Many used the North American International Auto Show (NAIAS) in Detroit to showcase forthcoming launches.
The German automotive industry association, the VDA, described the US automotive market as the most important in the world which is expected to expand to about 17 million vehicles in 2004.
VDA president Bernd Gottschalk said: 'We hope that this growth, which is being aided by the recovery of the US economy, will be accompanied by a calmer period on the 'rebate front'.'
He added: 'German vehicles are setting the standards in technology, quality and design on the highly competitive US market. This combination, together with the most modern exhaust standards and attractive consumption values, is something that no-one in the world will imitate in a hurry.
'In 2003 the German manufacturers were able to increase their market share in the USA. We will build on this in 2004.'
On the subject of the dollar's current low exchange rate Gottschalk said: 'It does affect us, but does not upset the applecart.'
The VDA says the success of the German car makers in the USA is based above all on the innovative and attractive range of models, which is continually being expanded.
