Toyota NBC platform

The Toyota NBC platform is an automobile platform for subcompact cars (B-class cars) from Toyota.^[1] "NBC" stands for "New Basic Car". NBC platform made its debut in January 1999 with 1st generation Toyota Vitz. It is also often called "Vitz platform".

Features

• NBC cars can be either front-wheel drive or four-wheel drive.
• 4WD 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.
• Brakes are ventilated discs at front and drums at rear.

Models

• First generation Vitz family:
  • Hatchback: CP10 — Vitz (Japan), Yaris (EU), Echo (Canada).
  • Sedan: CP10 — Platz (Japan), Echo (Canada and US).
  • MPV: CP20 — Funcargo (Japan), Yaris Verso (EU).
• Various vehicles based on the first generation
  • AP10 — Toyota Porte (2004–2012)
  • CP19 — WiLL Vi
  • CP30 — bB (Japan) and first generation Scion xB
  • CP40 — Vios/Soluna Vios first generation

  • CP60 — ist (Japan) and Scion xA
  • CP70 — WiLL Cypha

Notes

• Second generation Toyota bB and Scion xB are no longer based on NBC platform:
  • Second gen bB uses smaller Passo/Daihatsu Boon "NC" platform (which is Daihatsu-rooted);
  • Second gen Scion xB utilizes larger MC platform.
• The third vehicle in the "Will" series — WiLL VS — was built on a larger MC platform.
• Most NBC-based vehicles use "CP" frame code. In fact, it can be either "CP", "SP" or "LP", depending on the engine:
  • for Z-suffixed engines (NZ, SZ) the second letter is "C" (e.g., NCP10);
  • for R-suffixed engine (KR, ZR) the second letter would be "S" (e.g. KSP90);
  • for diesel engine the second letter becomes "L" (e.g. NLP90).
