The M38--or Willys Model MC--was the first Jeep in a new generation of military vehicles. It was built from September 1950 to July 1952. By the time the MC was developed, the military was looking to standardize everything possible. A new line of small parts, such as generators, starters, gauges, switches, and so on, were developed to be used in every military tactical rig. The M38 was the first military Jeep to contain these improvements. The M38 was considered a disappointment in terms of performance. The Army’s new requirements, including a higher weight capacity, added many pounds to the vehicle, and the old Willys 60hp Go-Devil had run out of go. The push to develop a more powerful engine led to the M38A1 and CJ-5 vehicles.
