General Motors is talking with BMW about using diesel engines in Cadillac models in Europe, Reuters reported, citing the Financial Times.

The paper reportedly said GM was also considering using engines made by its joint venture with Fiat, which are already used in Saabs.

It added that it was also possible that an Isuzu V6 diesel engine used in the Opel/Vauxhall Vectra could be improved for Cadillac, Reuters said.

The report said the paper cited people close to the discussions as saying a decision was not imminent, but added that GM vice chairman Bob Lutz had indicated it could be finalised ahead of the Geneva motor show in March.

BMW has previously sold diesel engines to General Motors Europe for installation in the Vauxhall/Opel Omega line, which is no longer made.
