Ginny Buckley, the chief executive of Electrifying.com, the electric car buying and advice site, said brands should invest in electric cars to match market trends.
She told GB News: "Whichever way you look at it, diesel's on the way down and electric's on the way up.
"Vauxhall, Peugeot and Citroen are in danger of missing the boat twice if they don't invest in making the efficient, practical, affordable EVs that their rivals already have on sale."
