BMW's CFO Friedrich Eichiner told Germany's Frankfurter Allgemeine Sonntagszeitung that the carmaker sold over 100,000 cars last month.
Despite turmoil on the financial markets sparked by fears of a looming recession, the company is planning to stick to its sales targets.
"We see no reason to lower expectations, and we are confident about reaching our goals," Eichiner said. "We want to sell more than 1.6 million cars in 2011, and after the first half of the year, we're completely on track."
Audi AG, part of the Volkswagen Group, also raised its annual sales forecast at the weekend.
"We will clear the bar of 1.2 million sales cleanly," Audi CEO Rupert Stadler told Automotive News Europe.
Stadler said Audi was trying to grow the company in hopes of reaching a 2-million-car sales target in the year 2020. The carmaker is looking to sell 1.5 million cars in 2015, a goal that the Audi CEO said it would probably reach by 2014.
"We have nothing against it happening earlier," Stadler said.
Audi's competitor Daimler is also feeling confident about its 2011 sales results, with CEO Dieter Zetsche telling the magazine that the company expects to sell more than 1.35 million vehicles.
Daimler sold nearly 1.2 million cars in 2010.
