The VW diesel Rabbit was able to approach 50 Mpg a number of years ago...

Yep, I think it was the smell.  Diesel is also easier to refine.

One of the problems in the USA is that our diesel fuel has a lot of
sulfur, which makes for stinky polluting exhauts gases. If and when we
can get low sulfur diesel fuel, the situation could then improve.

52 City - my NHW11 Prius
50 Highway - typical diesel specs

Atkinson cycle means 1:8 compression stroke and 1:13 expansion with
attendant improvement in thermal dynamic efficiency. Then the hybrid
transmission and control laws allows avoidance of inefficient energy
ranges.

Because the US uses a dirty blend of diesel fuel. That is scheduled to
change in a year or 2 with a mandate for clean diesel fuel.

Ultra-low-sulfur (<= 15 ppm) Diesel fuel becomes mandatory for retail
sale in the US on 1 Oct 2006.  It was to be 1 July, but the Bush
Administration, god bless 'em, decided that the poor old oil bidnis
needed some more help.
