Volkswagen AG, already the biggest European car maker, aims to overtake Toyota Motor Corp. of Japan as the biggest worldwide in 2018 by selling 11 million vehicles, the German magazine Capital said.

VW, which sold 5.7 million cars and Trucks last year, expects to reach its goal primarily through increased sales of VW brand cars, which it hopes to boost from 3.6 million to 6.5 million in 10 years, said the report. Volkswagen also owns the Audi, Skoda and Seat brands.

Capital quoted what it said was a confidential VW document titled “Strategy 2018” that was reportedly approved by the VW supervisory board.
