With all due respect to the hybrid jocks on this list, give me an
efficient and modern turbodiesel every time. 51mpg, that's fine.
But diesels do just as well, and most of the time better.

I understand that the cost of electrical propulsion cost for
cars is now about one quarter of that for gasoline and diesel only
vehicles. And, as batteries are expected to improve, the
difference will be even greater. Toyota is expected to have a
plug-in option next year and li-ion batteries will increase the
range. I recently got 51.3 mpg on a recent tank of regular
gasoline (473 miles). Also, electricity can be generated from
many different energy sources.

Regarding your last paragraph, Stan, we mustn't forget that
plugging in and charging doesn't come free. You need to add
that component of your electricity bill to your total cost.
And, from an environmental point of view, we must remember
that most of the electricity in the U.S. is generated using
fossil fuels (particularly coal). Canada is, of course, much
better placed in that respect, in that most of their
electricity is produced by hydroelectric power stations
(which, although they don't pollute, do create their own
fairly serious environmental problems).

"*/Hybrids and diesels save, but math can be tricky/*"
in the June 20 issue of The Washington Times explains
various elements to be considered in evaluating auto
purchases; however, they are not easy to use.
Consider standardizing on some basic numbers. For
example, use 10,000 km and 20,000 km (6200 miles and
12,400 miles respectively) driven per year. Then use the
price of $4.00/gallon for gasoline and $4.50 for diesel
fuel to drive those distances. These round numbers
simplify the math and will help people to understand the
differences in savings quicker.
The keys are total distance driven, fuel used and the
cost of fuel. Although miles per gallon or km/L has
increased for new diesel fuel vehicles, it doesn't tell
the full story about the additional cost compared with
gasoline hybrids.
Hybrids with electric drive provide added torque and
better fuel economy than new diesel powered vehicles. And
with an electric plug-in option, hybrids will have even
better fuel economy compared with diesel only vehicles.
