Common Process. Common Parts.
At its core, Toyota New Global Architecture (TNGA) is about building ever-better vehicles on common platforms with common parts. The aim is to make our manufacturing plants more flexible and responsive to changes in the marketplace.
This flexibility will lead to cost savings that can then be reinvested in future technologies, giving rise to the next generation of ever-better Toyota vehicles. And, in turn, the next. And the next …
2018 Toyota Camry XSE
Most North American-produced vehicles will adopt TNGA during their next full model changes.
The 2018 Camry will be the first TNGA-inspired vehicle assembled in North America, at Toyota Motor Manufacturing, Kentucky.
Toyota Motor Manufacturing de Guanajuato, scheduled to start production in 2019, will be Toyota's first North American manufacturing plant built from the ground up with TNGA capabilities.
In 2020, approximately half of all new Toyota vehicles worldwide will benefit from TNGA.
The current Prius, assembled in Japan, represents the first fruits of TNGA.
TNGA is built upon two pillars — Core Strength and Emphasized Personality. Improvement of the basic performance of the core (essential parts) raises the level of all Toyota vehicles. By sharing high performance components, chief engineers are able to focus on accentuating the appeal of each model.
The platform (the part that's hidden) is shared across multiple models.
Shared by such vehicles as Prius, C-HR, and Corolla.
Shared by such vehicles as Camry, Avalon,
The upper body (the part that's visible) varies by model and market.
Enhanced visibility and legroom.
Promotes more athletic /
Lower and wider
Lower center of gravity
Reduced side-to-side rolling
More responsive steering
Lighter/more compact engines and transmissions
Conventional and hybrid powertrains that are more powerful and more fuel efficient.
Hybrid powertrains that are more fuel efficient.
Reduced vehicle fuel
consumption (new powertrains).
Reduced vehicle emissions
Reduced weight by adopting new materials such as high strength steel and aluminum
TNGA will shorten the development cycle for vehicle improvements and new vehicles.
That means better options when it's time to buy a car.
Shared parts/components means assembling multiple vehicles on the same line. Initial investment in assembly plants can be as much as
40 percent less compared with today's standard.
Ideal TNGA plant: produces 200,000 units annually, can build up to 8 different models on flexible lines and minimizes difficult tasks, making it easier to operate and maintain.
Reduced plant electricity consumption (LED lights, skylights, solar panels)
Laser screw welding vs. traditional spot welding
Paint shop that is smaller, easier to install and modify and lower in cost (example: height of paint booth can be just 6 meters compared to current 10-13 meters).
Reduced plant water usage (smaller paint booth, rain water recycled for plants).
Reduced plant waste (shift toward lower sludge producing metal oxide phosphate paint chemicals).
Plastic mold machine that makes one-piece bumpers.
Example: could churn out a Camry bumper, then an Avalon bumper, then a Camry bumper one at a time based on production demand vs. batch production; goal is just-in-time delivery and minimal inventory.
Assembly line components are bolted to the floor so they can be picked up and moved as needed. Can make the line longer or shorter over a weekend.
Shift toward shorter assembly lines, augmented by subassembly done off the line (such as cooling system, instrument panel)
help boost body stiffness, contributing to better handling.
