Theres a yellow Golf round the corner and on the back it has a red badge marked V5. Is that really the engine configuration? Just seems a little odd! (Bear in mind I know little about engines but wish I did!)
VW used a VR5 engine for a while in some of their cars. It's sort of halfway between an inline and a true V, with a small bank angle. It's more of a staggered inline.

Well honestly the VR5 exists solely as a mid-step; it's not really much more compact than the VR6 and not much more economical. Makes decent power but only to a point...
It wasn't a power or room thing (remember, the only cars that got the engine were the same cars that could be had with the normal VR6 anyways). It was a "circumvent displacement tax laws" thing.
The difference between a V5 and VR5, V6 and VR6 is that the latter of each pair have a cylinder head common to both banks of cylinders rather than a separate head for each bank. It's a much narrower V angle than usual V5 and V6 so it does fit in the engine bay of a smallish car a little more easily.

This also gives way to the quite ingenious method of having both camshafts serve each cylinder, allowing a DOHC head 4-valve design without 4 camshafts.
