Going green has perhaps never looked better as Bernie Towns teams up with Speedriven to produce this CNG-Powered Mercedes-Benz SL 600. Not only is the car nicely built in the aesthetics department, it packs around 800-whp and over 1,000 ft-lbs of torque out of its 5.5L twin-turbo V12 powerplant. This helps it get down the quarter mile in merely 10 seconds, but Speedriven and Towns has more plans.
Their current goal is to claim the title of world’s fastest CNG-powered car, which currently belongs to Hohenester’s Audi A4. The A4 was able to hit 226.55-mph back in 2009, and Speedriven is hoping with some more tweaks to the aerodynamics they are hoping it’ll support speeds in excess of 240-mph.
Plans to achieve more power includes fitting on a new turbocharger system and completing the natural gas conversion. Their intention is to break the speed record when it debuts in March at the Texas Mile event.
