An environment friendly engineer in Texas has decided to make his Mercedes SL 600 green and clean for some odd reason. Honestly, he should just buy an electric car, but his name is Bernie Towns, and he has turned his 2007 SL600 Mercedes into a compressed natural gas (CNG) fueled sports car. He hopes that it will be able to break the record for the fastest natural gas car around. Bernie has partnered with the Chicago tuning company Speedriven, who have pushed 800 bhp and more than 1,000 ft-lbs of torque out of the Mercedes SL. Breaking the record will difficult, since the title is currently held by the Hohenester Audi A4 that was able to reach 364.6 km/h in 2009 with 700 bhp.
