Because cars like the Porsche 911 GT3 RS are so good, it becomes harder for tuning companies to genuinely improve on something that automotive journalists frequently describe with superlatives.

Vorsteiner playfully named this car the 'Purple Beast', which not only fits because the car is purple, but also because it represents everything that Porsche is about when making supercars - ultimate track performance machinery.

Powered by a 4.0-liter flat-six, this 911 is packing around 500 PS to go with its 460 Nm (338 lb-ft) of torque, which boosts its chances of reaching 100 km/h (62 mph) in just 3.3 seconds before maxing out at 310 km/h (192 mph).

Though not as quick as a Turbo S in a straight line, the GT3 RS will more than make up for it on the track, which is where this type of vehicle belongs.
