And yeah, also going from what Sam is saying about economy - don't think you'll see anything like the economy on road, it's not direct drive!
I expect an XUD9 will actually be fairly uneconomical because at high RPMs they do drink, especially under load...
Imagine that you'll be spinning the engine at 3200rpm all day, but rather than just cruising down the motorway, it's under FULL load at those sorts of RPMs, making boost, moving the water... Imagine that you're under FULL load, going up a hill, at 3200rpm, full torque, they're not that efficient then...
