40% stiffer and 88 pounds lighter than the old one, the new Audi S5 Cabriolet is a serious performer in the sporty coupe convertible segment. The 3.0-liter V6 swaps out the old supercharger for a turbocharger, and now generates 354 horsepower and 369 lb-ft of torque. Power gets sent to all wheels via quattro AWD, with only a ZF-based 8-speed automatic available to shift gears. The S Sport Package adds red brake calipers, sport adaptive damping, and a sport rear differential. Available safety equipment includes traffic sign recognition, lane keep assist and adaptive cruise with traffic jam assistant.
