Volvo also raised its North American commercial-vehicle market forecast, citing a "robust manufacturing environment" as consumer spending bolsters US economic growth.

The European market will rise to 240,000 vehicles from the 228,000 delivered last year, versus an earlier forecast of no growth.
"We do see some light spots in the economy and also in the truck market" in Europe, Persson said on a conference call with reporters.
While the North American outlook was as expected, "the European forecast seems ambitious, as it assumes very strong demand during the second half of 2015", Wodniok said.
