Default The new PCCB on a Cayenne Turbo

I got a nail in the tire and when there to pick up my car I noticed a Cayenne Turbo. This is the new PCCB offered . It is my understanding it costs a bit less than then yellow version and are a bit less expensive to maintain . This is just informal chat that I had and it was not with my usual folks that I chat with (so don't hold me to accuracy on it). I did take a photo . They are actually quite beautiful . They are large and look like a silver glass .

I believe the new Cayenne Turbo has the new Porsche Surface Coated Brake (PSCB) versus the current Porsche Ceramic Composite Brake (PCCB). PSCB's surface consists of tungsten carbide (chemical formula: WC). Tungsten and carbon form a mixed crystal so hard that it can be used to cut glass. Tungsten carbide is one of the hardest materials in the world after diamond, and around ten times harder than gray cast iron—which is precisely what makes it so interesting to brake engineers.

Thanks for the link . With the dramatic changes in Porsches engine philosophy its nice to see something new which looks very appealing . I liked the way the brakes looked on that Cayenne .

I know this has been stated before many times, but the rear end of the new Porsche Cayenne is just terrible...it doesn't even look like a Porsche's anymore from the rear. That generic light bar is horrible, and makes the Cayenne look like a bunch of other SUVs on the roads today.

The others are right, not PCCB. PCCB appears to have fallen out of favor. The much touted benefits of less unsprung weight for tracking falls prey to the cost of replacement. From the horses mouth, Porsche: https://www.whichcar.com.au/news/for...brakes-porsche

The short story is PCCB was touted as lasting the life of the car - not. VERY expensive to replace. Now sold as just a way to not have to clean the brake dust.

Interesting huh?

Wonder if we will see this as an optional brake upgrade for Macan in the future.
I would buy it !

I think these might be a very viable braking alternative in terms of cost and performance. You don't get the weight savings of carbon ceramics, unfortunately.

I could not agree more and shared my thoughts on this topic in another post. It feels like Porsche hired interns from the design team at Lincoln and Dodge and since they had to show they were doing something they proposed to change the rear of all Porsche cars. That is the result there. A totally unnecessary change. A beautiful rear that needed no change but they did for the sake of changing something. I am still in no need to wear glasses to drive but every time I see a light bar on a car in front of me from a distance I never know if it is a Lincoln, a Dodge or ....... a Porsche.
