Wrong! Diesel is in decline for years in Europe.
France
French diesel sales in March 2018 suffered even more than last year, dropping to a 40% record low, a 7% decline. The diesel market share hasn't been this low since 1998. The decline started in 2012, when 73% of new car registrations were for diesel cars. This year, however, the hitherto stable decline seems to be accelerating and there are no signs for that to change.
Germany
German diesel sales continued their downwards spiral, too, after a German court ruled that cities have the authority to ban diesel vehicles. For the whole German market, diesel sales fell 25%, resulting in a 31.4% share of the market. In Germany, too, petrol recovered a large part of this decline, gaining 9% to a 64% market share.
United Kingdom
Diesel sales decreased 37% to 153,59 vehicles. The market share for diesel fuel has reached a 43.5% low.
