BERLIN -- Audi has placed its plans to enter Formula One under review, German news outlet Spiegel reported.
Citing sources at parent company Volkswagen Group, Spiegel said the plans were being "analyzed in detail" in the wake of a management change and cost-cutting measures.
Audi announced last year that it would enter Formula One from 2026 and that it had taken a minority stake in the Sauber Group, whose Swiss-based team is competing this season as Alfa Romeo with Ferrari engines.
Audi is making its own Formula One power unit at a facility in Neuburg an der Donau, near the automaker's headquarters at Ingolstadt.
The driving force behind the deal was then-Audi boss Markus Duesmann. At the beginning of September, Duesmann was replaced by Gernot Doellner.
An Audi spokeswoman said the Formula One entry had been agreed by the company's management and supervisory boards as well as its parent company, and that the timetable remained unchanged.
There was no immediate comment from Sauber but speculation about Audi's commitment to Formula One has been swirling in the paddock for weeks.
