This is a continuation of a report series describing the teardown analysis of the all-new Prius performed in January 2016 by the Hiroshima Industrial Promotion Organization. The first report can be found at the following.
(4th-Generation Toyota Prius Teardown (Part 1): Powertrain units miniaturized and lightened to achieve 40km/liter fuel economy)

This report will introduce the TNGA (Toyota New Global Architecture) platform, as well as its chassis and aerodynamic technologies, which have significantly advanced the Prius's driving performance. Fuel economy was given priority in previous Prius models, but attention was given to areas related to driving performance as well in the 4th-generation Prius, and thoroughly planned out technology that rivals European cars has been worked in throughout the vehicle.


A third report will introduce the autobody and sound insulating technologies in the new TNGA platform.
