Band 7+: The line graph compares the time spent on producing one vehicle by four car manufacturers based in the USA- namely Nissan, Dalmler Chrysler (DC), General Motors (GM), and Ford- from 1998 to 2002. Units are measured in hours per vehicle.

The line chart illustrates the amount of time that four US-based car manufacturers needed to make a vehicle from 1998 to 2002.

From an overall perspective, the amount of time that Ford spent making a vehicle exhibited an upward trend, while the other US-based car producers experienced a downward trend. Additionally, the figure for DC was the highest in the final year.

The amount of time that Nissan and GM needed to make a vehicle started at 37 hours and 32 hours, respectively. Following this, the figure for Nissan experienced a gradual decrease throughout the period and ended with 25 hours in 2002. Similarly, the figure for GM plummeted to 24 hours in 2000 and continued to decline gradually to about 21 hours in 2002.

At the same time, the amount of time that DC began at 34 hours in 1998. Then, it witnessed a slight drop to 32 hours in 1999, before staying at the same level in the next three years. Finally, 29 hours was the amount of time that DC needed to produce a vehicle in the final year of the period. In contrast, the figure for Ford started at 25 hours in 1998, followed by a gradual increase to 27 hours in 2001 before experiencing a slight decrease and ending at about 26 hours in 2002.
