General Motors' global car sales outstripped Toyota in the last quarter, the two companies have said.
America's GM has regained its place as the world's top-selling automaker, a position it had held since before the second world war until the start of this year, after 2.405 million of its vehicles were bought globally in the last three months.
Its Japanese rival Toyota meanwhile sold 2.367 million during the same period.
But the Detroit-based firm saw its US market share shrink 1.3 points on the half year to 23 per cent.
Toyota meanwhile, which first overtook GM in global sales in the first quarter of this year, enjoyed a 16.1 per cent share in the US market during the last six months, compared to 14.6 per cent in the corresponding period last year.
GM vice president John Middlebrook nevertheless emphasised the "exceptionally-strong demand" in emerging markets that the firm had witnessed over the last quarter.
"In the second quarter we experienced record sales growth around the globe including 20 per cent growth in Latin America, Africa and the Middle East an all-time quarterly record for that region, and eight percent growth in the Asia Pacific region," he said.
"We're also pleased to see almost five per cent growth in Europe where we sold more than 574,000 vehicles."
