European auto companies' sales volume in June will be unpredictable.

According to Bloomberg News, European car sales slowed down in June as the pressure on business and consumer confidence fell after the referendum on Britain's exit from Europe in June.

In a recent statement, the Association of European Automobile Manufacturers (ACEA), an industry association, said vehicle registrations in the European Union and the European Free Trade Association (EFTA) market last month were up 6.5% from 151,000 in the same period last year. June was the 34th consecutive month of European market sales growth, although its growth rate has been slowing since March.

In the first half of this year, sales increased by 9.1% and sales totaled 8 million 90 thousand.

Sales of Renault and Fiat-Chrysler rose last month, spurred by growth in European market demand, as did sales of other Asian brands and European luxury car manufacturers.

Among the top 10 automakers in the region, Renault grew sharply in June, boosted by sales of its major brands, Captur, Kadjar and Espace, with overall sales surging 20% year on year.

Fiat Chrysler's vehicle registration grew 13% year-on-year, mainly driven by sales of its Fiat brand, which has just launched a new Tipo compact car. Jeep sales grew 16% year-on-year, contributing a lot to Fiat Chrysler's sales drive.

Among many Japanese automakers, Toyota and Lexus sales increased by 6.7% year-on-year, while Nissan sales fell by 2.9%. Sales of modern Korea and KIA rose by 13% and 14% respectively.
