The new Porsche 911 GT3 R rennsport, in technical jargon, enhances a number of the important characteristics of its donor car, including aerodynamics and the power produced by its 4.2-litre flat-six combustion engine.

In everyday language, this is off the scale. Even Porsche, which has a reputation for understating things that can be more accurately assessed using the aforementioned key parameters, calls this nutcase "probably the hottest track tool Porsche has ever made available as a collectors' item."

Undoubtedly, it is a collectible. A R19 million toy for 77 of Porsche's luckiest and most knowledgeable clients. Although we'll get to the actual figures in a second, what they get for their money is history as well.

The rennsport, which is built on the already potent 911 GT3 R, is reportedly the 'natural' replacement for the GT2 RS-based 935 from a few years ago. Every every body piece on the limited edition has been altered from a completely standard GT3 R, with the exception of the bonnet and top.

A new nose has emerged. air ducts and intakes were adjusted. an arm cowl. modified wheel arches. electronic wing mirrors. And a big rear wing, which is where the 'history' part comes in; it allegedly pays homage to the Porsche 935/77 Brumos that competed in the 1978 Daytona 24 Hours. Around the back, there are rumors of the Porsche 962 Le Mans racer as well.

Under an LED light bar is a bigger rear apron that is devoid of grille covers and paneling (to reduce weight). The 18-inch BBS "racing" wheels, which fit the correct competition regulations and look spectacular, are housed in the flared arches.

Since this automobile isn't in a competition, the engine has been derestricted, to speak of. The 4.2-liter boxer cranks out 612bhp, up from the GT3 R's 557bhp, and revs up to 9,400rpm thanks to its independence from the Balance of Performance regulations that its sister is subject to. It has custom-made pistons and cams and can operate on E25 fuels, which are supposed to enable more sophisticated ignition angles and higher compression levels.

A six-speed "constant-mesh" transmission brought over from the GT3 R but modified, resulting in sixth gear allowing the car a bit more flat-out speed, sends those 612 horsepower backwards (and perhaps maybe sideways). There is a racing exhaust that isn't muffled that makes loud noise and is described as having a "extremely emotional engine sound." 

Porsche also kindly reminds us that the chassis is a complete carryover from the GT3 R, which includes KW shocks with five-way adjustability throughout, double wishbone/multi-link suspensions up front and back, AP brakes, and specially designed Michelin Pilot Sport M S9 tires.

It has a driver's display, central dashboard panel, ambient lighting, and a "particularly rigid roll cage design" and is a single-seater, of course. The complete car idea only weights 1,240kg in total. Naturally, a variety of unique, unusual body colors and designs are available.

Which you would anticipate given its asking price of R19 million — not including tax or any other options. The new Porsche 911 GT3 R rennsport, however, "offers the experience of driving a nine-eleven-based racing car in what is probably the most primal form," according to Porsche's motorsport vice president Thomas Laudenbach.

He continues, using language that we can all understand, "It gives you goosebumps every time you look at it."
