Even shaft seals are getting ecomodded...

Attributing increasingly stringent US fuel economy (CAFE) rules as the motivation for the development...

Quote:
...one of the largest suppliers of seals for rotating shafts, says it has developed a new design that reduces rotating friction by as much as 75%. If incorporated on all the seals on a typical OEM powertrain—including the engine, transmission, axle and bearing—the new design could improve fuel efficiency by about 2%, according to the supplier.

The seal design also apparently:
  • removes the need for a steel pressure ring
  • reduces heat build up, extending life
  • is being used in one un-named new engine

That shaft seal is a "bad mother- (shut your mouth!)"...

In all seriousness, it's encouraging to see manufacturers look at more areas of engineering to improve FE. I wonder when we'll find out who is using the new design (and if it's in the NA market)...

Plus, I can't resist bad 70's humor.
