MaxxPower APU

The only info on this unit is what has been mentioned about it in the press release for the Fleetrite APU.

Navistar also will offer a factory-installed APU called MaxxPower™ as an option on new International® Class 8 trucks beginning later this year.

I just found this on Reuters.

MaxxPower APU – Operating at 4.2 kW, the MaxxPower APU equates
to best-in-class fuel consumption of .18 gallons per hour. It
features EPA Tier IV certification and is in the process of
acquiring CARB ‘08 emissions compliance. Several states
currently offer incentives for trucks with idle reduction
systems. Production is slated for later this year.
