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 recent models.
The first, the GA-C platform, underpins the latest-generation Prius, the C-HR and the newly launched Corolla Hatch, while the GA-K platform is used for the new RAV4. 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.
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.
CONFIDENT & NATURAL DRIVING
Like 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:
• Advanced joining technologies This contributes to high levels of under-body rigidity while maintaining
a focus on weight and cost.
• MacPherson strut front suspension It 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.
• Seating position 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. This kind of visual appeal is aided by the positioning of the wheels at the platform corners, with very short overhangs.
The combination of long wheelbase architecture and a smart approach to packaging ensures that interior space is not compromised, despite possible compact exterior dimensions.
