What does the TNGA architecture mean?

TNGA (Toyota New Global Architecture) is a modular production platform and concept developed by Toyota to address the intense competition in the automotive market, replacing the outdated CE production system. The TNGA architecture represents a completely new approach and methodology to car manufacturing, focusing on how to rationally allocate resources within existing frameworks to achieve greater precision in investment. Toyota vehicles manufactured using the TNGA architecture include the Corolla, Levin, Avalon, Camry, Highlander, Wildlander, and RAV4. Among these, the Avalon is a mid-size car, classified as a B-segment vehicle under Toyota. In terms of body dimensions, the Avalon measures 4975mm in length, 1850mm in width, and 1450mm in height, with a wheelbase of 2870mm.
As a Toyota Camry owner, the TNGA architecture is Toyota's new-generation vehicle platform. Simply put, it standardizes the design of core components like chassis and engines across different models, making production lines more flexible and reducing manufacturing costs, which benefits consumers with more affordable cars. In daily driving, I feel much more stable handling with a lower center of gravity that prevents drifting during turns, and comfort has improved significantly. The interior design is also more user-friendly. I remember the salesperson mentioning when I changed cars two years ago that TNGA allows SUVs like the RAV4 to achieve sedan-like driving dynamics—not just performance optimization but also enhanced safety, such as rigid body designs that reduce accident risks. Actually, many brands adopt this platform concept, but Toyota was relatively early, starting promotion in 2016. Now even the latest Prius models use it, and overall, it feels very hassle-free.
As an automotive enthusiast, I consider TNGA architecture to be a revolutionary change for Toyota. It standardizes the manufacturing foundation for vehicle models, allowing components like chassis, suspension, and powertrains to be shared across platforms. This significantly improves production efficiency, reduces R&D time, and enables automakers to launch new models faster. For instance, a family sedan like the Corolla can now share parts with Lexus hybrid models, offering greater design flexibility and more precise driving dynamics—enhanced cornering grip and more direct steering feedback. Last year, I test-drove a hybrid version with optimized battery placement, delivering smoother acceleration and approximately 10% better fuel efficiency. Even better, TNGA contributes to safety upgrades, as its standardized body structure helps achieve higher crash-test ratings. This platform philosophy is transforming the industry and propelling Toyota toward an electrified future.
