Combined, the two plants give Toyota a maximum capacity to produce 300,000 Tundra units annually or 100,000 units from the Indiana plant and another 200,000 units from the Texas plant. When designing the Texas plant, Toyota arranged for 21 key Tundra suppliers to set up factories on the same site to avoid logistical issues. However, those suppliers are more vulnerable to a market downturn. Toyota also included a $9 million health care facility to serve workers and their dependents. The Tundra has 75% North American parts content. In the second quarter of 2008, Toyota moved all Tundra production to the Texas plant. All Tundra engines and transmissions are built in the United States. As sales fell in 2008, production of the Tundra at San Antonio stopped for three months. Safety The Tundra comes equipped with dual front airbags, front row side torso airbags, and rollover sensing side curtain airbags for both the front and rear rows. Vehicle Stability Control,
