Toyota Brings TNGA To Small Cars With New GA-B Platform

Toyota Brings TNGA To Small Cars With New GA-B Platform

  • Engineered to deliver a confident and natural drive
  • Smart packaging for increased space and design freedom
  • Modular system to allow a variety of vehicle sizes and body types
Toyota’s development of new platforms under the Toyota New Global Architecture (TNGA) philosophy has delivered a step-change in the ride, handling and styling of a series of recent new models.

The first, the GA-C platform for mid-sized cars is the foundation for advances in the driving character and appeal of the latest generation Prius, the C-HR and the newly launch Corolla.

Similarly, the TNGA philosophy has demonstrated its capability for larger sedans and SUVs, with the GA-K platform underpinning the new Camry and the new RAV4 to great effect.

Now, Toyota is preparing to apply the philosophy and technology of TNGA to elevate the design and driving performance of its small cars with the debut of the GA-B platform.

Confident & Natural Driving

In common with the GA-C and GA-K platforms, the new GA-B platform is designed to deliver a confident and natural drive. 

This is achieved through a number of techniques. First of all, the platform features advanced joining technologies that contribute to high levels of underbody rigidity whilst maintaining a focus on weight and cost.

Secondly, the MacPherson strut front suspension features low friction dampers and a variety of spring types. The rear suspension can be specified as either torsion beam or multi-link design depending on vehicle character and type.

Last, but not least, the GA-B platform also positions the driver’s seat low and back towards the centre of the car, helping to reduce the vehicle’s centre of gravity. This also creates an engaging driving position with a steering wheel that can be set close to the driver at an optimised angle.

 

Smart Packaging & Design Freedom

The new GA-B platform has also been designed to maximise interior space through its approach to smart packaging delivering a spacious and comfortable interior.

The TNGA philosophy positions non-visible components to simplify vehicle design in key areas. As a result, vehicle designers will have the freedom to give each new GA-B model a visually distinctive and individual look with a low stance and appealing proportions.

In addition, the upper body hard points and the driver’s hip point are positioned low to give designers further freedom to create vehicles with a low height and wide stance.

This kind of visual appeal is aided by the positioning of the wheels at the platform corners, with very short overhangs.

And the combination of a long wheelbase architecture and a smart approach to packaging ensures that interior space is not compromised despite possible compact exterior dimensions.

 

Modular System

The new GA-B platform offers a great deal of modularity, with a variety of wheelbase lengths, vehicle heights and track widths, allowing designers and engineers to create appealing vehicles of different sizes and body types.
