Toyota Motor Engineering & Manufacturing

Toyota Motor Engineering & Manufacturing (often abbreviated TEMA) is the North American engineering, manufacturing and research arm of Toyota Motor Corporation. It is not a standalone consumer brand but an operating unit within the Toyota Group: it engineers, toolbars and builds Toyota and Lexus vehicles for the North American market and coordinates the company's plants, engineering centers and supplier network across the United States, Canada and Mexico. The unit sits at the center of Toyota's North American industrial footprint. Its responsibilities span vehicle engineering and design adaptation for local tastes, production engineering, quality assurance, powertrain and component manufacturing, and the operation of assembly plants that produce models such as the Camry, Corolla, RAV4, Tacoma, Tundra, Sienna and various Lexus vehicles. TEMA also works closely with Toyota's North American research and development operations and with Toyota Motor North America, the regional holding and sales organization headquartered in Plano, Texas. As part of Toyota, TEMA inherits the parent's positioning around quality, durability, reliability, lean manufacturing (the Toyota Production System) and gradual electrification. Its output feeds directly into Toyota and Lexus dealer networks in the region, and its plants are frequently cited in Toyota's announcements about local investment, jobs and future electrified vehicle production. Because TEMA is an internal operating entity rather than a marketed product brand, public information about it is largely corporate: plant locations, production models, investment commitments and organizational changes. It does not have its own consumer-facing website or retail identity separate from Toyota and Lexus.

Toyota's North American manufacturing history began in the 1980s, when the company responded to trade pressure and growing U.S. demand by establishing local production. Early joint ventures with General Motors (NUMMI in California) and subsequent wholly owned plants in Kentucky, Indiana, Texas, Mississippi, Canada and Mexico gradually made North America one of Toyota's largest manufacturing regions outside Japan. Toyota Motor Engineering & Manufacturing North America (TEMA) was created to consolidate engineering and manufacturing coordination for these operations. Over time it took on vehicle engineering, production engineering, quality and supplier development responsibilities, working alongside Toyota's North American R&D and sales organizations. The 2014-2017 period saw Toyota consolidate its North American headquarters functions in Plano, Texas, and reorganize regional entities to speed decision-making. TEMA's plants have produced many of Toyota's highest-volume North American models, including the Camry, Corolla, RAV4, Tacoma, Tundra and Sienna, as well as Lexus vehicles. The unit has also been central to Toyota's announcements of multi-billion-dollar investments in U.S. manufacturing, including preparations for electrified and battery-electric vehicle production. As an internal operating unit, TEMA does not publish a separate corporate history; its story is part of Toyota Motor Corporation's broader North American expansion.

Internal engineering and manufacturing backbone for Toyota and Lexus in North America, built on the Toyota Production System and a quality/reliability reputation.
