inline engines are better balanced and since there are more cilinders to the crankshaft...by that i mean each cylinder has its own main rather than sharing a main like a v engine which has 2 pistons per main..there is a lot more strength....definitely a lot more torque...engines are cheaper to produce but thats not the real reason they are being used...thay have more use for heavy machines and can handel it better than any V engine...a deisel inline six would sure be something though..deisels are awesome engines which would be the only reason they are used instead of inlines.
