All new Jaguar Land Rover cars will offer an electric power train from 2020, Britain’s biggest car maker said as it ­became the latest manufacturer to embrace the electric vehicle revolution.

The company last year unveiled the I-Pace, its first electric car, and Ralf Speth, the chief executive, used a technology event on Thursday to underline the Coventry-based firm’s commitment to electric vehicles. “Every new JLR model line will be electrified from 2020, giving our customers even more choice,” Mr Speth said.

“We will introduce a portfolio of electrified products across our model range, embracing fully electric, plug-in hybrid and mild hybrid vehicles.”

The Government has said it will ban the sale of all new petrol and diesel powered cars by 2040, pushing car companies to look at greener alternative forms of power, though hybrid cars with both internal combustion and electric systems are expected to still be permitted.
