Toyota Motor Corp. is set to unveil a fuel cell concept car that aims to offer 50 percent more driving range than its current hydrogen-powered sedan in a technology push that defies a rising wave of battery-powered vehicles.

The nation's biggest auto manufacturer is targeting a 1,000-km (620-mile) range for the Fine-Comfort Ride concept saloon under local standards, compared with about 650 km for the current Mirai fuel cell vehicle, according to a statement Wednesday. The concept car, to be introduced at the Tokyo Motor Show next week, will include artificial intelligence and automated driving features.

Toyota is continuing to champion fuel cell vehicles as the ultimate zero-emission cars, even as the falling cost of lithium-ion batteries have lured a majority of automakers to plug-in technology in the face of ever more stringent environmental standards worldwide. China, the world's largest market, said last month that it was working on a timeline to end the sale of internal-combustion vehicles, joining countries including France, India and the U.K.
