Anyone Excited about the 3.0 Duramax?
Just curious really. I thought the inline 6 layout would raise a few eyebrows. I expect the power specs to be inline (see what I did there?) with the ED and the Baby Powerstroke... but with it be...

The GM 3.0 is an I-6 (in-line) correct? If so it will run at a much lower RPM than the Ram and Ford V-6 3.0 diesel. This should give it a much higher life span and much better low end TQ. Now it will not have the same mid power band that the V design has but if GM is putting the ten speed in this truck that should help it out in the mid to lower high end power band areas. I would like to compare the Ford and GM trans ratio's in their 3.0 diesel trucks and see what the differences are.

Engine peak power/torque and how high it can rev depends on other things such as bore/stroke ratio and cam profile, not cylinder configuration.
Precisely....
TRUE,,,,,,,BUT... A V motor designs primary advantage is the ability to fit more cubic inches under the hood. The downside is that some of the internals MUST be smaller. Things like crank journals, bearings and rods. Designers typically compensate for this by altering other parameters to let the motor make power at higher rpms, thus lowering some of the stress on these parts. This gives the motor a distinctly different personality that one either prefers or doesn't.
The major downside is that the V motors have a shorter lifespan than do the in line motors.
In short... Compromises must be made. There is no free lunch.
