KEY POINTS:
Toyota's groundbreaking Prius petrol-electric hybrid celebrates its 10th birthday this month.
Since the first-generation model made its debut in Japan in 1997, about 900,000 Prius models have been sold.
The launch of an all-new Prius in 2004 was followed by the announcement that Toyota had commissioned a new production centre in Changchun, China.
The Prius remains the world's best-selling hybrid power vehicle. Toyota Motor Corporation has also expanded its hybrid model range to include off-roaders, people-movers and luxury saloons in its Toyota and Lexus ranges.
