Toyota is implementing structural innovation across our global carmaking business to make ever-better cars. We are changing the basic architecture of our cars to greatly enhance basic performance and product appeal through Toyota New Global Architecture (TNGA).

TNGA is a program of structural innovation, starting with changing the basic architecture of vehicles. Through TNGA, we are completely remaking the powertrain unit (engine, transmission, HEV unit) and basic frames (chassis). With integrated product development, we anticipate a rapid improvement in the three areas of basic driving performance, namely, moving, turning, and stopping. In doing so, we hope to continue providing cars that our customers cherish.

The idea of the TNGA cycle underlies the improved basic and product performance of Well-built Cars while incorporating smart sharing that considers total optimization and promotes Smart Monozukuri (manufacturing) in collaboration with suppliers and production sites. This initiative has enabled a reduction in development resources and reinvestment of reserves to improve quality and product performance, leading to a timelier delivery of ever-better cars.

The Integrated TNGA Cycle

TNGA and the Company System are the Pillars that Support Making Ever-better Cars

Toyota has adopted a product-based in-house company system to enhance fundamental design in hopes of drawing attention from our customers and improving basic performance to provide an experience that makes drivers want to keep driving. We are also aiming for total optimization by pursuing smart sharing, thereby improving efficiency and reducing costs. These efforts are greatly increasing our potential to create aisha, which in Japanese means "cars beloved by customers." Building on the foundation provided by TNGA, the in-house companies consider market needs and consumer preferences in each region to craft distinctive, appealing cars that customers will love. Under the company system, each in-house company prioritizes development based on the vehicles it feels are needed by society or individual regions. In addition, bringing everything from planning to production within the company allows for faster decision-making.

Pillars that Support Making Ever-better Cars

Starting with the fourth-generation Prius in 2015, TNGA initiatives have gradually expanded and are now applied to over 40 vehicle models, including long-selling models such as the Corolla, Camry, and Yaris. The fifth generation Prius in 2023 has adopted the matured second-generation TNGA platform to achieve innovative styling and driving performance. TNGA will continue evolving to further "make ever-better cars."
