Brembo's new lightweight brakes
Does anyone know if Mercedes is already using these, and if so on what models? They look to be less expensive than a typical two-piece.
The new brake disc concept, conceived by Daimler with Brembo as its fundamental partner in developing the product, is a 10-15% lighter brake disc that combines two different materials: cast iron and steel. The most important advantage lies in the steel housing, which is just 2.5 mm thick instead of the 7.5-9 mm of a conventional cast iron housing, with the same level of performance. The results in terms of reducing fuel consumption and having less of an environmental impact are excellent.

I wonder why this is supposed to be a big deal given there are many low weight brake rotors on the market with reusable aluminum hats?

This seems to be a reasonable street option for MB (and maybe Cadillac) between the heavier full cast iron rotors and the more expensive two piece aluminum hat/cast iron rotors. The two piece rotors may be saved for higher performance cars or special performance options and the steel hat rotors for more mid line offerings. Hope they have a coating for the steel hat that will stand up to corrosion and rust.

Seems like they got the best of both worlds out of this, and were able to manufacturer at a reasonable cost. Disconnected hats are going to be inherently more expensive to produce due to the other engineering involved to make them robust. The different and thinner (stronger) metals of this hat will similarly transfer less heat to the hubs (not get as hot and cool more quickly). AND they weigh less for the other benefits described above. That they figured out how to combine these two in one industrial step, in a cost effective way, is the trick. Think of it as a 1.25 piece.
And look at the surface area of the hat. That has to help cooling.

Agree, this is a mass production design trying to find a compromise between cost and performance. Not competing with sports oriented 2-piece brakes.

I wonder if it's easy to find these rotors? Sounds like a great alternative to the P30's, although I'm honestly not too too concerned with the price of two piece rotors given the longevity of rotors on our cars (I'm going on 63k miles, and I know, in need of replacement).
