• 2012 New Porsche 911 (Porsche 991)

Know anyone who seriously thinks the current Porsche 911 needs replacing? Probably not. But Porsche thinks otherwise. The 2012 new Porsche 911 will be replaced later this year by a car that’s as new as its looks are familiar.

It might look nearly identical to the old 997 series, but almost everything about the new 991 series 911 has changed, including the philosophy behind the car itself.

We will know a lot more when we actually drive the car later in the year, but for now, after a day riding shotgun in the new Porsche 911 through the mountains of South Africa, it is safe to conclude that this is a Porsche 911 like no other we have seen to date.

What Has Porsche Done This Time?
The answer is to start again. You can argue that the changes that turn the 997 into the Porsche 991 are just as comprehensive and significant as those that ended the reign of the 993 in 1998. Sure, there is nothing quite so culturally shocking as the abandonment of air cooling for water radiators, but the overall transformation into the Porsche 991 is at least as significant.

Perhaps most fundamental is the way the new car is made. Roland Achleitner, the man in charge of reinventing the Porsche 911 says, “I am neither an aluminum nor a steel man — I am a correct materials man.”

His philosophy explains not only why the bulk of the new Porsche 991 is now aluminum for lightness where once it was steel, but also why ultrahigh-strength steel has been retained for use in the major crash paths, particularly in the route over the A-pillars and around the passenger safety cell. Had it been built like the 997 the car would now be a minimum of 120 pounds heavier; in fact, it is lighter by a small but still significant (and undisclosed) amount.

The next big change involves the wheelbase. Since its launch in 1963, the Porsche 911’s short wheelbase has been a defining characteristic of the car much like the flat-6 engine in the trunk.

But now, and for only the fourth time in 48 years, that wheelbase has been extended. By how much we can’t say, as our access to the car was made on the condition that we would keep certain details under wraps. We can say that the extra space between the wheels does more than merely provide more legroom in the back; it fundamentally affects the character of the car.

Drivetrain Remains Familiar
The engines are probably the least altered part of the car, but only because the direct-injection flat-6 (unrelated to all previous Porsche 911 engines) has only been in production since 2009. Even so, the 3.8-liter engine used in the “S” model gets a useful power gain to 400 horsepower, while the standard motor actually shrinks in size to 3.4 liters but offers 350 hp, 5 more than the old 3.6.

Porsche won’t give 0-60-mph times yet, so we’ll guess. Figure the base car will get there in around 4.6 seconds and the S in 4.3 seconds, an improvement of 0.1 and 0.2 second respectively. Directing this power to the rear wheels alone (though all-wheel drive is naturally in the pipeline) is Porsche’s familiar PDK seven-speed gearbox. Nothing too surprising here, you might think.

That is until we realize that one of the cars charging east from South Africa’s Atlantic coast toward the Indian Ocean has a manual version of this transmission. And if you thought a stick-shift PDK was a contradiction in terms, you are not alone. But there it was, complete with three pedals and seven speeds. Porsche hasn’t actually said it’s going to use this gearbox in production cars, nor did it talk about any alternative, so read into that what you will.

Electric Steering Invades the Porsche 911
Not content with changing the way the 911 is built or extending its wheelbase, Porsche has not been afraid to meddle with the 911’s most precious possession, one even more key to the car’s character than its flat-6 engine. It has replaced the hydraulic power steering used by every 911 since assistance was introduced in 1989, with an electric system.

If this sounds like a minor, backstage detail, it’s not. We have yet to drive a car that’s been improved by electric steering, and driven plenty that have been ruined by it.

Moreover, Achleitner freely admits that the steering of a 911 is “the most important thing to get right.” He says that he spoke to a huge number of suppliers and that ZF got the job because its system is so good, “you would not be able to tell it is electric.”

So What’s It Like, Then?
There’s a huge sense of occasion when you step into a next-generation Porsche 911, even if it’s as moth-eaten as the two hard-worked prototypes pictured here. It is like going to see an all-new production of a much-loved movie: You know it will be bigger and technically more impressive, but there’s no guarantee the heart and soul of the original have been preserved.

The interior, such as we could see behind the camouflage, was good. But quality, ergonomic efficiency and visual presentation have all leapt forward. This is a cockpit with much more in common with the Panamera than any previous 911, and that can only be a good thing.

Sadly our pleas for even a quick drive fall on deaf ears. Even so, there is much we can discover, even without a steering wheel to handle. The engines are as sweet as ever and spin a couple of hundred rpm higher, to something very close to 8,000 rpm. Predictably the smaller engine needs more of these revs to really perform and greater use of the gears, but in a car such as this, many might think of that a bonus.

Despite a near identical output, the 3.8-liter unit is not in the same specification as it is in the Carrera GTS, but you’d need the two side by side to tell the difference. It is smooth and more responsive in the midrange than you’d credit an engine that, let’s not forget, is pumping out well over 100 hp per liter.

This is probably the right time to mention that both engines also produce substantial improvements in fuel consumption. The final figures are not yet in, but they’re likely to register a double-digit percentage gain.

Handling Feels Spot On
But as the 911s head up into the mountains, it is not the acceleration provided by those engines, or the near instantaneous shifts of the PDK box that most grab your attention. It is the chassis.

We’re in the 3.8-liter car and have asked Achleitner to drive as fast as he knows how, which, you’ll not be surprised to know, is really rather fast. What’s curious is the apparent disconnect between the way the car is attacking the mountain road and the complete lack of drama in the cabin.

Part of this is because both the driver and the electronic safety nets are both very good at their jobs, but so, too, does the 911 appear to have found a state of grace missing even from the 997. Once he comes steaming into a downhill left-hand corner, apparently too fast, forcing him to stand on the brakes as he turns into the curve, just as the camber of the road starts to drop away. It’s a situation that would have given even a 997 more work than it would have felt comfortable doing, but the 991 simply sheds all the necessary speed as if it had been braking on a flat, smooth and straight road.

What can be read into this? Clearly that Porsche’s goal of making the Porsche 911 more stable and secure than ever before has been realized. However good the driver and support systems, any car that can do what that car did is an exceptionally safe device. To be driven in this car and think its bloodline runs back to those twitchy, tricky devices of the mid-1960s is to see how very, very far the 911 has come in the last 45 years.

What’s Left?
But still there remains something we don’t know, something we will not find out until Porsche allows us to swap seats and actually drive the new Porsche 991. And that is the price that has been paid for this newfound security. Until we can sit with the wheel in our hands and feel the response through our fingers, it’s hard to say how much is the car and how much is the driver.

We can say that we would be astounded if the new Porsche 991 is anything other than a capable, effective and shockingly fast coupe, no matter the driver. We know from the quality of its ride and quietness in its cabin that it will be better over long distances than any other Porsche 911. Only one question remains: After all is said and done, will it also be regarded as a great Porsche 911? Only driving it can tell us that.

Edmunds attended a manufacturer-sponsored event, to which selected members of the press were invited, to facilitate this report.
