Band 5+: The chart below gives information on the amount of time taken to manufacture a vehicle by four US-based car producers between 1998 and 2002. Provide an overview of the information by identifying and describing the key details, and include comparisons where appropriate.

The line graph illustrates the required time to produce a vehicle by four US car brands from 1998 to 2002.

In general, the amount of manufacturing time at Ford was on an upward trend, whereas other brands had reverted over four years. Although it took Nissan a longer time to make a certain means of transport at first, it eventually surpassed others and became the fastest.

At first, the time of vehicle production at General Motors (GM) was shorter than Ford by about 5 hours. During the first two years, Nissan experienced a significant plunge in around 24 hours; besides that, GM declined to meet Nissan in 1999 and gradually continued for the rest of the time frame. The Nissan car producer had reduced the necessary time to create a vehicle moderately, as well as GM, before slightly declining in the last year. Obviously, the Nissin former had the shortest manufacturing time, compared to other counterparts.

A closer look at the chart reveals that in 1998, Daimler Chrysler recorded 34 hours of production time, nearly 9 hours longer than Ford. In the initial year, the qualified creation time of DC had experienced a marginal decrease, while Ford slowed their process. From then on, the Ford car makers increased their time to approximately 27 hours in forming considerably, even though their opponent was stabilized at 31 hours in 2001. In the final year, the amount of time used for producing a vehicle by DC suddenly declined; on the other hand, Ford was just a few hours lower.
