Makes sense, Porsche's diesel engines were badge engineered from VW, while their hybrid tech is widely considered to be the best in the "money is no object" hypercar class. Hybrid also plays better with their electric car ambitions.
That's pretty old. Around the 2013-2015 model years they upgraded the coatings in the fuel pump and injectors to accommodate the higher corrosion potential, mostly due to glycerin-bound water, in biodiesel.
As far as I know everything produced today is B20 rated or higher. The fuel systems are all made by the same two manufacturers for the most part.
That's interesting, thanks for the links. Since they're using the same Bosch high-pressure pumps and injectors as everyone else I don't see any real reason for the restriction, except perhaps some conservatism in the specs. There's nothing about B20 that would bother any part of the engine or emissions systems once the fuel components are up to date.
I suppose they may simply be running out old spec stock. Anyway, to your point, it is disappointing. Along with the whole defeat device thing.
wouldn't the astm spec for B20 (or any other blend of biodiesel) keep the level of glycerin, soaps, methanol, water, etc. low enough for that not to be an issue?
I thought methyl-esters as a solvent would be better for the the engine anyway.
But I had a guy tell me two weeks ago that he uses B100 in his new Mercedes wagon despite its 'blue tec' technology.
"Only use diesel fuel with a blend of 5 % biodiesel (B5) or below."
Don't fall for the FUD. I've been running B99 for 15 years in my 98 Jetta TDI. Everyone else had to replace their injector pump because of the switchover to ultra low sulfer diesel. I'm still running my original injector pump with 275,000 miles and counting. Biodiesel is easier on the engine, lubricates better, and smells better. And most importantly it doesn't add CO2 to the atmosphere.
Every time I wake up in the morning and I'm still in the good old USofA, everything I touch has a petroleum component associated with it. Before, I was putting a tankful of CO2 into the atmosphere along with its associated manufacturing footprint every time I filled up. For the last 15 years I've eliminated the part that comes out of my tailpipe. One more benefit: no money goes to the Middle East to fund wars and mayhem and the MIC. It stays local and helps the local economy.
That's just a standard disclaimer. Has anyone actually tried it?
VW documentation says to use B5 or lower in my car, as well, and it's known to be one of the best engines ever for biodiesel. The previous owner and I have run B99 in it for years with no problems at all.
It's not much different from running Linux on your computer. Just because they don't test it that way doesn't mean it will necessarily cause problems.
Some would contend that Porsche never made diesels at all, but I understand that sometimes great companies make terrible mistakes like the Macan and Cayenne
It would be really fun to have a waste veg oil burning Porsche though
Yes, but what damage has it done to the brand? They're now a manufacturer of quick family cars, not purely sports cars. Now they are in the same class with Maserati and Lexus for coolness, not McLaren and Lamborghini.
This isn't something that can be bought back. "I drive a Porsche" doesn't have the same implications it once did.
Lamborghini makes a family friendly Urus; guess it's just a quick family car brand too.
And the Urus manages to be even more flagrant brand engineering since it's an Lamborghini version of a Porsche Cayenne, which is just an Audi Q7, all based off an VW Touareg.
If there's a current Porsche vehicle hurts their brand, I think it's the Panamera. All their other vehicles are either sportiest in class or best in class, but typically both; the Panamera is neither.
But Porsche haven't gone anywhere near full BMW yet, and BMW is still cooler than Maserati and Lexus. I think Porsche's brand value is doing just fine. Not every car manufacturer needs to be McLaren/Ferrari/Lamborghini/Koenigsegg/Bugatti, and arguably, Porsche was never part of that group.

The Lamborghini Urus shares the same VW group platform as the Audi Q8 and the Bentley Bentayga. [1] [2]
The Q8 is just a rounder body on the Q7/Touareg platform with the Audi engine with the Porsche turbo from the Cayenne instead of an Audi supercharger. The Bentayga is also a Touareg derivative but with a Bentley W12 or Cayenne Turbo V8TT. Bugatti is also working on their Touareg clone presumably with a Bugatti W16 engine.
They're all the same car with different packaging. The biggest giveaway is all of the clones use Audi's pretty distinctive rear air suspension system, the odd for Audi/VW rear wheel steering, and the uncharacteristic for Porsche/Lamborghini ZF-8HP automatic transmission.
Porsche’s success has meant many other “cool” brands following suit.
Also Lamborghini, by your metric, ceased being cool when they released the LM002. Were they still cool between the years they ceased production of the LM002 and began production of the Urus?
Really does suck for cool kids these days. Can’t buy RR, Bentley, Maserati, Porsche, Lamborghini, and soon enough Ferrari ( after they release the Purosangue). Oh and to play it safe avoid Aston Martin, because the DBX concept.
'Porsche will focus on gasoline, electric and hybrid vehicles because demand for diesel is declining, the Stuttgart, Germany-based manufacturer said in an emailed statement on Sunday.'
There is this guy I know in Los Altos Hills who does this in his driveway. He always has 2 gas->diesel conversions going at any one time either GMC/Caddy, VW or Merc. I'm sure the guy could convert the used petrol Cayenne my stepfather just bought, but there's really no point unless you're biodiesel-ing / out in the country / carry your own fuel / use lots of generators.
Porsche has not offered any diesel models in the European market since Feb 2018. Diesel was always a minor part of their line-up and not a great fit for the brand, so this move isn’t hugely surprising.
It would be a much bigger victory for environmental campaigners if the wider VW group were to join Porsche, Toyota, Volvo, Subaru and Fiat Chrysler in announcing an end to diesel in cars.
I think the whole Dieselgate affair was a huge benefit for the future of electric cars. Because at least in consumer cars the uncertainty surroundig possible limitations with driving into cities (in Austria and Germany) if you have a diesel car will almost erradicate this market segment in the next few years.
Its one of the nice little policy levers you got as politician. Just ignore a "crime" for long enough, to have it entrenched and when you need the motion, get sharp on it.
Frankly, every government of a developed nation should have a plan for complete phase out of diesel vehicles in the near-term with very few exceptions. There is simply no such thing as a diesel powered automobile which does not have severe detrimental health impacts. Yes, it's a very challenging technological problem to tackle, diesel engines have great utility, but that's no excuse for tolerating the deplorable current state of things.

Risk of engine damage and/or damage to the fuel system if diesel fuel with a higher concentration of biodiesel than 5 % is used like B11, B20 or B100.
Only use diesel fuel with a blend of 5 % biodiesel (B5) or below.
----------------------------------------------
If I cannot even put B20 in it, there is not point for going with diesel, Cayenne Diesel is the slowest and most un-porshe Porsche!
As far as I know everything produced today is B20 rated or higher. The fuel systems are all made by the same two manufacturers for the most part.

I do not think there is 2019 Cayenne Diesel model, but I do not see anything other B5 or less.

Manufacturing bio diesel creates CO2.

* 918 Spyder? Thank the crossovers and Panamera
* Cayman GT4 and Boxster Spyder? Thank the crossovers and Panamera.
* 911R and GT3 Touring? Thank the crossovers and Panamera.
* GT2 RS? Thank the crossovers and Panamera.
* The 911 Speedster that should see production? Thank the crossovers and Panamera.
* The track-only €701,948-priced 935 they're making 77 copies of? Take a guess what helps make it happen.
HN headline is v misleading
