How EVs Are Shaking The Car Parts Supplier Industry

Companies that make parts for internal combustion engines are facing a harsh future. Revenues for ICE cars, and fuel and exhaust systems are all expected to decline 44% through 2027. Meanwhile, for electric drivetrains and batteries or fuel cells, revenues are expected to rise 245%, according to a 2023 Deloitte Automotive Supplier Study. While the parts themselves are changing, the pie is also shrinking. An internal combustion powertrain has about 2,000 parts. EV powertrains have about 20, sometimes less. Automakers are also finding ways to more efficiently manufacture parts through methods like giga casting, pioneered by Tesla. There are thousands of parts in cars that come from companies all over the world, a whole branching supply chain of firms each dependent on the success of the others. Many of those companies are small, family owned firms, but even the large, publicly traded suppliers such as Bosch, Denso, Magna and ZF could be in trouble. The question is, will EVs kill the thousands of auto suppliers
