What does Toyota TNGA structure mean?
2 Answers
Toyota TNGA structure refers to Toyota New Global Architecture, which is a modular production platform developed by Toyota to cope with the fierce competition trend in the automotive market, replacing the old CE production system. Toyota models under this architecture include the Avalon, Vellfire, Alphard, and PRIUS. Taking the PRIUS as an example: its body dimensions are 4450mm, 1725mm, and 1510mm respectively, with a wheelbase of 2700mm. The PRIUS features a triangular integrated design, large combination headlights with double-layer high-brightness LED headlights, and combination taillights with reflective LED brake lights, crystal-like turn signals, and prominent reverse lights. The PRIUS is equipped with a hybrid synergy drive system, which improves motor output power by increasing the voltage of the power supply system.
I've spent quite some time studying TNGA, and essentially, it's a new global vehicle platform introduced by Toyota. Simply put, all new cars are built based on this foundational design. In the past, Toyota had too many models, which led to scattered resources. Now, with a unified architecture, they can share chassis and components, such as engines, transmissions, and electronic systems, all modularized. This improves production line efficiency and significantly reduces manufacturing costs. The benefits include much better handling in new cars, a lower center of gravity, stability around corners as if glued to the road, and shorter braking distances. The suspension provides strong support, making rides on bumpy roads less jarring. Safety performance has also been optimized, with more rational impact absorption in collision structures and additional key points for airbag placement. I've driven the TNGA-based RAV4, and the steering feedback is very responsive. Fuel consumption is 10% lower than the previous model, and maintenance is more hassle-free. This integration keeps Toyota competitive globally and allows for the rapid introduction of new hybrid models.
