I guess if the electric motor jams, the steering will be blocked, especially since the worm gear ratio is so high it cannot be driven by the crown...

Kinda defeats the safety purpose of having a mechanical connection from the steering wheel to the shaft.

I'm not a mechanical engineer and I look at this and see F-A-I-L!

@RustyRazor2010 i am a mechanical engineer and i see the same thing there is no type of limited slip/torque converter in the electric motor shaft so if/when the motor seizes/fails steering would be lost.

no me gusta si se corta la electrisidad o hay un problema girara loco o probocara un accidente !! yo no probaria esa tecnologia!!

@Mieden can save even more power when all the electricity is gained through braking recovery systems rather than an alternator so yes more than likely the future due to less wasted power on the engine.

FAIL!

Don't looks safe to me.

@looncraz Thanks

VWs been using this in Rabbits and Jettas for half a decade. It fails like a hydraulic rack would...no more dangerous than any other setup, and the electric motor consumes less "HP" than a hydraulic pump. No one is complaining when they pass the gas station...

@NissanAltima2005 Basically, yes. The lack of a viscous coupling means if the motor freezes/jams/seizes steering is LOST. Viscous simply means liquid/fluid.

Electric motors also have a bad habit of having intermittent failures, sometimes surging and "bucking" along the way, which could cause the car to turn on its own, fighting the driver.

A torque converter (viscous coupling) would reduce the likelihood of this manifold, but the video doesn't show one.
