According to Reuters, Volvo said in a statement that deliveries of its Mack brand rose 55%, totalling 23,675 units.

"The deliveries figures continue to reflect the strong order intake seen in the first part of 2005. Buying interest remains high among customers in Mack's core segments of construction, refuse and economic haul," the group said.

Reuters said Renault Trucks was up 10% to 46,835 units, with the biggest increase seen in markets outside Europe.

North America registered a rise of 66% while South America rose 75%.

Volvo Trucks' deliveries rose 18% during the period to 67,472 vehicles.

"North America continues to perform highly favourably, with a rise of 35%, as well as the Middle East, posting an increase of 61%," it said, according to the news agency.

"Deliveries to markets in Europe of heavy trucks are still at historically very high levels and to date this year increased by 2%," the group added.

In eastern Europe, a sharp rise was seen in Russia, up 76% to 715 trucks so far this year, it said, according to Reuters.
