March 2026 Industry Roundup
Indiana’s automotive manufacturing engine is accelerating again—and this time, the momentum is being driven by electrification, advanced vehicle platforms, and major reinvestment in U.S. production.
In late March 2026, Toyota announced a $1 billion investment across its Kentucky and Indiana manufacturing operations, with $200 million dedicated to expanding production capacity at its Princeton, Indiana plant to support the Grand Highlander SUV program

For Indiana manufacturers, this is more than a headline—it’s a signal that new programs, tighter timelines, and higher technical expectations are arriving quickly.
What’s Changing on the Plant Floor
Automotive manufacturing in Indiana is no longer just about volume. It’s about adaptability and execution.
OEM and Tier suppliers are navigating:
- Retooling legacy equipment instead of full replacement
- Increased platform complexity tied to EVs and hybrid architectures
- Shorter launch windows with fewer opportunities for late changes
- Growing pressure on procurement teams to secure reliable, flexible engineering support
According to the Indiana Economic Development Corporation, Indiana remains one of the most manufacturing‑intensive states in the U.S., with automotive production forming a critical backbone of the state’s economy

In this environment, early engineering decisions directly affect cost, uptime, and launch risk.
Why These Investments Matter Locally
Toyota’s continued reinvestment reinforces Indiana’s position as a long‑term automotive manufacturing hub, not just for assembly, but for advanced production and supply‑chain support.
The Princeton facility alone employs thousands of Hoosiers and anchors a large regional supplier network. Expansion efforts like this typically create downstream demand for:
- Equipment modification and validation
- Tooling and fixture updates
- Engineering documentation and change control
- On‑site technical support during ramp‑up phases
As the Evansville Regional Economic Partnership notes, reinvestment at this scale sends positive ripple effects throughout Indiana’s manufacturing economy

Where Jarrett Engineering Fits In
This is exactly the environment where Jarrett Engineering does its best work.
For more than 60 years, we’ve supported Indiana automotive manufacturers with production‑ready engineering, including:
- Machine, tooling, and gage design
- Equipment modifications and line upgrades
- Validation support before fabrication and commissioning
- Flexible, on‑demand engineering resources during peak workload periods
We’re often brought in when:
- Internal teams are stretched thin during launches or retooling
- Equipment must be modified without disrupting production
- Engineering decisions carry real financial and downtime risk
- Manufacturers need vendor‑independent technical judgment
Our focus is practical: form, fit, and function, applied where decisions are still inexpensive to change.
Why This Matters Now
As Indiana’s automotive sector invests heavily in new platforms and technologies, the cost of getting engineering wrong continues to rise.
The most resilient manufacturers are:
- Engaging engineering support earlier
- Stress testing designs before fabrication
- Reducing commissioning and field‑service risk
- Treating engineering as a strategic advantage—not a last-minute fix
That mindset shortens launch timelines and protects capital investment.
Built for Indiana Manufacturing
Jarrett Engineering is proud to be an Indiana‑based engineering firm supporting Indiana manufacturers.
We work alongside engineering, maintenance, and procurement teams who need solutions that perform on the plant floor—not just in theory.
Indiana’s automotive industry is evolving quickly. The companies that stay competitive will be the ones that pair smart investment with disciplined engineering.
That’s where we come in.
