I just returned from covering the 2003 Michelin Challenge Bibedum, a competition organized to show the progress being made in cleaning up our cars and trucks.
Besides having a chance to drive a couple modern diesels from Europe including the superb Mercedes E320cdi and a PT Cruiser with a diesel engine in it, I learned something interesting about what's happening at Ford.
Over a year ago Ford was working on an innovative hydraulic hybrid that used compressed hydraulic fluid instead of electricity and batteries to capture regenerative braking energy. They had installed the unit in a big, honking Navigator or Excursion -- I don't recall which, but I do have video of it somewhere in my files. I also drove it and came away very impressed. Ford engineers told me the unit improved the SUV's fuel economy by something like 40% while reducing emissions, etc. It also had stunning acceleration.
So what happen to that promising project?
As I walked through the "Education Center" at Infineon Raceway outside Sonoma, I discovered the answer. Cash-strapped Ford had shelved the program. But that's not the end of the story.
Turns out Eaton Corporation -- which is building the hybrid drives for FedEx's new "green" fleet of delivery vans -- is continuing the research on the system, which would be really useful in heavy vehicles that do a lot of stop and go urban driving like refuge trucks. There next to a full-scale mockup of Eaton's hybrid-drive transmission was a tiny model of the HLA (hydraulic launch assist) system. The model was identical to the black one Ford had shown me over a year ago, but this one was painted blue with "Eaton" written in white letters on the side of one of the cylinders. Could have been the same model for all I know.
It will be interesting to see what else gets the axe at Ford... and DCX and GM as the Rust Belt struggles to remain technologically competitive under a mountain of debt and pension payments.
Meanwhile, Toyota already has more than 20,000 orders for its new Prius that goes on sale October 17th for under $20K. After having driven it in a rally through Sonoma County, it gets my vote for the best new auto technology for 2003. It is a stunner. Detroit has nothing to compare to it.
