German luxury carmaker BMW unveiled the world’s fastest hydrogen-powered car at the Paris auto show on Wednesday, dubbed the H2R, capable of exceeding 300 kilometers (185 miles) per hour.

“Our drive toward the future is called hydrogen,” BMW management board member Burkhard Goeschel said before the tarp slowly slipped off the teardrop-shaped body of the sleek race car.

Goeschel, responsible for technology and development at BMW, said the streamlined rocket car sprints from 0 to 100 kmh in about six seconds and reached a top speed of 302.4 kmh on BMW’s test track at Miramas, France.

“It’s called the H2R — ‘R’ as in record,” Goeschel said, visibly proud of the company’s breakthrough achievement in the field of zero emissions.

Unlike most hydrogen-powered vehicles, the H2R doesn’t operate on a fuel cell but rather uses a modified 6-litre, 12-cylinder combustion engine for its propulsion that essentially emits nothing but steam.

An advantage of the higher combustion pressure of the hydrogen-air mixture is its higher degree of efficiency, BMW added.

The company cautioned, however, that while the cars don’t pollute, production of hydrogen as a fuel does entail pollution.
