Seems like a plausible retrofit to a FWD daily driver city vehicle. (200 more ft# in a MINI, anyone?)
Casual googling reveals a target price of $3K for the system. At $4.50 a gallon for premium in LA, that's equivalent to ~700 gallons of gas, or 40 tankfulls, or a year of driving. Conclusion: it pays foritself in savings over two years, if it really does double your mileage as per the claim. Plus you get the tax benefits and other perks - carpool lane access, etc. That's a win, if they hit the price point & performance numbers.
