hyundai boasts that the yf comes with cracked connecting rods found in upper class cars such as the benz SL.
is this all hype ?

I like your explanation too. Its much less wordy than mine!Hmmmm, I had to look that one up:
High strength cracked connecting rods are used that minimize weight and size, while also increasing connecting rod rigidity and long term durability. A "cracked" connecting means that the rod and cap are forged as a complete unit during the manufacturing process, and then cracked apart to create a custom fit between the two matching surfaces. The use of high strength steel contributes to the connecting rod's slender shape and results in a 50 percent increase in fatigue resistance for a long lasting engine.
The design allows for the elimination of connecting rod bolt pins, since the connecting rod bolts can be precision machined to fit the cap to the rod. The end result is a connecting rod that is 13 percent lighter and has a 20 percent smaller cross section, resulting in less rotating mass inside the engine and less space occupied by the connecting rod - a significant component to creating a powerful, efficient and compact engine.
Crap. Ford has been using that method since the early '90s, and it's widely used today. And there's nothing 'fancy' about that; it's just a cheaper way to build connecting rods that happen to be better too, that's all. For those who don't know what that is, picture a one-piece connecting rod. Rather than cutting the large (crankshaft) end in two right at the middle, it's cracked, meaning it can only be put back together one way, which fits perfectly and avoids any kind of side/lateral motion, for better durability. So yes, cracked conrod caps are not interchangeable; each one is unique, and only mates its 'paired' conrod. Hope this helps.
And Ford, and GM and BMW and Mercedes...its just not one manufacturer...so why is hyundai making a big deal out of it ? I'm getting sick of hyundai's attempts to boast gimmicks....it's very misleading.
If I ran a shop or produced a product, I would not hold back on trumpeting a special procedure that was beneficial simply because my competitors chose NOT to publicize it. In fact, shame on them for not talking it up.so why is hyundai making a big deal out of it ? I'm getting sick of hyundai's attempts to boast gimmicks....it's very misleading.
This is a very common practice.If I ran a shop or produced a product, I would not hold back on trumpeting a special procedure that was beneficial simply because my competitors chose NOT to publicize it. In fact, shame on them for not talking it up.
I certainly would not in good conscience claim I was the ONLY one to do something if that were not the case, but I would not be shy about marketing it if I knew it to be something good.
