Two master cylinders but where? In one unit or separate? That clips gives me more questions than answers.

....old vs new

 

That brake package on the right looks interesting.

Looks like a master cylinder with brake actuator & skid control module all bolted together as one unit.

I will watch your video.

 

Discussed here in a Juniper Reddit thread, and also in Autogefühl’s typically excellent juniper drive test

What I get out of that reddit thread and the info in general brake pedal force is "simulated" and stopping is done via regen when the battery can take the charge. Unless more than regen stopping is needed. I don't see how this is much different than we've seen in hybrids for many years.

 

It sounds like he's saying you get thre same brake pedal feeling & feedback whether using regen or hydraulic brakes?

That's cool, it would feel odd if there was a change in how the brakes feel, Imo

 

That looks dramatically more similar to a "traditional" steering setup than I expected it to for some reason. Very recognizable column, rack, etc. Interesting stuff, thanks for sharing!

I wonder if they use hydraulic feedback to the pedal to make the feel consistent regardless of whether regen or friction brakes are being used. Could that be the reason for a second master cylinder (likely a much weaker one)?

 

my lc500 has toyota's vgrs (variable gear ratio steering) - i believe it is entirely mechanical... pros/cons? i guess a big pro on the tesla one is it can be reprogrammed/tuned via software.
but i do love the vgrs on my lc in combination with rear steering.

 

This is very strange - see screenshot below refering to the fact that only the new Y does blend braking (friction/regen) when pressing the brake pedal.

My 2016 S has always done blended braking when pressing the brake pedal - I can see the Regen graph in real time and it always shows Regen (same change in the graph when taking my foot off the accelerator pedal) when i apply the brakes. I'll shoot a video and post it later as I know I'm not imagining this.

Edit: I know for a fact that my car has always had blended braking simply because when the battery is charged to 100% or is very cold, when I press the brake pedal, I can see there isn't any Regen showing on the energy graph.

And when either of the above conditions are not true, when I apply the brakes, Regen always occurs and is clearly visible in the energy graph.

Blended braking on any Tesla has always existed and is very linear and smooth.

I'm sure any Tesla owner here can speak to this:
@AMIRZA786 and @LeX2K .

 

I'm glad you brought this up. I think there is this general idea that electric vehicles are completely different vs. ICE but chassis, suspension, brakes and even some driveline components are the same. In other words doing repairs and maintenance on an EV is largely the same as any ICE car.
But it already feels about the same. Pedal feel on my Y isn't perfectly linear like my gas only cars but overall I barely notice. @AMIRZA786 has driven the new Y, owns the new 3 and owns the old Y if anyone would be able to give clarity here it would be him.

 

Unfortunately, I didn't enable the new Regen mode, but I did notice that the brake position never moved, even when using rengen braking where friction braking was needed. In both my Y and Model 3, it will blend braking with regen when needed, and that results in the brake pedal being depressed, changing position. The brake remained in the same position the entire time until I actually needed it

 

Yep I understand this aspect but Lars Moravy makes it sound like there is some profound trickery going on maybe I'm misunderstanding him. The brake pedal movement doesn't bother me because I'm not generally touching the pedal anyway.

 

I think what he's talking about is more related to FSD, the brake pedal never moves while the car is using FSD

 

Got it. I haven't purchased FSD because I'm not on HW4 and don't see the point. It's supposed to be much better on HW3 now but still I don't see the value especially when I'll be buying a HW4 car anyway.
