TNGA stands for Toyota New Global Architecture, and so far, there are numerous derivates for front-, rear-, all-wheel drive applications such as passenger cars, utility vehicles, and minivans. The series started in 2015 with the TNGA-C in the Prius, but not long now, the TNGA-B will underpin small cars and crossovers.
B stands for the B-segment, a European classification with the American equivalent of the subcompact class. Think Honda Fit and HR-V, Volkswagen Polo and T-Cross, all that jazz. Given that the Toyota C-HR rides on the GA-C variant of the modular architecture, the GA-B has great potential going forward.
Variable wheelbase lengths and track widths lead us to believe the Toyota FT-4X concept will utilize the all-new platform. Hearsay suggests that Toyota will also manufacture the FT-4X small crossover in Huntsville, Alabama at the production facility owned by the Japanese automaker with the peeps at Mazda.
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 next generation of the Yaris could also be underpinned by the GA-B modular platform.
“The GA-B platform also positions the driver’s seat low and back towards the center of the car,” therefore enabling a lower center of gravity compared to the outgoing vehicle architecture. 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.
On that note, take a look at how short the rear overhang is. The front isn’t too shabby either when compared to current-generation models, and that should translate to easier maneuvering and better handling all around.
Toyota doesn’t mention a thing about the type of assistance for the steering, but we’re almost certain that electric assistance is the norm. Certain driver-assist systems rely on this setup, and Toyota plans to have a self-driving car on the road in a year’s time according to the chief exec of the TRI-AD division.
