Steve, the Fusion is larger, wider and shorter than the Camry by 2mm, the Accord is larger than the Fusion by 134 mm, wider by 33 mm and taller by 23 mm. So, by your own math, the Camry competes with the Fusion, but not with the Accord... ??
Camry, Accord, Fusion, Sonata and Malibu are mid sizers, Avalon, Taurus and Azera are full sizers.
How can you say the Taurus is in the same category of the Accord, if the current Taurus is almost 200 mm larger than the Accord...?
