The Porsche 911 is my favorite car because i feel that it is everything a driving machine should be. And when you purchase one. You have like 15 different ways to get it one and then there is the manual or tiptronic choice for most of those.

So why not a Diesel. Performance diesels are on the rise and i feel like it would work if made properly. It could be a great development, kinda something based on TDI or something Porsche could do all their own.
 
I thought diesel was for tractors

Yeah

How about that 90hp 1.9-liter TDI from the Jetta?
 
Brilliant!

Mmmm.. The sound of that flat 6 revving to 4200 rpm... Sweet !...
 
There aren't any diesels that'll fit. Subaru is just starting to make flat four diesels... a flat six? Maybe never?

The best you can do with a current-generation CRDi is about 5000 rpm... any higher and it's in danger of blowing to kingdom come. The best fit for a Porsche would be a 3 liter flat-six diesel, because it'd weigh around the same or just a little more than Porsche's current 3.8. But at best, such a plant would be making only 270-290 bhp... not quite 911 power. Bump it to over 300 bhp and it'd be laggy, peaky and would make power over a very small rev range. Would be interesting to drive, but nowhere near as much fun as a gasoline engine... not yet.
 
Pfft, old turbodiesel flat 4 from old RR caravelles etc will be just fine.. bit more boost etc and it'll have more torque than gasoline counterparts
 
Are there any Cayenne diesels? (just checking to see if Porsche even make diesel engines)..

This 911 could be something to compete with the R8 TDI! :dopey: if it fits in the rear of that why not a 911.

Ive never been a fan of diesel despite what people say... yes it gets you further but there something magical about Petrol! :crazy:

Of course we all know that Porsche loves to change their cars. That radical headlight design for the 996 was probably a 3-year battle for the designers.
 
I don't think a heavy torquey engine would do the handing of RR porsches any favours to be honest. BMW have shown you can make a sporty car with a diesel engine, but a sports car... Hmmm.

But some of the diesel bashing is just a little neanderthal.
 
For some reason, to my ears the whole thing sounds kind of like this...

BEN: A what?
BILL: A Diseasel, I think. There's a notice about them in our shed, "Coughs and Sneasels Spread Diseasels." you had a cough in your smokebox yesterday, it's your fault the Diseasel's here.
BEN: It isn't!
BILL: It IS!!!
BEN: IT ISN'T!!!

Meh, I'd think something like the Panamera should have a diesel, not the RR 911. Big, heavy engine out behind the rear axle could undo 30 years of engineering work. A turbodiesel Cayenne would be right up most trailer-puller's alleys.
 
What handling? they're still butt-heavy, soggy nosed evolution beetles, nothing can change that. Unless they make the whole rear bodywork out of CF, which would raise the price by 1/4..
 
the last time they did a diesel...

theyv got a bit of development to do...

Look people - Clarkson is here !.....

Wrong by design maybe, but there's no denying they're bloody fast and handle extremely well..

I reckon with turbocharging that a powerful flat 6 diesel wouldn't be out of the question. It could be made compact too. If BMW can get 100bhp/litre out of their 123 diesel (2 litres, twin turbo) then a 3.5 flat 6 twin turbo diesel could reasonably produce 350bhp and an enormous wallop of torque (and lets be honest, on the road torque is much more important than power - can you imagine how much shove you'd get on the autobahn in a diesel 911?)

I know that as capacity increases the efficiency increases at a lower rate (so a smaller engine is more likely to develop higher bhp/l) but Porsche have the technology (especially being part owner of VW) to make an efficient and powerful large diesel.

It's also not unusual for Porsche to have shared technology with Subaru so I'm sure Subaru could share their experience with their new boxer diesel should Porsche decide to put diesels in their mainstream sports cars.

On the higher-revving note, Honda is known to be developing a 'Type R' diesel engine that has the potential to rev to 7000, as they've said they'll never make a sports diesel unless they can give it the Honda USP of being high revving and exciting. The Mercedes Bluetec diesels work on a similar level, being much smoother and able to produce power like a petrol and torque like a diesel. So a high revving diesel wouldn't be out of the question either.

Also, with a boxer engine it's naturally balanced, so has lower internal inertia and could be made to rev faster.
 
Lets keep the diesels for something more suitable please. The last thing a rear engined car needs is a heavier engine hanging back there. The only Porsche i can see with a diesel in it's line-up is the Cayenne, but why bother? VW already has a V6 and V10 diesel in their version of the Cayenne.

Yes Audi are putting a diesel in their flagship sports model R8 but then again they have a LMP1 diesel racer and shift a huge proportion of their other models with diesel engines, so it makes sense for them.

...and was so universally panned that it changed back for 997. In fact if you look at the basic shape of the 911 you'll find it has essentially remained unchanged since the 911 911. It's kind of like Connery though - it's put on some pounds and added some lines, but it's still sexy and powerful.

Porsche does change the cars though... once they released some sort of truck thing that women buy.

Not entirely correct - The Cayenne Turbo S will put you way into 911 Turbo territory...

Universally panned by the press and a very small bunch of enthusiasts. Most people who buy Porsches buy them to pose in, so wouldn't have given a damn about the look of the 996 after the 993. Unfortunately I do get the impression rather too many people who buy even the Turbo or the GT3 just buy them for the badge rather than any track ability.

Personally the 993 is my favourite 911 (followed by the original), I don't mind the 996, and the 997 looks a bit too VW-beetleish from some angles. And I know the irony in what I said there.

Tru dat... although pretty much all of the 'enthusiasts' don't look too kindly on the 996 both stylistically and in terms of abilities... I've heard good things about 997 but we'll have to see how it plays out with perspective...

Porsche doesn't have too many of these numbers left. What comes after 999? 1000?!

They'll probably go retro and call it the 911 again. Or the stillborn 901 name, though Peugeot would probably have the same hissy fit as they did fifty years ago...

I have a feeling many just buy the base model, so they can say they have a Porsche. Just a feeling though, I don't know the sales numbers.

I don't know if Peugeot would have a leg to stand on. The 997 / 996 / 993 / 964 names used to identify the various generations of 911 are internal model names. The cars are not badged that way. The 911 was originally going to be badged as a 901, which is why Peugeot complained.

Sorry, Doug, I just couldn't let you off the hook for that one.

Turbo, maybe... but buying the GT3 just for the badge is like buying an EVO RS to impress your dates on trips to the coffeeshop... just doesn't work.

As we're getting all retro.



OWNED.

PWNED, is more like it. w00t! w00t! :lol:

RE: High revving diesel. I suppose if, and only, if, they can get a diesel that'll rev to at least 6000 rpm, Porsche might consider it... but still, the idea of having a heavier iron lump behind the rear wheels might force them to make the 997 even more 'retro' than it is now and give it a front overhang the size of a Suzuki Swift to balance out the weight. The current overhangs are about big enough to hide a Smart Fortwo under the 911's skirts... any more overhang and the front and rear wheels would be stuck in the middle of the 911's doors.

One Porsche sportscar that could take a diesel is the Cayman. That would actually be interesting to see. Maybe a 2.7 liter turbodiesel with 300 bhp? That would hit the spot.

My thought too!

The 917 looks the right dimensions for a diesel engine... or maybe a restyled (or not) 962?
