Default Ford picks TRW steering system

Quote:
DETROIT--TRW Automotive Holdings Corp. is launching its electrically powered steering-rack drive system on the 2010 Ford Fusion and Mercury Milan cars.
Electric steering uses 7 percent less energy than a conventional hydraulic system, decreasing fuel consumption and reducing carbon dioxide emissions. It also eliminates such components as the steering pump, pulley belt, reservoir, and hydraulic lines.
TRW, of suburban Detroit, makes steering, suspension, braking, engine, and occupant-restraint components and systems.

That's pretty cool. Wonder if it's prone to breaking.

I've been in a 2008 Ford with this feature, while I'm not sure it's the same brand or not. None the less the car had 3k miles on it and the PS system was gone.

Electric power steering is not new. I tried it in a Saturn 5 years ago. Most manufacturers shy away from it due to the vague nature it gives the steering, so it stays to more pedestrian models. Although, someone is using it on a performance car where it got a good review, but I can't remember where now.

BMW 5 series, including the M5. IIRC.

The old Subaru XT6 had an electric hydraulic pump for the PS, insted of an engine driven pump.

Is there still a mechanical connection to the steering rack so your not screwed if the electric motor dies.

Yes. I believe that most of these systems wrap a planetary gearbox around the steering shaft. The motor can act to speed up or slow down the shaft in relation to the steering wheel, depending on how fast and what direction the motor turns the planetary.

MINI has electric PS and the steering is as sharp as it can get. I love it, but hope it doesn't die any soon as it's expensive to fix.
