More powerful, yes!
More fuel efficient?!? No way. Once they went direct injection with variable nozzle turbos, they were as efficient as they've been. Esp with the 5 and 6 speed automatics. Now it's all about injecting more fuel to make more power (no way around that) so the injectors are a little less efficient now, esp at lower flow rates.
Add the regeneration and other emissions related strains on fuel economy and it's clear that a 2006 diesel pickup will get significantly better fuel economy than a 2013 diesel pickup. They pollute less at some expense in fuel economy, and a huge expense in purchase price.
