Mexa-Clark double articulated 8x8 was one of the three versions of Mexa or Vexa vehicles (one 8x8 with double articulation, one articulated 10x10 and an articulated tracked) witch were tested from 1967 to 1972 in soft soils. Mass 7 T for the 3 models. WES, Waterways Experiment Station, Vicksburg, where these vehicles stay now in open air, was the supervisor of the project, intended to compare means of locomotion and verify calculations.

Mexa-Clark (or Vexa) articulated 10 x10. The 3 versions were fitted with an inching system wich curiously revealed unusefull in very soft soils, while they performed well. However, mass of 7 tons to carry 3 tons only was considered as poor. Pict of SAE Paper, Society of Automotive Engineers, N° 730037 on MEXA, Jan 1973.
