Looks like they are calling it the new HPFP CPN5 series and it's got a very, very long commercial application life rating... that's gonna be expensive....
What bothers me is the CP4 appear here to stay for a while.
There is no major redesign beyond what they already did.
Look at the size of the medium-heavy duty version.
I wonder if it is oil lubricated.
The gossip in the trade is the piezo injectors are too expensive and the next move will be to go back to HEUI.
Ford may go back to HEUI, VW is more than likely to go to 2nd or 3rd generation Solenoid injectors in lieu of Piezo. When run with 1800 bar pressure and Nox treatment via DEF, so far, the reliablity has been good in 1st generation 2012 and 2013 Passat's, quite low failure rates so far, at least showing up on the internet.
