regulations has similarities in the sense that uses the ground effect of the underbody so that he can experience if you like is put into the pool so those of us and I'm not alone and Melvin who's head of Arrow you know who's got a lot of expertise worked in that world as

00:10:11: and so I think between us.

00:10:15: Basic architecture had some fundamentals that we thought we're necessary then you look into regulations in more detail

00:10:23: at that stage you're not absorbing everything that is being

00:10:27: imposed upon us restriction then the availability of the evolution of regulation means that you build a picture in CAD in your mind.

00:10:35: Of where your restrictions are and those ideals that perhaps you know off by their coupling of wing elements camera of under bodies level of diffusion

00:10:44: coupling of Apple wings with diffuser those things you have some home truths as a technician and somebody you an engineer who has a basis.

00:10:54: Whether you can implement them in Context of regulations that have been also designed by engineers.

00:10:59: And obviously trying to preclude you from doing so then you're in that kind of cat mouse how do you get what you want in context of what they're trying to preclude you from

00:11:08: stop quite as black on my lap but the evolution that really proceeds in that first phase and we talking about back in probably November October November 2020 is really that cohesion and regulations were not converge.

00:11:22: So you're doing work you're running cfd and then you went back to their phone is I don't really want to do it like that you want to do like this because you're trying to push your own agenda

00:11:30: they come and get it but then they don't and so you're getting there's a little bit of training there and all teams are doing in parallel so it is quite an organic kind of convergence eventually you put something down she's what you think is your best guess

00:11:44: and it is clean sheet of paper.

00:11:46: Is biscuits because this is a car that you haven't designed before it's got different characteristics that you've never seen before was a bit of IndyCar is a bit of GP2

00:11:55: as it was and the front wing is I don't know it'll be in the car that is probably 2014-15

00:12:02: coupling them is not something you've done so you'll have to try and that's what they were you see it and we use really the early work was all cfd it was all the proof of concept the estab of interactions the understanding of flu

00:12:17: regimes and then that's when the difficulty starts because once you have a basic viewpoint of something Would You

00:12:24: feel is a coherent concept then it became something that's much more complex because then there's a questioning of actually are your suppositions correct as you use some kind of.

00:12:36: Intellectual bias to say I started somewhere and the most difficult thing to encourage people to do

00:12:42: is to say yeah it just cos we've sent that now throw it away does now we have to question what it is that we thought we knew and so you start down that path from that path is a coupled exercise between.

00:12:52: Safety as a simulation and wind tunnel as a simulation one correlating the other we don't have the advantage of being able to run in full scale so we have to learn that correlation aspect which we gonna learn in the next few weeks

00:13:04: with the experience of what we expect to see in those regards we use a lot of that combination of knowledge

00:13:11: the all of us have to take the best position with what we think is going to be the best compromise of choice of type of loadings type of interactions of flow there really the prime arguments that have been in the first phase of the

00:13:25: doesn't sound like it's a very linear process it's not it's a very kind.

00:13:30: Iterative review critiques self critique and eventually you get something when you think ok I think we've understood the basics now week.

00:13:38: Stabilizer platform ingenuous to start thinking about installing all the bits that you need to drive a thing so the powertrain comes in suspension kinematics come in and all these things need to be

00:13:48: integrated in parallel to the critique which is the aerodynamic concept permits you to package call and pursue performer

00:13:56: do you ever get to appointment having a whole car on a computer screen where you like that's are Concepts that working with or is it

00:14:03: developing different sections and pieces always have a car because the cars too heavily too much and interactive devices even though we evolved and you'll see how we've updated the front wing.

00:14:13: That isn't just you know done in an isolated man ate everything is always around a base concert right now we have a bassline.

00:14:21: Which we've released the car that will run at this one.

00:14:24: And that's all reference and that's been detailed impact and characterize and has all the characteristics of cooling and wind levels and and that's the baseline on which we evolve and evolved incrementally on that so it might be a floor development development or have

00:14:38: there's always a status of a car characterisation.

00:14:49: Is it all happening through cfd at the stage no I'm very early we would have until probably February of 2020 was only cfd.

00:14:57: But after that it was very heavily went on as well so we're doing both programs and you know from going to sold you that we had a discussion back in October November 2020 where we

00:15:08: really 21 we know is going to be a sheep and so we need to turn our attention to that you couldn't

00:15:15: we know that we have to turn our attention to and we've got a finite budget and we need to make sure we put it to best use so we go

00:15:24: immediately end of the year and isn't the clarity of structure of the team only really happened over Christmas of 2020 so we came back in January and we really had some plans in terms of establishing the function and

00:15:38: you know building a model 422 car and so just for the latency associated with that meant that we got going probably mid February so when you start then that's what the process in a bit then putting a win.

00:15:50: Model into the wind tunnel so you

00:15:53: the regulations evolving your trainer interpret them you've can't with what looks like what we will assume is the Formula One car on a screen on a very technical screen then involved with them taking

00:16:03: and creating something to run in the wind tunnel to get different results and how different are those results are important is that

00:16:09: in terms of number of people having all the people I just described previously the Beginning everyone was involved at the beginning of the year because if you think the detail associated with defining physical components the whole car you're not doing updates you're doing at home

00:16:24: a lot of work a lot of Resource and also is a lot infrastructure that point because the underlying the bodywork

00:16:31: scale modellers infrastructure that was previously pitched at old regulations that needs adjusting and modifying and Times of operation Lee that the model

00:16:40: has a functionality of load measurement and pressure measurement which was the same as not really had to read all that.

00:16:48: In terms of dressing it with one of the changes examples quite a different floor to the diffuser last year's has been flat the floor is it.

00:16:57: Where is she all of the floor is a moulded surface

00:17:00: that means you can't necessarily afford to say I'm going to make it out of a plate of aluminium because how do you form it you gonna machine now solidor

00:17:09: mouldy in carbon all of those things need to be considered and that's part of the if you like the KNOWHOW of the team to know how to engage different materials and achieve development ability within a 2

00:17:22: developmental language.

00:17:23: 7 six weeks or so to get a process of a kind of a launch surface in cfd if you like that you think is a good place to start

00:17:32: and have a winter model operative that's quite a long time in the grand scheme of things isn't that is a long time but I'm talking about a process that if you like is not time-critical that point we can see if these dominating

00:17:44: and clearly we were in a phase I mean I think in any case you'd be talking about 4 weeks for a complete model because

00:17:52: you're talking about a capacity in a model shop that's finite and designed and scaled and budgeted for development ability when you have to encourage it to the vet.

00:18:01: A complete car you're making

00:18:03: all of the instructional design stays and supports for floors you're doing all this extra work that you wouldn't normally do when you're just doing a new one

00:18:12: and later down the line you do it once you're doing it every week

00:18:20: then it doesn't stop the machine but when you're doing that model that is a realistic amount of

00:18:25: if we linking actually honest partnership here how much of the info that you're then gaining both cfda gases may be easier to share the results of.

00:18:35: By the cloud or with the different members of the team yet being a team that split over so many sites when it's winter the work is that a trickier process or is it almost more important than to rely on something that can only take place in one set location that you don't have to share the results of.

00:18:50: Across the multiple sites yeah I mean activity and the connectivity that we have between us site permits absolutely real-time transfer of availability of data are also.

00:19:01: So for the first five 6 years of our existence we had the safety group in the US and I'll plaster was in the US.

00:19:08: We had to rely on launching cases from Italy and receiving data from the cluster so that was heavily dependent on bandwidth

00:19:17: I'm not saying it was perfect but it works for that amount of time now we still have our cluster in the US.

00:19:22: Our all about functions without technical functions engineering function is here so we still launched cases in the US and then we receive data which we now

00:19:31: with increasing bandwidth has increased over the 6 years in a position where guys can see a turnaround of cases in 45 hours

00:19:38: and see results and that there was also been generated in the US so you know what should be a real big limit

00:19:45: be better if it was more efficient but there are reasons for the way that we're organised we're able to use those facilities regardless of where they placed overseas part of our structured hasbeens.

00:19:56: When is moved onto the winter model and you

00:19:59: what's again I Madison evolving with 90% regulation so I think that's fascinating that is still 10% now been defined at such a late stage breaking up with me if I think it's remarkable that is we talk

00:20:13: a brand new car come into being inside that's still

00:20:16: but you said about updating and how much quicker that can happen how regularly are you going through a process

00:20:24: ok we set this is our starting point and when did you reset your starting point of ok with committing to this is our car and now from there when you can

00:20:31: you're talking about now releasing freezing the car that goes to track the full scale car.

00:20:37: And yeah that the process of release we call it from the arrow world into the design world and therefore production starts really in

00:20:46: no she coz the chassis for example had an immense amount of increased attention demand by virtue of the regulation changes that imposed much higher safety

00:20:58: requirements demand structural demands on the chassis so they needed more time to be able to do project work design testing and song that she would have been released back in September at the Monica and then from there is a scale.

00:21:11: Kind of release process that runs from September until pretty much Christmas few releases straddle for us post Christmas

00:21:19: things like brake ducts and devices that what we consider retuning like floor edges rather than the body of the floor body and floor may go to design and be frozen in that regard.

00:21:29: In early December and then it's a gender fences or have you arrived in for in Jan.

00:21:35: Then you're giving a production process of design and production process time to Stagger the design process from September to Christmas and then production it's really working off saying 8-weeks cycle or 10 weeks the floor for example achieve delivery of components as they are arriving in these weeks now so

00:21:53: can you show the stage is nice and clearly actually

00:21:56: going from design idea sealed it off ok that's what we're gonna go with sending it nice to dallara not in all cases that we're organised this split between the lower and

00:22:06: and the division of certain areas of the car some has been managed to your son

00:22:13: manager that has needed to management as well to ensure that the communication is transparent and the referencing of working of common references for cad models is this.

00:22:23: That's needed some established traditions design between the lower and middle and then the release of components to production is VI.

00:22:31: The UK office because the pmo group and all the purchasing group is in the UK and they distribute what isn't made at the Lawrence some parts are

00:22:40: I made with a lot of manufacturing companies in the UK that's managed that's what the UK is doing apart from housing race.

00:22:48: International card and it's coming together when you do that and I mean if we had 45 hours to do the podcast we could go to each component and sort of the what does Domino's but one key part I won't speak to you about that you mention the chassis and releasing that now for

00:23:02: many isn't maybe don't understand the differences or the actual constraints of what that means that's a said she the safety cell monocoque that the driver sits.

00:23:11: No wings nothing like that that's when you strip the car back to its most basic form.

00:23:15: And it looks like a little tub how can strain the you for that design on how creative are you being even with that component

00:23:24: need to me because all parts are linked and so considerations in terms of full particularly on the underside in terms of interaction with the floor is important to consider having said that heavily constrained as a design because its prime purpose is the safety of the driver and so there are.

00:23:41: Minimum section templates for the apertures minimum sections for the walls that are around the drive

00:23:47: the tube if you like the bit where the driver's legs and pedals are is a volume allowance in which we can define a shape which is of a given certain size UK

00:23:57: very the way that size evolves in terms of its side view for example bed sections have to follow a certain dimension one of the parts that is if you

00:24:05: important developmental point of view is that the roll hoop does the roll hoop behind the driver needs obviously to satisfy the structural requirements in terms of roll over.

00:24:15: There is also a keeper in terms of feeding engine and feeding other cooling requirements in terms of the intake and its shape with respect to his quite a blockage element head of the rear wing so it does need to have parallel with what you're doing downstream

00:24:29: but you tend to kind of have to focus on those items earlier in the process.

00:24:35: And make decisions because you need to release those items earlier knowing that there's a big elite I'm in terms of design

00:24:42: what is the L on the chassis that because that's what I mean huge be to come fibrant is it one bit generally made into parts and it's split and bonded to open shells and delete is really this you more than ever

00:24:55: there's been a longer lead time in design because of these increase

00:25:00: safety requirements much higher loads on lateral boots for example chassis has to resist a certain enormous 350kmh of load over a pad of 200mm of it's kind of size not sustain any damage so it's all part of that kind

00:25:15: increase cocooning that's been demanded and it's all motivated that need

00:25:19: some clever structural design to ensure that was attainable with minimum weight because obviously

00:25:25: you heard Simon and talk about way already that is a challenge for us because all these the increased demand for safety is adding way even though we're trying to make these cars you know

00:25:35: performance as possible which is a bit contradictive at requirements so that the chassis the chassis has had that increased demand design-time this year which is why we had to be a litre.

00:25:44: The head of a processor released and probably had six or eight weeks associated with just definition and sample testing and this kind of thing and then.

00:25:53: Inevitably this is what we call a dummy chassis that dummies JCB.

00:25:58: Represents if you like Anna Causeway what you're trying to attain in terms of its structural performance you're not too worried about his consistency from an arrow performance

00:26:07: and then the real chassis then follows it before chassis and then we end our first chassis for end of the for Christmas so that was a process that was about 3 months but then the other parts on see it's a shorter lead time you said about the constraints on the chassis in general.

00:26:21: How much freedom do you feel you have

00:26:23: when you're designing F1 car to chase ideas to create what you want to create and how much is actually just responding to and trying to find ways around constraints it is it the latam on the

00:26:34: the question

00:26:35: the answer isn't it might seem is clear everybody spoken about the fact that these regulations much more constrictive constrictive in terms of trying to attain a particular target of week but within those restrictions of which they have always been restrict

00:26:50: there is still margin for individual application and interpretation

00:26:55: the interpretation of the regulations but also in terms of application of services the difficulty is

00:27:00: has the regulations become more constraining you will put things in this face you will have it look like this then the work that you're doing as an engineers and aerodynamics this really much more fine and much more refined in terms of what you do with local services

00:27:14: and services interaction and that means development cost time and money is higher because you're changing bulk Services when you divert.

00:27:23: When you got a wing that has to look like this but there's infinite freedom within boundaries of incidences of profiles and have you then you can't prevents on anymore to tune what you're trying to June in terms of wake you have to work on

00:27:36: can you make a wing You Don't Cost nothing wins cost a lot even autoscale it's a little bit.

00:27:43: Contrary position when you're talking about budget cat world where someone controversial you're giving regulations end up costing you more to develop the mod.

00:27:51: When is also we find out do you ever find yourself saying down with a pen and paper and just getting out an idea thinking in that way or is everything else so complex that you have to be doing cfd like working on computers much much much more engaged with

00:28:05: viewing the car within regulation context on CAD because there's much more details consider than just if you like the base idea

00:28:13: there's still space for that imagination and that kind of self interpretation which often you come up with your dinner you worry about that you can legalize it later because otherwise if you can strain the mind too much then

00:28:24: you're not thinking as a free spirit you're thinking as a machine and we don't want to go to do that they need to be

00:28:30: down the process you've got the car you've come up with a base design you've release date you started doing updates at which point do you.

00:28:38: Stop paying attention to the process of going on if ever and keep just thinking of your reverting back to write how can I improve that part and go back into the design aspect or are you looking at the end result and seeing it on track and having to reactive that

00:28:50: yes all of it is relevant there's nothing has more weight than.

00:28:53: Because ultimately the car is what counts the problems of the car on the track is what counts if there are things that we need to learn in terms of how the cars behaving say Aerodynamic

00:29:03: is the reliability which is a

00:29:05: tangible reaction that demanded of the process by which we talking about performance of saviour returning platform there are going to be lessons that we haven't yet learnt because it's a different level.

00:29:15: Correlation that we can be experiencing a full-scale things that we have to adapt and we've already design experiments that being able to do

00:29:22: once we have that that throws itself that kind of invents itself into the mall standard development process

00:29:28: and is equal consideration given to correlation lessons learnt and developmental ideas and tools and you know Business Systems because everything builds efficiency in our understand the efficacy in terms of implementation

00:29:42: there isn't an exception everything runs into so many how often designers have to look at an overall product when developing it or are you able to update things in a much more small specific areas more regularly have a definite advantage compared to an F1 car

00:29:57: and I honest we use agile methodology to launch new products simply explain this means we launched a new product at a really early stage in its development.

00:30:06: When it's what we call a minimum viable product kind of the minimum working solution acceptable to roll out to early customers so after the initial rollout we then use feedback from those early adopters to optimise a product even Redefined the last text.

00:30:20: And then we do the same all over again basically with every refinement and roll out a new features we launched gather feedback refine lunch together feedback

00:30:28: and in this way we continually improve the product until it eventually has all the features

00:30:33: a required this is also really nice way to break a project down into chunks to allow us to focus on different aspects of the product so when we can focus on security the week after we may look

00:30:43: implementing a better user experience and we get with that may be all about making the product powerful or faster.

00:30:50: Play the 11th Mick Schumacher is that on that track the car has to be 100-percent perfect in every aspect and King get a Merlin attraction say sorry dude your steering wheels a bit about what I call that next

00:31:03: and then when you can get an end result and you've got a car that your roll out which we

00:31:07: does a Volvo season sunny this year they'll be a lot of updates the car no change very much from the first to the last race to some degree

00:31:15: when you looking at deuce look at something and think that looks beautiful it's going to be quick or do you care what it looks like or in your mind is the only thing that matters is a

00:31:23: yeah the only thing that matters is the stopwatch that's what we said we get points for but he lying to say that there isn't an aesthetic kind of appeal and.

00:31:32: You know often implementation and Adrian used to say to me pretty version

00:31:39: something that has equivalent value don't go for the pretty version so yeah of course we have to somebody's then.

00:31:45: So I think there is an element of that but no the song which is what Council is from that very first car that you create and start from

00:31:52: when you say ok we're working for this point from first getting out finished current screen to getting it on track to rent for the first time how long does it take

00:32:00: that is a somewhat every cos I mean I described earlier that the chassis has to be released before

00:32:06: anything Virtuoso there are releases that evolved during the release process

00:32:11: aren't associated with the definitive College vintage car converges in the January but start being released

00:32:17: in September so I suppose the evolution to have that bass line on the screen that you asked for is from September to January from having parts of that release into production probably run from November.

00:32:29: The February they kind of superpowers it's not that you say I finish the car now I release it it has to be knitting with some bits have longer lead times but then I guess your first

00:32:39: iteration with September and the first actual car that you could run would be February and is that just to find my regulations and testing schedules and stuff would you take longer if you had longer or is it

00:32:50: would you have because you could definitely make the car better if you took longer but obviously working to a target so we have no choice.

00:33:00: Thanks for listening to drive digital success presented by iron on this was the final episode of the Seas.
