With 660 hp on tap, G-Power‘s LPG-powered Hurricane runs to a top speed of 333 km/h – which (according to G-Power’s announcement) makes the M5-based Hurricane GS the fastest natural-gas-fueled vehicle you can go out and buy today.
G-Power starts with BMW’s production 500 hp 5-liter “high-rev” V10 (which burns gasoline), then adds a sequential, five-cylinder LPG injection system to each cylinder bank. To take advantage of the LPG’s improved burn characteristics compared to gasoline, the company adds a twin-scroll water-to-air intercooler and a pair of ASA T1-313 superchargers. The Hurricane puts all this newfound power to the ground through wide Michelin tires and exhales through an open exhaust system, which should sound AMAZING while still burning significantly cleaner than its petroleum-fueled production cousin.
Just a quick reminder: the overall LPG record for a production-based car is still held by a one-off Audi A4 optimized for a 364 km/h record run.
