How do you like your German car?

I don't think that's true. The V6 is 3.0 and the V8 is 5.0 so the cylinder size is bigger on the V8. This implies it's a different block even if it shares some design commonality.
With Audi they use a 2.0 I4, 3.0 V6 and a 4.0 V8 so in their case what you say is correct. BMW has the same commonality between its 2.0 4 cylinder and. 3.0 6 cylinder.

The cylinder size is different yes, but the AJ126 is externally the same dimensions as the AJ133.
The block is the same on the outside but it's cast with different internal layout.
The maximum number of parts possible is shared between the two engines. e.g. the sump is the same, the front timing cover the same, and so on.
The design is such that wherever the V6 fits, so does the V8 & vice-versa. Even the exhaust pipes with the catalysts are the same on the two engines (from the exhaust manifold back).
There is not a single shared part with Ford engines. Nothing at all.

I found the link that says the AJ126 (V6) is essentially the same block with 2 less cylinders than the AJ133 (V8). The AJ133 has bigger bore and longer stroke.

Yep essentially the same block on the outside, but internally it's cast with six bores instead of 8. That's how most of the bolt on parts can be shared between the two. Certainly helps to keep costs down!

Both Ford and Jaguar are committed to high power density blocks so I think we'll see some amazing stuff coming out of both in the next few years (the 600hp Ford GT is an example!)

I guess I have a different view. I don't think the F-Type V6 engine is particularly distinctive for its vintage. A V6 plant is capable of a lot more.

Ford is moving in the direction of twin-turbos, and will get a lot more from their design. I don't know as much about what JLR is doing with the new Ingenium line.
