The 2013 Audi S4 has updated gauges and simplified climate and infotainment controls. Standard on this model are 12-way power heated front sport seats wrapped in leather and Alcantara, along with a power sunroof, triple-zone automatic climate control, flat-bottom sport steering wheel, and aluminum dashboard trim.
The S4 with Prestige trim is equipped with a 505-watt Bang & Olufsen premium sound system, Audi MMI Navigation Plus with a reversing camera and rear park-assist sensors, adaptive front lighting, Audi Advanced Key, and Audi Side Assist technologies.
A new Driver Assistance package is available this year that includes adaptive cruise control, dynamic steering, and Audi Drive Select technology. Audi Drive Select provides driver-selected Auto, Comfort, Dynamic, and Individual settings.
Vehicles equipped with the MMI Navigation Plus package now have Bluetooth audio streaming capability, as well as Audi Connect mobile Wi-Fi providing Google search by voice and Google Earth maps. Additional upgrade options include Nappa leather, power rear window sunshade, and more.
