After considering the possibility of selling Porsche earlier this year, Volkswagen AG has received an offer for Lamborghini.

Volkswagen reiterated plans not to sell Lamborghini after British weekly magazine Autocar said it got an offer of 7.5 billion euros ($9.2 billion) for the brand, Bloomberg reported Wednesday.

The nonbinding offer sets out conditions for the acquisition of Lamborghini by Switzerland's Quantum Group AG, which has formed a consortium with London-headquartered investment company Centricus Asset Management, Reuters said, quoting the Autocar report.

The report, quoting offer documents, said the consortium would offer job guarantees for existing Lamborghini workers for up to five years and the creation of 850 new jobs.

According to The Detroit Bureau, Volkswagen has been evaluating its holdings portfolio in recent months as the company tries to decide what to get rid of and what to keep. Volkswagen is reportedly close to selling Bugatti to Croatian hypercar maker, Rimac.

Lamborghini is owned by the Volkswagen group through its subsidiary Audi.

"This is not the subject of any discussion within the group. Lamborghini is not for sale," Bloomberg quoted a representative from Audi as saying.

Representatives of Quantum Group and Centricus were not immediately available for comment.

The reported offer for Lamborghini comes in the wake of uncertainty over whether VW will keep a sprawling structure that includes brands like Ducati, Porsche, Bugatti and Audi, according to Reuters.

Stephan Winkelmann, Lamborghini chief executive officer, last week said the brand planned to invest $1.5 billion to build a fully gas-electric hybrid vehicle by 2024.
