Then, the average vehicle production time achieved the lowest peak, approximately 24 in 2002. In contrast, Daimler Chrysle had a gradual decline during this period. In 1998, around 34 hours are spended to make vehicles, and approximately 32 in 1999. There were not any changes between 1999 and 2001, but then the figure dropped from 32 in 1999 to about 29 in 2002.
