2011 Porsche GT3 RSR

The end of the motorsport season is here and Porsche has gone out with a bang as they have introduced their 2011 GT3 RSR at the “Night of Champions” party held at the R&D Center in Weissach. The GT3 RSR will join the911 GT3 R and the911 GT3 Cup in competing in the 2011 GT racing. Teams interested can be had for 410,000 Euro ($543,000 at current rates) plus country-specific value added tax.

The new GT3 RSR is powered a 4.0-liter, six-cylinder boxer engine mated to a six-speed gearbox. This combination delivers 455 HP at 7,800 rpm and a max 450Nm of torque. That’s five horsepower more than the GT3 Cup, but 25 less than the GT3 R. The power increase was possible thanks to an engine management system, a redesigned exhaust system, and a modified air intake housing. Stopping power comes from single-piece six-piston aluminum fixed calipers in the front and single-piece four-piston aluminum fixed calipers in the rear. Taking that power to the pavement will be three-piece BBS light-alloy wheels, 12J x 18 ET 34 in the front and 13J x 18 ET 12.5 at the rear.

The Porsche GT3 RSR has a monocoque body (basis GT3 RS) of hot-galvanised steel and receives a new front lip, wider front wheels, a modified rear wing, and a redesigned rear lid for optimized air ducting. Taking its cue from the 911 GT3 Cup and the GT3 R, the RSR has been LED rear lights taken from the latest 911 road-legal cars.

Press release

The Porsche 911 GT3 RSR takes off into the new motorsport season with extensive modifications. The 2011 version of the world’s most successful GT race car celebrated its international premiere at the “Night of Champions” party held at the R&D Centre in Weissach to mark the end of the motorsport season. Priority in the further development of the GT3 RSR was given to the newly designed aerodynamics at the front and rear, changes to the suspension kinematics and to the engine.

The 4.0-litre, six-cylinder boxer engine now delivers 455 hp (355 kW) at 7,800 revs, five horsepower more than its predecessor. The power increase results from an engine management system which adapts even better to different fuel grades, as well as a redesigned exhaust system and a modified air intake housing. Moreover, the driveability of the famously efficient engine has undergone further improvements. Maximum revs remain unchanged at 9,400 rpm.

Clearly visible are the modifications to the front. A new front lip provides higher downforce at the front axle. The front wheels are now wider with the rims growing from 11 to 12 inches giving additional grip and less of an understeering tendency. The position of the rear wing and the shape of the wing mounting also underwent optimisation and were adapted to the new rear fairing with additional air outlet louvers. The rear lid was also redesigned for optimised air ducting. Like the 911 GT3 Cup and the GT3 R, the RSR has now been equipped with the LED rear lights taken from the latest 911 road-legal cars.

The 911 GT3 RSR joins the 911 GT3 R and the 911 GT3 Cup as the top model of Porsche Motorsport’s product range. The successful long distance racer from Weissach can be ordered now at a price of 410,000 Euro plus country-specific value added tax. All 2011 modifications are available as a kit for GT3 RSR cars from the 2010 season.

This GT3 looks like their 911 model, but in spite that the aggressiveness of these two cars is very different! smiley Anyway, I’m so impressed with its powerful engine output, which can really give a nice speed on it.

The exterior design of this GT3 of Porsche is definitely looking great on it and I’m glad that they use an impressive and striking engine for this race car of them.

It is absolutely looks so striking and awesome on that design, and its engine and horsepower is kind of impressive, but I don’t think that it is not enough to have a better performance to beat its competitor.

I like the design of this race car and the rims also great. The pricing of this car is so crazy.

Now that’s what you call “ the beast”! Please do understand that Porsche have made upgrade on their production before the new season starts.

wonder if I’ll see one on the road with some stuck-up jerk behind the wheel, ruining this track car What are they 335/17’s?

That car has one hell of an 80s vibe. Not sure if it’s the yellow headlights or the body kit.

Very nice! And Stunning as always. How will this fare against the Italia?

Oh does anybody knows that website, where it shows every single Porsche 911 GT3 RSR, and Cup cars chassis were sold. Also it shows what team brought a car, and how many years they race it. It keeps track of all of today’s Porsche racing cars

There’s something to be said for real race-tested technology, and it’s why they are basically bulletproof unless you are putting stupid power levels through them that they weren’t designed for.

The engine design (the architecture at least) is still used in the current GT3/RS and GT2RS. It’s a shame they switched the Turbo over to the DFI, because this engine is legendary in the Porsche world. It’s awesome that the design has lasted 21 years and counting.

nice it looks very interesting to test drive. i think this is the perfection version of the GT3 RS.

I envy a lot of things about the newer Turbos, but I’m really glad I have the GT1-derived engine in mine. There’s something to be said for real race-tested technology, and it’s why they are basically bulletproof unless you are putting stupid power levels through them that they weren’t designed for.

Kind of pricey but if you want special attention you gotta pay for it!

Dudes, how you can expect to improve performance if you have 1200kg car. You should start building cars under 800kg to have that sweet engine pull the car easier.

looks more and more like a beast! How long Porsch developed this car until now? It has to be the best motorsportscar ever!

Impressive.. it looks kinda fun to drive.. are they also offering this kind of design? honestly I love it. the car looks sportier and aggressive with those pain jobs.
