does it look ok in grass after import with r.in.arc?

Oh, it's SRTM data.

I suggest you use the r.in.srtm module to import .hgt files directly
instead of messing with old ArcInfo formats from 20 years ago.
see the help page.

$ gdal_translate -of USGSDEM S46E166.hgt S46E166.dem

works fine for me. the geotiff download option from the URL you gave
probably works fine too as input for gdal_translate. gdal loves geotiffs.
