The line chart depicts the average hours required by four car manufacturers to produce vehicles at their US factories between 1998 and 2005.
Over the period, the average production time for the four manufacturers generally decreased, despite some fluctuations, with General Motors being the exception.
In 1998, General Motors had the longest production time, with an average of 32 hours per vehicle, which significantly decreased to around 24 hours by 2005.
Ford followed, taking 28 hours to build a vehicle in 1998, before rising to 31 hours in 2001 and then dropping to around 22 hours in 2005.
Honda and Toyota both required 22 hours to build a vehicle in 1998. The following year, Toyota’s production time increased slightly to around 23 hours, while Honda’s moderately decreased to 20 hours. However, by 2001, both had returned to 22 hours. Their production times continued to fluctuate, rising to 24 hours in 2002 before eventually decreasing to 20 hours by 2005.
