It is demonstrated that in the relativistic limit where c \to \infty, the fermionic Born-Infeld model reduces to the supersymmetric Chaplygin gas model in one spatial dimension. However, the supersymmetry itself is not preserved.9 pages. Several references have been added, as well as the journal reference numnber and the DOIMathematical Physicstext
