Sales at DaimlerChrysler's premium Mercedes Car Group rose 2% in April to 104,900 units, helped by the first monthly rise in deliveries of its core Mercedes-Benz brand this year, Reuters reported.

DC said on Friday that sales of Mercedes-Benz cars increased 1% to 92,400 vehicles, while deliveries of Smart compacts gained 9.7% to 12,500 cars, the report said, adding that the division's sales fell a cumulative 2.7% in the first four months to 366,500 vehicles.

According to Reuters, DC said its Mercedes model offensive has started to bear fruit, with "excellent" demand for its new B-class compact sports wagon that will hit dealerships in western Europe in June.

"Roughly four weeks before the market launch of the new B-Class, there are already more than 20,000 orders from western Europe," it said in a statement cited by the news agency.
