I measured the actual plates themselves for the 5T thread and came up with the following (with a ruler, not exact... they turn out to be .5mm off):

372mm HPI Savage XL
314mm HPI Savage X

which is a diff of 58mm, or 2.2". :)

Which corresponds with the stated wheelbases on HPI's site (http://www.hpiracing.com/kitinfo/10515/) of

395mm XL
336.5mm X

or a diff of 58.5mm.

HPI also states 590 as the length of the XL not 570.

Wheelbase is extended 1.9" from stock Savage length.
1'' = 25.4mm
1.9'' = 48mm

So it's 12mm longer than a XL.
