Transmission options vary between the two models. Both the A5 Sportback, Cabriolet and Coupe only come paired with a 7-speed dual-clutch automatic gearbox. S5 models are equipped with an even more outstanding 8-speed Tiptronic automatic transmission that features 4 separate modes of driving. (Comfort, Auto, Dynamic and Individual)
The entire A5 lineup gets Audi's Quattro all-wheel drive system, which sends 60 percent of power to the rear wheels under normal driving, to give these models more of a performance character and a more balanced feel in tight corners. S5 models get a sports differential that helps distribute power to further aid performance.
Cabriolets feature a power-folding acoustic soft top that can be operated at speeds of up to 31 mph; it also has enough thermal insulation for winter use, and special attention has been paid to trunk space. Even when folded, the top allows enough trunk space for a couple of small weekend bags. The rear seatbacks can still be folded forward to access more space. The setup also includes LED reading lamps and a heated rear window.
Depending on how much luxury is desired, there are three different trim levels: Premium, Premium Plus and Prestige. S5 models are available only in Premium Plus and Prestige trims.
Premium models of the A5 include a panorama sunroof, 10-inch infotainment MIB 3 infotainment system, heated power mirrors, rain-sensing wipers, heated windshield nozzles, leather upholstery, a power driver's seat, cruise control, 3-zone automatic climate control, Bluetooth hands-free connectivity, HomeLink universal remote, Apple CarPlay / Android Auto and a 10-speaker, 180-watt sound system with auxiliary input and SD card slot. Premium Plus trim adds a 505-watt Bang & Olufsen sound system with 14 speakers, xenon headlamps, LED tail lamps, heated front seats and driver's seat memory settings, among other items.
Key options include the Audi adaptive cruise control, which applies the brakes as necessary to keep a safe following distance and is packaged together with Audi Side Assist. Heated and ventilated seats are also available. The comfort front seats in the cabriolet circulate warm air at neck level to allow you, perhaps, to have the top down in cooler weather.
The Audi Connect system is also available, utilizing a dedicated Internet connection for the vehicle to form its 4G LTE Wi-Fi network. The system also works with Audi's hard-disk-based navigation system to allow easy streaming Google Earth imagery for maps, live Google Search and live news, traffic and weather.
