The Supplier Park plant manufactures Jeep Wranglers and only needs 13.57 labor hours per vehicle. However, not all credit can go to Chrysler because the plant is actually micromanaged by a number of different firms. Kuka Group is used to manage the body shop, while Magna Steyr manages the paint shop and Hyundai Mobis looks over the chassis assemblies.
The next-closest assembly plant was General Motors' Oshawa No. 1 plant in Ontario, Canada. The plant used 15.18 labor hours per vehicle to build Chevrolet Impala sedans.
Chrysler showed the biggest improvement of all carmakers, cutting its total manufacturing labor hours per vehicle by 7.7% to 30.37 on average, the same number recorded by Toyota. However, Toyota's number did slip compared with last year’s result. It needed 2.5% more hours to produce a vehicle this year than it did last year.
Ford improved its total manufacturing productivity by 3.7% to 33.88 labor hours per vehicle, while GM's total improved 0.2% to 32.29 hours.
