General Motors' sales in Europe fell 7.5 percent in April to 164,191 vehicles, led lower by a 10.8 percent drop in Opel/Vauxhall registrations, the world's leading carmaker by volume said on Monday.
The group's European market share slipped to 9.1 percent from 9.4 percent in April 2005. Sales in the first four months eased 0.7 percent to 686,468 vehicles as GM focused on improving revenue per unit, it said.
"Overall, our sales performance in Europe is on track for the first four months of the year. We saw mixed share results in certain important markets. For example we are looking to improve our German market share," said Jonathan Browning, GM Europe's head of sales and marketing.
Opel and its sister British brand Vauxhall, which contribute the bulk of GM sales in Europe, saw combined sales slip 3.4 percent in the first four months, reducing their market share in Europe to 7.5 percent from 7.9 percent a year earlier.
Sales growth at Swedish brand Saab decelerated to 2.3 percent in April, but four-month sales still rose by more than a fifth to nearly 32,000 cars.
The Chevrolet brand continued its sales advance in April, with registrations up 8 percent at more than 28,000 vehicles. Sales topped 103,000 in the first four months.
