The Audi S5 (B9) is an all-wheel drive coupé, sportback, & cabriolet built by Audi from late 2016, after its unveiling in June 2016. Its sportback trim adds rear doors and a hatchback rear.

It is part of the second generation model line following on from the Audi S5 (B8) that had been in production since 2007.

As part of the refresh, the new S5 has undergone some major front and rear end changes, including a drop in weight to 1,615 kilograms (Coupé) and a complete redesign of the headlights and bonnet, LED front and rear lighting, sharper body lines, and a new larger one piece grille. There are also a number of optional safety options available such as drive assist and head up display.

Inside, the S5 also receives some new features. A redesigned dashboard and centre console, updated tablet style 8" Audi MMI, Virtual Cockpit (Optional), and features Google Earth maps and Apple CarPlay. The new Audi S5 also has new electrically adjustable front heated seats with cross stitching, and has an optional flat-bottom steering wheel style with circular airbag cover as well as a variety of trim options.

Fitted with a completely new and more powerful 3-litre V6 petrol engine, the S5 has direct injection as well as a twin-scroll turbocharger to reduce both weight, and cost. The turbocharger is mounted within the engine V and as a result has reduced turbo lag response times.

The quattro all-wheel drive system receives power through a locking centre differential that splits torque sent to the wheels at 40% to the front and 60% to the rear. The system can also divert up to 70% to the front or up to 85% to the rear.

0-60 time is around 4.0 seconds (coupé & sportback), with a limited top speed of 155 mph.
