A friend at work drives a 2012 Camry Hybrid and isn't too pleased with the fuel economy she gets.
I used to get better figures than she did with my Mazda.
I stopped telling her after a while because she was getting upset.
She complained about the relatively poor fuel economy to the dealer and was told that the 2012 models weren't nearly as good as the 2013 in that regard. Not much help.
I showed her the (non-hybrid) Camry speed verses consumption chart that was posted here as a gentle hint that she may have been as much at fault as the car was.
