2014 Porsche Panamera Turbo S facelift revealed

The 2014 Porsche Panamera Turbo S (pictured) debuts in Tokyo next month. It’s six months since Porsche revealed a facelift for the Panamera and now, ahead of its debut at the Tokyo Motor SHow, we get the final piece of the Panamera range’s updates – the 2014 Porsche Panamera Turbo S.

While the Cadillac XTS hasn't been a stranger on public roads around Michigan, this heavily camouflaged example is a bit of a mystery.
