Toyota C-HR Teardown: 1.2-liter downsized turbo engine

Internal combustion engine (ICE) with high thermal and fuel efficiency

2018/11/05

Summary

 The long-awaited introduction of the C-HR into the intensely competitive compact SUV category has resulted in increased sales volumes, especially in the European market, with its stylish design and TNGA technologies that realize high maneuvering stability and best-in-class levels of fuel economy performance. The C-HR launched for the Japan market is powered by the newly developed engine (Model 8NR-FTS: Euro bio-gasoline compliant) equipped on the Auris released in Japan using the same 1.2L downsized turbocharged engine. However, this engine uses regular gasoline fuel.

 This engine is a representative Toyota production engine with high thermal and fuel efficiency, which Toyota aims to make the world’s top engine in terms of performance with a 10% improvement in fuel economy and maximum thermal efficiency.

 This report serves as a commentary on the direction of gasoline engine technology at Toyota amidst advances in electrification and technologies related to HEVs, PHEVs, and EVs, and is based on the teardown analysis of a Japan-spec C-HR as well as Toyota publicly released materials (e.g. seminar presentation entitled Toyota’s New, More Efficient Engines).

 This Toyota C-HR vehicle teardown analysis report was conducted in 2018 as part of the benchmarking activities of the Hiroshima Industrial Promotion Organization. MarkLines Co. Ltd. has an agreement with the Hiroshima Industrial Promotion Organization for the publication rights and sale of its benchmarking reports.
