Porsche 911 designers have the easiest job in the world. A nip here, a tuck there and "boom", new 911. Pictured above is a prototype 991 911  (Source: Jamie Lipman/Inside Line)

Porsche's 911 will get a major overhaul for 2012

We reported earlier this week that Porsche is looking to add what is essentially "cruise control on steroids" to its future vehicles. The Porsche ACC InnoDrive system will take full control of throttle inputs and "learn" the routes that the driver regularly travels. Only the steering will be left for the driver to control when the system is enabled.

Now, we're getting some more information on the most famous member of the Porsche family: the 911. The next generation model will be revealed before the end of this year, with production models going to North American customers next year.

The new 911, codenamed 991, is growing in length again. The 911 will sit on a 4-inch longer wheelbase, while overall length grows another 2.2 inches. Compared to the last air-cooled 911, the iconic 993, the new 911 is roughly 10 inches longer with a 7-inch longer wheelbase.

Despite the expanded dimensions, the new 911 will be lighter than outgoing 997 variant. Instead of relying primarily on steel for the construction of the vehicle, the majority of the vehicle will now be constructed of aluminum with high-strength steel being deployed used for "major crash paths" according to Inside Line.

The extended wheelbase will also leave more legroom for the two rear-seat passengers (in reality, kids only) and for an optional hybrid system that should be available for the 2016 model year refresh of the 991 platform.

The hybrid system isn't the only concession being made to improve fuel efficiency for the 911; Porsche has also done the unthinkable and ditched the 911's wonderful hydraulic steering system for an electric one. Porsche 911 project manager Roland Achleitner explains that the excellent steering feel will remain and that "you would not be able to tell it is electric." Another buzzkill is that Porsche is moving to an electronic parking brake for the new car. 

When it comes to powertrains, the new 911 Carrera will share a 3.4-liter flat-6 engine with the Boxster S that produces 350hp. The Carrera S will be blessed with a larger displacement flat-6 producing roughly 400hp. Power will be delivered to the rear wheels (or all four wheels in Carrera 4 guise) using a 7-speed dual-clutch (PDK) transmission or -- wait for it -- a 7-speed manual transmission.

Overall efficiency is said to improve by 12 to 15 percent over the outgoing model.

For more information on the next Porsche 911 and the development of the car, you can check out Inside Line's write-up. They actually got some passenger-seat time with a prototype of the vehicle.

RE: I like manuals but 7 speed ?

But I doubt Porshe will do anything but add two or even three overdrives, which will pretty much make 6th and 7th worthless for top speed. Gear ratio calculators don't equal real life examples.

Are you kidding me? 7-spds allow tighter gearing in 1-6 for quicker acceleration all the way to top speed, while 7th is for high speed interstate cruising.

You're thinking of the Camaro, Mustangs and certain Corvette models that will only top in 5th due to the necessity of the super tall 6th gear to achieve decent mileage figures.

Exactly right! I have a Formula Firebird with the 6 speed. Don't remember first through third, but fourth is a straight 1 to 1, fifth is 1.25 to 1 and sixth is 1.5 to 1.

The top speed of the car was 151 in fifth gear. It would only get to 140 in sixth, the engine didn't have enough torque to spin to redline against that 1.5 to 1 ratio. That from a motor whose torque curve was so flat that it made at least 300 ft/lbs from 2000 rpm through the 5800 rpm redline

On the other hand, I was turning just 1500 rpm @65 mph. I had to get up to 88 mph just to see 2000 on the tach. (insert time travel joke here) Made for some excellent mileage for a 350 ci iron block, push-rod V8. I routinely got 28~29 mpg on highway trips and got above 30mpg quite a few times. (best being 32.5)

I know American cars aren't generally as sophisticated as European ones, but I think I got a hell of a bargain out of mine. How many mid 90s era cars can top 150, do 0 to 60 in 5.0 sec, the 1/4 mile in the high 13s and corner at better than .9 g? All for an out the door price of $19474. I drove it home in Feb of 94 and I've just started shopping for it's replacement.

You just made my arguement. 7th will not be for top speed. It will be supertall, for exactly the same reasons as you mentioned.

That was my original assesment that's the OP's mpg vs gear range example was unrealistic in a production car.
