    Re: Back OT-991 at the Ring Thread Closed

    I really doubt it as they want to drastically improve the fuel consumption on all models.

    Just my 2 cents though.


    Re: Back OT-991 at the Ring Thread Closed

    Wshful thinking on my part, i too think engines will shrink. BMW is doing it, many are doing it.

    indeed shifting is ancient technology - so is a fuel burning engine..  I happen to like both :)

    991 will be in market from october 2011...


    Re: Back OT-991 at the Ring Thread Closed

    So as MY2012. Makes sense, give the 997.2 another 1.5 years or so. Also with the GT2 RS coming out in the summer, we will have a full year of a nice complete 997.2 911 model range. thanks for the info.

    Re: Porsche 991 in testing... Thread Closed

     Zzzzz

    I know this is a pretty Porsche fan forum, but God, I am so bored of 911's. I almost wish they'd leave the camo on just so it would look different.


    Re: Porsche 991 in testing... Thread Closed

    Although I am not as bored with the 911 design as wedouglas, I relate to what he says.  These days, when I visit a dealer I look at the Panameras, Cayennes, the new Boxster GTS, the "hotter" 911s like the GT3s and turbos.  The standard 911 designs (Carrera, Carrera 2s and 4s) seem a bit too plain, out of date in some way.  Can't really put my finger on it, but "boring" could certainly be an applicable adjective for me.  It is the way I felt about the 911 series in the late 1980s, before the 993 series. 

    While saying all of this, I don't advocate a radical change with all sorts of new creases, angles and gimmickery.  I would like to see more a more racier look, with wider rear wheel wells, tasteful vents and more modern (whatever that means) spoiler treatments.  An interior with more Panamera elements, along with the expected power and performance additions, will surely help. 

    The Porsche designers have a tough job.  How to make an icon more "exciting, less boring"?  I am hopeful, however, with all the new initiatives appearing (918, GT hybrid, Cayenne, Panamera).  The 991 designers have some nice flavors to stir into the new design pot...

    Looking forward to the Porsche 991 GT3, it’s worth keeping in mind that the GT3 and GT3 RS are developed by the Porsche Motorsport team, driven by Andreas Preuninger, alongside the GT3 Cup cars. The GT3 and GT3 RS are used to homologate Porsche's GT3-based racing cars...

    Porsche-GT3-Engine-History_Article-link

    Porsche-911-Engine-History_Article-link

    The 991 GT3 is expected to include a GT1-derived engine, based on the awesome Porsche motorsport engine, originally designed by Hans Mezger.

    Here are a few comments from the interview of Andreas Preuninger with Chris Harris at the launch of the Porsche 997.2 GT3 -- which were also repeated at the GT3 RS launch event...

    ANDREAS PREUNINGER, PORSCHE MOTORSPORT PROJECT MANAGER FOR 911 GT3, 911 GT3 RS, 911 GT2 RS:

     

    Andreas Preuninger: "So, this is the motor -- like on almost every Porsche there's not so much to be seen because it's a Flat Six boxer motor and it lies pretty much hidden... but when you drive it, when you feel it, when you hear it -- that's what it can do best."

    AP: "We have a 3.8-litre here -- we enlarged the displacement by 200cc on that car, adding a lot of torque to the engine, adding a lot of bite on lower and middle revolutions... You notice the difference right from the start, because there's so much more torque available between 1500 and 4000rpms -- that's the range you use the car normally in 90% of all street-going traffic -- that's where the car has a lot more bite than its predecessor. It's a lot more torquey, you end up being one gear higher always than in the last car."

    AP: "The sound hasn't changed so much... a bit more volume in the sound -- I'm afraid it's got a little bit louder, when the exhaust flaps are open -- but I think our target group will accept that."

    AP: "We increased the diameter of the pistons, so the stroke stays the same -- we have 102.7mm of bore, instead of 100mm in the old car and that adds up, on the same stroke, to 200cc more. So we can use the same crank and we just differentiated the rods... titanium rods. Even though the the piston is a lot bigger in diameter, it weighs less than the 100mm piston on the old car -- so we even found some weight despite increasing the diameter of the piston."

    AP: "It is still the GT1-based engine with eight bearing points and seven oil suction pumps and a full dry-sump system, like in a race-car. So this is almost a race engine and it's up to any task on the race track."

    Chris Harris: So the question I have to ask is why no DFI?

    AP: "We wanted to stick with the GT1 motorsport block -- we need it for for homologation, because this is the block we race with and this is a homologation car and it needs the same block as well." 

    AP: "This car is really set up for race track use and that's why we intend to keep it for one more generation or maybe for even more, because customers love this engine... it has lots of character and the GT3 is all about emotion and character and this is what this engine can do best..."

    AP: "We are absolutely sure that performance wise and for durability, this is the best choice for a GT car..."

    A preview of the 2012 Porsche 991 GT3 / RS engine specification...

    The Porsche 991 GT3 features a four-litre six-cylinder boxer engine delivering 480 hp (353 kW). In developing the 991 GT3, the emphasis was placed on increased performance, driveability and handling. A six-speed sequential gearbox transmits the power to the rear axle.

    The development of the Porsche 991 GT3 is based on the Porsche 911 GT3 R racing car, using the extra-wide body and chassis. Thanks to a 0.2-litre increase in engine capacity, the 991 GT3 delivers 30 hp more than the previous GT3 RS model.

    Porsche 991 GT3 / RS engine specification:

    Porsche GT1-derived motorsport engine
    Six-cylinder boxer configuration, water-cooled
    3996cc naturally aspirated flat-six

    Porsche Motorsport press release: "The 911 GT3 R"

     

    Developed for racing series based on the international FIA GT3 regulations, the stunning 911 GT3 R succeeds the 911 GT3 Cup S and is delivered to customers ready-to-race. The starting point in developing the GT3 R was the latest 3.8-litre Porsche 911 GT3 Cup, which will compete in the 2010 Porsche Mobil 1 Supercup supporting selected Formula One races. However, the GT3 R - which weighs just 1,200 kg (2,646 lb) - has a larger 4.0-litre six-cylinder 'boxer' engine delivering 480 bhp and other technical developments designed to improve the performance of the car further still.

    For example, an anti-lock braking system, traction control and an electronic throttle with 'blip' function on gearbox down-changes make it much easier for drivers to get used to the GT3 R race car than the prior Cup S model, with the consequence that the new car is also more appropriate for the ambitious amateur racing driver rather than purely experienced professionals. The main focus with this new car was to deliver even better driveability and easier handling.

    Additional flared wheel arches front and rear emphasise the purposeful, wide track of the GT3 R. And like all second generation versions of the 911, the new 911 GT3 R also comes with striking LED rear light clusters. For optimal aerodynamic performance, the underbody of the car is completely covered and features a rear diffuser and, compared to the prior Cup S model, the range of adjustment on the rear wing has been increased.

    The highly-developed suspension can also be adjusted extensively; at the front are height-adjustable MacPherson struts with variable SACHS two-way shock absorbers and double coil springs (main and auxiliary). At the rear, the GT3 R features a rigidly mounted sub-frame with a height-adjustable multi-arm axle together with adjustable SACHS two-way shock absorbers and double coil springs.

    "Since we announced our intention to launch the 911 GT3 R, demand has been huge," said Uwe Brettel, Head of Motorsport Sales. "The number of GT3 R vehicles we had planned for 2010 is almost sold out."

    As the newest Porsche race car, the 911 GT3 R has an incredible provenance. In 2009, the ultimate racing Porsche 911 – the GT3 RSR - won the GT2 Drivers’ title in the FIA GT Championship, the GT2 title in the American Le Mans Series and also in the Le Mans Series of endurance races, and also triumphed in the gruelling 24 Hours of the Nurburgring race.

    Like the 911 GT3 Cup and 911 GT3 RSR, the Porsche 911 GT3 R is designed and built by the Porsche Motorsport Department at the company’s Weissach Development Centre.

    How do you know the next GT3 will use 4.0L Metzger motor?  Maybe I am confused, but are you just concluding this based on Preuninger's vague comments about next generation GT3 possibly continuing with the GT1 motor and then applying the specs of the GT3R?  If so, this does not seem very definitive.

    If there is more reason to believe this is the truth, please correct me.

    Thanks!

    Is there a method to the naming convention with these variants?

    We have GT3, GT3R, GT3RS, GT3RSR; alternating back and forth between street and track only.  It made a little more sense before when the GT3R was a Cup/CupS.

    a little.

    Great announcements here though.  Don't they seem to be opening the curtain a little sooner this go-around?

     edit: can't wait to see the GT3RSRSR - that should be a monster!

    Dave,

    I think the convention is:

    GT3 (street) -> GT3 -R (race)

    GT3rs (street) -> GT3rs-R (race)

    BUT, I remember back in the days of the 996, we had GT3 cup and GT3 RS(r) as race cars...
    Also looking forward to the GT3 RSR-S Cup streetversion btw ;-)

    Almost :

    The GT3RS is the homologation model (street car) for both the GT3 R and the GT3 RSR.

    It is a little confusing , but it will all get easier as the word is that this is the last year for the RSR.

    What we will most likely have is as follows:

    GT3 (street)

    GT3 RS (Rennsport - Street)

    GT3 R (Racing)

    Yes, it did not go un-noticed. 4.0 litre + sequential Smiley

In 2009, the ultimate racing Porsche 911 – the GT3 RSR - won the GT2 Drivers’ title in the FIA GT Championship, the GT2 title in the American Le Mans Series and also in the Le Mans Series of endurance races, and also triumphed in the gruelling 24 Hours of the Nurburgring race.

    Like the 911 GT3 Cup and 911 GT3 RSR, the Porsche 911 GT3 R is designed and built by the Porsche Motorsport Department at the company’s Weissach Development Centre.

    I hope you are right, but I read a mag that quote Anderas Preuninger said 3.8 is the largest displacement for the street car instead of 4.0 on the race car.


    Re: Porsche 991 GT3 to include GT1 motorsport engine... Thread Closed

    Spyderidol:

    What we will most likely have is as follows:

    GT3 (street)

    GT3 RS (Rennsport - Street)

    GT3 R (Racing)

    Interesting.  So the R replaces the Cup, and the RSR goes away?  Then only one race 911 for the near future (til Hybrid comes in I guess)??

    Aren't the Cup and the RSR applicable to different groups?

    I LOVE the body of that R by the way.  It does look more like the RSR than the Cup to me.

    great post.
