  We use field theoretic renormalization group methods to study the critical
behavior of a recently proposed Langevin equation for driven lattice gases
under infinitely fast drive.
  We perform an expansion around the upper critical dimension, d_c=4, and
obtain the critical exponents to one loop order. The main features of the two
loop calculation are then outlined. The renormalized theory is shown to exhibit
a behavior different from the standard field theory for the DLG, i.e. it is not
mean field like.
