Toyota is supposed to announce a new pickup truck in Chicago soon. I
wonder if it will be a diesel hybrid.
--

The Chicago Auto Show comes to town this weekend, and the 2007 Tundra
will
be introduced on Thursday.

Thanks to problems with consumer diesels by various makers in the 1970's,
diesels have a bad rap in the U.S. There will have to be a general
consumer
re-education before diesels are widely accepted as a viable passenger car
option in the U.S. AFAIK, only German makers offer a passenger car
diesels
for sale in the U.S., even though Japanese makers offer diesel passenger
car
engine elsewhere in the world. My guess is that a consumer diesel hybrid
would be introduced in Europe or Asia before it is introduced in the
U.S.

A diesel hybrid would be good in my mind. I remember the VW diesel,
(not a hybrid), 50 MPG. I also like the trains, LOL. I wonder, if it
would be likely there could be diesel hybrid 18 wheelers?

Let's hope we get them back.

If VW's TDI can get 50 MPG, it seems logical that a hybrid could do even
better.

The challenge to producing a ddiesel hybrid 18 wheeler (tractor-trailer) is
weight. The amount of cargo tractor trailers can carry is often limited by
gross vehicle weight. In other words, the trucks are capable of carrying
more weight than is legal on many roads. The batteries needed to acceptably
power a tractor trailer would probably reduce the vehicle's payload too much
to carry anything but really light loads like feathers or bread.

BTW, I believe that the term "18 wheeler" is going to become one of those
anachronistic terms like "dialing" a phone number or "ring" tone. Single
wide tires are gradually replacing dual tires for improved fuel efficiency
at lower cost so an 18 wheeler will become a 10 wheeler.
