FRANKFURT (Reuters) -- General Motors is in talks with German carmaker BMW about using BMW's diesel engines in its Cadillac luxury cars in Europe, the Financial Times reported on Wednesday.
The paper said GM was also considering using engines made by its joint venture with Italy's Fiat, which are already used in its Saab cars.
It added that it was also possible that an Isuzu V-6 diesel engine used in the Opel/Vauxhall Vectra could be improved for the Cadillac.
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 finalized ahead of the Geneva motor show in March.
While both GM Europe and BMW declined to comment on the report, BMW has supplied GM Europe with six-cylinder diesel engines for the Opel Omega, and the German firm still delivers diesel motors to its former units Rover and Land Rover.
Cadillac has doubled its sales forecast for Europe to 20,000 cars by 2010.
