Dedicated CNG EcoBosst Engine

I would love to see Ford develop an engine - especially an EcoBoost engine - designed to run solely on CNG. Because of the octane rating, optimizing an engine to run on CNG would allow much higher compression ratios which would counteract the power loss associated with converting a gasoline based engine to run on CNG. A CNG fuel specific engine would allow either improved performance or improved fuel economy. Combine that with a less expensive fuel and you have a winning combination. If Ford came out with a dedicated CNG engine in a vehicle then I would buy it, especially if it came off the EcoBoost lineup.
