Before the Porsche 918 Spyder was the mind-bogglingly quick car in the lineup, there was the Porsche 911 Turbo. But even before the 991, 997 and 996 became relatively civilized performance cars, the Turbo was a lunatic and proud of it.

XCAR has taken the time to review the Turbo S and it's still a bit of a crazy car. Sure, the looks are still rather restrained compared to the older cars, but there's plenty to differentiate it from the everyday 991s. And, yes, then there's the comical speed of the thing, which in S form is 560 horses.

But I think a bigger spoiler or a checkerboard pattern to the upholstery would really liven things up.
