Toyota posts record group net profit for Apr.-Dec.

Toyota Motor has posted a record group net profit for the first nine months of the fiscal year.

Japan's largest automaker cites robust global unit sales led by hybrid models and the weaker yen as the main factors.

Toyota says its group net profit for the April-to-December period more than doubled from the previous year to 3.94 trillion yen. That's roughly 27 billion dollars.

Group sales also hit a record high of 34.02 trillion yen, or about 230 billion dollars. That's up nearly 24 percent.

Toyota has raised its group net profit forecast for the full year through March to 4.5 trillion yen, or about 30 billion dollars. It would be the first time ever that the figure tops the 4-trillion-yen mark.

The upward revision comes even though the company cut its full-year unit sales outlook from 9.6 million to 9.45 million.

The production of some models has been suspended due to testing irregularities for vehicle certifications at group firms Daihatsu Motor and Toyota Industries.
