Volkswagen Group deliveries rose 4 percent to 859,400 in June as renewed demand in Europe and strong sales in China helped offset declines in the United States and South America.

Six-month sales were up 6 percent to 4.97 million vehicles as the automaker’s VW, Audi, Porsche, Seat and Skoda brands all reported robust growth.

“Volkswagen Group is entering the second half of the year with confidence. But we are also well aware of the tasks that lie ahead,” Christian Klingler, VW’s sales chief, said today in a statement, adding that the situation in some world markets remained “tense.”

VW Group’s six-month sales in Europe grew 7 percent to 1.99 million vehicles. Deliveries in western Europe rose 8 percent to 1.05 million, with German sales increasing 5 percent to 613,200. In central and eastern Europe, sales were up 6 percent to 331,300. Russian sales were down 9 percent to 137,200 through June.

In China, the carmaker’s largest-single market, sales were up 18 percent to 1.81 million.

U.S. deliveries fell 5 percent to 288,000. In South America, sales were down 22 percent to 350,800, with an 18 percent drop to 271,700 in Brazil.

VW brand’s volume increased 4 percent to 3.07 million in the first six months, while Audi’s deliveries jumped 11 percent to 869,400. Porsche sales rose 8 percent to 87,800, while Skoda deliveries climbed 13 percent to 522,500, boosted by sales of its new Octavia compact.
