Volkswagen Group said global deliveries for its cars and commercial vehicles rose 6 percent in April and 8.
9 percent in the first four months, but warned that it expects growth to slow down for the rest of the year due to the European market slump.
Deliveries by the group's brands, from luxury carmakers Audi and Bentley to volume brands VW, Skoda and Seat, rose to 732,000 in April, compared with the same month in 2011 and to 2.89 million year-to-date.
Group sales chief Christian Klingler said: "We expect the markets in western Europe to deteriorate further. Our current projection has been adjusted downward and we are therefore keeping an even closer eye on market developments."
