IMV architecture for rugged vehicles and the Hilux brand of vehicles for emerging markets, are two favorable factors that Toyota hopes will generate half a million more sales than the old Hilux line. Toyota has spent $1.4 billion on building plants in India, Indonesia, Argentina and S. Africa and other countries to develop the new vehicles with new chassis, engines and other parts made in developing countries. These plants say chief engineer Hoskawa help reduce costs by 20-25% for the Hilux line of rugged vehicles with new chassis. But a port strike in India which makes the manual transmitssions, and a problem at the plant in Indonesia which makes gasoline engines- which are then shipped to plants for assembly in South Africa and Argentina- could cause problems. To cushion against such events Toyota keeps 2 weeks supply of engines and other parts in Thailand.
