A line graph delineates the average time to produce a vehicle by four US car manufacturers such as General Motors, Ford, Toyota, and Honda from 1998 to 2005.
Overall, it is readily apparent that General Motors and Ford spent the most hours per vehicle among all car manufacturers in the given period, while Toyota and Honda exhibited a similar trend.
In 1998, General Motors spent nearly 32 hours to produce a car and witnessed an incredible downward trend to approximately 25 hours per car by 2002; afterwards, General Motors continued its decline in hours per vehicle and achieved roughly 22 hours by the end of the period. Conversely, Ford exhibited growth in hours to produce a car at the beginning of the period, peaking at nearly 31 hours in 2001. However, Ford demonstrated a decrease to slightly fewer than 22 hours in 2005.
In 1998, both Toyota and Honda started with roughly 22 hours per vehicle. Occasionally, in 1999, Honda decreased production time per vehicle to nearly 20 hours, but both firms met again in 2002 at around 24 hours per car manufactured. By the end of the period, Honda and Toyota witnessed about 20 hours per car manufactured.
