Because it's not an environment variable, but only a shell variable :-)
Which makes sense, as otherwise all the shells invoked by bash could be
too easily mistaken for bash shells *shudder*

I can obtain, on my Debian box:

 $ env -i /bin/sh -c 'env'
 PWD=/devel/stefano/src/am/branches/trunks
 SHLVL=1
 _=/usr/bin/env

 $ env -i /bin/sh -c 'echo "$BASH_VERSION"'
 4.1.5(1)-release

all as expected IMO.  I guess the sae would happen on every sane system
out there.
