Toyota New Global Architecture


The Toyota New Global Architecture is a modular automobile platform that underpins various Toyota and Lexus models, starting with the fourth-generation Prius in late 2015. TNGA platforms accommodate different vehicle sizes and also front-, rear-, and all-wheel drive configurations.
The platforms were developed as part of a company-wide effort to simplify the vehicles being produced by Toyota. Before the introduction of the TNGA, Toyota was building roughly 100 different platform variants., the five TNGA platforms underpin more than 50% of Toyota vehicles sold worldwide and is expected to underpin about 80% by 2023.
Each platform is based on a standardized seat height that allows for sharing of key interior components such as steering systems, shifters, pedals, seat frames and airbags. These components are often less visible, allowing for cars that share platforms to have unique interiors. Compared to Toyota's older platforms, TNGA costs 20 percent less to produce while offering increased chassis stiffness, lower centers of gravity for better handling and lower hood cowls for better forward visibility.
The TNGA platform was developed alongside the Dynamic Force engine, which similarly is replacing more than 800 engine variants with a much simpler lineup of 17 versions of nine engines. Toyota is also simplifying its lineup of transmissions, hybrid systems, and all-wheel drive systems.

TNGA-B (GA-B)

The TNGA-B platform underpins unibody vehicles in the A-segment or city car, B-segment or subcompact car, subcompact crossover SUV, and mini MPV categories. Developed by the internal "Toyota Compact Car Company", the platform is offered in both front-wheel drive and all-wheel drive variants and is paired with a transverse engine. The platform also supports a wheelbase length of, while only supporting three-cylinder engines. The TNGA-B replaces the older B platform.

e-TNGA is a modular platform dedicated to battery electric vehicles, which was announced in October 2019. Internally known as the 40PL platform, the platform will enable offering various type and size of vehicles, different battery capacity and with front-wheel drive, rear-wheel drive or dual motor all-wheel drive. This vehicle architecture is partitioned into five modules. These are the front module, center module, rear module, battery and motor. Up to three versions of each module are in development, including three capacities for the lithium-ion battery. The first e-TNGA-based model is the bZ4X crossover, which was presented for the first time in April 2021. Other vehicles planned by 2025 include a medium SUV, a medium minivan, a medium sedan, and a large SUV. For Subaru-badged models, the platform is also known as the e-Subaru Global Platform.
