Finally official proof. Excluding the possiblity of brake computer going haywire, from this video we can see and guess severael things. One, when the guy said he applied the brakes and nothing happend.. He was lying. 2. He might not have been able to get it into neutral for a reason. He might not have held it, he might have simply panicked and tried to jab it into neutral which doesn't do anything. But we can see that forgoing computer malfunction, the brakes should have stopped the guys prius.

--But I have to laugh at when he puts his foot down. Heck, even my cavalier accelerates faster than that!

But that is something that should not be excluded. After all, it seems that Toyota's mechanical fixes in the recalled cars are not curing the problem, so what's left is the electronics...

Well, what I simply mean is that barring the computer malfuction, these are not possible.. That means either it isn't happening (not likely) or it IS a computer malfunction.

The hydraulic brakes are still there, with the computer behaving or not.

And like previously stated, the engine can't provide power to the wheels without the assistance of the motor generators, so multiple systems failure is needed to get into a situation where there's extended acceleration (up to the limits of the battery charge), but the hydraulic brakes are still there.

But it does not turn in 55mpg.

Well the car is being examined. For everyone's (including Toyota's) sake, let's hope that the examination is being conducted by third party engineers, Toyota engineers, with supervision by law enforcement (so Toyota cannot conceal any evidence).

Better yet, broadcast the examination live, nerds like myself would like to watch. It would have a lot more substances than broadcasting old man Toyoda being grilled by our politicians.

No but if it had the 4 speed O/D automatic or the 5 speed it could turn 40+

Yap my first thought a 90mph prius wow.. I was skeptical now.. i've always thought the braking power is like 4x the hp of most cars? but i cant seem find anyone who dynos they're brake system lol.... I'm just curious why toyota's getting such a bad rap is the case or it's mob mentality setting in?

If you really wanted to alot of cars are tested for braking distance. You could probably sit and figure out something like brake force exerted if you were really into it.

Canberra (Oz) used to have a brake dyno as part of their rego test. Way better than a brake performance test, it compared each wheel for power and balance.

Was getting a ZA Fairlane tested next to a Porsche 9-11 one day. Fairlane won on the front end, Porsche won on the rear.

Brakes are hooked into the regenerative system; I don't think you automatically get hydraulic braking. Testing a non malfunctioning system just proves it works most of the time. It is the "some of the time" that is of concern.

In my opinion there is a serious problem with the electronics in many toyota's i wrote about that over 3 months ago.. We are thinking that when we rebuild engines of toyota's maybe we should have a rider to our contract signed with the customer this is a serious problem!

 

[crazyoildude]

maybe he was going downhill ????

They will do over 100 mph.

The hydraulic brakes are always at the end of your pedal, but there's the electronic "brake feel" thing while the electronics looks after the regenerative aspect.

Panic stop, and you are straight into the hydraulic system.

The number of faults that a Prius would have to endure to get the computers to a) provide drive in the first place, b) provide full acceleration, and c) take the conventional braking system out of the loop (ABS fault ??) is mind boggling.

Seriously, I'd declare the car possessed sooner than imagine all of those odds stacking up.

NHTSA and Toyoa could not replicate SUA: http://hosted.ap.org/dynamic/stories/U/U...EMPLATE=DEFAULT

Some interesting points from the article:
"Every time the technician placed the gas pedal to the floor and the brake pedal to the floor the engine shut off and the car immediately started to slow down," the memo said.

The report says that, according to Toyota's "residential Hybrid expert," the Prius is designed to shut down if the brakes are applied while the gas pedal is pressed to the floor. If it doesn't, the engine would "completely seize."

The memo continued that in this case "it does not appear to be feasibly possible, both electronically and mechanically that his gas pedal was stuck to the floor and he was slamming on the brake at the same time."

The findings raise questions about "the credibility of Mr. Sikes' reporting of events,"

The brakes on the Prius also did not show wear consistent with having been applied at full force at high speeds for a long period, the Wall Street Journal reported Saturday, citing three people familiar with the probe, whom it did not name. The newspaper said the brakes may have been applied intermittently.

CNN reported today that it was all a scam. The guy should have thought things out a bit better. Should have put on some worn out brake pads, and some heat scored rotors, maybe even had shoes with worn our soles. aka Fred Flintstone style...
