Round Rock and the Rise of Central Texas Automotive Manufacturing
For most of its history, Texas was better known for buying vehicles than building them. That has changed dramatically. Round Rock now sits within one of the fastest-growing automotive and mobility regions in the country, shaped by electric vehicle factories, semiconductor plants that supply automotive chips, and innovative startups focused on electrified powertrains and off-road vehicles. The city's position on Interstate 35, its access to rail and highway freight, and its skilled workforce make it a natural base for suppliers and engineers serving the industry.
This guide highlights ten automotive manufacturers that are building vehicles, powertrains, or critical components in and around Round Rock. Each one contributes to the region's reputation as a center of next-generation mobility.
