This notice is to all who use the MARC 1 Software.

Modules X1, X2 and X4 programs were corrected.
X1, X2 and X4 DID NOT USE secondary impact energies in calculating after-impact speeds. Additionally, in X4 the CRUSH ENERGY of Vehicle 1 was calculated incorrectly. Module X3 was not affected.

Please, download the corrected MARC 1 form this website by clicking on MARC 1 - 2005 and follow instructions.

Thanks,
