Wilmington's Automotive Heritage
For decades, Wilmington was home to General Motors' Boxwood Road assembly plant, which produced vehicles for more than seventy years before closing in 2009. Nearby, Chrysler's Newark assembly plant built cars until 2008; the site is now the University of Delaware's Science, Technology and Advanced Research Campus. These plants shaped generations of local families and the region's manufacturing culture.
Today, the automotive industry in Greater Wilmington looks different. The region supplies advanced materials, coatings, refrigerants, and components to automakers worldwide, while authorized dealer groups bring the products of major manufacturers to local drivers. Here are ten companies central to the automotive landscape around Wilmington.

Materials innovation from local chemical and electronics companies influences how vehicles are built, painted, cooled, and powered. The former Boxwood plant site has been redeveloped into a large logistics facility, reflecting broader economic shifts toward e-commerce and distribution.
Industry Trends
Electrification is the dominant trend. Automakers need advanced battery materials, thermal management solutions, and electronic components, creating opportunities for Delaware's materials companies. Dealerships are investing in EV charging, technician training, and digital retail experiences. Sustainability goals are also pushing manufacturers to adopt lower-emission coatings and refrigerants.

For buyers, choose dealerships with strong service departments, transparent pricing, and certified technicians. For manufacturers and suppliers, Wilmington-area companies offer research partnerships and specialty materials that support innovation.
Frequently Asked Questions
Are any cars built in Wilmington today?
No full vehicle assembly plants currently operate in Wilmington. The region instead contributes materials, coatings, refrigerants, electronic materials, and components used by automakers worldwide.
What happened to the former GM Boxwood plant?
After General Motors closed the plant in 2009, the site was sold and eventually redeveloped into a large e-commerce fulfillment center, bringing new jobs to the area in logistics rather than manufacturing.
Does buying a car in Delaware save money?
Delaware has no general sales tax, but it charges a document fee when a vehicle is titled. Buyers who live in other states must usually pay tax where they register the vehicle, so savings depend on residency.
Are electric vehicle incentives available in Delaware?
Delaware has offered state rebates for eligible electric vehicles and charging equipment through programs administered by the Department of Natural Resources and Environmental Control. Funding and eligibility change periodically, so confirm current details with a dealer before purchase.
How do I choose a reliable service center?
Look for manufacturer-certified technicians, transparent estimates, strong reviews, and convenient scheduling. Dealer service departments have brand-specific diagnostic equipment, which is especially useful for newer vehicles with complex electronics.
What automotive careers are growing in the region?
Demand is rising for EV-trained technicians, materials scientists working on lighter and more durable components, and engineers specializing in battery and thermal management systems. Delaware Technical Community College offers automotive programs that help prepare local students for these roles.
