Porsche Panamera Stingray GTR

BENCHMARK!

Not satisfied with Porsche's standard Panamera offerings? Take things one step further and order up a Porsche Panamera Stingray GTR ($TBA). Aggressively modified by Russian outfit TopCar, this limited edition — only 25 are being made — sports sedan features a nearly all-new carbon fiber and Kevlar body, including new front and rear bumpers, air vents, front and rear fender extenders, front and rear doors — the latter of which open with the press of a button — bonnet, wings, rear diffuser, spoiler, and side skirts, along with performance enhancements like a sport air filter, intake manifold, and valved exhaust system that boost horsepower north of the 600 mark.
