Nissan shrugged off last year's natural disasters and a strong yen to post an operating profit of 545.8 billion ($8.7 billion) on a record 4.8 million vehicle sales, surpassing rival Toyota's financial performance for the first time.
And the number two Japanese vehicle-maker predicts it can do better this financial year, forecasting a further 10.4 per cent jump in vehicle sales to 5.35 million units, and a 9.5 per cent lift in operating profit, to 700 billion.
While Toyota's profit dived 31 per cent to 283 billion in the 2011-12 financial year ending March 31, Nissan's operating profit crept up 1.6 per cent on sales of 9.41 trillion - up 7.2 per cent, says industry website GoAuto.
Nissan's global vehicle sales surged 15.8 per cent from 4.18 million units last year to 4.8 million in 2011-12, partly on the back of increases in emerging markets, especially China - the company's biggest market - where sales jumped 22 per cent to 1.25 million vehicles.
In Brazil, sales grew 94.8 per cent to 81,000 vehicles, while in Indonesia volumes climbed 41.8 per cent to 60,400.
