Engine cover fins

Post by eytl »

"Engine cover fins should be banned."

Discuss.

=====================

Anyone else think that they are utterly unsightly? At most, allow fins of a certain dimesion, eg Mercedes, Lotus, Virgin and Williams. But not the full length ones that stretch all the way to the rear wing, a la Red Bull/Toro Rosso, McLaren, Renault, Force India, Sauber and now Ferrari as well. The rules have already managed to outlaw all the little winglets here, there and everywhere which made F1 cars sprout like broccoli, why not these monstrosities? People accuse F1 cars of being moving billboards, we don't need that taken literally.

And, just to prove that this ugly concept is actually nothing new, I present exhibit 1, the 1972 Ferrari 312B2:

Right with you. I'd imagine that they'd be like the twirly wheel covers, unsightly for not much gain.

Though don't try take away a slight privilege from the teams! God knows what would happen without those? The engine might fall off or something!

A ban would get my vote. They take away the distinctive shape of a Grand Prix car, or any single seater for that matter.

We wouldn't want these trickling down into Formula Renault would we?

I hate them, they ruin the whole car. I can remember Mclaren using one in 1995 as well so it's been tried before. The point is, GET THEM BANNED!

We complain about how cars all look the same, then try to ban anything that we don't like thus making them look more and more similar. I always liked the little flip ups and aero details, they made the cars more distinctive. If we ban engine covers and continue going down that route, we might as well take a cue from NASCAR and introduce using the same cars for all teams. Formula One is an engineering competition just as much if not more than a driver's competition; but with these days there's precious little room for innovation. Why ban something so innocuous?

i also think no shark fin at all is the best but a complete shark fin looks good on some cars
i find anything in between ugly

Hm, I believe that the reason why those pre-2009 winglets were stripped has partly to do with aesthetics... it was probably the reason why (also) those distinctive x-wings were banned more than ten years ago... but then, no-one banned the 2009 Renault because of its (utter lack of) aesthetics...

I don't think you can reasonably ban entire cars on the basis that they are eyesores.

Agreed - given that the regulations are restrictive, there are complaints that the cars are too similar. However, once Newey comes up with something different, we get the predictable complaints that it is ugly, or that we are seeing innovation in the wrong areas and so on.
Personally, the actual function of the fin itself is quite interesting. In the case of most teams, such as Red Bull, the idea is that the fin redirects airflow over the wing during yaw (when the car turns), improving the efficiency of the wing. There is an interesting debate about the Mclaren engine fin, however - there is all sorts of speculation that the fin may have an alternative purpose (mostly revolving around using it as a duct to blow air through the gap between the wing elements, to prevent the airflow over the rear wings from detatching prematurely).

I'm afraid I have to agree with the above two comments. I don't care how beautiful the cars may appear today, I am not massively exitced or interested by today's F1 car designs, simply because they are all the same IMO. If you take away sponsorship & liveries & painted all the cars in black, I bet the average fan won't be able to tell a Red Bull from a Ferrari for instance.

Whereas I was interested in F1 car designs in the late 70's early 80's when F1 cars all seemed to differ to one other, & that made it another exicting aspect of F1. For example, some cars were turbo powered, some weren't. Some had front wings whereas some didn't, or the rear wings supports where different. Then we had, the Brabham fan car, or the Lotus 88 (the twin chassis one that got banned).
The fact that late 70's early 80's F1 cars were "ugly" in appearance really wasn't a big deal when you considered the better racing it produced & the extra interest it generated as a result (i.e amongst F1 fans in assessing the pros & cons of a particular car design). It was IMO another talking/debating point amongst F1 people as to where one design worked over another.

So If I had the choice between beautiful looking cars but no difference in designs. Or ugly looking cars but a difference in design (therefore a another talking point to consider). I would happiliy choose the latter.

I like the engine cover fins. I also like wings, winglets, NACA ducts, Gourney flaps, shapely surfaces, Mansell moustaches and all the stuff they banned in 2008. The more intricate the better. And add in a chin spoiler under the wing, just in case.

Interesting story about the X-wings: http://www.f1fanatic.co.uk/2007/04/05/banned-x-wings/ I find the fact that they were recycled old wings at the beginning hugely appealing. I don't know why...

To be honest, quite a few cars in the late 1970's were direct copies of each other. Take, for example, the following:
Image
Image

In fact, since cheating and copying was quite prevalent in the 70's and 80's, we know that many of the teams were simply copying each other's chassis designs (particularly throughout the ground effect era). One particularly good tale is as follows: after one poor practise session in 1981, Chapman was having an argument with both drivers over what was the problem (they were arguing about the rocker springs, dampers etc.).
When one of the other engineers intervened, Chapman told him to go out and measure up the Williams FW07. At first, this engineer laughed - at which point, Chapman said "Either you measure that car, or start looking for another job." Now, this engineer came across one of the FW07's, which has been recovered by the marshall's after Jones had spun off, and was waiting to be picked up by the Williams team. Dutifully, he masured the car's track and chassis, and duly returned, only for Chapman to complain that he hadn't measured the rear suspension. Back he trotted off to measure up the car, only to be caught by Jones whilst he was measuring up the car. After a brief altercation, Jones sent him on his way, having given him an earfull. At the following race, Jones then presented the Lotus engineer with a builder's rule, with the following warning on it - "You can use this, but don't get caught doing it again."

Equally, whilst the Brabham "fan car" or the Lotus 88 were innovative, they also had the major problem of being banned pretty quickly (in the case of the Lotus 88, that never even raced against it's rivals), so I wouldn't use them as the best examples. And whilst technical differences may have existed along the way, very quickly one particular design would dominate, much like today - turbos drove out the normally aspirated engines, wing cars soon beat non wing cars. Moving forwards to the early 1990's, the V10's drove out the Ferrari V12 and the Ford V8, and so forth.
As for beter racing, yes, perhaps, but equally you could say that in some ways the past seasons have been as repetitive as in recent years. As was pointed out when Button won the title with Brawn, that was the first time since 1978 (when Andretti won with Lotus) that the WDC and WCC went to somebody outside of Mclaren, Ferrari, Williams or Benetton/Renault.

Also, whilst you moan that all of the cars look the same these days, I would disagree with you. Taking a look at some of the technical forums, and seeing the pictures of the cars, you can see that whilst they may appear to be broadly the same, once you start looking at the details, you realise that they are all different in subtle ways.

If cars are going to evolve, maybe the fin is the next step in its evolution, I remember my grandfather LOATHING the cars of the late 80s, because they looked nothing like the cars of his time, where "you could see the drivers arms", and in the insuing bombardment of safety/aero regulations, you can hardly see the drivers head anymore.

MHO its ok to have the "fin", but i see it as too much of a change when they extend that fin as far as the rear wing, lets just hope that F1 cars in the future dont end up looking like the deltawing concept.

What I don't understand about that concept is how they expect it to turn with the front wheels so close together. That wouldn't work, would it?

In a few years time the shark cover fins will be old news and a team say Red Bull will find another engineering invention and teams will moan and complain (2009 Diffuser issue). To me Formula One has to many rules this and that. Same with engines just V8s. I wish that the FIA open the rules a bit.

Exactly. If Indy is going to be a one-chassis competition, that chassis better look good. There's no interest in the A1GP or GP2 pr F2 cars much, for the reason they are all the same and look pretty bland.

That's one of the reasons why I like the WTCC, with all the different bodies and engines. Now they want to standardize the engines. Mmmm...

I think the BTCC is one year ahead of the WTCC in standardizing everyone to use the 1.6 turbos. The same engine, incidentally, is bound to go into the WRC as well.

I thought that the WRC were going to switch to something closer to the S2000 regulations instead (where they currently use a 2 litre normally aspirated engine) in order to cut the cost of producing a WRC car. After all, the problem is that the WRC is also suffering from the withdrawal of manufacturers (one car alone will set you back around €700,000, and that is before you consider the cost of the support crew etc. - small fry compared to F1, but still not a trivial amount). And let's be honest, the WRC has been a little dull as of late, because it has been pretty much a Citroen - Ford battle of late, much in the same way that often the F1 championship has been a Ferrari - Mclaren battle.

And let's be honest, the WRC has been a little dull as of late, because it has been pretty much a Citroen - Ford battle of late, much in the same way that often the F1 championship has been a Ferrari - Mclaren battle.


The idea is to substitute both kinds of 2 litre, atmospheric engines currently in operation in the ITCC (S2000 regs) and the WTCC engines of the same kind with a 4-pot, 1.6 turbo unit. The WRC and the ITCC would more or less merge in terms of regulation (there's talk of merging the Championships as well), WRC costs would be cut by limiting development. Future WRC cars are currently in development: Loeb and Sordo apparently tested the upcoming DS-3 WRC (still equipped with the present, 2.0 WRC engine) last week.

The idea of using the same engine rules in touring cars is to cut short SEAT's advantage (TDIs have led the field since their inception, leading to endless discussions, regulatory coups and threats of withdrawal), in the WTCC case, and to cut costs, in the BTCC case. The British actually propose the regulator to offer a "standard" engine that teams could buy at a lower cost, should they decide to, instead of manufacturer-developed units. Standardization, power-eggs all that. They may have a point; note the travails team AON went throuh this year to develop the engine for the Focus, and you see why the idea is tempting - even if it thwarts diversity.

A Turbo 4-banger makes sense to me in the WTCC...most of those cars come standard with at least a 4 cylinder, it might not be turbo'd but Most Cars in the world are 4 cylinders, and I'm surprised by the considerable number of people who don't realize that.

While I agree with all the love for technical advancement and diverse solutions, I still believe that the main reason we're in this mess in the first place comes from stupid rules. The rules require a larger engine cover for no reason other than to increase the real estate available for (now scarce) sponsor logos. If teams had the option to go back to the smaller solution then the hideously fused rear wing/engine cover might not be as attractive. Either that or we'd see even more variation in designs--a win-win solution. While we're at it we should eliminate the rules that mandate increased rear wing endplate sizes, too.

To shuffle the pecking order I'd come up with something nobody expects.
For example 'Next year no Airboxes and/or sidepods will be permitted'
Then we would have a very colorful, and in some cases probably unsightly grid. But I'd think racing will be brilliant, on and off track, and reliability wise. :D

I apologise thalion if I end up driving this thread off topic again by mistake. By the way, can you explain where this "requirement" for a larger engine cover to increase the advertising space for sponsors? Or is this based on personal opinion? After all, there are still teams which don't use the shark fin engine cover - Force India and Williams don't (I'm excluding the new teams for now, since they probably lack the data to decide whether it is worth it). Besides, some of those that use the shark fin don't use it all of the time either - remember that Ferrari used one a few times in 2008 (mainly in practise sessions), but Kimi prefered to use the standard engine cover, particularly at China, because he found that the car became unstable in high cross winds.

Anyway, it is true that the reason that we end up with such devices comes down to the fact that we are dealing with a highly regulated sport, which doesn't permit other alternatives. On the other hand, the FIA faces a balance between keeping the speeds down, so that the safety requirements don't become excessive (both for the car designers and the tracks), yet providing enough scope for innovation. Simply opening up the regulations without limiting what the teams can spend, or what they can research, would lead to an almighty arms race where the wealthier teams would have the advantage of being able to outspend the smaller teams and run many parallel research projects at the same time.
Equally, now the FIA wants to push for more road relevant technology, particularly for the engines, yet only a handful of teams could ever see the benefits (Mercedes, Mclaren and Ferrari, in terms of high performance engines, and possibly Renault for more commonplace engines) - yet those teams would also have to bear the brunt of the development costs, with no guarantee that they will ever see a return on their investment.

Then we would have a very colorful, and in some cases probably unsightly grid. But I'd think racing will be brilliant, on and off track, and reliability wise. :D


Although changes in regulations can benefit smaller teams in the short term, in the longer term, there is an argument that perpetual changes in regulations would hurt the smaller teams, because they are unable to keep up with the development capabilities of the larger (and much wealthier) teams.

A bit of a dumb question considering how advanced this thread is already, but do those fins give any kind of aero advantage? I don't think so, but I'm no technical expert.

Me neither - but put it this way: would teams assemble such a large chunk so far up if they thought it didn't? I don't think so...

Did those dumb winglets cars had up until 2008 have any aero advantage? I think it could be just paranoia.

I'm led to believe they have no advantage in a straight line but they can offer a little more grip around corners. I read somewhere a while back that the ACO were going to introduce them on LMPs as a way to combat cars getting airbourne when sideways.

No need to apologize. According to f1technical the aforementioned changes to the technical regulations were made in 2004 for the reason given above. I remember this because this was the first time that I recall seeing a technical rule changed purely for commercial reasons.

As far as I know, you are correct - as I mentioned on the first page, the idea is that the shark fin should improve the performance of the car when in yaw (i.e. turning) by modifying the airflow over the rear wing, and preventing it from stalling.

Thanks for that - I guess that since it was quite a long time ago, I'd forgotten about that rule change. However, although the rules might have mandated that change in the engine covers back in 2004, surely the regulation changes at the end of 2008 would have rendered that effectively void? Besides, with the wheelbase increasing on several cars to cope with the larger fuel tanks, surely the engine cover size is already larger anyway, and so the rule isn't needed?
