Why it stands out

The 2018 Audi Q3 stands out as a compact luxury SUV that leans more toward comfort and refinement than outright performance. In its first generation, the Q3 had a softer suspension that made it less capable at cornering, but it was more comfortable. That same character helps explain its appeal: it offers a quiet, polished driving experience in a smaller package, with the refined interior and comfortable ride that many shoppers expect from Audi.

For 2018, the first-generation Q3’s final year, heated seats were added to the Premium trim and the top Prestige trim was discontinued, with most of its features made available as options. That makes this model year notable for buyers who want a well-equipped version of the Q3 without moving to a larger SUV. Standard equipment on the 2018-era first-generation Q3 included leather upholstery, heated front seats, dual-zone automatic climate control, a 7-inch infotainment screen that rose from the dashboard, and a panoramic sunroof, while the Prestige trim had previously added features such as a navigation system, a 14-speaker Bose audio system, a Wi-Fi hotspot, parking proximity sensors, a rear-view camera, and blind-spot monitors.

The tradeoff is that the 2018 Audi Q3 is not the most spacious or most athletic choice in its class. The source notes that some rivals have more rear-seat space, and the Q3’s powertrain was described as fairly unimpressive. Even so, it remains appealing for shoppers who value a premium feel, useful safety equipment, and a compact footprint over maximum cargo room or performance.
