Germany′s top car makers have built up an international reputation, says David Fitzgerald, an analyst at PFPR Communications.

He said, "The German focus on engineering quality has built up their reputation over years for instilling confidence in consumers who choose their products and that′s a real lasting impression for their customers."

This is now paying dividends for the likes of BMW, Mercedes, Audi and Porsche.

They′ve had a record 2011 so far thanks to demand in emerging markets, especially China.

VW has ten auto brands including Porsche and Audi - and Volkswagen Group CEO Martin Winterkorn says there′s a reason their products sell well at home and abroad.

He said, "The German car industry and especially Volkswagen have done their homework. We′ve invested a lot of money in new technology, in lightweight design, in electronics, electric motors, hybrid motors, fuel cell vehicles and that′s why I think we′re the global benchmark."

China′s now the world′s top car market and it's also increasing car production.But analysts say the South Koreans are now entering the fast lane.
