Toyota NBC platform
# Toyota NBC platform

The Toyota NBC platform is an automobile platform for subcompact cars (B-segment cars) from Toyota. "NBC" stands for "New Basic Car" or "New Basic Compact". The NBC platform made its debut in January 1999 with the first generation Vitz; as such, it is also called the "Vitz platform". It is replaced by the newer B platform.

## Features

* NBC cars can be either front-wheel-drive or all-wheel-drive.
* AWD variants use V-Flex II system, which is a viscous-coupling torque-on-demand.
* Engines are mounted transversely.
* Front suspension is MacPherson strut, while rear is torsion beam.
