Porsche going all-Turbo?

[techweenie]

That's the rumor - future 911s...

Video link didn't work.

But an all turbo lineup would not be surprising, it seems like the future for many car companies.

BMW is pretty much already there. All 4, 6, 7 series BMWs are now turbo'd. All M cars are turbos. And most of the 3 and other series, too.

Try this.

I think it could make sense. Smaller engine in the lower priced vehicles, reduce weight.

'Lower priced' being in the $90K range...

Since they're owned by VW, and VW has more turbocharged vehicles on the road than any other manufacturer, it makes sense.

And 'reduced weight' being in the 3000lb range #porkche

last i checked, the 911 was in the 3400 lb range.

I don't see anything wrong with it. If their base model become a turbo 4....then yeah. Me no likey.

Anywhere from 3042-3500 depending upon options, and that includes the turbo which is the fat bastard of the group.

Whats wrong with a Turbo 4? If it packs the same whallop as the old 6? I'm pretty impressed with the new turbo 4 cars floating around.

I bet the Focus ST with its turbo 4 would surprise you.

I don't need a reason! I'm a grumpy old cuss, thats why! Now leave me alone whipper snapper.

6>4

I'm yet to experience a 4 that feels as good as a 6. It's much harder to dampen the torsional vibration of a 4. BMW replacing their super smooth straight 6 with a turbo 4 in some models was an epic fail for enthusiasts. Go compare a Subaru flat 4 and a Porsche flat 6 and get back to me. Power output is just one small part of the story.

True Matt. But in the days of being required to increase fuel efficiency... Some tradeoffs will be required.

And I'm surprised how quiet the ecoboost on my escape is. several times now I have hit the start button twice because it didn't sound or feel like it was running...

[M.D. Holloway]

Last year didn't Porsche bragged about how they were able to achieve remarkable performance both off the line and top end without having to go turbo?

No matter, I think it the right thing the do and while your at it super charge the line as well!

And yet, when you add the extra 2 cylinders suddenly your crankshaft has torsional vibration problems... even Aston Martin couldn't make an inline 6 work at Le Mans in the LMP class. Flat 6 crank is a little shorter and stiffer than an inline 6 so Porsche has done well, but remember the first long stroke ST's and RSR's? And the 917's central PTO to get around the vibes?

Boxer engines have no net reciprocating forces since each piston cancels the other, but they do have moments which don't cancel from the opposing forces. A boxer 6 has only 6th order and higher moments, so very small, boxer 4 has 2nd order and higher moments, which is not as bad as the 2nd order forces that cause an inline 4 to bounce. Boxer twin has net primary moments, so kinda big, but since it is a moment you can more easily dampen it with widely spaced, soft mounts.

Bottom line is that a boxer 4 strikes a nice balance between, um, balance, and a rigid crankshaft, which allows higher rpm and more boost.

I will say that nothing sounds as good as a 911 flat 6. Well, maybe a 917 or a Ferrari V12.

The question is whether it is worth the extra hundred pounds for the sound, and whether you are going to make full use of the extra cylinders to get 50% more power.

I look at it as Porsche going back to their roots... don't forget the first 15 model years were 4 cylinders.
