All new Jaguar Land Rover cars will be available in an electric or hybrid version from 2020, Britain's biggest carmaker said today, as it speeds up plans to electrify its model range. 

Last year the company, owned by India's Tata Motors, said it would offer greener versions of half of its new line-up by 2020, but it has now ramped up its plans. 

Demand for electric models continues to rise sharply.

In July Britain said it would ban the sale of new petrol and diesel cars from 2040 to cut pollution, replicating plans by France and cities such as Madrid, Mexico City and Athens. 

Carmakers are racing to tap into growing demand for low-emissions models with Nissan launching a revamped version of its Leaf electric vehicle in a bid to better take on Tesla's Model 3. 

Jaguar Land Rover, which showcased its first electric model in 2016, said it would release a range of powertrain options over the coming years. 

"We will introduce a portfolio of electrified products across our model range, embracing fully electric, plug-in hybrid and mild hybrid vehicles," chief executive Ralf Speth said. 

The car maker, which built nearly 550,000 of Britain's 1.7 million cars last year, has said it wants to build electric models in its home market.

But a number of factors need to be in place first, including support from government and academia. 

It will build its first electric model, the I-PACE, in Austria. 

Like much of the British car industry, JLR is also worried that Brexit could leave its car exports facing lengthy customs delays and tariffs of up to 10%, risking the viability of production in Britain. 

But its CEO said today he was hopeful that exporters in Britain will be able to trade in Europe after Brexit without bureaucracy and red tape because politicians on both sides will want to do the best for their countries. 

"I'm absolutely convinced that the politicians on both sides are interested to do the best for the society," Mr Speth said. 

"So therefore I'm quite clear and hope that we get free and fair trade also in the future, without bureaucracy, without red tape so that the export industry can grow again," he added.
