I was wondering what, if any real "advancements" in driveline efficiency have been made in say, the last 10-15 years. XJ's have a reputation for being not so fuel efficient and that a lot of that has to do with being 4wd, solid front/rear, etc. and I was wondering if any of the new driveline designs could be used in the XJ application to maybe squeeze a little more power to the wheel and/or get a little bit more MPG's.
Driveshafts, u-joints, axles, transfer cases, tranny's, etc. which of these are more or less efficient (leading to the least amount of drivetrain loss) than other models, or types? Assuming you're on stock rubber (just to take tires out of the equation because I think we all know that a set of 38" SS's are gunna lead to more rolling resistance than a set of street tires).
Doesn't seem like this subject has been addressed much (possibly for good reason) but I'm curious.
