The G-Power name has become synonymous with extreme BMWs and the company’s latest Hurricane GS based on the M5 sedan fits in perfectly with that description.

You may have read about G-Power’s past creations at our sister site MotorAuthority; such cars as the BMW M5 Hurricane RR, the world’s fastest four-door, or the BMW M6 Hurricane RR, which possesses the title of world’s fastest four-seater coupe.

Now the German tuner has built what it’s billing as the world’s fastest natural gas powered car, the BMW M5 Hurricane GS. The car runs on liquefied petroleum gas (LPG), in some forms referred to as propane or butane, and it features a 5.0-liter V-10 that has a pair of superchargers attached.

Peak output is 660 horsepower and 480 pound-feet of torque, which is enough to rocket it from 0-62 mph in just 4.6 seconds and see it reach a top speed of 206 mph--1 mph more than a Corvette ZR-1 supercar.

With LPG costing half as much as gasoline in many parts of the globe it’s easy to see how beneficial this system could potentially be. Other benefits of LPG are that it emits around 15 percent fewer CO2 emissions than regular gasoline and has a higher octane rating too.  

There are some downsides, however. LPG doesn't have the same calorific (energy) value of gasoline, which means mileage is usually worse. LPG can also be difficult to find as many fuel stations don’t serve it.
