Porsche 911 GT3 R - New Racing Version for International GT Sport

Porsche 911 GT3 R

More power, added refinement

Porsche has unveiled the successor to the 911 GT3 Cup S, the 911 GT3 R.

Designed to meet international FIA GT3 regulations, the GT3 R features a 4.0-liter six-cylinder boxer engine with 480 bhp (353 kW). Connected to a six-speed sequential ‘dog' gearbox, power flows to the rear wheels without interruption.

According to Porsche, engineers worked tirelessly to give the GT3 R better drivability and easier handling than the GT3 Cup S. In order to do this, they cut the car's weight to 1,200 kg (2,646 lbs) and increased the engine size by 0.2 liters (which adds 30 bhp). The company also improved the anti-lock brakes (ABS), revised the traction control system, and added an ‘e-gas' function with throttle-blipping.

Besides the performance tweaks, Porsche updated the exterior with wider wheel arches, a revised front end, and LED taillights.

Priced at €279,000 (plus local sales tax/VAT), the 911 GT3 R will go on sale in spring 2010.

Porsche 911 GT3 R

New Racing Version for International GT Sport

Stuttgart. Following the Porsche 911 GT3 Cup, Dr. Ing. h.c. F. Porsche AG, Stuttgart, is entering yet another racing car in the 2010 motorsport season: The 911 GT3 R will be raced in series based on the international FIA GT3 regulations, thus succeeding the 911 GT3 Cup S. The main focus in developing this new model was on even better drivability and even easier handling.

The 911 GT3 R is powered by a four-litre six-cylinder boxer engine delivering maximum output of 480 bhp (353 kW) transmitted to the rear axle by a sequential six-speed dog gearbox.

The starting point in developing the 911 GT3 R weighing just 1,200 kg or 2,646 lb was the Porsche 911 GT3 Cup presented in September for one-make cup racing. Thanks to its increase in engine size by 0.2 litres, the GT3 R offers 30 bhp more than the Cup model. Both cars are based on the extra-wide body of the 911 GT3 RS street-legal sports car.

An anti-lock brake system (ABS), traction control and an e-gas with "throttle-blip" function make it much easier to get used to this new GT3 racing car than its predecessor, meaning that the new model is also more appropriate for the ambitious amateur racing driver.

Flared wheel arches added on to the body both front and rear bear clear testimony to the wider track than on the former model. And like all second-generation versions of the 911, the new 911 GT3 R also comes with striking LED rear light clusters.

The Porsche 911 GT3 R is making its world debut on 14 January 2010 at the Birmingham Motor Show. The car is built by Porsche's Motorsport Department at the Weissach Development Centre and will be delivered to Customer Teams the world over as of spring 2010. The base price of the Porsche 911 GT3 R is 279,000 euros plus local sales tax/VAT.

What happened to the 911 RSR? It would be nice to see 911 GT1 again :D

usually they release the RSR after the winter testing. i'm curious to see what they come up with this time. i'm sure they power will be the same or just a bit more then the R's but it will be lighter. the GT2 championships will be very interesting next season.

A dog gearbox isnt like a regular gearbox in your focus, minivan etc. Difference is that a dog gearbox has a straight cut set of gears-and comes with a LOT of noise. ill quote from wiki:"A dog leg gearbox is an unusual manual transmission layout, an up-over-up shift between first and second gear resembling the hind leg of a dog." only usually found with truck transmissions, but take a look at wiki and you'll see some other cars that had it

like he said. a dog gear is a straight cut gear as opposed to a helical gear found in normal transmissions. dog gears are used for racing applications because there is less contact area between the teeth which results in lower loss of power due to friction. On a side note: I want this car!

"Connected to a six-speed sequential ?dog' gearbox, power flows to the rear wheels without interruption." The keyword here is "sequential," not "dog." It's basically like a motorcycle gearbox in that in order to go from 1st to top gear you must first shift through all the gears in the middle. In other words, it is mechanically impossible to skip gears. Ever watch a WRC race? The driver pulls back (or pushes forward) for every gear change, there is no "up-over-up" canine appendage-like shifting pattern because the sequential box does not use the "H" pattern found in 50yr old dump trucks or your brother's BMW. In sequential gearboxes all gears are meshing at all times, the "dogs" are simply the mechanisms that engage the gears. When a gear is engaged it goes from being a gear that is simply going along for the ride to one that is locked to the shaft and transmitting power. The transmission gears themselves can be either straight-cut (for really cool noise, less friction, and possibly for ease of service which is handy in a race) or helical, i.e. angled cut, for quiet operation and increased strength due to increased gear surface contace area. If that wasn't confusing enough you should know that even the regular manual transmission in your personal car has mechanisms called "dog collars," "dog clutches," or "dog rings" which essentialy serve the same purpose.

Interesting explanation EDavis. Thanx.

The main feature of "dog" gearboxes is that they don't have synchronizer rings, but use a totally different layout with square-shaped teeth to "lock" the free-spinning gear to the output shaft of the gearbox during gearchanges. This layout makes more noise and requires greater force to engage the gears, but is much more durable.

I wish this car was made for the street, it would be a completely badass car for the street, sans suspension, wheels (someone may jack them), and the noise of the dog gearbox as so i heard from a friend of mine who has it in his car, but only for drag races though.

Good to see Porsche is still building things like this even in their financial situation. NICE!

The already godbly GT3 family gets even better with this new addition. I wonder if Flying Lizard will make the switch, they're usually up to date on switches due to intense competition. Amazing performance aside, this is one of the best looking Porsches ever period.
