Based on the BMW M5 (E60), the Hurricane GS features an SK II package with an LPG conversion, two ASA superchargers, a water-cooled intercooler, and a remapped ECU. As a result the M5 produces 660bhp and 650 Nm of torque. 0-62mph comes in 4.6 seconds, while the top speed is 207mph (333km/h), making it the fastest LPG powered car in the world.
G-Power says that the LPG is about 50% less expensive per litre than petrol, which is all good, until they mention that the package costs €33,571.43 (27,905 GBP) – excluding installation. When you spend all that money your CO2 emissions will be cut by roughly 15%, so in addition to more power you are also doing a small favor the environment.
The G-POWER SK II bi-supercharger system including conversion to LPG is also available for the current M6.
