Volkswagen is considering shutting four German factories and ramping up job cuts to as many as 100,000, two people familiar with ‌the matter said on Friday, in what could be the biggest ever overhaul in the industry.Members of VW's supervisory board have been informed of the plans, which are due to be discussed at a July 9 meeting, the people said.

The move comes as the carmaker faces mounting pressure from Chinese rivals, stiff tariffs on car imports into the United States, as well as dwindling demand in Europe, which the company has said makes its business model unsustainable.

Closing the plants at Hanover, Zwickau, Emden and Audi's ​Neckarsulm site would put more than 45,000 jobs at risk, according to the people. That would add to the 50,000 cuts that are currently planned.

In absolute terms, laying off 100,000 people and ​axing four assembly plants would be the largest restructuring in automotive industry history.

It would be comparable to major shake-ups by GM leading up to and during its ⁠2009 bankruptcy and in the early 1990s when it cut as many as 74,000 jobs over four years and shut or idled 21 plants.
