Building the future

Toyota New Global Architecture – a state of the art new way to build cars that are better for us, our customers and the environment

Our Always A Better Way philosophy is an expression that continuous improvement is possible, in fact it’s an essential part of any successful organisation. That’s why we’ve developed the Toyota New Global Architecture (TNGA). TNGA is an extension of the famous Toyota Production System, which is widely studied and admired for its efficiency. TNGA will help us build cars using standardised platforms, powertrains and major components, to make cars that require fewer resources to build, give a safer and more enjoyable drive, and have even greater fuel-efficiency.

A platform is the basic core around which the rest of a car is built. Globally, Toyota currently uses more than 100 uniquely modified platforms and sub-platforms, and 800 powertrains, including engines modified to fit those different platforms. But, with TNGA, just five layouts will be needed for the whole range, from compact sports cars to SUVs. The size and position of other key components will be standardised, too.

But that doesn’t mean that the cars will all look the same. Far from it, in fact. The standardised TNGA elements will be largely out of sight, giving Toyota designers the freedom to produce cars that are visually distinctive, as can be seen in the all new Prius and the C-HR Concept car – both of which were designed using TNGA.

As well as cutting-edge design, the TNGA-developed cars will give a significantly improved drive experience. The TNGA platform means low-stance designs, giving the cars a lower centre of gravity than before, which, in turn, will give better suspension, stability and handling. Strategic use of high-strength steel gives the new Prius a 60 per cent more rigid body shell, which also contributes to greater responsiveness as well as safety. And the new TNGA powertrains will increase fuel-efficiency by up to 15 per cent.

As TNGA-built cars will be able to use many uniform parts, fewer components will need to be designed, produced and shipped. The cars will also need 20 per cent less manpower to build – freeing up a significant amount of time that can be devoted to designing new cars. Fewer components and less manpower will make factories greener too, which is obviously better for the environment.

Looking to the future, TNGA will be the foundation for all Toyota’s powertrain and vehicle development, and by 2020 half of Toyota’s will be built using TNGA.

On progress made so far, Toyota President Akio Toyoda said: “I want 2015 to be a year in which we take steady and bold steps toward sustainable growth. We can do this by launching new models that incorporate TNGA, and making good use of this intentional pause to strengthen our competitiveness. We aim to be a company that grows sustainably – a tree with a strong trunk.”
