The Pierre Auger Collaboration has decided to include detector enhancements in order to have unitary detection efficiencies down to 10^17 eV in cosmic rays detection. These enhancements consist in high elevation telescopes and an infill area with both surface detectors and underground muon counters thus allowing a detailed study of the spectrum region where the cosmic rays sources are assumed to change from galactic to extragalactic origins.
