Agree, more hybrids would make this fair. If anything the non-hybrid MKZ should be here since a lot of the cars in this comparison are non-hybrids.Nice comparison list. But to be fair, except for the top two all the others cars are petrol. It would be better if we could see more hybrids in there.
Clearly Kia needs to improve on MPG, but with the Cadenza being so cheap some people may not car so much, 28MPG's isn't all that bad.
