Toyota has revealed improvements to its engine range to fit with its TNGA (Toyota New Global Architecture) underpinnings.
High amongst the list of prioritised changes is a focus upon driver engagement and enjoyment, in addition to better fuel economy by up to 20%, up to 15% lower emissions of at least 15 per cent, and 10% more power. Toyota aims to introduce the range from 2017 onwards.
This efficiency is partly due to Toyota’s measures employed to lighten the engines, and ensure that they give cars they're used in a low centre of gravity. The manufacturer claims that the new raft of engines could “change how Toyota cars drive”.
Included in this new raft of engines is a new, 2.5-litre direct-injection inline four-cylinder petrol engine, part of a range which Toyota calls ‘Dynamic Force Engines’, which use high-speed combustion and other efficiency-based technologies.
Lower friction has also been designed into moving parts for greater fuel efficiency; Toyota claims efficiency ratings of 40% and 41% for the petrol and petrol hybrid versions of this engine respectively. It will not be offered as a diesel.
