Band 6+: The graph below shows the amount of time taken to produce a vehicle by four US-based car manufacturers in the years 1998 to 2002. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The given chart demonstrates how many hours spent manufacturing a vehicle by different US-based car manufacturers from 1998 to 2002.

Overall, the production time of Nissan, General Motors (GM) and Daimier Chrysier (DC) reduced while the number of hours spent producing Ford generally increased in the given time surveyed.

In 1998, the number of hours spent producing Nissan was the highest, at 37 hours per vehicle. Followed closely by the number of that for making a DC (34 hours). 32 hours and 24 hours were the total amount of time to manufacture Gm and Ford, respectively.

Over the subsequent years, there were significant variations in the vehicle production time. In 2000, the manufacturing time of Nissan declined remarkably to only 24 hours before experiencing a further drop to below 22 hours. A similar pattern was witness in the DC production hours, dropping to 32 hours in 1999 then remaining stable in the following 2 years. However, at the end of the period, there was a reduce in production time, it only takes below 30 hours to produce a DC. The manufacturing time of GM showed a more stabilizing pattern, with a decline in production time from 32 hours to only 24 hours. In contrast, it took longer to produce a Ford than other types of car in 2002 (26 hours compared to 24 hours at the beginning of the period).
