BMW, the German maker of luxury cars, said on Friday it sold a record 150,285 cars worldwide in June, 15.1 per cent more than in the same month last year and ahead of arch rival Mercedes built by DaimlerChrysler.
"Never before in our history have we sold so many automobiles in one month," BMW boasted in a statement.
Europe remains BMW's biggest market, with unit sales there jumping by 15.9 per cent to 90,310 cars in June.
But it was China, where the luxury car maker clocked up its strongest growth, with unit sales zooming ahead by 63.2 per cent to 5,925 cars last month.
BMW's Mini also set a new record last month, with sales of the up-market small car rising by 19.4 per cent to 22,465 units in June.
Sales of the BMW brand alone rose by 14.4 per cent to 127,747 cars, while the group sold 73 Rolls Royce Phantoms, unchanged on the year, the statement said.
Taking the period from January to June as a whole, BMW sold a total 730,285 of its BMW-brand, Mini and Rolls-Royce cars worldwide, a rise of 4.6 per cent of the year-earlier period.
Earlier this week, DaimlerChrysler said that worldwide sales of its Mercedes brand cars declined by 1.3 per cent to 117,200 units in June as a result of a shake-up of the model portfolio of its ultra-compact Smart cars.
And taking the six months to June, DaimlerChrysler's customer deliveries were down by 1.5 per cent at 617,700 units.
