Might some of the fault for the Sonata's poor MPG showing be that the driving was all highway? Most hybrids get better mileage in stop and go (slower) driving...At highway speeds hybrids are operating on gas engine only...negating the benefits of their electric-powered capabilities... Just a thought...Very well written, informative article...Also, the Volt, in Ontario, would cost about 37,000...Would that not bring it's savings in fuel down to a viable level over some of it's competitors here? Thanks Jack
