One of our alert readers was driving down Woodward Avenue in suburban Detroit when he spotted a prototype and quickly snapped off a few photos. That's where the mystery starts. We're honestly not sure what this sedan is.
Being in Michigan, it almost certainly belongs to either the Detroit three, Toyota, Nissan or Hyundai, all of whom have technical centers in the area. From the front view, an elliptical badge area is visible which points to Ford, Toyota or Hyundai. Judging by its footprint, it's clearly a mid-size to large car and the shape of the mirrors is consistent with the new Sonata.
So based on these few clues, we're going to climb out on the proverbial limb and predict that this is most likely either a next generation Hyundai Azera or even the new Camry. Posit your own guesses below?
