When Apple introduced the iPhone 4S earlier this year, the loudest buzz centered around Siri. Apple's so-called "Virtual Assistant" lets users make appointments, add reminders, search Yelp and Wolfram Alpha, send emails and text messages, and control the phone's built-in music player.

The obvious question for us was whether Siri would work in a car when tethered over Bluetooth. The short answer: Yup.

When you hold down the iPhone's home button, Siri is essentially treated as an incoming phone call, fading out the audio and then playing the chime indicating it (she?) is ready for a command.

We tested Siri on a variety of vehicles, including two Mercedes-Benz products, a Chrysler 300, a Dodge Charger and a Nissan Maxima. The results were mixed, with some commands going through easily and others requiring a few attempts. Based on our experience, it seems that the mic placement and the level of cabin noise present make a predictable difference, and the Maxima we shot our video in tended to provide the best results. See for yourselves after the jump.

      Works great in my Audi A5... And yes, it uses the car's mic as opposed to the iPhone 4S' mic.

      Just got the Iphon4S this weekend and found out it worked with my SYNC system in my 2011 Fusion. It helps out alot!

      I've been using Siri in my 2012 Acura TL with no problem. Too bad I can't summon her from the car control, but have to use the home button.

      I discovered this on accident in my Fiat. Works perfectly!

      Well, I know from personal experience it works with Ford's SYNC and MyFord Touch systems. Glad to see it working with other makes/models as well. http://ford-life.com/2011/10/26/how-siri-completes-microsoft-sync/

      I'm really curious to know if those tested vehicles' infotainment systems have bluetooth "voice passthrough", or if the iPhone 4S is simply using the car's speakers for audio and using the phone's on-board microphone to listen to your commands....which I think is the more likely the case.

      Thanks for doing this. The car is probably the only place I'd want to use Siri. Good stuff.

      I'd be more interested if I knew it worked with the 'phone' button on the steering wheel...

      FWIW, the old "limited function voice control" of the 3Gs also works over bluetooth in the same way. I'v used it in my Dodge Magnum SRT-8 over the U-connect system to name dial numbers.

        Exactly. I don't know why this is news. The voice control in my iPhone works fine with my 1998 BMW. Now if holding the "talking man" button could trigger the iPhone instead of the BMW VR system (hmmm... I wonder if I DISABLE the BMW VR...)

      Siri works perfectly fine in my vehicle, never had a problem nor would I expect to have one in any other vehicle. Regardless, I think I might be the only person on earth who hates their iPhone. I've got a 4S and had a 4 before it, and I'd much MUCH rather have an Android device. I think Siri is a useless feature as it stands now. Dictation is a hit or miss affair, and you always have to check it before you send a text/email. I guess I can't complain too much when it is 100% free and my company foots my phone bill.
