Volvo is the first mainstream automaker to make the leap. By 2019, they aim to have no cars that rely on the internal combustion engine alone for power. While they are not ready to commit to purely electric cars, the only ICE’s they will sell will be mated to some sort of hybrid drivetrain.
They are planning five new models that rely on electrification of some sort to help move the company into the future. Volvo also famously promised “deathproof” cars by 2020, so they are nothing if not ambitious. Volvo is often overlooked and their emphasis on hybrid and electric vehicles is a strong indication that they recognize their need to evolve to stay relevant.
