这两年苦逼的雷诺汽车

Renault's problems are piling up. Now its sales are slumping

Renault has told investors to expect weaker sales in 2019, a warning that raises new concerns about the health of the French carmaker after it ousted its second CEO in less than a year.

The carmaker said in a statement late on Thursday that it expects revenue to decline by up to 4%, instead of remaining flat as previously forecast. It also cut its profit margin forecast.

Investors reacted to the warning on Friday by pushing shares in Renault down more than 14% in Paris.

Automakers have been hit by sluggish global growth and weaker sales, particularly in China. New CO2 emissions regulations in Europe, which make it more expensive to make cars, have added to their woes.

Renault has other challenges, too. The carmaker's alliance with Nissan and Mitsubishi was thrown into confusion last year when its architect, Carlos Ghosn, was arrested in Japan and later charged with financial misconduct.

A proposed takeover of Renault by Fiat Chrysler collapsed in June after Renault's biggest shareholder, the French state, dragged its feet.
