Volkswagen is likely to keep its Bugatti and Lamborghini brands, despite rumors of a possible sale or spin-off. Martin Winterkorn, VW's new boss, told a German newspaper research and development done at the two supercar brands can benefit the entire company.

Winterkorn told the daily Suddeutsche Zeitung that "development in the upper segments undertaken by Lamborghini and Bugatti has been advantageous for all the brands."

He also praised the technological achievements of Bugatti, which is struggling to become profitable. "A jumbo jet takes off at 250 km/h, whereas a Bugatti remains safely on the ground at 400 km/h."

A recent comment by Porsche AG CEO Wendelin Wiedeking suggested he would pressure VW to drop the brands "" "no toys anymore," he said. Porsche has a large investment in VW and some board control. The sports car maker is seeking to expand that control further.
