Most vehicles sold feature an internal combustion engine running some type of fuel, but a Toyota executive believes this engine will be gone for vehicles by 2050.
“We expect that by 2050 we will have reduced CO2 emissions from vehicles by 90% compared to the figure in 2010. 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,” said Seigo Kuzumaki, Toyota’s head of advanced R&D and engineering.
Kuzumaki's reasoning for this comes down to governments tightening regulations on emissions. This, in turn, will cause automakers to accelerate development of alternative powertrains such as electrics.
Toyota's a latecomer to electric vehicles, instead choosing to focus on hydrogen. But the Japanese automaker is working on a new family of EVs that will launch in 2020. The models will use lithium-ion batteries and have a range of 300 miles. But Toyota hopes to launch solid state batteries only a few years later for their EVs. Solid state batteries use solid electrolytes instead of liquid to hold a charge. This will provide better performance and a smaller size than the lithium-ion battery packs.
