Goldman Sachs has warned that European automakers are at risk of losing market share to Tesla and Chinese firms. The Wall Street investment bank said the transition toward battery electric vehicles in Europe could spark swings in some share prices. Europe's incumbent mass-market brands accounted for 72% of sales last year, Goldman Sachs analysts said. Chinese electric car maker Nio announced plans to open a manufacturing plant in Hungary last year. The change in regulation allowing for e-Fuel — a synthetic drop-in replacement for gasoline — also has the potential to de-risk companies and brands, according to Goldman Sachs.
