Internal combustion engine to be dead by 2050, says Toyota R&D boss

Toyota expects the internal combustion engine to be dead by 2050, and power only about 10% of cars as part of hybrid systems from 2040 onwards.

The prediction, announced by Seigo Kuzumaki, Toyota’s head of advanced R&D and engineering, re-emphasises that car makers are expecting global emissions regulations to tighten, and electric car development to accelerate, at a pace that will end the sale of combustion engined cars globally by that point.

“We expect that by 2050 we will have reduced CO2 emissions from vehicles by 90% compared to the figure in 2010,” said Kuzumaki. “To achieve that from 2040 simple internal combustion engined cars will not be made, but they may be the basis of some hybrid or plug-in hybrid cars.” 

Kuzumaki’s comments also reconfirm that the announcement in July by UK Environment Secretary Michael Gove that the sale of new combustion-engined cars would be banned by 2040 - subsequently clarified the same day to state that new hybrid cars would be allowable - is likely behind car makers’ own planning, because it is in line with Toyota’s goals for both developed and developing economies.

At present, Toyota sells around 43% of all electrified vehicles globally, with the Toyota Prius being the best selling electrified vehicle in the world, with more than 11m sales to date. The best-selling full electric vehicle, the Nissan Leaf, currently sells around 50,000 units annually.

Toyota is planning the launch the first of a family of electric vehicles from 2020. Although the early models are expected to use lithium ion batteries and fall in line with the industry-standard of around 300 miles of range, it expects to have be able to productionise solid state batteries by “the early 2020s” according to Ise.

The arrival of solid state batteries is seen by Toyota as a key breakthrough in electric car technology; they are smaller, safer and will offer substantially greater performance than today’s units.

“We hold more patents on solid state batteries than any other company,” said Kuzumaki. “We are getting close to developing cars using the technology, and we believe that we will be ahead of our rivals in achieving that.”
