Ford's new V-6 diesel

No mechanical engineer here but I think there is gobs more torque in straight sixes than "v"s. Cdean should be lurking nearby and he can explain.
This is a guess on the GM 6's. Are the pistons, rods, valve sizes etc. shared with the current ls1 based motors? If they are it might be easier to cast a straight 6 block and use some common internals then to do a V block. Ford sort of does this with their 2 current V8's and the V10.

BTW, there was a slight inaccuracy in the engine dynamics discussions earlier: the 60deg V6 is better than the 90deg V6 but still has a slight secondary dynamic imbalance. The I6 OTOH enjoys perfect secondary balance.
That's not to say V6s are bad engine configurations. As mentioned, the 60deg V6 is generally more compact than an equivalent displacement I6. The 90deg V6 has the cost advantage of being able to be produced on the same line and share parts with the 90deg V8. Both are still far smoother than the inline-4 which has an inherent imbalance due to the rod angle difference between the upstroke and downstroke cylinder pairs. The result of that is a 2X RPM vibration that everybody knows as the 4 banger buzziness.
