CAR WARS! Porsche 911 Edition — How Does The Newly Turbocharged 991 Compare Against The Naturally Aspirated 991?

CAR WARS! Porsche 911 Edition — How Does The Newly Turbocharged 991 Compare Against The Naturally Aspirated 991?
Only months ago we asked you WHICH Porsche 911 would be more desirable: The 991 with or without the turbocharger?

While we're waiting to see if the used Porsche 911 market rewards the naturally aspirated car, our friends across the pond have done something rather interesting. Autocar got its hands on a 991 equipped with the newly turbocharged six-cylinder mill AND one of the origial 991s using the naturally aspirated powerplant.

So, how did it shape out? See the writer's closing thoughts below:


...So I’ll leave it this way. The new turbocharged 991 is the better car and, should you require such a thing, the easy winner of this test. For 90% of not just drivers but 911 drivers, it is superior at least 90% of the time.

As for the engine, Porsche should be congratulated for doing so well a job that, I suspect, it didn’t much want to do in the first place. Just remember this: when you extract your 911 from its day-to-day drudgery and take it somewhere and let it go, it is old normally aspirated car that has the freer spirit, the more infectious enthusiasm. It is, in short, more like a 911. Or how a 911 used to be. However good this new car is, and it is very good indeed, it can do nothing to take that essential fact away...


Being that we're all enthusiasts here, I am just curious: Though the turbo'd version is better 90 percent of the time over the naturally aspirated car, would you still buy it over the turbo-less car?

Eventually, I'll have no choice, but for now, GT cars are said to remain NA and so will I...

It's amazing how much pontificating the Autocar article does without actually saying anything. Quite obviously the day of the turbo is at hand in the industry which is necessitated by the simultaneous need to meet emissions and provide performance.

I'd rather have a naturally aspirated engine of the same horsepower output as a comparable turbo if I am going to keep the car "forever" for durability issues. No matter how well a boosted engine is made, it is under more stress and therefore likely to fail sooner.

Given how many premium cars are leased, this will not be an issue to owners who tell JD Power how happy they are.

I'm sure Porsche's turbo is quite nice.

I tried to love the 996, 997 and 991 turbos that I have owned, but never could. Not that these weren't great, powerful cars, but they just never grabbed me. A combination of slight lag, vacuum cleaner sound, and the feeling that the engine was straining after 6000 RPM (combined with heavy weight) just killed the enjoyment for street driving. I get far more pleasure from my Cayman GTS than I did from the turbos. Maybe Porsche has made such vast improvements that I'll be pleasantly surprised, but until then its NA cars for me.

I have a Turbo S that I will likely keep a long time. But if I were in the market for another, I would go with NA. The turbo is powerful but its nonlinear response can be misinterpreted when you try to be civilized on the street. It's a beast on empty country road though.

I think the turbo in the standard Porsche 911 is less of a fun engine in comparison to former N/A car versus the turbo in the Ferrari 488 versus the 458. In the Ferrari there is "zero" perceptible lag period. In the Ferrari 488 the engine sounds reasonably close to a 458 but forcing to shift 1000 RPM lower in the rev band. That takes away the last bit of crazy shrieking noise. However compared to F360's and F430's it actually sounds pretty good. The 911 new turbo engine does sound better than the 911 turbo. However compared to N/A engine it is about 50% as nice in sound. The trade off is much improved low and mid range thrust at a lower RPM. Thing is Porsches were never about low RPM performance. What has made them fun from early 911's was revving them from 400 RPM to red line and hearing that classic flat 6 howl. Porsche has now taken that away from customers. Lets hope the 4 cylinder turbo versions in the Boxster/Cayman sounds better and is a more engaging engine. The supercharged V6 in the F Jag sound much better to my ears now. Porsche seems to be systematically taking away all the characteristics that make it a unique car to drive.
