Porsche Motorsport North America, Inc. has announced that production in Stuttgart, Germany has commenced on the 2014 Porsche 911 GT America, a race car based on the Porsche 911 GT3 Cup. The car is designed exclusively for the new United Sports Car Racing series GT Daytona class for 2014.

The new car will be delivered starting in October, 2013 and be offered for sale to those teams committed to running the entire 2014 USCR season.

Jens Walther, president of Porsche Motorsport North America, is pleased that the factory has been able to move so quickly to create this endurance racecar – and build it to the upcoming 2014 USCR GT Daytona rules – so teams will have adequate time to attend all the winter test sessions in advance of the season debut at the Rolex 24 at Daytona.

“We are hopeful that our current American Le Mans Series GTC customers, along with our Rolex GRAND-AM competitors and new teams, will want to take advantage of this early availability,” said Walther.

The 911 GT America features a Porsche flat-six 4.0 liter racing engine which will produce 470 hp and utilizes a six-speed sequential gearbox with pneumatic paddle shift system and electronic throttle. The car is based on the Porsche 911 GT3 Cup racer that currently exclusively runs in the Porsche Supercup series, and features lightweight bodywork with aluminum-steel composite construction, a fuel safety cell with new quick-fill connection, new color Cosworth dash display, and new safety equipment including a rescue opening in the roof allow use of the KED system for driver stabilization.

A newly developed race braking system further improves the excellent endurance qualities compared to its successful predecessor. The 380 millimetre slotted and inner-vented steel brake rotors at the front axle are decelerated by six-piston aluminium fixed callipers. The rear axle features a four-piston version.

Retailing at $269,000 (FOB Weissach, plus shipping and parts package), the new Porsche 911 GT America is sold in North America exclusively by Porsche Motorsport North America, Inc., based in Santa Ana, California, and at the following link.

The uprights for the wing look ugly... Is the wing a standart-part which is the same on all cars competing in class?

GTgears

Not wide enough...

Polesitter

This is consistent with what I posted a few days ago.

As to the wing, it is not a Porsche part. It is a spec wing mandated by USCR and made by Crawford. Unfortunately this (ugly) wing required some other massaging of the aerodynamics package and hence some of the other variances to the cup from an aero perspective.

So..... will the Metzger engine ever be replaced by the 91A in a racing car?
(I'm good with it staying)

That wing is absolutely amazing....on my WC Cayman..><G>
on a GTA2 cup, its an immediate take off swap out.

Is this car then the defacto WC car?

fleadh

Doubt it. The WC cars are closer to GT3.. the GT America is going to need more downforce to compete in WC.

probably will need new bodywork, splitter, wing , upright.

and with that, then WC would have to approve the 4 liter for WC competition. they might actually permit it , or atleast should, because frankly, with the Audis, and cadillacs and volvos, they've destroyed the GT3 Cup in wc which is a real shame since they were a good solid all purpose car in world challenge. i cant recall seeing but 1 per race, maybe 2 most. and now, at the back for the most part, with good pro drivers in them.

its time to allow the 4 liter in WC GT an this might be a great baseline car to do it with.

New engine DFI coming 2015
The 2014 cup is the same as the 2013 cup 991

That's kinda my point, looking at the picks, the splitter looks pretty much a WC splitter with floor, it has the Crawford wing, and with the 4L and paddle shift it seems like it would be up at the limits of the class without changes. Seems like porsche is trying to build a factoy variant for all series.

Porsche don't by any means own or control Grand Am though there are a lot of good grand am teams running pcars in there. I would imagine Porsche went to grand am rules chair, submitted what they were seeking. with the Ferrari and audi having flappy paddles, and undertrays and splitters, Porsche submits the request. they probably approve subject to testinga nd they'll just add/remove weight or ride height to adjust for any changes.
the pcar was fast for sure in rolex. so now going to paddle shifters, and the splitter, body work, etc. the car is going to edge higher.

that's kind of the issue with all these series..they are always getting faster and more developed, etc. they showcase modern day, current cars, and as the cars get better/faster/more developed so goes the series.

to me that was why I think the Cayman struggled in GS. it was at it max power. no one is better with the caymans than Tecce and they did everything they could to make it competitive, it just didn't have the ponies to go with the Camaro and mustang. dang 3.4L DFI motor is a great motor, just not against a 6.2L Camaro beast. tecce goes to 3.8s and has raging success. wasn't the driver, wasn't the team, simple the motor.

the good new is that for club dudes, there will probably be a couple of nice GTA2 cars coming down the pipes. you'll have to swap out some bodywork, get a new wing, toss some abs in that bad boy, but an ex-magnus rolex car would look sweet whaling around lime rock pca.

i am hoping some RSR's and GT3 R's become available when this 991 hits.

tcsracing1

so for 2014 they will offer North America both a 991 GT3 Cup and 991 GT AMERICA?

Other then aero, what would be the key differences in price and performance?

coryf

The "normal" 991 cup will be 3.8l and cost 207K The GT America will come with the 4.0l currently used in the GT class, RSR style open exhaust, endurance package (dry brake on the fuel cell, quick disconnects on the calipers, oil level gauge) New front splitter (Which Jens rumored will soon be seen in other series) An additional under tray, the RSR duck bill deck lid and the mounts for the spec crawford wing.
