Good catch.

Splitting hairs here, but I'm not sure I'd label them "tiny" though. When I think nearly-inappropriately tiny, I think of the 330 mm 4-piston setup on a base Carrera. This is a little better.

What do you think drilled rotors do for you?

I hope GM puts a little more screen in front of the heat exchangers, they'll get easily torn up on US roads.

This appears to be the base-model, but drilled or slotted rotors have nothing to do with the quality or performance of the brake system, as you likely know. Further, it’s difficult to tell, but appears to be a 2-piece rotor, which is a pretty high end setup. The previous GM efforts have a history of right-sized brakes for their weight and power with many best-in-class figures, so I wouldn’t be worried. Of course, asthetically, I think massive brakes look great and some of the worst looking autos out there are trucks with massive expensive wheels and dinky little brakes or even worse: big forged wheels over drum brakes. These are not forgiveable.

If the base model C8 is going to be priced near the C7 just because it doesn't have cool-looking slotted/drilled rotors, then great, maybe I'll consider a 'Vette for once.

(note: I did consider the C7 with a Z51 package, but ended up with my Z4...)

For the record I was just using the pics as a determinant of what model they are testing. For instance the C7 C51 pack has slotted rotors. So one could come to the conclusion this is the base model.

Yes drilled rotors are basically a gimmick. All they do is increase the chances of rotors cracking. Basically an old tech that has remained around for aesthetics. Slotted rotors do remove pad glazing, but can increase pad wear.

The rotors are definitely small. Thanks to an idiotic R&T article, some internet fodder has been going around the ME Vette was lapping the ring under 7min...testing some high-hend ME Vette. The top range C8 will be wearing some big carbon ceramics and big aero, to try and dip under or near 7min. Clearly you can tell this is the base model car they are testing, most likely mid 7min car around the ring at best.

The Vette forums will have thinking the mid-engine Vette will be $180k and conquer the world. All they are doing is creating hype that the car will never be able to live up to. They are base model test cars clearly from the pics.

I can't imagine base being that expensive, maybe highest edition, but if the current ZR-1 and ZL-1 1LE are any indication, it probably will conquer the world.

Maybe try something that works in the cold? With good ol' dinosaur juice? Partial to Formulas myself. Although will likely run Saints or XTR Enduros on my next bike now that Shimano is finally serious about 1x.

That's a myth to a large extent.

The thing about mineral oil is that there's no standard for it, so the companies are free to develop whatever they want, as a result, the fluids can have radically differing properties. Magura is a good example of this, their fluid did not test well at low temps (German quantitative tests). The XTRs work just fine for me down to -20°F. Sure, they are stiffer, but they still work and you don't need a lot of braking when it's -20 anyway. I have actually done -20 with one XTR and one Formula, they felt exactly the same. It's not that the fluid goes bad with Shimano, it's caliper seals that get very hard and stiff. If I was regularly riding colder than this, such as Fairbanks, I might go for Avid mechs, but overflow can be a big issue in the winter and can render any brake, especially a mechanical, inoperable. On solid-ice sections with studded tires, you want at least some brake.

The real problem with Shimano is that they don't offer any replacement parts, seals, etc. Due to this, they are "throwaway" brakes that you can't keep going season after season. I get about 2 seasons and they give out, my old XTs did (ones that I actually don't ride in these crazy cold temps). That left me without a rear brake on a vacation and I was pissed. They also weep a little fluid if you let them sit for long periods of time, that I can deal with though-knowing a sure method to clean the rotor and pads. I can't deal with their cheap disposable brake philosophy. Probably go back to Hope, although I didn't have the best experience with their power back in the day.

First two pictures are around low-single digits to zero. Last picture was a 100 mile race (turned into 120) where the temperature much of the time was around -10. As I said, the coldest I usually ride is about -20, it's not that cold here often, but back in the mountains in February and March it can be.

The rotors on the other hand, those are pretty amazing. The aluminum heat-dissipating fin sandwiched in between the steel braking tracts seems a few generations beyond what we use on cars today and they work great. On my XC bike I can run a small rotor and not overheat it on some pretty crazy descents.

Plus, Formula brakes now use mineral oil too:

Yeah, part of my reason to now consider the Shimanos. Hadn't considered the parts issue, but makes sense as that's one of the reasons I've always run Campy for my road bikes.
