Toyota Motor Corporation recently announced that cumulative global sales of its hybrid vehicles topped the 6 million unit mark at the end 2013, reaching just under 6.1 million units.

The latest “million-unit milestone” was achieved in the fastest time yet for Toyota, taking just nine months. Toyota currently sells 24 hybrid passenger car models and one plug-in hybrid model in approximately 80 countries and regions around the world. Within the next two years, Toyota plans to launch 15 new hybrid vehicles worldwide, including the new Harrier Hybrid in Japan on January 15 and the new Highlander Hybrid in the United States in the near future.

Toyota calculates that as of the end of December 2013, the company’s hybrid vehicles have resulted in approximately 41 million fewer tons of CO₂ emissions than would have been emitted by gasoline-powered vehicles of similar size and driving performance. Toyota also estimates that its hybrid vehicles have saved approximately 15 million kiloliters of gasoline compared to the amount used by gasoline-powered vehicles of similar size.
