Why? Whats so good about a V6?

But the 2005 Falcon will more than likely get a 3.8L V6 DOHC.

I recall reading at the launch of the AU that its 4.0 litre 'Intech' six had the same "cylinder bore spacings" of every Falcon six dating back to the 1960 XK. When I tried to make sense of that, I figured the AU is basically a stroked version of that with various evolutionary bits (like the XE's alloy head, XF's MPEFi, EA's SOHC, etc) added over time.

So to answer the question, the AU is an old fashioned car that heavily dates back to a time when inline six cylinder engines were the norm for every car maker. There is another company which refuses to make V6 engines for its products because of the apparent advantages of inline engines - and that's BMW.

Would a straight 8 be more powerful than a v8??? ....thats if there was a straight 8????

Who knows, but what sorta car would u put a motor that long in. I remember readen this old book on cars and there was one with a straight 8. The bonnet was half the lenght of the car

A straight 8 would produce more torque. Trouble is, it would take up so much damn space and weigh so much that it would have few practical advantages over a V8 - and V8's aren't exactly low on torque anyway.

An interesting fact: the 4.0 six weighs only a few kilos less than the cast iron 5.0 V8.

There about 30Kg difference between the 5.0L and 4.0L, alloy heads on a 5.0L saves around 25Kg apparently.

alloys would obviously have other advantages tho....

Well I was quoting the differences between the weight of the EB II XR6 and XR8 - something like 7 kilos. Obviously the XR6 is weighed down by other factors. Still, there isn't much in it.

Whats so good about a v6- easy any veichle, be it car boat or aeroplane handles better when light at the ends a v6 keeps the weight as far back as possible ie behind front wheels therefore will always ultimately handle and ride better this is basic phisics and it also is more space efficient of course.
