The 2018 Audi A4 delivers just about everything you expect from a small luxury sedan. Standard feature highlights for the A4 Premium include 17-inch wheels, automatic xenon headlights, a forward collision mitigation system, adjustable drive settings (Audi's Drive Select), a sunroof, an auto-dimming rearview mirror, leather upholstery, heated power front seats, tri-zone climate control and folding rear seatbacks. Standard technology features include a rearview camera, Audi's MMI infotainment system with a 7-inch central display, Apple CarPlay and Android Auto integration, and a 10-speaker audio system with two USB ports. The optional Convenience package adds auto-dimming and power-folding side mirrors, keyless ignition and entry, driver-seat memory settings and satellite radio. The next step up is the Premium Plus. You get the Convenience package features as standard, along with 18-inch wheels, LED headlights, sporty (S line) exterior styling flourishes, front and rear parking sensors, and a 19-speaker Bang & Olufsen surround-sound audio system. Audi's blind-spot and rear-facing crash mitigation system, Side Assist and Pre Sense Rear, is also standard. The main option for the Premium Plus is the Navigation and Telematics package. This gets you with Audi Connect online services (includes a 4G LTE connection and Wi-Fi), a digital instrument cluster (Virtual Cockpit) and an upgraded version of MMI with an enhanced 8.3-inch display, navigation, voice controls and fingertip-scrawl recognition.
