Volkswagen (VOWG_p.DE) has received a 7.5 billion euro ($9.2 billion) offer for Lamborghini, British weekly magazine Autocar reported on Tuesday, though VW's Audi said the supercar brand was not for sale.

The non-binding offer sets out terms for the purchase of Automobili Lamborghini by Switzerland's Quantum Group AG, which has formed a consortium with London-based investment firm Centricus Asset Management, Autocar reported.

The report, citing offer documents, also said that the consortium would include job assurances for existing Lamborghini employees for up to five years and the creation of 850 new jobs.

Quantum Group founding partner Rea Stark is also co-founder of Piech Automobile with Toni Piech, the son of former Volkswagen Chairman Ferdinand Piech, according to its website.
