Answer my silly question?

[Royce44]

Ok so with the whole pollution bks and manufacturers forced to reduce emissions, this is leading to the demise of big capacity lumps like v12s and v10s leading to smaller turbo engines.

Now, my silly question is why don't they make engines smaller but with the same amount of pistons. For example, instead of producing a 3.0 v6 with turbos, why not a 3.0 v12 with turbos, apart from the extra manufacture of manifolds, nothing else is changed, just smaller.

So in theory cheaper to manufacture, smaller in size, similar weight?

Go on, shoot me down!

Ps imagine the next astra with a 2.0 turbo v8 B-)

Surely that extra cost wouldn't be as much as expected.

In my simple mind, A 3.0 litre v6 needs 6 pistons at .5l each.

A 3.0 litre v12 would need 12 pistols but only .25L each. So whilst there is more parts, there smaller so the same amount of materials.

Offset that further against the fact a v12 may sell better than a v6 model may warrant the extra price

Looks like I was right in thinking it was silly lol

Max torque- thanks for the science part. I actually wondered if the size of the cylinder was to do with some kind of optimum volume for ignition but didn't think of the friction etc.

Thanks all
