Top global brands will be fighting it out to electrify buyers at China's premier car show opening tomorrow in Beijing.
The country is already the world's largest auto market and took the number one spot for electric models last year, with some 247,000 "zero emission" cars sold -- quadruple the number in 2014 -- according to the China Association of Automobile Manufacturers.
So far only around one percent of cars owned in China are electric, but authorities are pushing them as a potential solution to the country's crippling air pollution health crisis.
While electric cars are becoming more popular worldwide, particularly high-end brands like Tesla, their hefty price tags and restricted driving range mean they are still only a niche market.
Their evolution has been mainly state-subsidised, as in Norway, which has the world's highest penetration at 17 percent of new sales in 2015.
But experts say winning even a small chunk of Chinese sales -- which totalled 24.6 million last year -- could be a game-changer for electric cars.
Jean-Francois Belorgey, an expert with consultancy EY, predicted that by 2020, up to 750,000 electric cars will be sold in China every year.
"China is perhaps the one place in the world where the automobile industry can achieve the economy of scale needed to bring down costs," he said.
