The principal challenge in the coming years for car-making technology will be energy — the need to make vehicles that guzzle less gas and emit less CO2. A new form of mobility will emerge based not on a single solution but on the diversification of energy sources, with a sizeable share reserved for electricity and hydrogen fuel-cells. Toyota has decided to place hybrid motors at the center of its vision of this “smart” mobility in a society with vehicles connected to the Internet. This future mobility will have four pillars: safety, comfort, growing mobility and sustainable development.
