Seems like you'd still need a fuel-burning descent system to get down to
a velocity where the airbags could be deployed. Sounds doable though,
just as was done in the Apollo program. But wouldn't the gravity
difference between the moon and Mars be quite a factor?

Moon's about 1/6th of standard G, and Mars is about 1/2 of standard G.
(Earth is one G for reference) The difference between Mars and moon's
gravity may be enough that crash testing wouldn't work right.
