The line graph presents the average number of hours spent producing a vehicle by four US car manufacturers, General Motor (GM), Ford, Toyota, and Honda, over a seven-year period from 1998 to 2005.
Notably, GM and Ford consistently had higher total hours to produce cars Toyota and Honda. Moreover, GM and Ford had opposite trends from 1998 to 2001 before collectively experiencing a downward trend until the end of the given period. Similarly, in the first four years, Toyota and Honda also had reversing figures, which decreased and became quite similar to each other afterward.
According to the graph, in 1998, General Motor had the highest average hours per vehicle (hpv), with 32 hpv, followed by Ford ( 28 hpv). However, the situation changed during the first 4 years, when Ford’s figures sharply rose and surpassed GM’s numbers, which dramatically declined to below 28 hpv, demonstrating a reversing trend. From 2001 onwards, both manufactories witnessed a significant drop to around 24 hpv.
Toyota and Honda had the same starting point; however, similar to GM and Ford, from 1998, these companies also experienced opposite trends. In the first four years, Toyota’s figures fluctuated slightly around 22 hpv, while Honda’s fell to 20 hpv and rose erratically, eventually reaching the same level as Toyota. From 2001 to 2002, the two companies’ figures were the same; despite some differences afterward, both reached a similar end at 20 hpv.
