Toyota GA-B platform unveiled, likely to underpin new Yaris

Of course, the TNGA (that's Toyota New Global Architecture) platform is already employed in GA-C guise by the likes of the Prius, C-HR, Corolla and Lexus UX. The Japanese firm claims its focus is to "elevate the design and driving performance of small cars".

Like the GA-C and GA-K versions of TNGA, the GA-B platform is designer to "deliver a confident and natural drive", as Toyota explains.

Most significantly, though, the GA-B platform allows for variable wheelbase lengths, widths and heights, suggesting that Toyota will eventually expand its small vehicle line-up beyond the Yaris with different bodystyles. For starters, advanced joining technologies provide high levels of underbody rigidity, while keeping weight and cost in check.

MacPherson strut suspension up front and either a torsion beam or multi-link setup at the rear is how the GA-B was engineered, promising "smart packaging and design freedom" according to the vehicle type and character.

The automaker furthermore says the GA-B platform positions the driver's seat low and back towards the centre of the vehicle, resulting in an "engaging driving position" with a steering wheel that can be set close to the driver at an "optimised" angle. Toyota even makes a case about how the steering wheel is positioned and what angle, and that's a bit too much information given the tilt-and-telescoping functions of most steering columns out there. The TNGA philosophy uses standardised components in out-of-sight areas, simplifying the vehicle design process without creating look-alike cars. Positioning the wheels at the corners of the platform and very short overhangs add to the visual appeal this generates.
