German brands are fighting a massive image problem that they need to redress at this year's Frankfurt Motor Show, reports Automobilwoche.

Automobilwoche was given exclusive access to some analysis by research company, Media Tenor, based in Bonn, Germany. Media Tenor examined press reports from 36 leading print media and television broadcasters between 1st January and 15 August 2005.

They found that Volkswagen received the most coverage but that more of the reports were negative than positive. Media Tenor assigned a percentage value to the net balance of positive versus negative reports. The Volkswagen figure comes out at -22%, perhaps not surprising given the recent corruption scandal.

DaimlerChrysler was the second most reported. Its overall result was -14%.

Nissan, Renault, PSA and Toyota topped the ranking.
