VW to clean Porsche?

Under American rules, Ford reports Mazda fuel economy data as its own, even though it has only a minority stake in the Japanese car company, and DaimlerChrysler used to do the same with Mitsubishi. Porsche is currently struggling to meet an average fuel economy standard under US law, and the motor trade magazine Automotive News has been speculating that Porsche may be seeking to merge its data with VW’s to achieve a legal average in the USA. • Porsche’s environment manager Herbert Ampferer says it is ‘impossible’ for the company to meet the proposed EU CO₂ reduction target without ‘abandoning its market identify’.
