As promised, the hydrogen-powered engine used by BMW in test runs will be offered in a production car, called the 750h, before the new 7 Series is rolled out.

The announcement that it will be offered for general sale came as Berlin's first hydrogen refuelling station was opened. This forms part of Germany's Clean Energy Partnership, a countywide initiative to set up the necessary infrastructure for hydrogen refuelling.

However, the 750h will be able to run on both petrol and hydrogen.

The H2R car used in a record attempt in September was developed by BMW Forschung und Technik GmbH.

At the event, the Munich-based company said the H2R "clearly demonstrated the supremacy of BMW in developing the hydrogen engine to production standard".

It added that it "would be launching a dual-mode version of the current 7 Series during the production cycle of the present model, thus introducing the first car of its kind able to run on both hydrogen and petrol."

BMW's six-litre 12-cylinder engine used in the H2R was adapted to run on hydrogen fuel through the adjustment of its engine management as well as the fuel/air mixture formation components.

With a top speed of just under 300 km/h, it set records for the fastest flying-start kilometre and mile, fastest standing-start one-eighth mile, quarter-mile, half-kilometre and mile, standing-start 10 miles, kilometre and 10 kilometres.
