Toyota Motor Corp. sold 4.8 million vehicles worldwide in the first half of the year, up 2 percent from the same period a year ago, the Japanese automaker said Wednesday. Toyota's global vehicle sales have been about the same recently as those of US-based General Motors Corp., the world's top automaker in annual sales for 76 years straight. Toyota overtook GM in the first quarter, selling 2.41 million vehicles to GM's 2.25 million. Toyota spokesman Hideaki Homma said the company sold 4,817,941 vehicles globally during the first six months of the year. GM was expected to release figures later in the day. Automakers have been struggling lately to maintain sales momentum amid soaring motor fuel prices. Toyota has a reputation for high-mileage cars such as its hit gasoline-electric Prius hybrid, but it is still facing the challenge of sluggish auto markets in the US, Europe and Japan. Expectations have been high that the pace of Toyota's recent global sales growth will diminish despite stronger sales in emerging markets, such as India. Toyota has said it expects to sell 9.85 million vehicles worldwide this year, up 5 percent from last year. But it may lower that target when it updates its strategy next month. Toyota has been aggressively working to boost production of smaller, fuel-efficient vehicles to meet changing consumer tastes. Earlier this month, it announced sprawling manufacturing changes in the US, including starting production of the Prius for the first time, and shutting down truck and sport utility vehicle production. Toyota said it plans to produce the Prius - now made only in Japan and China - in Mississippi by 2010, and will consolidate US truck production in San Antonio. General Motors is also reshaping its US production, closing plants and reducing pickup and SUV production. Last month, all major automakers except for Honda Motor Co. reported steep sales declines in the US for the worst June in the industry in 17 years. Toyota officials say they are looking for growth outside the US and Japan. Last week, it said it is acquiring land in Brazil for a plant likely to start making compact vehicles as early as 2011. The plant, Toyota's second in Brazil, will create about 2,500 jobs and have initial annual production capacity of 150,000 vehicles, according to Toyota. The switch to smaller vehicles is almost certain to bite into the profits at automakers because profit margins are heftier for bigger models. GM has been losing billions over the last three years.
