Automobile Engine & Parts Manufacturing in the US Industry Data and Analysis
Automobile engine and parts manufacturers produce gasoline and diesel-powered engines and parts. The industry primarily consists of vertically integrated automobile manufacturers and large companies that provide engines, filling supplementary contracts for automakers and aftermarkets. Manufacturers are highly globalized, benefiting from international supply chains and global demand. Even so, volatile economic conditions, skyrocketing input costs, worker strikes and massive pressure from both foreign manufacturing powers and electric vehicles have slammed revenue and profit growth. However, falling rates, rebounding economic conditions and easing supply chains have created positive tailwinds, though the threat and implementation of tariffs have sent the industry into contraction in 2025. Overall, revenue for automobile engine and parts manufacturers has expanded at an expected CAGR of 0.8% to $42.2 billion through the current period, despite stagnating in 2026, where profit settled at 2.9% of revenue.
