Hi, got to thinking, i think it whould make some sence.
for the tycoon part, if i was to make two engines both with a,the same bore and stoke one is a inline 6 and the other is a v12, whould there be some sort of parts sharing to save costs ? like the cyllinders, block and head? 
Yes, that would make sense, but we decided against it as this would lead to quite a bit of micro management we donât want to see in the game. You will only be able to build 1 engine family per engine factory, so there can be no part sharing between V12s and I6s like in your example.
How about just simply giving players a bonus to costs or production time? The way I think of it, then there would not be extra micromanagement. But it could potentially add a bit more depth in to the game.
How would that make any sense considering the â1 engine family per engine factoryâ statement in my reply? 
I know itâs de-railing the thread a little, but it follows on from the above statement.
Is âFactoryâ the right word to describe the production facilities?
Most real world factories produce more than one item.
E.g. FCAâs Plant in Melfi, produces Fiat Punto, 500x & Jeep Renegade. (3 models, 2 Brands) and their Termoli plant will produce both V6 and I4 engines.
I realise that physically these products are likely to be in different buildings but they do tend to be collected together as one âfactoryâ.
Would âProduction Lineâ not be more suitable?
BTW the Melfi 500x facility can be âtouredâ virtually here > fcamelfiplant.fiat.com/
Well for example, if straight 6 and V12 can in real life share some parts, then even though in game, you would produce them in different factories (or production line or whatever), you would still get a small discount for their cost per unit or something like that. Just because your company is building engines that can share parts with each other, even though this happens in different factories. You donât need to mess with factories, you donât need to mess with anything, just producing 2 or more engines that can share parts, and you get a bonus.
This could also be used in chassis, suspension etc⌠For example, if many of your models in lets say in 70âs would be using a solid rear axel, even though the models(and trims) are being produced in different factories, then you could get a bonus for using same kind of stuff. Just simple bonus, no need for extra micromanagement with factories or anything.
My two cents:
Maybe if there was a âbuild derivative engineâ tool where you go through your list of engines, pick an inline engine, and the game automatically creates a V engine family with all engine family settings locked. So if you picked an all-aluminum 86x86 MOHV I4, youâd automatically be given an engine family of an all-aluminum 86x86 MOHV V8 with reduced development costs or lower production costs for that family only, as long as you have the base engine in production. Perhaps the tool could be capable of adding or removing cylinders from a family too - convert I4s into I5s, cut a pair of cylinders off a V8 to build a V6, add a pair to build a V10, etc.
Even if it didnât give any in-game bonuses, itâd make building all those engines a bit less time-consuming.
That sounds a bit gimmicky at least for me, and it doest work when there are different V-angles. All im saying is that: âSo now your going to build another model with solid rear axel, ok so now it gets even more cheaper.â
Audi has 90 degrees on all of their v engines. (v6,v8,v10) Can be traced back to the first v8 they made.
The only v6 engines that is not a 90 deg. they are built by VW (VR6).
Killrob has already stated in the last dev update that the game will only have 60° v6 engines since anything else is inferior
To re-explain what Rob said, 90° V6s exist pretty much only because some companies find it simpler to just cut two cylinders off their V8s.
Compared to 60° V6s, they tend to be larger and more prone to vibration. And since their only advantage wonât apply in the game, there isnât really any reason to have them.
15° VR6s though could definitively be interesting though, as their are for the most part a middle-ground between V6s and I6s. Although since they arenât really used outside VAG, that would be more the kind of thing Iâd see being done post 1.0.
Correct. VR-6 engines would be worth adding to the game as they come with pretty big specific advantages (size & weight), but unfortunately they are a pain to make with the assets we have. So that would not be worth it.
I imagine the main issues are related to the head design being quite different from pretty much all the other engines planned for 1.0?
That and pistons, etc, there is nothing but conrods that can be reused
You cannot even use the conrods, on a VW 1.8 4cyl (81mm piston * 86.4mm stroke) the conrod is 144mm. On a 2.8l VR6 (81mm piston * 90.3 stroke) the conrod is 164mm.
Conrods are longer than the stroke on pretty much all engines, as itâs the dimension of the crank that defines that.
I think he meant art+calcuation wise in-game. The VR & W engines are a unique beast.
The conrods can be carried over, but the rest would have to be redesigned from scratch.
Thereâs several other (generally packaging related) reasons why youâd build a 90° V6, but I will readily concede that they are the exception, not the rule, and therefore not really worth bothering with for now.
