GM says today that it has found a way to link Siri to the new infotainment systems in its two smallest cars, Chevrolet Spark and Sonic.

What’s interesting about this is that Chevy is launching this feature on a minicar and a compact model ahead of doing it on luxury brands. You’ll need an iPhone, of course, but if you have a 4S or 5, you’ll be able to activate Siri using steering wheel-mounted controls.
