Profit was 4.82 billion kronor (500 million euros, $544 million), and  adjusted operating profit was 7.03 billion, exceeding the 5.31 billion mean  forecast by analysts in a poll by the SME Direkt agency.

Gothenburg-based Volvo Group delivered fewer lorries than a year before (-4 percent in volume), a period when its clients rushed to buy them just before new and more expensive environmental norms were implemented.

This was off-set by 34 percent higher volumes of construction equipment.

"The good order trend from the end of last year continued, with order intake for trucks being up by 11 percent to 55,600 vehicles," Volvo Group CEO Martin Lundstedt said in a statement.

The first quarter was helped by sales of construction equipment (Volvo CE), where volumes delivered as well as orders increased by 34 percent, which Volvo attributed to the "recovery in the mining industry".

Overall, turnover jumped by eight percent to 77.37 billion kronor for Volvo, whose cost trimming in recent years boosted its profitability in the first quarter.

The operating margin, at 9.1 percent, climbed 1.6 percentage points in one year.
