About the 2018 Audi S5 Cabriolet

The second-generation S5 Cabriolet represents Audi's refined approach to open-air performance, trading the beloved naturally aspirated V8 for a more efficient 3.0-liter turbocharged V6 producing 354 horsepower. While purists mourned the loss of that distinctive V8 soundtrack, the new powerplant delivers superior torque delivery and fuel economy without sacrificing the S5's trademark sophistication. The soft-top mechanism operates in just 15 seconds at speeds up to 31 mph, revealing a beautifully appointed cabin with Audi's latest MMI infotainment. Quattro all-wheel drive ensures confident handling regardless of conditions, while adaptive dampers provide the perfect balance between comfort and sport. Production ended in 2023 as Audi transitioned toward electrification, making these final gasoline-powered S5 Cabriolets increasingly appealing to collectors seeking the last of an era. Clean examples with desirable options like the sport differential are already showing strong residual values.
