World's fastest LPG car

Welcome to the world's fastest LPG-powered car... the short-term future of performance cars, given the meteoric rise in petrol prices of late? Just maybe...
Based on the V10 BMW M5, this twin supercharged and gas-powered "G-POWER HURRICANE GS" will knock on the door of 206mph (333km/h) and produces 660bhp (+ 153bhp over standard M5) and 650Nm (+130 Nm), offering 0-60mph from the two tonne saloon in just 4.6s and 0-124mph in 11.4s. Hicarumba! The conversion on a V10 BMW M5 costs 33,571 Euros, excluding installation, so it isn't cheap, but it is 25% more powerful than standard, with practically identical miles per gallon figures and a 15% reduction in CO2 emissions. See www.g-power.com for more details of this impressive package...
