Hummer SUV
It is military chic, but brutalism in architecture had roots in reinforced concrete bunkers and gun emplacements dating back to the First World War. Hitler's Western Wall in France was full of gun emplacements evidencing brutalist style. Therefore, a commercial Hummer, a Chevy suburban with a brutalist exterior treatment qualifies IMHO.

Giant Dump Trucks...

Much of Dieter Rams
Much of Dieter Rams work has long seemed more connected to brutalism than minimalism.

Stefan Zwicky...
...produced this. Not exactly mass-market, but certainly brutalist.

Willy Guhl's Eternit planter
It's quite "brut" in the way the material is used and also has obvious resemblance with brutalist architecture.
In the other meaning of the word it's also a brutal way to accommodate plants; take this nature!

Now THAT gives new meaning to lack of lumbar support!! 🙂
Seriously, this piece says so much about brutalism.

Those planters are acutely brutal!

Brutalist Sculpture
by Oscar Niemeyer in Brasilia, if we dare call a sculpture a product.
Interesting, I really wouldn't call most of his architecture brutalist. His constant juxtaposition of the gigantic with the delicate seems always to leave his architecture just shy of the threshold of the brutal.
But the sculpture pictured...he crossed the threshold.

Brutalist furniture in the Paul Evans style...
from our very own DA Design Radar. It seems more a juxtaposition of primitive and modern, rather than purely brutal, but it certainly fits into a broad definition.

E15 stool
if this aint brutalist i dunno what is.
for the record the dieter rams designs are austere functionalism in my opinion..... they are much too elegant and sleek to be considered brutalist says i.

Another try at Niemeyer Sculpture...
It is the horizontal slab sculpture in the left of the frame.

Chewbacca...
Regarding Dieter, austere functionalism is close to how I used to refer to Rams. Mine moniker was minimalist functionalism. But as I began to study Renzo Piano's engineered functionalism, and minimalism, and then think about formalism vs. functionalism, it leaped out at me. Dieter is largely a geometric formalist concealing engineered function in much the same way that a car stylist conceals a chassis with body. Once I got this, then it was a matter of looking at the forms and asking are Dieter's forms closer to the internationalist, or the brutal. To me his products are so much about surfaces, rather than space and neutral bouyancy found in internationalist style. So: he fits much better in the brutal. What I do like is your choice of "austere." In combination, I think "austere brutalism" describes Dieter Ram's rather well. An alternative would be "rational brutalism," in the sense that Rams' rationalizes the brutal what is essentially brutal.

Paul Evans
I'll add to Dcwilson's great find at our DAradar, also the pic of the matching chair, that's also interesting, but the table is more pure, in the style of Paul Evans.
And the second is a console by Paul Evans.
