According to the data, average capital expenditure per project has risen significantly due to larger facility scale, front-loaded infrastructure commitments and longer, more utilization-sensitive payback periods. While overall auto capex fluctuates year to year, individual projects now carry greater financial exposure and less margin for error in timing and location decisions.

Employment per project has increased more slowly than capital spending, indicating capital deepening rather than labor substitution. As a result, GLS said, balance-sheet risk is concentrated in a smaller number of high-value investments.

Projects exceeding $1 billion accounted for 18 percent of total automotive capital expenditure in 2015, rising to 43 percent in 2025.

Although smaller projects still make up most counts, their number has declined over the past decade, according to GLS. This shift means investment may appear weaker when measured by volume alone, but delays or ramp-up challenges now carry significantly greater financial consequences.

Automakers are adjusting investment strategies in response to higher costs, tighter capital discipline, geopolitical uncertainty, shifting trade policy and rising competition, particularly from Chinese manufacturers. As a result, companies are prioritizing execution certainty and operational flexibility over rapid capacity expansion, with greater emphasis on reliable site delivery and smoother production ramp-up.

“What has changed is not the importance of cost, but the order of operations. Execution feasibility has become the primary gating criterion, with cost optimization occurring only after delivery certainty is established,” the report said.

Corporate leaders face a new investment discipline that prioritizes selectivity over expansion, according to the report. Strategies now begin with ruling out risk rather than optimizing growth, and site decisions must be based on proven delivery capability instead of projections. Flexibility must be deliberately built through phased infrastructure and staged capital deployment. 

For regions seeking automotive investment, basic readiness is no longer an advantage but a requirement, the report concludes.
