A powerful and responsive, 5.5-liter twin-turbocharged V12 engine is not usually what comes to mind when you think of “green” cars, but – if Bernie Towns and the crew at Speedriven get their way – it soon may be.
Bernie Towns is an engineer at HighMount Exploration and Production – a natural-gas-focused energy company based out of Houston, Texas. “Clean” and “green” are everyday buzzwords in the energy-production industry, and Towns’ company Future Power Technology well be no exception, promoting research into new ways to push CNG into the mainstream. In addition to being well-versed in current green-energy trends, however, there is something about Bernie Towns that is different from the usual green-car advocates. “I admit it. I’m a horsepower addict,” Bernie says. “I love speed, I love power, and I love my Mercedes-Benz.”
The object of Towns’ current automotive affections is a 2007 SL600 Mercedes-Benz roadster, which – after nearly a year of research and development work by Chicago-based tuning firm Speedriven – now develops over 800 horsepower and over one-thousand pound-feet of torque from its biturbo V12. Good enough for 10-second quarter mile runs and a top speed well in excess of 200 mph.
Towns’ massively powerful Speedriven SL satisfied his need for speed, then, but Towns still felt that something was missing. “In the IT world, we literally spend hours of every day coming up with ways to do business in more efficient ways and (at HighMount) in more environmentally responsible ways,” explains Towns. “So there I am, sitting at lunch one day and the people are talking about natural gas cars, and it suddenly hits me: we should convert the SL to run on natural gas!”
