I just curious the new Paccar MX 12.9 L (510 HP) engine only maid for
Europian market ? I ask the dealer they don't hear nothing from this tipe
of engine, only the 5.9 L engine have information.

I have heard rumors this will be in the US also. All these engines are are rebadged Cummins for now. I do know Paccar is interested in producing their own engine so they are not locked into Cummins or Cat.
