The automotive industry faces relatively low barriers to entry but moderate threats from substitutes. Supplier power is increasing from traditionally low levels as suppliers grow larger. Buyer power is moderate to high as customers have many options and low switching costs. Competition among existing players is intense, despite market concentration, as emerging markets grow and customers demand more options. OEMs are addressing regulatory requirements by shifting product mixes, using more modular platforms, and increasing electronic content in vehicles. Retail activities are also changing as customers do more research and want more involvement in purchasing decisions.
