Every new Jaguar Land Rover (JLR) vehicle line launched from 2020 will be electric or hybrid, the company has announced.
The carmaker said that the first of the new models would be a fully electric vehicle, the Jaguar I-Pace, to go on sale in 2018.
JLR chief executive Ralf Speth said the move was aimed at “giving customers even more choice”.
The firm, Britain’s biggest carmaker, is owned by India’s Tata.
In July, Chinese-owned firm Volvo said all its new models would have an electric motor from 2019, one year earlier than Jaguar’s deadline.
However, both Volvo and JLR will still be manufacturing earlier models that have combustion engines.
“The internal combustion engine is state of the art,” Mr Speth said. “We will see this internal combustion engine, petrols and diesels, for many years to come.”
The announcement comes as the car industry seeks to show its green credentials in the wake of the Volkswagen emissions testing scandal and as governments take action aimed at limiting climate change.
“One thing is clear the future will be electric,” Mr Speth said.
“Every new Jaguar Land Rover model line will be electrified from 2020, giving our customers even more choice.”
“We will introduce a portfolio of electrified products across our model range, embracing fully electric, plug-in hybrid and mild hybrid vehicles.”
UK car industry expert Prof David Bailey, of the Aston Business School at Aston University, said the move was an important shift.
“Jaguar Land Rover have been lagging behind. They’ve been too slow to see the potential of electric cars – they’ve been focusing very much on light-weighting their cars and developing the internal combustion engine,” he said.
“They’ve fallen behind and they’re playing catch-up, so this is a significant step and it is to be welcomed.”
Jaguar said it had also engineered an electric version of the classic Jaguar E-type car, known as the E-type Zero. However, it was intended as a concept car and would not be available for sale.
JLR said it would be showing off some of its innovations to the public at a three-day Tech Fest, opening on Friday at Central Saint Martins art school in London’s King’s Cross area.
