At full speed the mileage would drop quite a bit and
approach that of a gas engine--I'll guess 70-75 mpg?

Still it would go 5 1/3 times as far as my pickup truck.

Diesels have a nice amount of torque. They are fast
off the line at a stop light. I used to pull a snow mobile
trailer with my Rabbit diesel. I'll bet a little smart-car
could pull a trailer--which would be a good thing as
tail-gate'r would make me real nervous in a car that
is so obviously vulnerable to a rear end collision.

Damn, at full speed you could drive six hours on a gallon.

I'd buy a diesel version if it was available in the US.
95mpg is fabulous.
