Ford B3 Platform

B3 is the name of a Ford Motor vehicle architecture designed to underpin subcompact cars and SUVs. It succeeds the Ford B and Mazda D platforms and marks the entry level line of vehicles within Ford’s portfolio. Its top priorities are being simple, compact and above all, cheap to build.

This platform is currently still in production for vehicles sold under the Ford nameplate worldwide. Here are the Ford vehicles currently sold in the U.S. and worldwide that ride on the Ford B3 platform:

Future Models

There are currently no expected new models for the Ford B3 platform.


The Ford Fiesta will be phased out in the U.S. and Canada at the end of 2019. The Ford EcoSport was released in the U.S. and Canada as a new model for the 2018 model year and is currently available for order.

However, the EcoSport has been on sale in other markets since 2013. It could soon be heavily updated.
