the 'selectable drive modes', unfortunately is a feature included on the Premium trim. However, there is a Sport mode in the AdvanceTrac system on base model cars, in addition to the sport mode on the transmission (AT). To access it, press the traction control button twice quickly and watch your info display. What does this do, specifically? Have not figured that out yet. Have heard that it 'relaxes' the AdvanceTrac system, allowing more aggressive driving/maneuvering before the system intervenes.
