I'm now an official NSX Specialist, just got back from Ohio...

I was not aware there is no direct connection between the brake pedal and the hydraulic brakes.
Does the brake pedal work like the throttle pedal and activates an electric motor to push on the brake master cylinder?
I would have thought for safety there would have to be some way that the brake pedal can work the brake master cylinder.

What about the drive for the valve train?
if not belts or gears how do they do it?

JD,
As Elistan pointed out the valve train is handled with a chain which in my opinion is pretty cool. There is enough new technology on this car that as a future owner I would like to know what additional maintenance items are needed.

The braking system is listed as "electro-hydraulic" which is something I am completely unfamiliar with and am curious to learn more about.

JD & NSX_2k,

I don't want to give away too much but as someone working on this technology I figured I could explain a little on this.

Most of the " brake by wire" units have a hydraulic system with valves where when the system is working and energized correctly, you are actually pressing fluid into a chamber through a valve ( not directly into the calipers) which is measured and this signal is used to drive a motor/ some power unit that builds fluid pressure at the calipers and in turn braking torque. When the system fails, the hydraulic unit is denergized and now you are pushing fluid directly into a calipers like non-power assisted brakes. This is the fail safe that is federal requirement. Also, Honda could tie the pedal feel in these units based on the modes you are in ( they could but would they do it is a question for another day )

Local dealer, Suburban Acura, just told me that it is mandatory that they keep the car for 60 days while the paint cures, is this true? Saw your post about no wax or film but are you retaining the car?

My dealer, fresh from Ohio, mentioned the 60 day period but nothing about delaying delivery due to that. That sounds bogus.

He said they recommended against even *washing* the the car unless you hand wash with simple mild soap (I wasn't planning on taking it through the free car wash as Chevron). The explanation they gave was that they don't "bake" the car after painting to accelerate the curing, so it takes time. Unclear WHY they use this process, as it is pretty annoying.

Incorrect but you must sign off on the delivery checklist saying that you void the warranty on the paint if you wax or film the car before the 60 days. There will be several disclosures to sign upon delivery. Launch control, Track use, etc

For a fun comparison (for whenever you guys get your cars)....here's R & T doing 50 launches in a row in a 991 TTS:

BTW, no disclosures to sign.......

Not surprising as the NSX's are coming right from the factory to the dealer.
I would guess for other Acura's there is at least a 60 day delay between completion of manufacture and arrival at a dealer.

Ravi,

Thank you for the overview on how the system works! Quite interesting really. I presume that since there is actual fluid in the system, it will likely need to be replaced at intervals similar to what we have on our cars currently.

 

[neuronbob]

Sounds, again, similar to the RLX Sport Hybrid braking setup. The RLX has both brake by wire and a hydraulic system backup. Page 473 of the owners' manual indicates that brake fluid is to be checked one a month and regardless of mileage, to be changed every three years. I assume this frequency will be more often in a tracked NSX Sport Hybrid.

Yup, you still have fluid like the regular system and would have to be replaced/ bleed ! I wish I could explain more for about but I am tight lipped for obvious reasons and as the neuronbob commented, most of the hybrid cars with regenbraking have some kind of brake by wire.

I might have seen you there!

I was there 5/2-5/5, training was on 5/3. I'm from Acura of Fremont.

You mentioned you were surprised about bolster wear. Understanding there were maybe "thousands" of people in and out that car ( can see it happening), did it look really bad to be of concern? Red was one of my choices.
How did the other interiors look wear wise?

Here are my hot laps. I didn't get the video from the Pro Driver on mine for some reason.

nice

Yes nicely done for someone with so little seat time!

Impressions?

 

[pinkertonpunk]

I really enjoyed it! It would've been nice to put the car in track mode as I've read that it really helps the car turn in. I would've liked to turn the stability control off but I understand why we had to leave it on. It was pretty effortless to go quick, though. No throttle on oversteer to speak of but the tail really wants to come around with a bit of trail braking. Would be great to get more clear laps in with the car. We got those two laps, and a couple laps of a smaller track as well, so not much seat time.

Looks like a fun time. Congrats.
