Technology, in the context of the Subaru WRX STi, is less about entertainment than driver control. This is not a car for the casual driver or the uncommitted nonenthusiast. It has ferocious power, and its suspension is optimized for high-limit cornering--at the expense of ride comfort and normal levels of interior noise. It's loud enough inside that, at speed, you won't hear the audio system all that well, but you'll be too busy driving to care.
