new info on 991 model year 2012
2012 Porsche 911 Carrera: Anchoring a revised lineup is a base S-model packing a downsized 3.4-liter version of the evergreen horizontally-opposed 6-cylinder powerplant. Despite less displacement, the 3.4 reportedly makes 350 horsepower, up five from the current base Carrera's 3.6-liter unit. Next comes a new Carrera RS, replacing today's S-model. It uses the same 3.8-liter engine, but with 15 horses added from 2009 tune to make a nice, round 400. Torque outputs slide a bit, down by eight lb-ft to 280 for the 3.4 and by 15 lb-ft to 295 for the 3.8. Even so, a substantial weight drop--at least 130 pounds by our reckoning--should yield slightly better acceleration times, plus better fuel economy and lower CO2 emissions. While it's still way too early for precise numbers, sources hint RS models will scale 0-60 mph in about four seconds. Improved agility and stability were major goals for the 2012 Porsche 911 Carrera, hence the new materials mix. Reports indicate a thorough chassis fettling to go along with it. Though suspension geometry apparently stays much the same, the front struts and rear multilink hardware are said to be reworked for less body motion and better cornering control.
Sources also expect bigger brakes with more stopping power. Another lengthy options list will again show heat-resistant carbon-ceramic brake rotors, plus 20-inch wheels as a new alternative to 18s and 19s. In addition, the next 911s switch from hydraulic to electrohydraulic steering, which saps a bit less engine power as a minor means to better mpg. Last but not least is a bevy of new aerodynamic aids that also aims to save gas and improve stability. The 2012 Porsche 911 Carrera will boast a racing-inspired "active aerodynamic" system. Dubbed Porsche Active Aero Balance (PAAB), it combines the usual speed-linked motorized rear spoiler with new front air-intake flaps that open or close as needed to manage airflow and drivetrain cooling, and a series of perforated air ducts in the wheel arches. Together, these features are supposed to suck the car closer to the pavement at most all speeds for less body motion, especially at the front, and improved stability at high speeds and in sudden throttle changes.
In addition, Porsche reportedly plans to replace traditional door mirrors with a pair of small TV cameras, this to reduce total air drag. A small screen at the base of each side of the windshield displays what lies behind. Though we've seen this feature on many futuristic concept vehicles, the 2012 Porsche 911 Carrera would be the first regular production car to offer it.

3.4 in the S model? I hope there's none of the same issues with that block as prior years. I wonder what kind of suspension they're running to fit the 20's; and tire sizes to fit the wheel wells. bigger rotors for every model would be a plus as well as standard ROW M030 suspension.

The report is silent on the most radical change - a 4" wheelbase increase. The 991's wheelbase is longer than the Cayman's.

Great for those times when I really need to reduce drag to conserve fuel: when I'm routinely doing 160mph on USA highways risking criminal charges for reckless endangerment.
Will improve my fuel consumption by .003mpg?
Repair costs for these 'mirrors' when warranty runs out: $5000.00?
Pays for itself after one million miles?
What ARE they thinking? Trying to seduce gadget freaks?

The specs look attractive. But the naming strategy doesn't make sense. If Posrche stays with this nomenclature, the new S and RS will make less power than the existing S and GT3 RS. That just won't do.

They are just devaluing the designations. Customers will know better.
