Lol these are fun.

For something so big it's just a little bit silly...

But the brakes are not so hilariously shocking. The difference is way to much, that's not just the tyres.

Look at it this way...

At 70mph, the Urus (4850#) is carrying 1.077 MJ of kinetic energy. The CT (6843#) is riding a whopping 1.519 MJ of energy. ~50% more energy to get stopped from 70mph. That ain't nothing to sneeze at. Yep, gonna take a whooooole lot more than just the tires to stop in the same or even comparable distance. And just for fun, I looked at how much heat we are looking at dissipating.. The CT rocks in at 1439.3 BTU.

To be fair I think the Urus is on carbon ceramics
I'll see if I can calculate the braking distance tomorrow. But it doesn't look good. Maybe brand new pads or something?

This is what the Cyberbeast is for. It's a supercar in a truck body. If that's what you want, why talk about towing and range. BTW, range on that Lambo is only 277mi.

Doesn't stop CT from having a larger brake setup in those huge 35".

Plus regen should be able to nearly handle the difference by itself. Lambo is ICE with no regen. At 2sec from 70mph that's only 750kW total.

How about the difference being 1000 kg ? One third more weight, I think the result is great.

Regen has absolutely no effect on braking distance unless the brakes are woefully undersized.

I want to see the CT pitted against the Raptor R and TRX. No one ever questions whether or not they are "real trucks". To see them get stomped in every "truck" and "speed" metric for 15% less in price would send a clear message.

685lbs of torque is quite a bit lower than I expected. Still amazing machine but I certainly expected tq to be very close if not higher than the hp

Am I going to have to school you on tires and brakes too? Not to mention the 50% more mass? Mud terrain tires will never beat dedicated street performance tires, no matter how strong the brakes.

The Cybertruck has anti-lock brakes strong enough to bring the contact patches of the tires to the limits of traction. After that the only advantage of more powerful brakes is the ability to do repeated stops without fade. Since the braking test was only from 70 mph (and only one stop), we can be sure the problem was not inadequate brakes.

Let's keep it real.
