What are the facts and differences compared to the 997? I know that not much information has bee released but I want to know your opinions and ideas, seriously, please, especially with the engine. Could Porsche shift to 8 cylinders instead of six?

6 cyl boxer engine has a power stroke that is efficient and high reving as its in a Boxer configuration, the V8 has a similar power stroke but is bulky and 2 cylinders heavier.
The torque and power outputs of the flat 6cyl boxer engine a very remarkable.
The 911 is rear engine RWD the 968 and 998 are front engined and RWD.
The 911 is lighter and more agile, the rear engine rear drive eliminates long prop shaft and gives you a Formula one style engine gear box configuration. Porsche have nailed it with the 911.. as much as i hate to say it its a pretty all round performer and a quality car.
it will have LED technology in the headlights and the taillights as used on the Carrera GT and use a flat 6 engine in natural aspirated and turbocharged versions
To answer your question regarding the use of V8s, the 928 was front engine and RWD. It had a V8. Then you have the first generation Cayenne S, Cayenne Turbo, and Cayenne Turbo S. Then you have the second generation Cayenne S, Cayenne GTS, Cayenne Turbo, and soon to be released Cayenne Turbo S. All of those have V8s. I believe they’re bringing back a car to commemorate the 928, which should be V8 and front engine. There a few reasons why they use the H6. A couple of reasons are, lower center of gravity, and going to eight cylinders in the 911, Boxster, and Cayman, would make the car harder to drive because of the added weight in the back. If you ask me, I think they should’ve put the 3.8 H6 in the new Turbo and new GT2 instead of wasting time with the 3.6 H6. The concept of the 911 is small displacement and high revving. Furthermore, they have not always used six cylinder engines in the 911s. The early 911s used four cylinder engines.
The 997 is being update with a freshening up of the front air dam, rear air dam, and the taillights are being updated and will use LEDs.
The 998 will be another update to the 997, and will have two lenses inside the headlight assemblies kind of like this 8, the lenses are stacked and verticle inside the headlight assembly. I have not seen the back of the 998 concept.
There is no reason too. Porsche’s 6 cylinder engines are faster than more than 85% of V8 cars out there.
And they go just as fast as Ferrari F430 V8 and Lamborghini Gallardo V10 engines.
Porsche also makes the most fuel efficient supercars and high-end sportscars.
6 cylinder engines are also lighter and can rev higher, so it makes the car lighter and handle better.
I hope they never switch to 8 cylinder engines.
I’m guessing here but I believe a key reason for the retention of the flat-6/boxster engine is that the design offers a significantly lower center of gravity than does a V-configuration engine. Beyond that, a V8 engine simply would not fit in a Boxster or Cayman chassis and likely not in a 911, either.
A final and non-technical point: Porsches are steeped in tradition and many of their customers buy into that tradition. Anything other than a boxster engine would likely incur the wrath of the traditionalists and, hence, a likely large portion of their customer base.
v8 are heavier hence worse handling and agility
also they are much less fuel efficient
6 cylinders are very balanced and smooth. V-8s are always imbalanced in the firing order; disturbing the natural exhaust scavenge sequence. When say a Small Chevy fires 5 and then 7 on the same drivers side bank, an unwanted interval between exhaust pulses on the other bank slows scavenge and actually disrupts the flow of things. Same happens on the other side between 8 and 4. This is just something that is not real proper in a high performance car and many manufacturers engineer around it by using a more proper number of cylinders. I personally prefer 6 in-line. 12 opposed is nice too. Very smooth.
they could at anytime but they would have to spend a lot of money in R&D and they feel it would be better spent on other things.
If it isn’t broke don’t fix it
I don’t think Porsche has released any info on the 998 and they are pretty good at keeping a secret at Weissach. The only thing for certain is the engine will use the revised direct injection mode of fuel injection for better efficiency (about 15-20% better gas mileage over the previous generation of engines (like the V8′s in the old Cayenne versus the new Cayenne). Porsche has and will probably stay with flat-6 engines for the 911 line of products because to go V-8 is a radical departure from the “Porsche Scriptures” written in stone since 1960′s. The characteristics of the traditional flat six engine is lower center of gravity, perfect balance in rotational harmonics, and lighter weight compared to a V8. These are hallmarks of the 911 ethos and works in perfect harmony for almost 50 years now. To keep the 911 rear engined and going to a V8 will upset the balance (weight distribution of 40/60 frt/rear) so carefully managed so far with suspension and dynamic handling trickery developed for this configuration. Porsche has answered this question quite convincingly in producing a V8 which they use in their SUV, or later 928, Panamera (2009 debut), a V10 used in the Carrera GT, and their flat 12 in their 917′s. The 911 will forever use the flat-6 in normally aspirated or turbocharged form (capable of 500-986H.P.) which is better designed for a rear/midengined configuration car that will be competitive on road or track against all competition.
The new Zune browser is surprisingly good, but not as good as the iPod’s. It works well, but isn’t as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that’s not an issue, but if you’re planning to browse the web alot from your PMP then the iPod’s larger screen and better browser may be important.

This is getting a bit more subjective, but I much prefer the Zune Marketplace. The interface is colorful, has more flair, and some cool features like ‘Mixview’ that let you quickly see related albums, songs, or other users related to what you’re listening to. Clicking on one of those will center on that item, and another set of “neighbors” will come into view, allowing you to navigate around exploring by similar artists, songs, or users. Speaking of users, the Zune “Social” is also great fun, letting you find others with shared tastes and becoming friends with them. You then can listen to a playlist created based on an amalgamation of what all your friends are listening to, which is also enjoyable. Those concerned with privacy will be relieved to know you can prevent the public from seeing your personal listening habits if you so choose.
I’ll gear this review to 2 types of people: current Zune owners who are considering an upgrade, and people trying to decide between a Zune and an iPod. (There are other players worth considering out there, like the Sony Walkman X, but I hope this gives you enough info to make an informed decision of the Zune vs players other than the iPod line as well.)
