Net profit jumped 53 percent year-on-year to €1.84 billion in the three-month period to September as income tax payments fell.
Operating profit rose 16 percent to €2.23 billion, slightly better than a forecast of €2.07 billion from analysts polled by Dow Jones Newswires.
"This shows that the high investments we have made were money well spent," said chief executive officer Dieter Zetsche.
The Stuttgart-based company gave a forecast for the full year, predicting earnings before interest and tax at about €7.5 billion, below the previous year's €8.1 billion.
Previously the company had only said profit would decline as it invests in new models.
