Automotive Manufacturing Statistics 2026

Industry overview

US motor vehicle and parts manufacturing combined generates revenue near $500 billion annually. The Bureau of Economic Analysis tracks the transportation equipment sector, which includes autos, aerospace, ships, and railroad equipment, at total shipments above $1.1 trillion. Motor vehicles, parts, and bodies represent roughly 60% of that transportation equipment total.

Assembly capacity concentrates among the Detroit Three (Ford, General Motors, Stellantis North America), Japanese transplants (Toyota, Honda, Nissan, Subaru, Mazda), Korean transplants (Hyundai, Kia), German transplants (BMW, Mercedes-Benz, Volkswagen), and a growing EV-pure-play roster (Tesla, Rivian, Lucid).

Employment

Direct automotive manufacturing employment splits roughly 30/70 between vehicle assembly (NAICS 3361) and parts manufacturing (NAICS 3363). Assembly plants pay top of the manufacturing wage scale, with skilled UAW positions and senior technical roles often clearing $90,000 to $130,000 with overtime. Parts manufacturing wages run lower, with median compensation between $48,000 and $72,000 depending on role and region.

Top states by automotive employment

Auto manufacturing remains concentrated in the traditional Midwestern automotive corridor (Michigan, Ohio, Indiana, Illinois, Wisconsin) and the Southern automotive corridor (Tennessee, Alabama, Kentucky, South Carolina, Georgia). Transplant assembly has driven the South's share upward since the 1990s.

EV transition

The shift to electric vehicles reshaped US manufacturing investment more aggressively than any change since the Japanese transplant wave of the 1980s. Tesla led volume EV production through most of the early 2020s, with Ford, GM, Stellantis, Hyundai, Kia, and Rivian scaling rapidly. Battery cell manufacturing has drawn the largest single tranche of new factory investment, much of it in Georgia, Kentucky, Tennessee, Michigan, and Indiana under joint ventures between automakers and Asian battery makers.

Supplier base

The US motor vehicle parts supply base is enormous and fragmented. Original Equipment Suppliers Association estimates list 2,500-plus tier-1 and tier-2 US suppliers. Tier-3 and tier-4 (specialty processors, raw material converters, fastener and small-component shops) push the count much higher. Most parts shops sell to multiple automakers, though tier-1s often retain dedicated programs per OEM.

The EV transition has both threatened legacy parts categories (engine, transmission, exhaust, fuel system specialists) and created new ones (battery cell, pack assembly, e-axle, power electronics, thermal management). Many internal-combustion-era suppliers are either pivoting to EV components, diversifying outside auto, or consolidating.

What this means for auto suppliers in 2026

Three forces define the picture. First, OEM consolidation of supplier lists has accelerated. Tier-1s and OEMs prefer fewer, deeper relationships, which favors larger or highly differentiated specialty shops. Second, the EV transition creates winners and losers along clear technology lines, and shops that publish their EV-relevant capabilities (battery enclosure work, power electronics cooling, e-motor stator assembly) capture sourcing-engineer attention faster. Third, AI-driven sourcing research is becoming a real factor at the procurement engineer level. Shops with structured capability content win shortlist consideration.
