A premiere tuning company located in Russia called TopCar has delivered some sketches and renderings of their newest Porsche Panamera tuner vehicle. Porsche Panamera tuning is nothing new, and it's no mystery that there's a lot of aggression and fury underneath it's beautify skin.

The 2011 Panamera Stingray GTR is still a concept, but from what TopCar has produced so far (they already have a Panamera Stingray tuner) it appears as if they've pushed the envelope just a bit more. This GTR version will be based off the Panamera Turbo platform and is slated to boast a 600-hp powerhouse. Yowzah. The GTR will also come with a fully revamped body kit and a quad exhaust that I'm sure will sound as ridiculous as it looks.
