Stuttgart. The development of the Porsche 911 GT3 R Hybrid 2.0 is running at full revs.

This Saturday, April 30th, the further-developed version of the innovative Hybrid race car contests round two of the Nürburgring Long Distance Championship (VLN).

Another test under race conditions is planned at the fourth VLN round on 28 May.

and Patrick Long (USA) share driving duties in the orange and white ‘race lab’.

At the second race meeting in late May, Holzer and Long join forces with Richard Lietz (Austria) to pilot the Hybrid-911.

24h Nürburgring, Nürburgring 24 hour race

Porsche takes up the Nürburgring 24 hour race on 25 June with a further developed version of the Porsche 911 GT3 R Hybrid.

So, what’s been done with this latest Porsche 911 Hybrid race car?

Priority of the development was given to the improvement of efficiency through the targeted optimisation of hybrid components, which also resulted in a 20 percent weight reduction. Version 2.0 of the 911 GT3 R Hybrid is intended to achieve the same lap times as its predecessor but with less fuel consumption.

The general layout of the hybrid was adopted from the 2010 model. A portal axle with two electric motors drives the front wheels and supplements the four-litre, depending on the balance of performance classification approximately 470 hp, six-cylinder boxer engine at the rear. The output of both electric motors has increased from 60 to 75 kilowatts each. For seconds at a time, pilots now have almost an additional 200 hp at their disposal with the 911 GT3 R Hybrid 2.0.

Depending on the programming, this power is automatically activated through use of the throttle pedal. Moreover, pilots can manually call up this extra power, for instance when overtaking.

The electric flywheel accumulator, with its rotor spinning up to 40,000 rpm and stor-ing energy mechanically as rotational energy, is now housed with the other hybrid components in a carbon fibre safety cell on the passenger’s side.
At first glance, the new GT3 R Hybrid is clearly distinguishable from the 2010 model. Thanks to the optimisation of the hybrid system’s high voltage components, the large louvres in front of the rear fenders were no longer necessary. This reduces drag and also lowers fuel consumption. All in all, the weight of the vehicle decreased from 1,350 to 1,300 kilograms.

“We’ve collected a great deal of information from our races on the Nürburgring, at the ALMS race at Road Atlanta in the USA, as well as from the ILMC race on China’s Zhuhai circuit, which was an invaluable help for the further development of our racing laboratory,” says Hartmut Kristen, head of Porsche motorsport.

“The emphasis of our work was on improving efficiency. That means we want to keep the lap times consis-tent with 2010 but use less energy, hence less fuel. In this way, we support future developments of road-going, sporting hybrid vehicles.”

The cockpit of the 911 GT3 R Hybrid has also been completely revised. Most of the displays and controls have moved to the steering wheel. Drivers can operate the rest of the functions via backlit buttons now situated on the centre console.

Priority was placed on the ergonomics and the clear layout for pilots – particularly in darkness.

The new 911 GT3 R Hybrid is a perfect example of the ‘Porsche Intelligent Performance’ philosophy, a principle found in every Porsche: More power on less fuel, more efficiency and lower CO2 emissions – on the race track and on the road.

Help Save The Nürburgring! Initiative to Save the Nordschleife

SAVE THE RING! – to preserve Nordschleife for Motorsport use
In 1927 one of the worlds greatest race tracks was opened to the public after two years of construction. The track created legends.

See Sabine’s Season’s Greetings and support Save The Ring!

Germany’s Nürburgring is the world’s automotive playground. A public park for gearheads. Sadly, it’s been handed over to privateers who’ve put the entire ‘Ring at risk. Michael Frison of 20832.com explains why we need to save the Nürburgring! —Ed. Blog: www.mikefrison.com (Mike’s Profile: www.facebook.com/renn.tv)

You might be surprised by reading this headline and I’m aware the subject has not gained much awareness abroad, but there’s currently a serious threat to the Nürburgring.

Since it’s opening in 1927, the Nurburgring has been under complete public ownership and administration, but in May of this year the complete Nurburgring race track and park was rented out to two privateers (Kai Richter, Jörg Lindner). They have no motorsports background whatsoever, but are the driving forces behind the makeover, which includes the addition of a theme park with a new roller coaster that doesn’t work, more hotel capacity than the area needs, a 3,000-seat event arena, and a shopping mall. Everything appears to be far too big and remains empty most of the time.



They promised private financing, but this soon turned out to be a fake. The Minister of Finance had to resign as a consequence. Despite lack of funding completion of the project continued.

(NOTE: Video is in German, if you go to the video on Youtube , check the recent comments. You will find English)

 The heavy burden now sitting on Nordschleife’s shoulder is the debt of approximately 400 Million Euros, which seems completely unnecessary considering complete race tracks have been constructed for a fraction of this amount.

The issue is complex and has kept fans of the ‘Ring busy, but I want to share with you what just happend last week: Nürburgring officials always claim a total of two million visitors per year, but in true Wikileaks style we got ahold of an older internal document (PDF) telling a different story. Promoters always engage in number polishing, but this is of different quality. It appears there’s double bookkeeping for real vs. published visitors for all events held at the Ring. Have a look at the graph summarizing the figures:




Who would dare to claim two million spectators while only 370,000 actually turned up? The Nürburgring did and they based the business plan of the new leisure park on these numbers.

You don’t believe me? Ask Sabine next time you meet her. Several investigations have already been triggered by the Department of Public Prosecution, a governmental board of inquiry and the competition department of the European Commission.

And anyone who criticizes the current direction of the ‘Ring is answered with force. Wilhelm Hahne — the oldest of the racing Hahne brothers (his brother Armin finished 6th last weekend at the track) — had his house searched in June of last year and as recent as last week received again a warning letter from the Nürburgring lawyers for speaking the truth.

It really hurts to get sucked into politics and to witness how they treat the heritage we all love. The worst that could happen is enthusiasts be forced to pay the price of a privateer’s blunder in the form of higher prices or worse.

Please spread the word if you care about Nordschleife and its heritage. Follow ringumbau.de (the documentary community site accompanying the development) and question the information shared by officials.

Michael Frison founded the 20832.com Nurburgring site 10 years ago (ever seen the red-and-white-N logo when at the ‘Ring?). He’s also the person behind the renn.tv movies (you have probably seen Hans Stuck / BMW M3 GTR / Nordschleife Onboard), and donated the engine/idea of the Gixxerkart. He wears a Che Geuvara T-Shirt when he drives the ‘Ring.

Porsche presents GT3-RSR Spec 2011 - GT racer

Porsche is now unveiling the 2011 911 GT3 RSR, the latest iteration of what’s surely the most successful GT race car of all time.

What's new? More power, for one thing.

Porsche has made extensive changes to the 911 GT3 RSR to be competitive in the coming season on the routes of the world.

Her world premiere of the 2011er version of the world's most successful racing car in the GT racing season party "Night of Champions" at the Development Centre Weissach.   When developing the GT3 RSR had a redesigned aerodynamics at the front and rear, changes to the suspension kinematics and on the engine in the foreground.

The Porsche 911 GT3 RSR, including lots of detailed improvements in the new season.

The naturally aspirated 4.0-liter flat-six gets a 5-hp bump to 455, the full power of which is unleashed at 7800 rpm. Maximum torque is 332 lb-ft, and the powerhouse still redlines at a screaming 9400 rpm. Vrroooom!!!

To achieve the slight power gain, Weissach engineers tweaked the engine control to adjust even more precisely to differing fuel quality. The intake is also reworked, while the exhaust system is entirely new. The four-valve-per-cylinder engine sports individual throttle bodies and dry-sump lubrication. It’s an evolution of a tried-and-true engine, not the new, direct-injection powerplant now used in most of Porsche's street-legal 911s.

The task of routing the power to the rear wheels falls to a sequential six-speed gearbox with a three-disc carbon clutch. The traction-control system is adjustable and tuned to enable maximum acceleration. Eighteen-inch BBS wheels are fitted; the fronts are wider than last year’s—12 inches instead of 11—while the rear wheels remain a staggering 13 inches wide. The suspension is completely adjustable. Despite a galvanized-steel body, the new long-distance racer weighs a claimed 2690 pounds.

From the outside, you can tell it's the 2011 model by the LED taillights taken directly from the street-legal current-gen 997. There is a new front lip spoiler with improved airflow; the rear is also tweaked, adding additional apertures for ventilation. While the rear now looks much like the current 997, the GT3 RSR curiously keeps the looks of the “phase-one,” pre-2009 997 at the front. The cutout for the front turn signals looks almost exactly like that of the 2004–2008 models. It's a surprising decision as the GT3 Cup and the GT3 R, the RSR's sister models in Porsche Motorsport's lineup, showcase the latest 911 styling in full.

The 911 GT3 RSR is not street legal, and the price is steep: In Germany, Porsche will charge €410,000 before taxes. At current exchange rates, that’s more than half a million dollars. But for those on a budget, Porsche Motorsport will offer a kit to upgrade last year’s model to 2011 specs.
